Ashbourne Subdivision Access Traffic Analysis
Re:
Ashbourne Subdivision Access Traffic Analysis Memorandum
Introduction
Ashbourne Subdivision is a proposed residential development located on High House Road between NC
55 and Cranborne Lane/ Sir Walker Lane in Cary, NC. A total of 64 single family units are proposed to be
constructed on the north side of High House Road, and up to 25 single-family units on the south side of
High House Road. After discussions with the Town of Cary and NCDOT staff, traffic analyses were
conducted to evaluate the development’s traffic impact on the High House Road corridor and the
proposed right-in/right-out and median U-turn site access. This memo summarizes the traffic analysis
results. Figures and traffic analysis output files are included in Appendix A and Appendix B, respectively.

Site Trip Generation and Distributions
The proposed residential development is expected to generate a total of 847 daily trips, including 67
trips in the AM peak hour and 89 trips in the PM peak hour. Site trips were distributed to the study
network based on traffic counts at the adjacent Cranborne Lane / Sir Walker Lane intersection.

It is noted that the northern development has another access point on NC 55 (at the Wellesley Trade
Lane intersection) through interconnectivity with the adjacent shopping center. Site trips to/from NC 55
likely will use this entrance. Given the overall low site traffic volumes and the projected trip distribution
pattern (primarily to/from the east on High House Rd), the NC 55 access point and its potential trip
assignments were not analyzed in this study. Assuming the High House Road entrance as the only access
point for the northern development would yield more conservative analysis results.
Traffic Impact and Access Analysis
The study area includes five existing intersections on High House Road between NC 55 and Carpenter
Upchurch Road (NC 55, Sir Walker Lane/Cranborne Lane, Widdington Lane, Jenks Carpenter Road, and
Carpenter Upchurch Road), two proposed right-in/right-out site entrances, and two proposed median Uturn openings. Both weekday AM and PM conditions were analyzed for the following scenarios:
2016 Existing Conditions
Recent traffic counts obtained from the Town of Cary were adjusted (assuming a 3% annual growth
factor) to estimate the 2016 traffic volumes. Traffic signal plans and timing schedules were also obtained
from the Town and NCDOT. This analysis evaluates the current intersection operational performance.
2021 Future No Build Conditions
As the construction is expected to commence in late 2016, the future analysis year is 2021 (or five years
from the start of construction) in accordance with the Town’s analysis guidelines. A 3% annual growth
factor was used to estimate the 2021 background traffic volumes. The 2021 No Build traffic volumes also
include trips from approved off-site developments as documented in the “Herndon Property TAR”. In

Ashbourne Subdivision Access Traffic Analysis Memorandum
addition, this analysis takes into account the committed transportation improvement by the proposed
H7 High School – a new 300’ westbound right-turn lane on High House Road at the NC 55 intersection.
2021 Build with Improvements Conditions –Alternative 1 (Median U-Turns Only)
The 2021 Build traffic volumes include both the No-Build volumes and the site trips. In addition to the
proposed median U-turns, this analysis also includes the future Town of Cary/NCDOT transportation
improvements (a new traffic signal at the High House Road /Jenks Carpenter Road intersection, and a
new westbound left-turn lane on High House Road at the Widdington Lane intersection) and the
resulting trip (U-turn traffic) redistributions.
2021 Build with Improvements Conditions –Alternative 2 (Dual WB Left-Turns)
As the NC 55/ High House Road intersection is expected to have significantly higher delays due to the
future background growth and off-site developments, an alternative intersection configuration
(converting the inside westbound through lane to a second westbound left-turn lane via pavement
marking and signal revisions) was also evaluated for the Build with Improvement conditions.
Intersection Capacity Analysis Results
The traffic analysis results are summarized in a table on the following page. Comparing the 2021 No
Build and Build with Improvements Conditions traffic analysis results, the subject development is
expected to cause minimum delay increases at the two existing signalized intersections on High House
Road (NC 55, Carpenter Upchurch Road).
With the proposed median U-turn openings and the new westbound directional left-turn lane at the
Widdington Lane intersection, the U-turn movements at the Cranborne Lane/Sir Walker Lane
intersection are expected to be eliminated or significantly reduced. Traffic simulations, which more
accurately model the gap acceptance behaviors, suggest that the Build with Improvements condition
average delays on the Sir Walker Lane and Cranborne Lane approaches are similar (AM peak) or less than
(PM peak) those in the No Build Conditions.
At the High House Road and Widdington Lane intersection, the new westbound directional left-over is
not expected to cause any noticeable delay increases. The traffic simulations and queue analysis also
suggest that a westbound left-turn lane with 100’ of storage likely will provide adequate storage capacity
(PM max queue length 103’) without negatively affecting the eastbound left-turn operations at the
Carpenter Upchurch Road Intersection.

