Transportation Studies & Applications

I-95 Corridor Study

This project is being conducted to support rehabilitation and renewal of the Pennsylvania I-95 corridor. Traffic forecasts were prepared to support the redesign of the Girard Avenue, Allegheny Avenue, Betsy Ross Bridge, Bridge Street, and Princeton/Cottman interchanges. Preferred alternatives have been selected for each of these, and construction activities are ongoing. DVRPC is also preparing traffic forecasts to assist with the designation of detour routes during construction phases that will require long-term closures of on or off-ramps. Please go to for a complete overview of the project.

Wawa to West Chester Regional Rail Extension – Ridership Forecast

This project forecasts the number of trips that would result from an extension of SEPTA's Elwyn line from the planned Wawa Station to the Borough of West Chester with three intermediate stations. It compares year 2035 forecasts under a no-build scenario, an electrified extension alternative (one-seat ride), and a diesel extension alternative (requiring a transfer at Wawa). This study does not examine capital and operating costs, station location and design, or operational details.

US 422 River Crossing Traffic Study

The US 422 River Crossing Traffic Study provides daily and peak hour traffic forecasts to support planning and design efforts along the limited-access US 422 Expressway in the King of Prussia area. This portion of the Expressway, which was constructed in the 1980s, is the most heavily-traveled portion of US 422. Daily traffic volumes range from over 60,000 to nearly 100,000 vehicles per day between the PA 29 interchange in Upper Providence Township and US 202 along the Chester and Montgomery county line. This area of US 422 experiences extensive, recurring congestion and significant dealy during both the morning and afternoon peak periods, impacting local commuters, regional traffic, and visitors to the nearby Valley Forge National Historical Park. There are several operational deficiencies, including short weaving areas, limited storage capacity, and inadequate acceleration lane lengths in the corridor. Additionally, several aging bridges, including the US 422 bridge over the Schuylkill River require rehabilitation or replacement. A description of the alternatives under consideration and their traffic impacts is available here.

SEPTA Fare Sensitivity Analysis Using DVRPC's Regional Travel Forecasting Model

This study assesses the ability of the Delaware Valley Regional Planning Commission (DVRPC) regional travel forecasting model to predict the effect that fare increases have on ridership. The study analyzes five scenarios, comparing the model's results to empirical data from other similar studies and to actual observed data from recent fare changes implemented by the Southeastern Pennsylvania Transportation Authority (SEPTA). It also forecasts the projected impact that the introduction of New Payment Technology will have on ridership. This study will allow SEPTA to assess the effects of proposed fare policy changes and to plan future fare system improvements. It will also provide valuable insights into the performance of the current model. This information will be used by DVRPC's engineers and planners to improve the model—to make it more accurate to fare changes, and to enable the model to produce more accurate forecasts.

Long-Range Plan Modeling

DVRPC's long-range land use and transportation plan provides a vision of the region's future and serves as the blueprint for future transportation facilities and services. A regional land use and open space plan identifies appropriate areas for future growth and infrastructure and an inter-connected system of natural resource areas targeted for protection. Forecasts of future population and employment inform the plan and regional indicators track progress toward its goals.

VISSIM Micro-Simulation of Transit Signal Priority (TSP) for PA 3, West Chester Pike

The purpose of this project was first to develop a set of best practices to improve transit service in the West Chester Pike corridor as well as its integration with corridor development; and second to use VISSIM micro-simulation to test the impacts of various operational improvement strategies on the speed and running times of SEPTA Route 104 buses.
