City of Eden Prairie Pedestrian and Bicycle Plan Toolbox of Pedestrian and Bicycle Treatments and Best Practices Final Report Best Practices for Pedestrian and Bicycle Infrastructure Introduction Walking and bicycling are two healthful, affordable and convivial activities that can fulfill transportation and recreation functions while enhancing the qualities of those places where they are accommodated. Cities large and small are rethinking their approaches to mobility to better integrate walking and bicycling into their fabric, and exploring new approaches for maximizing sustainability and prosperity while improving quality of life for their residents. This Pedestrian and Bicycle Plan, funded by Hennepin County and sponsored by the City of Eden Prairie, aims to provide a best practices-based approach toward the development and step-by-step implementation of solutions that make it easier, safer, more comfortable and more convenient for residents of Eden Prairie to integrate walking and cycling into their daily lives. The soon-to-be-realized SW LRT line - with five stations planned within the city - offers Eden Prairie an ideal opportunity to build on its assets, expand transportation choices, and create convenient city connections that allow residents to comfortably and conveniently incorporate Active Transportation into their daily routines. A network of interconnected bikeways and walkways, tightly integrated with access to and from the new SW LRT stations, will help Eden Prairie meet its goals of becoming a more vibrant, connected and prosperous city. This report includes a description of best practices for the development of infrastructure for walking and bicycling. The tools and approaches included are based on a survey of national applications and case studies, and provide guidance for improvements to street cross sections, intersections, and signals to make walking and biking safer, more inviting, more comfortable and more convenient. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report Walking and biking are fun, healthy and enjoyable activities that benefit individuals and communities. Well-Designed Infrastructure Invites Walking and Bicycling • Well-designed pedestrian and bicycling infrastructure - dedicated pedestrian and bicycling routes, signals, signage, and others - makes walking and bicycling safer, and more convenient, comfortable, and inviting. • Cities, neighborhoods, and communities that offer high quality pedestrian and bicycle infrastructure experience higher rates of bicycling and walking. Purpose of this Guide This document is intended as a resource in selecting and implementing pedestrian and bicycle infrastructure. It is not intended to define specific standards or practices for the City of Eden Prairie. 1 Best Practices for Walking: Sidewalks Description Sidewalks designate space for the exclusive use of pedestrians, and are a foundational element for a system of pedestrian mobility. They are also a vital component of healthy commercial districts, providing access to businesses, space for street furniture and plantings, and for the casual interactions that support community interpersonal connections. Well-designed sidewalks provide four distinct “zones” that allow them to function in different contexts, with dimensions that respond to the the land uses and locations they serve. The four zones are: • The pedestrian zone is the zone where people walk. This zone should accommodate people with varying mobility and allow them to navigate the city or district safely and comfortably. Width for a main street / commercial district should be between 6 to 8 ft. Width for a residential district should be at least 5 ft. • The frontage zone is the portion of the sidewalk that provides access to businesses or other uses adjacent to the sidewalk. It is also the space that can be used for outdoor seating for cafés or restaurants in commercial districts. A minimum of 2.5 ft is recommended for store access, with greater widths to accommodate seating. • The furniture zone is the portion of the sidewalk where trees, newspaper stands, benches, signs and trash receptacles are placed. Part of its usefulness is that these important elements are placed where they donʼt obstruct the mobility of people walking or in wheelchairs. In addition, this zone increases the distance between the pedestrian zone and moving motor-vehicles - increasing comfort and sense of safety for people on foot. Sidewalk zones in a commercial district. Design guidance • Minimum width recommendation for a sidewalkʼs pedestrian zone is 6 ft wide in a commercial district, and 5 ft in a residential district; and • Sidewalks should be in good condition and free of obstructions. separation between automobiles and pedestrians. Application of Facility • Sidewalks should be considered in residential neighborhoods, commercial districts, near schools, and all other locations where pedestrians desire access. Sidewalks should connect pedestrians to businesses, parks, schools, and other amenities through a comprehensive network of routes. • The curb zone is the outermost edge of the pedestrian realm and is generally raised above the motor-vehicle travelway to create a defined and safe Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 2 Best Practices for Walking: Curb Ramps Description Curb ramps allow wheelchair users, people with sight