Ashbourne Subdivision Access Traffic Analysis Memorandum
Ashbourne Subdivision Access Traffic Analysis Memorandum
The new traffic signal at the High House Road / Jenks Carpenter Road intersection will greatly reduce
delays on the northbound Jenks Carpenter Road approach. This intersection is expected to operate at
LOS B during both AM and PM peak hours.
The 2021 No Build analysis shows that, due to the background growth (3% per year) and off-site
developments, the NC 55/ High House Road intersection is expected to operate at LOS E in the AM peak
hour and LOS F in the PM peak hour. During both peak hour conditions, the eastbound Green Level
Church Road approach will have heavy delays and excessive queueing. Converting the inside westbound
through lane to a second exclusive left-turn lane, as shown in the Alternative 2 analysis, along with signal
timing optimizations may improve the intersection operations during both peak hours.
Median U-Turn and Site Access Locations
Based on ten one-hour simulations runs, the westbound left-turn queues (maximum queues) at the NC
55/High House Road intersection may extend 610’ (Alternative 2) to 750’ (Alternative 1) during the PM
peak hour, the worst condition of the day. Given the conservative nature of the traffic analysis (which
accounted for both the 3% annual growth and off-site development trips, assumed only one access point
for the northern development, and did not allow right-turn on red) and the queue length estimates, the
westbound median U-turn may be located approximately 700’ from the NC 55 intersection (measured
from the start of the raised median). A 125’ of storage length should be provided for this U-turn lane
based on the projected traffic conflicts.
The eastbound median U-turn may be located approximately 400’ from the Sir Walker Lane/Cranborne
Lane intersection (measured from the end of the raised median), to provide at least 100’ of separation
from the downstream eastbound left-turn lane (into Sir Walker Lane). A 100’ of storage length should be
provided for this U-turn lane based on the projected traffic conflicts.
The two proposed right-in/right-out site entrances on the current site plan are both located in the
approximate midpoint between the new median U-turn openings (which are 1200’+/- apart), and appear
to provide adequate weaving distances in traffic simulations. There are several factors that may affect
the driveway locations: minimum intersection/driveway spacing, sight distance, and the historic
property on the south side of High House Road. Considering the anticipated speed, acceleration
distance, and stopping sight distance associated with a typical U-turn passenger vehicle, the downstream
right-in/right-out driveway probably should not be located within 200’ from the median U-turn opening.
On the south side of High House Road, to meet the minimum spacing distance and avoid encroaching on
the existing historic property, the driveway likely needs to be located on the east side of the property.

Ashbourne Subdivision Access Traffic Analysis Memorandum
Because of the existing horizontal curve on High House Road and the downstream eastbound U-turn
movements, it is desirable to locate the South Entrance immediately to the east side of the historic
property to maximize the sight distance and weaving distance.
The current North Entrance location, approximately 600’ from either median U-turn openings, appears
to be an acceptable location based on traffic simulation results. This entrance may be shifted to the east,
if deemed necessary, to increase the weaving distance.
Conclusions and Recommendations
Traffic analyses were conducted to evaluate the traffic impact and access design for the proposed
Ashbourne Subdivision. The analysis results indicate that the development will have overall minimum
impact on the existing High House Road corridor, especially with the proposed new traffic signal at the
High House Road /Jenks Carpenter Road intersection and a new westbound left-turn lane at the High
House Road and Widdington Lane intersection (to be implemented by the Town or NCDOT). To mitigate
the traffic congestion caused by the background growth and off-site developments, an alternative
intersection configuration (converting the inside westbound through lane to a second westbound leftturn lane via pavement marking and signal revisions) may be considered in the future for the NC 55/
High House Road intersection.
The median U-turn and site access locations were also evaluated based on traffic simulations and queue
analyses, taking into account the traffic conflicts, minimum spacing distance, sight distance, and the
existing historic property. It is suggested that the westbound U-turn should have 125’ of storage, and
may be located approximately 700’ from the NC 55 intersection (measured from the start of the raised
median). The eastbound median U-turn should have 100’ of storage, and may be located approximately
400’ from the Sir Walker Lane/Cranborne Lane intersection (measured from the end of the raised
median). The South Entrance is recommended to be located immediately to the east side of the historic
property, approximately in the current location. The North Entrance may also remain in the current
location, approximately 600’ from either median U-turn openings. The North Entrance may be shifted to
the east, if deemed necessary, to increase the weaving distance.
The approximate median U-turn and site access locations are suggested based on relatively conservative
traffic analyses and engineering judgement. The final locations may be adjusted for field conditions (e.g.
grades, drainage structures, utilities), and to accommodate the Town and NCDOT’s preferences.

Note:
1. October 2015 TMCs at the High House Rd /NC 55 intersection were grew by 1.5% to estimate the 2016 peak hour volumes.
2. Volume imbalance between this and the next intersection at Sir Walker Ln/Cranborne Ln is assumed to be attributable to the
driveway volumes at the Walmart and Dollar Tree entrances just east of NC 55.
