BETA Group, Inc. Page 1 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. Background The Federal Highway Administration defines a Road Safety Audit (RSA) as the formal safety examination of an existing or future road or intersection by an independent, multidisciplinary team. The purpose of an RSA is to identify potential safety issues and possible opportunities for safety improvements considering all roadway users. A Road Safety Audit was scheduled for four intersections along the Route 38 corridor: Rogers Street (Route 38) at Phoenix Avenue and Douglas Road, Rogers Street (Route 38) at Boylston Street, Nesmith Street (Route 38) at Andover Street (Route 133/110), and Nesmith Street (Route 38) at East Merrimack Street. All four intersections have been identified as high crash locations by the Northern Middlesex Council of Governments (NMCOG). The RSA is intended to identify both short and long term safety improvements that can be made at the subject intersections. Project Description Route 38, shown in Figure 1, is a major arterial serving northern Middlesex County. Rogers Street carries the Route 38 designation in a primarily northwest to southeast alignment from I-495 and Tewksbury into Lowell. Route 38 follows Nesmith Street northward from the Nesmith Street/Rogers Street intersection into downtown Lowell, then continues across the Merrimack River, joining with VFW Highway before turning right and following Bridge Street to Dracut and southern New Hampshire. Rogers Street and Nesmith Street are both classified as Urban Principal Arterials. Rogers Street is state-owned from the Tewksbury/Lowell town/city line to just north of Douglas Road and Phoenix Avenue. The remainder of Rogers Street is City owned, as is Nesmith Street from Rogers Street to north of East Merrimack Street. ATR data were obtained from MassDOT for both Rogers Street and Nesmith Street. The Average Daily Traffic (ADT) for Rogers Street was recorded in 2006 north of Boylston Street and showed 25,600 vehicles per day (vpd). Nesmith Street has a 2009 ADT of 29,700 vpd, which was recorded north of East Merrimack Street. The four signalized intersections included in the audit are discussed in detail below. Rogers Street/Phoenix Avenue/Douglas Road Rogers Street, Phoenix Avenue and Douglas Road form a 4-way intersection under traffic signal control. Rogers Street runs northwest to southeast at this location, with Douglas Road approaching from the northeast and Phoenix Avenue approaching from the southwest. Douglas Road is an Urban Collector which provides access to the residential area bordered by Route 38 to the south and west and by Route 133 to the north. Douglas Road also provides access to Reilly Elementary School and Sullivan Middle School. Phoenix Avenue is a local road which ends approximately 1,500 feet from Rogers Street. Phoenix Avenue provides access to several industrial facilities and connects to a driveway for the Hannaford Supermarket, which has its primary access from Rogers Street. Douglas Street and Phoenix Avenue are City-owned roadways. The intersection is under traffic signal control with a concurrent pedestrian phase and a protected lead phase for southbound left turning vehicles bound for Douglas Road. Rogers Street provides two general Page 2 ³ 38 " ) " ) 110 E.

Phoenix Avenue provides two approach lanes, one shared for left and through vehicles and one exclusive lane for right-turning vehicles. Douglas Road provides a single approach lane to Rogers Street. Rogers Street provides two continuous travel lanes in each direction from the intersection south to I-495, but narrows immediately north of the intersection to provide a single travel lane in each direction. An exclusive pedestrian phase is provided at the intersection, but pushbuttons and pedestrian indications are only provided for the Rogers Street Northbound at crosswalk crossing Rogers Street. Phoenix Avenue/Douglas Road There are crosswalks crossing both Douglas Road and Phoenix Avenue without pedestrian signal accommodations. A continuous sidewalk is provided along the eastern side of Rogers Street. There is a continuous sidewalk along the west side of Rogers Street south of the intersection, with the exception of a small section between the driveways at the Sunoco gas station on the southwest corner of the intersection. Land use in the immediate vicinity of the intersection is primarily commercial, with a bank, pizza parlor, multi-use building, and car dealership. Crash data were obtained from the Lowell Police Department for the period from January 2006 to October 2009. The data show a total of eight crashes at the intersection. Four of the crashes were angletype crashes and three were rear-end crashes. Three of the angle-type crashes involved conflicts with vehicles entering or exiting area businesses; two at the Sunoco driveway on the southwest corner of the intersection, the other at the car dealership just south of the intersection. It was noted during the audit that there were a higher number of recorded crashes in previous years, although no significant change at the intersection could be attributed to the reduction in crashes. The intersection ranks 47th on NMCOG’s Top 100 Crash Intersections in the Northern Middlesex Region, 2004-2006. A summary of crash data and a collision diagram are included in the Appendix. Rogers Street/Boylston Street/Fairmount Street/Laurel Street Rogers Street, Boylston Street, Fairmount Street and Laurel Street form a 4-way intersection under traffic signal control. Boylston Street is an Urban Minor Arterial which provides access to several residential neighborhoods and extends into Tewksbury. Fairmount Street runs essentially parallel to Rogers Street. Both Fairmount Street and Laurel Road provide access to residential areas north and east of Rogers Street. All roadways at the intersection are City-owned. There are three channelization islands separating Laurel Road, Fairmount Street and Rogers Street. These islands prevent a direct connection to Fairmount Street from Rogers Street northbound, discouraging the use of Fairmount Street as a cut-through route. Page 4 