or mobility impairments, and parents using strollers to easily enter and exit sidewalks and pedestrian crossings. They also make walking generally more comfortable and safer for all pedestrians. They should be used at all locations where pedestrians are expected to cross. The recommended practice is to provide two perpendicular ramps (rather than a single one at a corner) to better accommodate wheelchair users and reduce conflicts with motor-vehicle traffic. Application of Facility • Curb ramps should be included at all locations where Perpendicular curb ramps. pedestrians are expected to cross. Design guidance • Preferred design is to provide two perpendicular ramps rather than one on the corner in order to better place wheelchair users and reduce conflicts with traffic; • The slope of a ramp should be no greater than 8.3%; • Ramp width is a minimum of 48”, with a corresponding landing of equal width; and • Detectable warnings must be included for people with vision impairments. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 3 Best Practices for Walking: High-Visibility Crosswalk Description Marked crosswalks help to create a continuous route network for pedestrians and improve pedestrian visibility by alerting motorists to their potential presence at crossings and intersections. Application of Facility • Should be used at fully-controlled intersections where sidewalks exist (all-way stop signs or traffic lights); • Should not be used at uncontrolled crossings as a stand alone device when speeds exceed 40 mph, to discourage unsafe crossings; and • At uncontrolled crossing locations and where multiple motor vehicle travel lanes per direction are present, Advanced Stop Bars should be considered to address the potential for “hidden threat” crashes. Different types of marked crossings. Image courtesy of The Model Design Manual for Living Streets. Design guidance • Advanced Stop Bars should be considered when multiple motor vehicle travel lanes per direction are present in order to minimize risk of “hidden threat” crashes. • Crossings marked with pavers are discouraged as they can be difficult for those with mobility impairments. • High-visibility marked crossings are preferred because they are easier for motorists to see. • Minimum markings consist of solid white lines between 6-24” in width (MUTCD).

Imprinted thermoplastic crosswalks can be used to provide visible and durable decorative patterns in school zones and downtown areas, and can be used to create community identity and branding. Image courtesy of ennisflint.com. 4 Best Practices for Walking: Median Crossing Island Description Median crossing islands make pedestrian crossings safer and easier by dividing them into two stages so that pedestrians only have to worry about crossing one direction of traffic at a time. Median crossing islands make high-volume roads safer and easier to cross, especially for slower walkers such as children and the elderly who might otherwise get stranded in the middle of the roadway. Space can sometimes be a constraint as crossing islands require the provision of a median in the center of the road. Application of Facility • Multi-lane roads; • Roads where speeds are high or where there are Median crossing island (Bainbridge Island, WA, pictured above). Image courtesy of FHWA. high volumes of traffic; and • Schools, transit hubs, trails, shopping centers and work centers. Design guidance • In addition to signage, trees and low ground cover increase visibility to alert drivers of the presence of the median island; • Minimum width of 6ʼ; • Adequate lighting should be provided; and • Pedestrian path in the median should be angled so the pedestrian faces traffic before crossing. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 5 Best Practices for Walking: Curb Extensions Description Curb extensions are the extension of the sidewalk and curb into the travelway at corners. These features (also known as bump-outs) improve pedestrian safety by increasing the visibility of pedestrians to motorists, by slowing down right-turning motorists, and by reducing crossing distance, thus decreasing the time it takes for a pedestrian to travel across an intersection. Additionally, curb extensions can provide room for street furniture, landscaping or gathering space for pedestrians while waiting to cross the street. Application of Facility • Curb extensions should only be applied where street parking is present; Curb extension and marked crosswalks on Main Street in Downtown Hopkins, MN. • Should never extend into travel lanes, including those designated for cyclists; and • Appropriate for busy collector streets, minor arterials where parking is allowed, in commercial / downtown districts, and in residential districts. Design guidance • Curb extensions are not to interrupt travel lanes, including bike lanes. