NCDOT TIP U-2817, Evans Street/Old Tar Road Traffic Forecasts |
This project began as a capacity analysis exercise to provide analysis using unconventional intersection treatments to handle conflicting movements at two major intersections. The critical intersections on Evans Street at US 264A/NC 43 (Greenville Boulevard) and at SR 1708 (Fire Tower Road) experienced large delays according to previous forecast estimates. Extensive examination of the Greenville Travel Demand Model revealed that the roadway, while experiencing heavy demand in future years, also provided relief to several parallel facilities when improved. As a result, previous forecasts for the project were reviewed and updated using the travel demand model for base, opening, and design years. An alternate method of forecasting traffic using the difference method was introduced. This method provided reasonable results, particularly at locations where traditional growth methods were deemed unreasonable. Subsequent capacity analyses of future conditions of these two intersections will introduce additional intersections (identified as quadrant roadway intersections or median u-turn intersections) where heavy left-turn traffic will be re-routed to improve traffic operations. Output from the Greenville Travel Demand Model, the most recently adopted and fiscally constrained model developed by the NCDOT was used to develop these forecasts. While the forecasts for the project have been approved, the capacity analysis is still under development to address congestion along the corridor.