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. The islands also allow traffic from both Fairmount Street and Laurel Road to merge into a single approach to the signalized intersection at Rogers Street and Boylston Street. Rogers Street provides two lanes in each direction at the intersection. There is an exclusive left turn lane and a shared through/right turn lane northbound, and a shared left/through and an exclusive right turn lane southbound. Boylston Street provides a single lane approach. The combined approach of Fairmount Street and Laurel Street has a single approach lane and a single departure lane. Pavement markings are faded at the intersection. There are crosswalks on all four approaches with an exclusive pedestrian phase. Pedestrian pushbuttons and signals were found to be missing or malfunctioning for three of Rogers Street Southbound approach at Boylston Street the four approaches. The intersection operates under lead/lag phasing for the Rogers Street approaches, although there are no signal heads indicating when the protected lead or lag phase is active. Land use in the immediate vicinity of the intersection is a mix of residential, commercial, municipal and recreational. There is a former fire station on the northeast corner of the intersection which is no longer used as an active station but is still used by the Lowell Fire Department for offices and training. Shedd Park is on the northwest corner of the intersection. Crash data were obtained from the Lowell Police Department for the period from January 2006 to June 2009. The data show a total of 31 crashes. 15 of the 31 crashes were rear-end crashes, with seven of those 15 occurring on the Rogers Street southbound approach. There were three rear-end crashes on the Rogers Street northbound approach. It was suggested during the audit that the lack of signal indications for the exclusive lead and lag phases may contribute to the prevalence of rear-end crashes at this location. There were four angle-type crashes involving left-turning vehicles from Rogers Street colliding with a through vehicle traveling in the opposite direction. The intersection ranks 43rd on NMCOG’s Top 100 Crash Intersections in the Northern Middlesex Region, 2004-2006. A summary of crash data and a collision diagram are included in the Appendix. Nesmith Street/Andover Street Nesmith Street and Andover Street form a 4-way intersection under traffic signal control, and is the intersection of three state numbered routes. Route 38 follows Nesmith Street through the intersection, Route 110 follows Andover Street to the west and Nesmith Street to the north, and Route 133 follows Andover Street to the east but terminates at the intersection. Andover Street is an Urban Principal Arterial owned by the City, although the traffic signal is state-owned. Andover Street provides access to Page 5 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. downtown Lowell to the west and to Tewksbury and Andover to the east. Land use is primarily residential in the immediate vicinity of the intersection. Nesmith Street provides two lanes in each direction at the intersection, with an exclusive left turn lane a shared through/right lane in each direction. Andover Street also provides two lanes in each direction, with a shared left/through lane and an exclusive right turn lane westbound and two general purpose lanes eastbound. Andover Street has a steep downhill grade westbound, which causes some visibility Andover Street westbound at Nesmith Street issues for approaching vehicles and may contribute to crashes in winter conditions. There are continuous sidewalks on both sides of both Nesmith Street and Andover Street and there is an exclusive pedestrian phase with crosswalks, pushbuttons and pedestrian signals for all four approaches. A lead phase is provided for the southbound left turn with arrow indications, and an overlap for the westbound right turn. An exclusive phase is not provided for the northbound left turn, although it does have a separate turn lane. Crash data were obtained from the Lowell Police Department for the period from January 2006 to August 2009. The data show a total of 44 crashes. 13 of the 44 crashes were rear-end crashes, while 23 were angle-type crashes. Seven of the angle-type crashes involved a collision between through vehicles and opposing left-turning vehicles on Nesmith Street. Three involved a northbound through vehicle colliding with a southbound left turn vehicle, while four involved a northbound left turning vehicle and a southbound through vehicle. Four crashes were attributed to sliding due to snow or ice, one in each travel direction. There was one crash involving a bicycle at the intersection, in which an eastbound left turning vehicle struck a bicycle which was also traveling eastbound. The intersection ranks 9th on NMCOG’s Top 100 Crash Intersections in the Northern Middlesex Region, 2004-2006. The intersection also ranked 189th on MassDOT’s statewide list of the Top Crash Intersections from 2005 to 2007. This ranking is based on the number and severity of crashes in MassDOT’s database which can be geolocated to a cluster area around the intersection. This cluster area experienced 62 crashes in the three year period. The ranking is then determined using a weighted system which calculates the Equivalent Property Damage Only (EPDO) rating of the intersection. Fatal crashes are weighted 10 times and injury crashes are weighted 5 times. Thirteen of the 62 crashes involved an injury. There were no fatal crashes in the three year study period. A summary of crash data and a collision diagram are included in the Appendix. Nesmith Street/East Merrimack Street Nesmith Street and East Merrimack Street form a 4-way intersection under traffic signal control. East Merrimack Street is an Urban Principal Arterial owned by the City, although the traffic signal is stateowned. East Merrimack Street provides access to downtown Lowell to the west and connects to a Page 6 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. network of residential streets to the east. Land use is primarily residential in the immediate vicinity of the intersection, with the