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 6 Best Practices for Walking: Pedestrian Hybrid Beacon (PHB or HAWK) Description The pedestrian hybrid beacon (PHB or HAWK) is a pedestrian-activated red-indication signal designed for locations where a standard traffic light does not meet traffic engineering warrants. The HAWK gives pedestrians a chance to comfortably cross busy roads at intersections or mid-block locations protected by an enforceable, red-indication signal for motorists. The HAWK remains dark until activated by a pedestrian pressing the crossing button. Once activated, the signal responds immediately with a flashing yellow pattern that changes to a solid red light providing unequivocal “Stop” guidance to motorists. HAWK signals have been shown to elicit very high rates of motorist compliance. Cost for installation of a HAWK typically ranges from $75,000 to $150,000. Pedestrian Hybrid Beacon (PHB, or HAWK) at a crossing of Division Street in St. Cloud. Application of Facility • Where no traffic signal is present; • At mid-block or intersection locations; and • The MUTCD (Chapter 4F) has guidance for applying a HAWK on roads with speeds of more than 35 mph and less than 35 mph based on Pedestrian Per Hour and Vehicle Per Hour approach numbers. Design guidance • Should include installation of a marked crosswalk; and • An advanced stop bar should be installed ahead of the crosswalk. HAWK signal sequence. Image courtesy of Neenah, WI. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 7 Best Practices for Walking: Rectangular Rapid Flash Beacon (RRFB) Description The Rectangular Rapid Flash Beacon (RRFB) is a high-intensity flashing sign assembly that is placed ahead of a crosswalk. It helps alert drives to the presence of the crosswalk. The RRFB is pedestrianactivated, and uses an irregular “stutter” flash pattern with very bright amber lights (similar to those on emergency vehicles) to alert drivers to yield to pedestrians who wish to cross. The RRFB offers a higher level of driver compliance than other flashing yellow beacons, but lower than the HAWK signal. Installation cost typically ranges from $10,000 to $15,000 for two assemblies (for installation on each side of the street). Application of Facility Solar-powered RRFB installation in St. Petersburg, FL. Image courtesy of pedbikeimages.org, Michael Frederick. • RRFBs can be used at crosswalks where no traffic signal is present; • Suitable for two-lane roads (one assembly on each side of the street) and four-lane roads (one assembly on each side of the street and in the median or center island); • Not compatible with three-lane approaches if roadside-mounted signs are used (due to potential line of sight issues / obstruction of signs); • FHWA permits the overhead placement of RRFBs, when it is not possible to achieve clear visibility of roadside signs; for placement, FHWA directs: “Only a minimum of one such sign per approach is required and it should be located over the approximate center of the lanes of the approach or where optimum visibility can be achieved.” Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report Design guidance • Employ RRFBs only at crossing problem areas, school routes, or high volume routes in order to prevent a decrease in compliance; • A beacon should be placed between the pedestrian crossing sign and the attached arrow plaque; and • For overhead signs, no arrow plaque is required. 8 Best Practices for Walking: Countdown Timers Description This device consists of a standard pedestrian crossing signal which works in conjunction with a timer that counts down during the period in which the ʻred handʼ symbol is normally blinking. The timer indicates exactly how much time is left until crossing is no longer permitted. Countdown timers are well understood, are relatively low-cost and easy to install, and effectively reduce the number of pedestrians in the crosswalk at the time of the light change. Pushbuttons can be used to activate countdown timers. Application of Facility • All crossings with sidewalks or shared-use sidepaths. Pedestrian countdown timer at a pedestrian crossing at an intersection. Image courtesy of Bike Walk Lincoln Park. Design guidance • Can be used to upgrade existing standard pedestrian crossing signals at intersections with high traffic volumes or pedestrian populations with need for greater protection such as elderly citizens and school children • Costs range from $300-$800 per installation Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 9 Best Practices for Walking: Pedestrian Pushbuttons Description Pushbuttons are devices that can be installed at crossings to allow pedestrians the ability to actively signal that they wish to cross at a crosswalk location. Pushbuttons serve to activate the pedestrian-specific crossing signal located at the intersection or crossing. When used, pushbuttons should be clearly visible and easily accessible to pedestrians, and should be located at both ends of the crossing. Pushbutton activation should require minimal effort, and should provide feedback to the user to indicate that their request has been received by the signal system. Application of Facility • All crossings with pedestrian-specific crossing control Pushbuttons at Anderson Lakes Parkway and Flying Cloud Drive in Eden Prairie. signals. Design guidance • Place pushbuttons at a mounting height of approximately 3.5 feet, but no more than 4 feet above the sidewalk while being located as close as possible to the curb ramp without reducing the width of the path; and • Include accessible pedestrian signals (APS) provide audible and/or vibro-tactile signals that correspond to the visual crossing signals for visually impaired pedestrians. An online guide to best practices for APS is available here: http://onlinepubs.trb.org/onlinepubs/ nchrp/nchrp_w150.pdf. Recommended placement location of pedestrian pushbutton signals.

Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 10 Best Practices for Walking: Leading Pedestrian Interval Description A Leading Pedestrian Interval (LPI) is a traffic signal programming practice that sets the pedestrian walk sign to occur several seconds before the ʻgreen lightʼ at the parallel street. This gives pedestrians a head start into the intersection so that they are more easily seen when cars begin to move forward. The LPI is typically three to five seconds, and requires only reprogramming of the light sequence with no additional equipment, making it a low-cost solution. Application of Facility • Wide crossings; • Crossings with high pedestrian or vehicle traffic volumes; The Leading Pedestrian Interval allows pedestrians to cross before cars are permitted to proceed. Image courtesy of bikeuptown.org. • School crossings; and • Crossings where elderly citizens are expected. Design guidance • An LPI of 3 seconds has been shown to provide an adequate lead for pedestrians without reducing the green light time significantly. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 11 Choosing the Right Crossing Treatment Many current design manuals and best practices guides offer guidance on when and where to implement pedestrian crossing treatments. A potentially useful reference for Eden Prairie is the 2011 City of Boulder, Colorado Pedestrian Crossing Treatment Installation Guidelines (available online at http://nacto.org/docs/usdg/ boulder_crossing_guidelines_boulder.pdf) Figure 1 from this report (below) presents a flowchart for selecting appropriate crossing treatments for pedestrians based on the specific roadway configuration. Accompanying tables/figures are provided on the two pages that follow. The Eden Prairie Pedestrian and Bicycle Plan offers more guidance on how and when to apply different crossing treatments.

Painted medians can never be considered a refuge for a crossing pedestrian. Similarly, a 4 foot wide raised median next to a left turn lane can only be considered a refuge for pedestrians if the left turning volume is less than 20 vehicles per hour (meaning that in most cases the left turn lane is not occupied while the pedestrian is crossing). 2. A multiple threat lane is defined as a through lane where it is possible for a pedestrian to step out from in front of a stopped vehicle in the adjacent travel lane (either through or turn lane). Treatment Descriptions A Install marked crosswalk with enhanced road-side signs Specific Guidance: Install marked crosswalk with “State Law – Yield to Pedestrian” signs mounted on the side of the roadway with standard (W11–2) advance pedestrian warning signs; use S1–1 signs for School Crossing locations. B Install marked crosswalk with enhanced road-side and in-roadway (bollard mounted) signs Specific Guidance: Install marked crosswalk “State Law – Yield to Pedestrian” signs mounted on the side of the roadway and on in-roadway bollards; use standard (W11–2) advance pedestrian warning signs; use S1–1 signs for School Crossing locations. C Install marked crosswalk with enhanced signs and geometric improvements to increase pedestrian visibility and reduce exposure Specific Guidance: For 2 or 3-lane roadways, install marked crosswalk with “State Law – Yield to Pedestrian” signs mounted on the side of the roadway and on in-roadway bollards or median mounted signs; use standard (W11–2) advance pedestrian warning signs; use S1–1 signs for School Crossing locations. Add neckdowns or median refuge islands to shorten the pedestrian crossing distance and increase pedestrian visibility to motorists. D Install marked crosswalk with enhanced signs, pedestrian activated RRFBs, and geometric improvements to increase pedestrian visibility and reduce exposure Specific Guidance: Install raised median refuge island (unless it is a one-way street or one already exists) to shorted the pedestrian crossing distance and increase pedestrian visibility to motorists. [If a median refuge cannot be constructed on a two-way street, go to Scenario F]. Install marked crosswalk with “State Law – Yield to Pedestrian” signs WITH pedestrian activated RRFBs mounted on the side of the roadway and on median mounted signs; use standard (W11–2) advance pedestrian warning signs; use S1–1 signs for School Crossing locations. Consider adding neckdowns at the crossing if onstreet parking exists on the roadway and storm drain considerations will allow. [Note: If pedestrian volume falls above the RRFB limit line in Figure 2, consider HAWK beacon, pedestrian traffic signal, or grade-separated crossing.] E Do not install marked crosswalk at uncontrolled crossing. Determine if the speed limit can be effectively reduced to 40 mph AND a raised refuge median can be installed. If so, utilize Scenario D criteria above. If this is not possible, or if pedestrian volume falls above the RRFB limit line on Figure 2, consider HAWK beacon, pedestrian traffic signal, or grade-separated crossing. Specific Guidance: Consider HAWK beacon, pedestrian traffic signal or grade-separated crossing; application of these treatments will consider corridor signal progression, existing grades, physical constraints, and other engineering factors. F Do not install marked crosswalk at uncontrolled crossing with 3 or more THROUGH lanes per direction or where the speed limit is ≥ 45 mph and/or there is not a median refuge on a 5-lane crossing. Consider HAWK beacon, pedestrian traffic signal, or grade-separated crossing. Specific Guidance: Consider HAWK beacon, pedestrian traffic signal or grade-separated crossing; application of these treatments will consider corridor signal progression, existing grades, physical constraints, and other engineering factors.

