16 Observations • About 17% of daily traffic on NC 54 just east of Orange Grove Road enters/exits NC 54 between this location and just west of Old Fayetteville Road. • During the AM peak, only 9%of traffic on NC 54 just east of Orange Grove Road enters/exits NC 54 between this location and just west of Old Fayetteville Road.This is consistent with a higher proportion of longer commuter trips. • For West Main Street daily traffic, about 12%of traffic enters/exits NC 54 between this just west of Old Fayetteville Road and just east of Orange Grove Road. For NC 54 Bypass traffic,this figure is about 11%. • Trips using West Main Street tend to be more local that trips using NC 54 Bypass. TRAVEL DEMAND MODELS The NC 54 West corridor study area spans two regional travel demand models. The portion west of the Alamance County line is represented in the Piedmont Triad Regional Model (PTRM), while the Orange County portion to the east is part of the Triangle Regional model (TRM v6). Growth Forecasts Traffic growth in both models is derived from forecasts of population and employment growth and characteristics, geographically distributed by traffic analysis zone. Figures 10a-10c and 11a-11c depict TRM and PTRM assumptions about the distribution and growth of population and employment relative to the NC 54 West study area and the three travelsheds presented previously. Because population and employment data available for the two models have different base and design years, values were extrapolated to obtain consistent values for 2017 and 2045. Also, dot-density plots were used to more effectively represent the density, magnitude, and distribution of population and employment among traffic analysis zones (TAZs). Note that each dot represents a number of data points (100 persons; 50 jobs). Dots are randomly located within each TAZ, and do not represent specific locations. The socio-economic forecasts in both models were approved and adopted by relevant MPOs and RPOs for use in transportation planning. Consultation with Alamance and Orange County planning staff did not identify any problems with the growth assumed in either the TRM and PTRM. Observations • Development remains sparse along the middle segment of the corridor, due in large part to environmental constraints. • Relative growth is greatest in the western portion of the corridor, both in Alamance County and Mebane, especially along and west of NC 119. Development includes residential, industrial, and commercial, as well as newly-approved high school at the corner of NC 54 and NC 119.