Saints Medical Center hospital complex on the northwest corner of the intersection. Nesmith Street provides two general purpose lanes in each direction at the intersection. A small island on the southbound approach separates the right turn towards downtown Lowell, which is under yield control. East Merrimack Street provides one general purpose lane westbound and two lanes eastbound, which are marked as one exclusive left turn lane and an unmarked shared through/right turn lane. It was noted during the audit that vehicles often use the right lane for left turns, creating a de facto dual left turn lane. It was also noted that Nesmith Street south of the intersection is not wide enough for two departure lanes, and that there is an A vehicle crosses the center line on Nesmith Street orange “Road Narrows” sign that is south of East Merrimack Street largely ignored as vehicles straddle the double yellow center line in order to maintain two through lanes to Andover Street. Continuous sidewalks are provided on both sides of both Nesmith Street and East Merrimack Street and there is an exclusive pedestrian phase with crosswalks, pushbuttons and pedestrian signals for all four approaches. A lead phase is provided for the northbound left turn with arrow indications. Crash data were obtained from the Lowell Police Department for the period from March 2006 to May 2009. The data show a total of 22 crashes. 11 of the crashes were angle-type crashes, with six of those crashes occurring between a through vehicle and an opposing left-turning vehicle on Nesmith Street. Five of the 22 crashes were rear-end crashes, two of which occurred departing the intersection southbound, where drivers are known to straddle the center line to maintain two lanes. Two crashes at the intersection were the result of vehicles pulling over for an emergency vehicle or re-entering the traffic stream after pulling over for an emergency vehicle. One crash involved a pedestrian who was struck by an eastbound vehicle on East Merrimack Street. The intersection ranks 33rd on NMCOG’s Top 100 Crash Intersections in the Northern Middlesex Region, 2004-2006. A summary of crash data and a collision diagram are included in the Appendix. Page 7 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. Audit Observations Following a brief introduction to the RSA process and a summary of existing geometry and crash information, the audit participants were asked to discuss issues that may affect safety at the four subject intersections and along the Route 38 corridor. Audit participants then visited each of the four intersections as a group, at which time they offered observations on safety concerns and deficiencies. A summary of those major safety considerations is as follows, summarized by location: Rogers Street/Phoenix Avenue/Douglas Road • • • • • • • Pavement Markings – Pavement markings are faded at the intersection, which decreases visibility of defined lane use. Pedestrian Accommodations – Pedestrian signals and pushbuttons are provided for the crosswalk crossing Rogers Street, but not for the marked crosswalks crossing Douglas Road and Phoenix Avenue. Fiber optic Pedestrian Signals – Pedestrian heads at this intersection are older, single section fiber optic heads. Newer LED technology provides increased visibility. Faded pavement markings at Rogers Street and Phoenix Road Signage on Rogers Street approaches – It was noted by an audit participant that advance street name signs were installed on the Rogers Street northbound approach only; however, BETA confirmed that an advance street name sign is provided for the southbound approach as well. Visibility of signal – It was suggested that the crest vertical curve north of the intersection may limit visibility of the signal at Phoenix Avenue and Douglas Road from the Rogers Street southbound approach. “Don’t Walk” pedestrian indication out – At the time of the audit, the “Don’t Walk” indication on the southwest corner of the intersection was not functioning. This is likely the result of a burnt out module, which should be repaired immediately to reinstate proper operation of pedestrian signals. Catch basin filled in – It was noted by an audit participant that the catch basin on the northwest corner of the intersection was filled with sediment and debris. While no drainage issues were noted, the blocked catch basin may cause slower water runoff and may lead to ponding. Poor runoff and Page 8 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. ponding may also contribute to ice buildup along the roadway gutter, potentially impacting wheelchair ramps. • • Break in continuous sidewalk – A continuous sidewalk is provided along the east side of Rogers Street on both sides of Douglas Road and along the west side of Rogers Street south of Phoenix Avenue, except for a small piece of sidewalk between the driveways of the Sunoco gas station on the southwest corner of the intersection. It was suggested by an audit participant that right-of-way limitations prevented the construction of sidewalk in this area. Break in sidewalk at Sunoco Station Parking areas – There are parking areas on both sides of Douglas Road that have no separation from the roadway and require vehicles to back into the road to exit. It should be noted that none of the crashes at this intersection were directly attributed to these parking areas and that other parking options exist for the businesses served by them. Rogers Street/Boylston Street/Fairmount Street/Laurel Street • • • • Do Not Enter signage – It was noted that the existing Do Not Enter sign at the island separating Laurel Street from Fairmount Street is misaligned and that a second sign should be provided on the island on the opposite side of the roadway. In its current alignment, the sign may confuse a driver heading towards Rogers Street on Laurel Street. Pavement Markings - Pavement markings are faded at the intersection, which decreases visibility of defined lane use. It was also noted that one-way roadways between islands should have yellow markings on the left side, which would help confirm the one-way configuration. Pedestrian Accommodations – Pedestrian