These paths often link parks and other recreation destinations, and some serve broader regional connection purposes. Shared-use paths may exist as sidepaths, paralleling roadways throughout the city and offering off-road space for pedestrians and bicyclists. Shared-use paths are generally comfortable for users of all ages and abilities. Application of Facility • Along corridors where there is a sufficient width of The Minnesota River Bluffs LRT Trail. continuous right-of-way. Design guidance • For shared use paths (off-road trails): - Recommended width of 10 - 12 feet • For sidepaths (shared use paths provided paralleling roadways): - Recommended width of 10 - 12 feet if provided on only one side of the street, and 8 feet if provided on both sides of the street - Must consider interaction of users with intersections and driveways Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 15 Best Practices for Biking: Conventional Bike Lanes Description Bike lanes designate a portion of the roadway for preferential use by bicyclists. Lanes are defined by striping, pavement markings and signage. Bike lanes create separation between cyclists and motorists and increase cyclist comfort and visibility. On some roads, space availability may be a constraint; however, implementing a “road diet” (for example, by converting a four-lane roadway to three-lanes), or decreasing the width of travel lanes (down to 11 ft or 10 ft in urban settings) can often free up additional roadway space and provide a solution to this issue. Application of Facility • Bicycle lanes should be considered for streets that exceed 3,000 or higher motor-vehicle average daily traffic (ADT); and A conventional bicycle lane. Image courtesy of pedbikeimages.org, Jennifer Campos. • Bicycle lanes are not recommended in the following situations (shared-use paths should be used instead): - 2-Lane Road with ADT greater than 10,000 and motor-vehicle speeds of 45 mph or greater; or - 4-Lane Road with ADT greater than 20,000 and motor-vehicle speeds of 45 mph or greater. Design guidance • Provide “Dooring Zone” clearance when bike lanes are located adjacent to parked vehicles; • High frequency of painted markings indicating that the space is a bike lane; • Paved shoulders may be used in-lieu-of bicycle lanes when no curb and gutter is present; • Place pavement markings out of the path of turning vehicles to minimize wear; and • Minimum width recommendation for implementation of on-street bike lanes is 5ʼ wide (outside of curb and gutter). Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 16 Best Practices for Biking: Buffered Bike Lanes Description Buffered bike lanes provide cyclists with extra space between the bike lane and moving traffic, increasing their comfort. Buffers can provide cyclists with adequate room to pass without having to merge into automobile traffic. Application of Facility • All locations where a bike lane is considered; • On streets with higher travel speeds and/or higher travel volumes; • On streets that provide additional lane width; and • Buffered bike lanes may provide a safer and more comfortable designated bicycling space for parents with schoolchildren than conventional bike lanes and should be considered for routes serving school locations. A buffered bike lane. This example has a buffer on the left for separation from moving vehicles and a buffer on the right for separation from parked cars (Park Avenue, Minneapolis, pictured above). Design guidance • Frequent bicycle pavement markings indicating to all road users that the space is designated for cyclists; • Color may be used at the beginning of each block to clearly indicate to motorists that the space is a buffered bike lane; • Buffer is typically marked with 2 solid white lines with optional diagonal hatching of 3ʼ; and • Buffered bike lane example in a constrained space: 3ʼ buffer plus 4ʼ bike lane next to the curb may be considered a 7ʼ bike lane. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 17 Best Practices for Biking: Contraflow Bike Lanes Description Contraflow bike lanes are bike-only lanes traveling in the opposite direction of one-way motor vehicle traffic. Contraflow bike lanes improve bicycle access to destinations, increase connectivity and reduce the need for cyclists to take detours. Additionally, contraflow lanes decrease wrong-way riding and sidewalk riding, which can be a hazard to both the cyclist and pedestrians using the sidewalk. Application of Facility • One-way streets; • Narrow streets; • Lower speed, lower volume streets; and • On corridors where alternative routes would require A contraflow bike lane in Minneapolis. cyclists to make detours. Design guidance • Accompanying signage: Bicycle lane symbol should be used to define the bike lane and direction. A “ONE WAY” sign with “EXCEPT BIKES” should be posted along the facility and at intersections to inform motorists of contraflow treatment; • Separation of contraflow lanes from motor vehicle lane should be shown with a solid double yellow line; and • Contraflow lane width: 5.0ʼ minimum (not including curb and gutter). Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 18 Best Practices for Biking: Advisory Bike Lanes Description An advisory bike lane (also known as a “queuing street”) is a treatment applied to narrow residential or low volume and low speed streets. Advisory lanes allow for two way traffic while still allowing room for two bike lanes. In the instance that two cars meet going opposite directions, a car is allowed to merge into the bike lane with caution. Advisory lanes allow for cyclists to have priority on roadways that would otherwise be too narrow for bike lanes while also encouraging motorists to drive more cautiously. Application of Facility • Corridors with low motor vehicle traffic volumes and speeds; • Narrow two way streets; and • Do not provide centerline separating motor-vehicle Advisory bile lanes on E. 14th Street in Minneapolis. Image courtesy of Star Tribune. traffic lanes. Design guidance • Advisory bike lane width: 5ʼ-6ʼ; • 2-way motor vehicle lane: 12ʼ-18ʼ; and • Colored pavement can be used on the edges of the roadway (in the bike lane area) to indicate to drivers that the space is prioritized for bicycles. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 19 Best Practices for Biking: Cycletracks Description A cycletrack is an exclusive lane for cyclists separated from motor-vehicle traffic by a painted buffer and/or physical barrier (such as a curb, parked cars, or bollards), and separated and distinct from the sidewalk. Different forms of cycletracks include one-way protected cycletracks, raised cycletracks and two-way cycletracks. Cycletracks significantly increase bicycle ridership for people of all ages and experience levels because the significant separation from motorized vehicles greatly increases rider comfort. Cycletracks also increase safety by reducing the likelihood of ʻdooringʼ crashes. Cycletracks require more space and infrastructure than conventional bike lanes, and require special design attention at intersections. Cycletracks are the preferred on-street bicycle accommodation where the right-of-way space allows for its installation. Elements of a one-way protected cycletrack. Application of Facility • Adjacent to roadways with few cross streets and longer blocks; • Major roadways with high motor vehicle speeds and traffic volume; and • Streets with parking lanes. Design guidance • Should be designed with consideration of intersections and driveway crossings; • Colored pavement may be used to further define the bicycle space; and • One-way cycletrack width: 6ʼ to 12ʼ.

Image courtesy of Flickr.com, Joel Mann. 20 Best Practices for Biking: Bicycle Boulevards Description A Bicycle Boulevard (also sometimes known as a Neighborhood Greenway or Neighborhood Slow Street) is a neighborhood residential street modified to calm automobile traffic and discourage cut-through traffic to make walking and bicycling on those streets more comfortable. Application of Facility • Residential streets where traffic calming is desired; • Residential streets a block or two away from a major thoroughfare with high traffic volumes; and • Target speed for motor-vehicle traffic on a bike boulevard should be 20 to 25 mph. A small traffic circle helps keep traffic speeds down along this bike boulevard. Design guidance • Stop signs should be turned to face cross streets to reduce the number of stops for cyclists; • Traffic calming devices (traffic circles, speed tables) will reduce motor vehicle speeds and create a safer environment for cyclists and pedestrians; • Wayfinding markers should be employed to direct cyclists to bicycle boulevards from major thoroughfares and to alert motorists to the presence of cyclists; • Road paint elements should be utilized to designate the roadway and remind motorists to be mindful of bicyclists; and • Signals, roundabouts, and/or median refuges The Riverlake Greenway bike boulevard in Minneapolis. should be used at major intersections when necessary to calm and/or redirect through traffic. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 21 Choosing the Right On-Street Bicycle Facility See Figure 3 for guidance on selecting the appropriate on-street bicycle facility. Many current design manuals and best practices guides offer guidance on when and where to implement bicycle treatments - bikeways, signs, signals, crossings, and markings. The Eden Prairie Pedestrian and Bicycle Plan offers specific guidance on how and when to apply different bicycle treatments. Figure 3a.

Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 22 Best Practices for Biking: Bike Boxes Description A bike box is a designated area for cyclists at the head of an intersection. Pavement markings signal to motorists to stop a greater distance before an intersection, allowing cyclists to move forward and stop in the bike box, increasing their visibility and decreasing the possibility of “right hook” crashes. This treatment also gives cyclists greater priority over motorists by allowing them to be the first to begin movement when a traffic signal turns from red to green (ideally installed with a leading bicycle signal, similar in concept to a Leading Pedestrian Interval). Application of Facility • Signalized intersections with high volumes of bicycles and/or motor vehicles, especially those with frequent bicyclist left-turns and/or motorist right-turns A bicyclist approaching a bike box on the University of Minnesota campus in Minneapolis. Design guidance • Box may be ineffective if it is not properly marked with surface color; • The box may be disregarded by motorists if it is not commonly filled by bicyclists; • Box depth: 10ʼ-16ʼ; • Ingress bike lane should be used to define bicycle space and allow bicycles to bypass stopped motor vehicles; • High-visibility pavement markings and greencolored pavement surfacing should be used; and • “WAIT HERE” marking should be used to guide motorists to stop before the box. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report Bike boxes enhance the visibility of bicyclists and allow them to get out in front of motor vehicles at intersections.

