Draft Comprehensive Transportation Plan Update_September 25

DRAFT

TRANSPORTATION The transportation network within and around Morrisville is primarily oriented to serve automobile travel. Several major roadways, detailed in Table , serve the Town including I-40, I-540, and the Triangle Expressway (NC 147 and NC 540) to the north; Davis Drive to the west and NC 54 to the east, which bisects the Town from north to south; and several east-west corridors including McCrimmon Parkway, Airport Boulevard, Morrisville-Carpenter Road, Aviation Parkway, Morrisville Parkway, and NW Cary Parkway. The rapid development of residential subdivisions without investment in major roadway projects has yielded a disconnected street network and stresses the Town’s major corridors. Roadways within the Town are owned and maintained by either NCDOT, the Town of Morrisville, or private entities such as neighborhood associations. NCDOT maintains the following roads within the Town of Morrisville:

· Airport Boulevard · Aviation Parkway

· McCrimmon Parkway · Morrisville Carpenter Road · Morrisville Parkway · NC 54 (Chapel Hill Road) · NC 540 · Old Maynard Road · Slater Road · Sorrell Grove Church Road · Watkins Road (partial) · Wilson Road

· Cary Parkway · Church Street · Davis Drive · Evans Road

· Holly Creek Road · Jerusalem Drive · Kit Creek Road · Lichtin Boulevard (partial) · Louis Stephens Road

While the Town’s walking and bicycling network has seen significant growth and many opportunities for increased access to transit exist, Morrisville’s growth patterns and commuting trends continue to present significant challenges for the Town of Morrisville to overcome when considering how best to maintain and improve its transportation network. Motor Vehicle Volumes NCDOT collects traffic volume data on state-maintained roadways every other year and develops estimates called average annual daily traffic volumes (AADTs) which represent two-way traffic volumes on an average weekday. The most recent segment level AADTs for the state-maintained roadways in Morrisville are from 2013 and are shown in Table 2-5 and Figure 2-16. NCDOT traffic volume data is not available for the roadway segments without color, and traffic volume data at the segment level is not yet been made available. Figure 2-16 also shows the percentage of traffic consisting of single-unit or trailer trucks. Modeled Traffic Congestion Sophisticated models can simulate the interaction of estimated demand and available supply at a regional scale. The Triangle Regional Model comprises both the Raleigh urbanized area and the Durham-Chapel Hill urbanized area. For the purposes of this Existing Conditions Summary, current congestion levels are derived from the Triangle Regional Model 2010 Base Year Model and are symbolized in Figure 2-17 based on volume-to-capacity ratios. The model represents the roadway network and traffic volumes as they were in 2010 and does not necessarily reflect the impact of intersections and railroad crossings on traffic congestion. Actual congestion near these locations may be greater than what is shown in the travel demand model. However, modeled traffic congestion provides systems-level insight into overall congestion issues and can indicate corridors that warrant higher levels of study and analysis.