signals and pushbuttons are provided for all crosswalks but were noted to be malfunctioning. Pushbuttons are missing or non-functioning, and some pedestrian signal indications were out. Signal posts damaged, signal heads misaligned – The signal post on the northeast corner of the intersection appears to have been struck, resulting in damage to the components. The base cover is not attached and the pole is not stable, indicating that the bolts holding it to the foundation are missing or broken. It was also noted that a signal head on the northwest corner had bent visors, likely Page 9 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. the result of being struck by a passing vehicle. In addition to damage to posts and heads, it was noted that several signal heads were misaligned so that they are not directly facing traffic flow. • • • • • No handicap ramp on the northeast corner – Crosswalks and handicap access ramps are provided for all approaches and all corners, with the exception of the northeast corner in front of the fire station, where there is no handicap ramp for the crosswalk crossing the Fairmount Street approach. A separate ramp is provided further north on this corner for the crosswalk crossing the northern Rogers Street approach Signal visibility – The lack of backplates was cited as a safety Lack of handicap ramp on the northeast corner of concern. Installation of Rogers Street and Farimount Street backplates would increase visibility of the signal indications for approaching vehicles. Signal Phasing – The existing signal phasing provides lead-lag phasing for the Rogers Street approaches but with no signal indications to identify when the exclusive phase is in operation. The addition of signal head indications and the modification of existing phasing would reinforce when left turning vehicles have an exclusive phase and may help to reduce the number of conflicts between left turning vehicles and opposing through vehicles. Fire Station Signal –An existing emergency related post mounted traffic signal on Fairmount Street is provided for vehicles approaching the fire station from the north. This signal typically shows the same indication as the Fairmount Street signals at Rogers Street, but displays a red indication when triggered by a loop under the fire station driveway. The fire station is used as a training facility but is no longer used for active response to fire emergencies. Despite the station being inactive, the signal still operates as intended, which was observed during the audit when a car parked in the fire station driveway caused the signal to stay red. Several vehicles were observed ignoring the signal indication. This signal should be removed to avoid confusion for approaching motorists. Corridor Delineation – Rogers Street north of the intersection is striped to provide one single travel lane in each direction, with the southbound approach widening to provide two lanes at Boylston Street. This may lead to aggressive drivers attempting to create a second travel lane by straddling the double yellow center line. The corridor should be clearly delineated as one lane in each direction with a wider marked shoulder, or delineated as two travel lanes where appropriate width exists. Page 10 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. • Parking – Shedd Park is a recreational facility on the northwest corner of the intersection with athletic fields and courts as well as a playground. It was noted by audit participants that there is a large demand for parking at the park, specifically in the summer months, and that vehicles have been known to park along Rogers Street near Boylston Street. The City has placed No Parking signs along all streets in the vicinity of the intersection. Nesmith Street/Andover Street • • • • • Pavement Markings – Pavement markings are faded at the intersection, which decreases visibility of defined lane use. Debris and ice buildup at handicap ramp – There is a catch basin immediately to the east of the handicap ramp on the southeast corner of the intersection. Due to the grade of Andover Street, water which is not captured by this catch basin runs directly across the ramp opening. Debris and ice was observed at the ramp opening on the day of the audit, creating a safety hazard for pedestrians. Debris and ice in handicap ramp Handicap Access – The ramp at the southwest corner of the intersection is not properly aligned with the crosswalk. Instead it directs pedestrians into the center of the intersection, creating a potential safety issue for vision impaired pedestrians. Narrow Nesmith Street cross section – The section of Nesmith Street between Andover Street and East Merrimack Street provides a single travel lane in each direction, with exclusive left turn lanes at each intersection. During peak traffic periods, vehicles have been observed straddling the double yellow center line to provide two de facto through lanes in either direction, creating a safety hazard. Existing features such as the adjacent Kittredge Park east of Nesmith Street and right-of-way restrictions limit the opportunity for widening of this roadway segment. This safety issue also relates to the Nesmith Street/East Merrimack Street intersection. Visibility – It was noted that visibility is poor for vehicles on Andover Street and for left turning vehicles on Nesmith Street southbound due to the grade of the intersection. It should be noted that the existing topography as well as right-of-way restrictions and proximity of existing properties prevent significant adjustments to vertical alignment. It was suggested that protected only phasing may address visibility issues but would reduce capacity. Page 11 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. • • • • • • • Signal phasing – The southbound left turn lane runs under protected-permissive phasing with a lead phase. No protected phase is provided for northbound left turns. It was suggested that these turns run under protected phases only, although it was noted that this would decrease capacity of the intersection. Signal visibility – The lack of backplates was cited as a safety concern. Installation