This treatment distinguishes the lane from the rest of the roadway, making cyclists more visible. It is recommended that high-friction surfacing be used over standard paint because it is more slip-resistant and it doesnʼt have to be reapplied as often (standard paint has to be reapplied every year or two). Application of Facility • Within bike lanes and cycletracks; • Corridors with heavy auto and bicycle traffic; • Through busy and/or complex intersections and at “conflict” points, such as driveways; • Use melted thermoplastic treatment with anti-slip Green painted lanes through an intersection on the University of Minnesota campus in Minneapolis. characteristics - has a 7-8 year life expectancy; and • Areas where illegal motor vehicle parking in the bike lane is common. Color Recommendation • PMS 375 Design guidance • Provide appropriate signage to accompany pavement markings; • Use green high-friction surfacing rather than paint; • Consistency in coloring bike facilities is important (Green color is standard in US applications); • Color can be provide in conflict areas alone, or throughout the facility; and • White border lines should be provided along the edges of the colored lane to maintain consistency with other bike facilities.

At this location, motor vehicles travel across the bicycle lane to turn right. 24 Best Practices for Biking: Shared Lane Markings (Sharrows) Description Shared-lane markings (often called sharrows) are pavement markings used to communicate the bicyclistʼs right to use the full roadway space for his or her travel. Sharrows help bicyclists position themselves safely in travel lanes too narrow for a motor vehicle and a bicycle to comfortably travel side by side. Sharrows may be used as an alternative to, or in conjunction with, bicycle boulevards. If ADT is 3,000 or greater, bike lanes or cycletracks should be used instead of sharrows. Application of Facility • Streets with low to moderate motor vehicle traffic volume, and where right-of-way width does not allow a bicycle lane or protected bike facility; A sharrow marking. • If right-of-way width allows room for a bicycle lane on only one side of the street, a sharrow may be utilized in downhill direction; • Can be used to clarify bicyclist movement and positioning in challenging environments such as intersections and at a combined turn/bike lane; • Should be used as a treatment for streets identified as bike boulevards; and • Should not be used for bicycle routes meant for travel by schoolchildren or inexperienced bicyclists. Design guidance • High frequency of markings indicating shared lane environment; • Markings should be placed in the center of travel lanes and out of turning vehiclesʼ paths to minimize wear from automobile treads; • Typical bike-and-chevron symbol dimensions are Sharrows are recommended to be installed with signs signaling that bicycles may use the full lane.

Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 25 Best Practices for Biking: Bicycle Traffic Signals Description Traffic signals for bicycles are electrically powered traffic control devices used to provide guidance to bicyclists at intersections. Bicycle signals are coordinated with motor-vehicle signals to provide a protected crossing to cyclists at an intersection, reducing stress and delays and increasing bicyclist comfort and safety. They also discourage illegal and unsafe crossing maneuvers. Traffic signals for bicycles include: • Bicycle Signal Heads and supplemental “Bicycle Signal” sign, clearly visible to oncoming bicycles (and motorists, if applicable); • Signal detection and actuation; and • Intersection crossing markings. A traffic signal for bicycles in Northeast Minneapolis. Application of Facility • Intersections where high volumes of bicyclists have to travel across roadways with high volumes / high speeds of motor-vehicle traffic. Design guidance • Identify which signal treatment is appropriate by analyzing the factors involved: speed limit, average daily traffic, anticipated bicycle crossing traffic; • Determine a clearance interval appropriate for the specific intersection; and • The bicycle clearance interval should be sufficient to accommodate 85% of bicyclists at their normal travel speed. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 26 Best Practices for Biking: Bicycle Loop Detectors Description Loop detectors detect the presence of bikes on the roadway. Detectors should be installed to cover areas of the road where cyclists are likely to ride, including the right edge of travel lanes and the center of bicycle lanes. Pavement markings can be used to direct cyclists to the proper spot where the signal device may detect their presence. These markings also alert motorists that bicycles will be present in various locations at signalized intersections. Loop detectors are advantageous in that they allow bicyclists to activate traffic control devices without having to find and reach for a button. Diagonal quadrupole pattern. Image courtesy of California DOT. Application of Facility • Busy intersections with traffic control; and • Crossings with traffic signals for bicycles. Design guidance • The best standard design for detecting the presence of bikes is a Type D Loop, also known as a diagonal quadrupole pattern. This loop design is sensitive over its entire width with a quick drop off in sensitivity outside its perimeter, which helps avoid detection of vehicles in adjoining lanes; and • Sensitivity setting for the loop amplifier should be tested and adjusted to ensure that the detector is activated by using only a bicycle wheel. