322 Conchester Highway

More Efficient, Adaptive Traffic Signal Timing

Under the U.S. 322 (Conchester Highway) Improvement Project, PennDOT is adding new, adaptive traffic signals to intersections along the project corridor.

According to the FHWA, poor traffic signal timing contributes to traffic congestion and delay.  Conventional signal systems in place along U.S. 322 (Conchester Highway) and elsewhere use pre-programmed, daily signal timing schedules to trigger traffic signal cycles.  However, adaptive signal control technology adjusts the timing of red, yellow and green lights to accommodate changing traffic patterns and ease traffic congestion.

The main benefits of adaptive signal control technology over conventional signal systems are that it can:

  • Continuously distribute green light time equitably for all traffic movements;
  • Improve travel time reliability by progressively moving vehicles through green lights;
  • Reduce congestion by creating smoother flow; and
  • Prolong the effectiveness of traffic signal timing.

Ridesharing Programs

There are many alternatives to driving alone, including taking transit, ride-sharing, alternative work schedules, working from home, and more. PennDOT and the Delaware Valley Regional Planning Commission (DVRPC) have teamed up to help you find the best way to get to work during construction, and after.  Better commutes mean better work at the office or site! Click here or contact DVRPC’s Office of Commuter Benefits to learn more.

Transportation Management Associations

Our region's transportation management associations (TMAs) are administering components the DVRPC's Mobility Alternatives Program (MAP) that will help employers and employees find creative ways to get to work on time, and back home again.