of backplates would increase visibility of the signal indications for approaching vehicles. Fiber optic Pedestrian Signals – Pedestrian heads at this intersection are older, single section fiber optic heads. Newer LED technology provides increased visibility. Mast arm mounted sign alignment – The mast arm mounted R3-5L (Left Only) signs are tilted due to the angle of the mast arm. This reduces visibility of the signs for approaching vehicles on Nesmith Street, and makes the sign visible for Andover Street westbound traffic, which does not have an exclusive left turn lane. This may cause confusion for approaching motorists on Andover Street. It was noted by MassDOT District 4 personnel that the brackets used for the sign mounting make it difficult to align them properly, and that a different type of bracket would allow more precise adjustment but could lower the signs such that they do not meet minimum vertical clearance requirements. Utility pole on northwest corner – It was noted by audit participants that the utility pole on the northwest corner of the intersection has been struck several times, which was evident by visible damage to the pole observed during the audit. The horizontal and vertical alignments of the roadways as well as the location of the pole contribute to this safety issue. Complicated signage – It was noted by an audit participant that the amount of signage at the intersection may be overwhelming and confusing for approaching motorists, particularly on the Nesmith Street northbound approach. Pavement condition – The asphalt pavement at the intersection was placed over concrete and cobblestone base. Visual evidence exists of pavement “shoving” on the Andover Street westbound approach, likely exacerbated by the steep downhill grade. Nesmith Street/East Merrimack Street • • Pavement Markings – Pavement markings are faded at the intersection, which decreases visibility of defined lane use. De facto dual left turn lane eastbound – The East Merrimack Street eastbound approach provides one left turn lane and one shared through/right turn lane; however, vehicles often queue in the right lane to make a left turn, creating a de facto dual left turn lane. This creates a safety issue because the motorist in the left turn lane may not anticipate a vehicle turning left alongside them. Page 12 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. • • • • • • • Driveway into intersection – A multi-family house on the southwest corner of the intersection has a driveway that opens into the center of the intersection. A stop sign is located at the end of the driveway but the driveway is not under signal control. Section 4D.01 of the Manual on Uniform Traffic Control Devices (MUTCD) allows stop signs for this type of application if an extremely low potential for conflict exists. It was noted by MassDOT District 4 that it is not typically MassDOT practice to signalize a driveway under similar conditions. It was also noted by the Driveway at Nesmith Street and East Merrimack City that the property owner Street enters into intersection requested an additional driveway on East Merrimack Street on the western side of the property, but the request was denied due to the impact on the East Merrimack Street approach. Although this driveway presents a safety issue, no crashes were attributed to it and no potential solution could be determined amongst audit participants. Queuing and blocking of intersection – Congestion at this intersection and at nearby intersections during peak periods sometimes prevents vehicles from passing completely through the intersection during the green indication. This creates a safety issue when opposing vehicles are blocked by vehicles still navigating the intersection. Signal phasing – The northbound left turn lane runs under protected-permissive phasing with a lead phase. No protected phase is provided for southbound left turns. It was suggested that these turns run under protected phases only, although it was noted that this would decrease capacity of the intersection. Signal visibility – The lack of backplates was cited as a safety concern. Installation of backplates would increase visibility of the signal indications for approaching vehicles. Fiber optic pedestrian signals – Pedestrian heads at this intersection are older, single section fiber optic heads. Newer LED technology provides increased visibility. Pedestrian Accommodations – Pedestrian signals and pushbuttons are provided for all crosswalks, but the pedestrian signal on the southwest corner was observed to be non-operational. Parking – Parked vehicles were observed on the East Merrimack Street westbound approach in close proximity to the intersection. These vehicles are parked on the existing loops, which may give false Page 13 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. calls to that approach when no vehicles are present. This may decrease the intersection capacity, creating congestion and contributing to related safety issues. • • • Stairs into travel lane – There are a number of houses along the Nesmith Street northbound approach with stairs coming from the house to the sidewalk, which is separated from the edge of the roadway by a green strip. The sidewalk is higher than the roadway, and the stairs for some properties continue to the edge of roadway. This may create a safety hazard if a pedestrian followed the stairs and walked into the roadway instead of following the sidewalk to the protected pedestrian crossing at the intersection corner. Pavement condition – The pavement is showing signs of wear throughout the intersection, including rutting and pavement “shoving” on the Nesmith Street northbound approach, likely exacerbated by the steep downhill grade. Signal Coordination – It was noted during the audit that the intersections of Nesmith Street at Andover Street, Nesmith Street at East Merrimack Street, and Nesmith Street at Stackpole Street were designed as a coordinated Pavement shoving on system. It was noted by audit Nesmith Street northbound approach participants that capacity constraints and vehicle queues prevent the coordination from providing its intended