214 Figure 2 is from the 2013 Annual Average Daily Traffic (AADT) map generated by the Traffic Survey Group of the North Carolina Department of Transportation ( NCDOT). The existing traffic counts are shown in red at the locations where they were measured. US 70 has an average of 5,900 vehicles per day at the intersection with Frazier Road, and Lebanon has an average of 1,700 vehicles per day at its intersection with Frazier Road. Further to the west, just past the intersection with SR 1346, Saddle Club Road, Lebanon has an average of 3,200 vehicles per day. A review of the NCDOT AADT maps for the period 2008 -2013 shows similar traffic counts at these locations. The data indicates approximately a 1% increase in traffic count per year over the past five years. NCDOT has not published ADT data for Frazier Road. Lebanon Road dead -ends to the east of Frazier Road. As a result, it is likely that the majority of the 1,700 vehicles per day reported by NCDOT on Lebanon Road originate to /from Frazier Road and represent traffic to /from US 70 using Frazier as a connector to access points west on Lebanon and connecting to Mill Creek, SR 1345, and Saddle Club Road, SR 1346. Frazier is a well- maintained nominally 20' EP -EP asphalt surface road. The speed limit on the road varies from 35 -45 MPH and the ADT capacity is similar to Lebanon and Efland Road, SR 1004, and well in excess of 3,000 vehicles per day. TRAFFIC IMPACT ANALYSIS The trip generation data for Hart's Mill development was prepared using the Institute of Traffic Engineers 8th Edition Trip Generation Model with OTISS software. The Hart's Mill development was modeled as a land use code 230 Residential Condominium /Townhouse project in keeping with the ownership plan A graph of the underlying average week day ITE TGM data for Residential Condominium Townhouse type is shown in Figure 3. As discussed previously, although recent traffic studies available through the internet show that the traffic generation from co- housing communities is much less than conventional residential development that land use code is not currently available through ITE. As a result, it is believed that the Residential Condominium /Townhouse land use trip generation model provides an upper limit on trip generation from Hart's Mill which, over time, will be proven to have over - estimated the actual traffic generated from the project. The weekday peak hourly AM, peak hourly PM and average trips predicted by the model for Hart's Mill are shown in Figures 4, 5 and 6 respectively. It is projected that most of the traffic out of Hart's Mill will be south bound with a left -hand turn onto Frazier, and most of the traffic into Hart's Mill will be north -bound on Frazier with a right - turn into Hart's Mill.