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 27 Best Practices for Biking: Wayfinding Signage Description A bicycle wayfinding system is a comprehensive network of signing and pavement markings indicating destinations along preferred bicycle routes. Wayfinding signage encourages cycling by familiarizing riders with the bicycle network and by making it easier for cyclists to reach preferred destinations. Application of Facility • Bike route intersections; • Along street and bicycle paths; and • At decision points. Wayfinding signage for bicyclists in Washington, D.C. Image courtesy of dc.gov. Design guidance • Should provide information on destination, direction and distance (in miles and in minutes, calculated at speed of 10 mph); • Decision signage indicating the intersection of two or more bikeways should be placed well in advance of all decision points; • A consistent font, such as ClearviewHwy, is recommended for maintaining consistency with other road signs; • Follow MUTCD standards for placement; and • The frequency of way-finding signs is important. Confirmation signs should be placed every 1/4 to 1/2 mile along of street bike routes and every 2 to 3 blocks along on street routes. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report 28 Best Practices for Biking: Bicycle Parking Description Bicycle parking is an end of trip facility that makes it more convenient and inviting for people to arrive by bicycle to a destination. Provision of adequate bicycle parking cannot be overlooked: if bicycle parking spots are inadequate or if finding them is enough of an inconvenience, cyclists will next time choose a different mode for arriving or may choose another destination altogether, even if the provided bicycle routes are perfectly safe and convenient. Application of Facility Bicycle parking conveniently located in a commercial district. • Utilize a style that allows secure locking of the bike (frame and front tire) to the rack without need of lifting the bike. The “Inverted U” and “Post and Loop” style bike racks are preferred; • Locate bicycle parking appropriately with consideration for the rackʼs proximity to the building entrance it serves, its placement along a pathway used by cyclists to approach the building, and its visibility from both the interior and exterior of the building; and • Provide an adequate number of racks to meet the needs of people visiting the area. Additional details Generally, there are three components to bicycle parking: 1) The type or design of the bike rack itself, which supports the bicycle; 2) The location of the rack area, including its relationship to the building entrance it serves and the cyclistsʼ approach to that entrance; and 3) The design of the rack area (the “bike parking lot”), which may include several individual bike racks. Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report Two of the preferred types of bicycle rack: the “Inverted U” (left) and the “Post and Loop” (right). 29 Best Practices for Biking: Bicycle Parking The bike rack The rack should support the bicycle upright by its frame in two places, enabling the frame and one or both wheels to be secured while preventing the bicycle from tipping over. Additionally, it should not require a cyclist to lift their bike to be able to lock it securely - a useful rack design should allow a cyclist to roll-in or back-in their bicycle to lock it. The rack area The rack area is the “bike parking lot” that the racks and the circulation needed to move in and out of the racks define. To be functional and useful, certain minimum clearances and access rules should be observed: • Individual racks should be located no closer than 30 inches to each other in order to allow sufficient space for easy entry and removal of bicycles on either side; • No rack element should be closer than 24 inches to a wall or other obstruction in order to allow full usability and easy access to perimeter racks; • Large rack areas, or rack areas with high turnover, should provide more than one entrance to ease circulation of cyclists and pedestrians; • Rack areas should preferably offer protection from rain and snow in order to ease loading and unloading of bikes and to keep bike saddles dry; and • When multiple rows of bike racks are provided, the circulation space provided from the wheel of a bike on one row to the closest wheel of a bike on the next row should be a minimum of 48 inches. Location of the rack area One of the most important considerations in providing useful and functional bicycle parking is the location of Eden Prairie Pedestrian and Bicycle Infrastructure Toolbox – Final Report Arrangement of a bike parking area with parking for 20 bicycles and a central aisle for circulation. Image courtesy of Dero Bike Racks. the rack area in relation to the building it serves. Some guidelines for locating the rack area include: • The recommended location for a bicycle parking area is immediately adjacent to the entrance it serves, preferably within 50 feet. It should be located as close as possible without blocking the entrance or hindering pedestrian movement to or from the building; • The rack area should be clearly visible from the entrance it serves and from the buildingʼs approach line; • Bike rack areas should be as close or closer than the nearest car parking space; • Buildings with multiple active entrances should include bike rack areas at each entrance; and • Racks that are hard to find, are far from principal entrances, or perceived to be unsafe will not be used by cyclists. 30