benefit. MassDOT District 4 personnel confirmed after the meeting that coordination is not currently functioning at these three intersections. It was suggested that coordination should be verified and timings revisited, which may potentially improve capacity and reduce congestion. Page 14 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. Potential Safety Enhancements After the site visit, audit participants returned to the meeting location to discuss the safety issues and consider improvements. Audit participants were encouraged to consider both short and long term improvements for each issue. Each improvement considered has been categorized as short-term, midterm, or long-term based on the definitions shown in Table 2. Additionally, a cost category has been assigned to each improvement based on the parameters set forth in Table 2. It should be noted that a resurfacing project is scheduled to begin in 2010 which will resurface Route 38 from the Lowell/Tewksbury city/town line to the Hunts Falls Bridge over the Merrimack River, a total length of 1.83 miles which includes all four intersections included in the audit. The project scope of work includes roadway resurfacing, sidewalk repairing, wheelchair ramp improvements, pavement marking installation, loop detector replacement and temporary timing, where necessary. Table 2. Estimated Time Frame and Costs Breakdown Time Frame Short-term <1 year Mid-term 1–3 years Long-term >3 years Costs Low Medium High <$10,000 $10,001–$50,000 >$50,000 Rogers Street/Phoenix Avenue/Douglas Road The following improvements were suggested by audit participants to improve safety issues associated with the intersection of Rogers Street, Phoenix Avenue and Douglas Road. • • • Reapply pavement markings. This is a short-term, medium cost improvement that will be accomplished as part of the planned resurfacing project. Install LED pedestrian signal heads and pushbuttons for all crosswalks. The crosswalks crossing Douglas Avenue and Phoenix Road should be signalized and operate under the same exclusive pedestrian phase as the existing signalized crosswalk crossing Rogers Street. The existing pedestrian signals should be replaced with LED signal heads, which provide greater visibility. This is a shortterm, medium cost improvement. Conduct a sight distance study of the Rogers Street southbound approach. The Rogers Street southbound approach should be studied to determine if adequate sight distance exists for the signal at Douglas Road and Phoenix Avenue. If adequate sight distance does not exist, an illuminated Red Signal Ahead sign should be added overhead to warn approaching vehicles of the upcoming signal. The sight distance study is a short-term, low cost improvement, while the illuminated Red Signal Ahead sign would be a mid-term, medium cost improvement. Page 15 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. • • Clean catch basins. Catch basins in the vicinity of the intersection should be cleaned of sediment and debris to restore the existing closed drainage system to its intended capacity. In addition to the catch basin on the northwest corner of the intersection discussed during the audit, there is a catch basin on the northeast corner of the intersection and two catch basins at a low point immediately south of the intersection. This is a short-term, low cost improvement that could be completed under an existing MassDOT open-ended maintenance contract (File No. 605163). Install sidewalk along Sunoco property. There is a break in the sidewalk on the west side of Rogers Street south of the intersection between the two driveways accessing the Sunoco gas station on the southwest corner of the intersection. It was assumed during the audit that sidewalk was not provided along this section due to right-of-way impacts; however, older pictures available through Google StreetView show that a continuous concrete path was previously provided. Concrete pavement should be restored in this area to provide a continuous 4 foot minimum width path along the Sunoco property. This is a short-term, low cost improvement that should be included as part of the planned resurfacing project. Rogers Street/Boylston Street/Fairmount Street/Laurel Street • • • Reapply pavement markings. This is a short-term, medium cost improvement that will be accomplished as part of the planned resurfacing project. The limits of the resurfacing project should be examined to determine if new pavement markings will be extended along the approaches of Boylston Street, Fairmount Street and Laurel Street. If these approaches are not included in the resurfacing project, it will be the City’s responsibility to reapply markings on these approaches, including yellow markings along the left side of all one way channelized roadways. Adjust/Update signage. The existing Do Not Enter sign on the island separating Laurel Street from Fairmount Street is misaligned and may lead to driver confusion. This sign should be reset so that the sign panel is closer to and perpendicular to the channelized roadway it applies to, and an additional sign should be added on the island on the opposite side of the roadway to confirm which roadway it applies to. This is a short-term, low cost improvement. Update pedestrian signals. Pedestrian accommodations at the Misaligned Do Not Enter sign intersection were found to be either malfunctioning or inoperable. All pushbuttons and pedestrian signal heads should be repaired or replaced as needed. Pedestrian signal Page 16 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. heads to be replaced should be replaced with LED signal heads. This is a short-term, medium cost improvement. • • • • • • • • Repair signal post and adjust signal heads. The signal post on the northeast corner of the intersection should be repaired or replaced so that the post is firmly attached to its foundation and the base is closed and fastened. All signal heads should be examined to determine if they face traffic as intended, and adjusted as needed. Damaged signal head visors should be repaired or replaced. This is a short-term, medium cost improvement. Install handicap ramp. The sidewalk should be modified on the northeast corner of the intersection to provide a handicap ramp for the crosswalk crossing the Fairmount Street approach. This is a shortterm, medium cost improvement that should be considered in conjunction with the planned resurfacing project. Install backplates. Backplates should be installed on all overhead signal heads. This is a short-term, low cost improvement. It should be noted that structural calculations would be required to determine if backplates can be supported by the existing structures, and that the outcome of said calculations could increase the cost and complexity of this improvement. Study intersection, adjust signal phasing and install arrow indications. The existing lead-lag phasing for the Rogers Street approaches causes confusion amongst drivers because there are no arrow indications to designate when an exclusive phase is in operation. An intersection study should be performed to determine optimum phasing for the intersection. The phasing update may consider exclusive advance left turn phases in place of lead-lag phasing. If exclusive phases are to be provided or maintained, new signal heads with arrow indications should be installed. This is a mid-term, medium cost improvement. Remove signal post for fire station. There is an existing signal post on Fairmount Street which is preempted with a red signal whenever a vehicle uses the fire station garage driveway. This signal post should be removed since the fire station is no longer used for active calls, and the sidewalk should be patched as needed. This is a short-term, low cost improvement. Upgrade traffic signal. A number of short-term improvements discussed in this report could be combined into a single, comprehensive traffic signal reconstruction project. This would be a midterm, high cost improvement. Delineate corridor. The Rogers Street corridor should be restriped north of Boylston Street to clearly define the number of lanes provided and discourage vehicles from making a de facto second travel lane. A 6 foot wide shoulder should be marked in all sections where there is intended to be a single travel lane. This is a short-term, medium cost improvement which should be completed as part of the planned resurfacing project. Add directional parking signs. There is a large demand for parking for Shedd Park, located on the northwest corner of the intersection. The location of available parking is not readily apparent from Rogers Street. Directional parking Page 17 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. signs should be added to direct vehicles to available parking. This is a short-term, low cost improvement. Nesmith Street/Andover Street • • • • • • Reapply pavement markings. This is a short-term, medium cost improvement that will be accomplished as part of the planned resurfacing project. Clean catch basins. Catch basins in the vicinity of the intersection should be cleaned of sediment and debris to restore the existing closed drainage system to its intended capacity. This is a short-term, low cost improvement that should be included under an existing MassDOT open-ended maintenance contract (File No. 605163). Realign handicap ramp. The handicap ramp on the southwest corner is not properly aligned with the crosswalk and instead directs pedestrians into the center of the intersection. This crosswalk should be reconstructed so that it is properly aligned with the crosswalk, in accordance with current MassDOT standards. This is a short-term, low cost improvement. Widen Nesmith Street. The portion of Nesmith Street between Andover Street and East Merrimack Street provides one travel lane in each direction with an exclusive left turn lane at each intersection. Vehicles have been observed straddling the double yellow center line to create two travel lanes in either direction during peak periods, suggesting that the existing configuration does not meet current operational demands. It was suggested by an audit participant that this roadway segment should be widened to provide two travel lanes in each direction. This would require a minimum of ten feet of widening, which would create significant right-of-way and grading impacts, as well as impacts to the adjacent Kittredge Park. It was suggested by an audit participant that the sidewalk along the east side of Nesmith Street could potentially be relocated to and integrated with the park. This is a mid-term, high cost improvement that would require land takings. Study intersection and adjust signal phasing. There is an existing lead phase for southbound left turns, with no protected phase for northbound lefts. It was suggested that northbound and southbound left turns be provided with a protected phase only, which would improve safety at the intersection by reducing conflicting movements but would decrease capacity. An intersection study should be performed to determine the impacts of this potential change. Signal timing and phasing should be adjusted based on the outcome of the study. If an exclusive left turn phase is to be added for northbound left turns, a new signal head with arrow indications should be installed. This is a midterm, medium cost improvement. This should be considered in conjunction with widening, which would provide increased potential to correct capacity deficiencies. Install backplates. Backplates should be installed on all overhead signal heads. This is a short-term, low cost improvement. It should be noted that structural calculations would be required to determine if backplates can be supported by the existing structures, and that the outcome of said calculations could increase the cost and complexity of this improvement. Page 18 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. • • • • • Install LED pedestrian signal heads. All existing fiber optic pedestrian signals should be replaced with LED signal heads, which provide greater visibility. This is a short-term, medium cost improvement. Upgrade traffic signal. The A number of short-term improvements discussed in this report could be combined into a single, comprehensive traffic signal reconstruction project. The existing signal equipment could be replaced with four mast arms, one placed on each corner perpendicular to the roadway. This would also address the issue of the misaligned Left Only signs on the existing mast arms. This would be a mid-term, high cost improvement. Relocate utility pole on northwest corner. The existing location of the utility pole on the southwest corner of the intersection is such that a wide turn or a slightly errant turn for a northbound left turning vehicle may result in a collision. The pole should be relocated further west, if possible. This is a short-term, low cost improvement that will require coordination with National Grid to determine its feasibility. Resurface Nesmith Street and Andover Street approaches. This will be accomplished under the planned resurfacing project. The limits of the project should be explored to determine if they include an adequate length along the Andover Street approaches to repair known pavement shoving issues. Remove/relocate private signs. It was noted by an audit participant that the amount of signage at the intersection may be overwhelming and confusing for approaching motorists. The existing R3-7L (Left Lane Must Turn Left) signs are appropriate for the existing lane configuration, and the existing guide signage is necessary given the confluence of three state numbered routes at the intersection. The destination signage for cultural, historical and recreational locations in Lowell is beneficial and is part of a system of signs directing motorists. While all these signs should be retained, any private signs within 300 feet of the intersection should be relocated or removed. This is a short-term, low cost improvement. Nesmith Street/East Merrimack Street • • Reapply pavement markings. This is a short-term, medium cost improvement that will be accomplished as part of the planned resurfacing project. Study intersection and adjust signal phasing. There is an existing lead phase for northbound left turns, with no protected phase for southbound lefts. It was suggested that northbound and southbound left turns be provided with a protected phase only, which would improve safety at the intersection by reducing conflicting movements but would decrease capacity. An intersection study should be performed to determine the impacts of this potential change. Signal timing and phasing should be adjusted based on the outcome of the study. If an exclusive left turn phase is to be added for northbound left turns, a new signal head with arrow indications should be installed. This is a midterm, medium cost improvement. A comprehensive corridor study should be considered incorporating Andover Street, East Merrimack Street and Stackpole Street to investigate coordination and make necessary adjustments. Page 19 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. • • • • • • • • Install lane configuration signs for East Merrimack Street approach. The eastbound East Merrimack Street approach provides an exclusive left turn lane and a shared through/right turn lane, although vehicles are known to create a dual left turn lane by making left turns from the right lane. R3-8 series lane configuration signs should be added to confirm the existing lane configuration. This is a short-term, low cost improvement that should be supplemented with increased police enforcement. Police enforcement carries no additional cost, but would result in decreased enforcement elsewhere in the City. Left turn capacity should be investigated as part of the intersection study recommendation, and resulting recommendations for improving left turn capacity should be incorporated into a long term improvement plan for the intersection. Install “Do Not Block Intersection” signs. Congestion in the area creates queue issues during peak periods, which may result in vehicles stacked through the intersection during signal phase changes. R10-7 “Do Not Block Intersection” signs should be added on all four approaches. This is a short-term, low cost improvement. Install backplates. Backplates should be installed on all overhead signal heads. This is a short-term, low cost improvement. It should be noted that structural calculations would be required to determine if backplates can be supported by the existing structures, and that the outcome of said calculations could increase the cost and complexity of this improvement. Install LED pedestrian signal heads. All existing fiber optic pedestrian signals should be replaced with LED signal heads, which provide greater visibility. This is a short-term, medium cost improvement. Upgrade traffic signal. A number of short-term improvements discussed in this report could be combined into a single, comprehensive traffic signal reconstruction project. The existing span wire could be replaced with mast arms. This would be a mid-term, high cost improvement. Enforce No Parking areas. Vehicles were observed to be parked on the existing loops on the East Merrimack Street westbound approach, where there are existing No Parking signs. This area should be targeted for enforcement of parking restrictions. This is a short-term improvement with no cost, except for the cost of potential reduced enforcement elsewhere. Remove stairs. Stairs between the sidewalk and roadway on the east side of Nesmith Street south of the intersection should be removed if they are in the Nesmith Street right-of-way. Pedestrians should be encouraged to use the existing sidewalk to access designated, protected crossings instead of walking directly into the street. This is a short-term, medium cost improvement. Stairs would be removed and replaced with grass to match the existing grass strip separating the roadway from the sidewalk. Resurface Nesmith Street and East Merrimack Street approaches. This will be accomplished under the planned resurfacing project. The limits of the project should be explored to determine if they include an adequate length along the East Merrimack Street approaches to repair known pavement shoving issues. Page 20 Road Safety Audit—Route 38 Corridor – Lowell, MA Prepared by BETA Group, Inc. Summary of Road Safety Audit Table 3 summarizes potential recommendations discussed by the audit team.
