Adaptive Traffic Signals to Begin Going Live in Cumberland, Dauphin Counties
Adaptive Traffic Signals to Begin Going Live in Cumberland, Dauphin Counties
HARRISBURG, PA - January 26, 2016 – The Pennsylvania Department of Transportation announced today that the final phases of the InSync Adaptive Traffic Signal Systems will go into operation over the next several weeks on major traffic corridors in Cumberland and Dauphin counties. The adaptive signal technology will function at 27 intersections in Cumberland County and 26 intersections in Dauphin County.
Beginning today, traffic signals along U.S. 11 in Camp Hill from the intersection with Country Club Road down to the ramp area for U.S. 15/581, as well as Market Street at 32nd and 34th streets, will go live, one intersection at a time. The remainder of the Cumberland County work will continue in February on Market Street west through Hampden Township to the intersection of U.S. 11 and Route 114 in Silver Spring Township, as well as Route 114 at Sporting Green Drive and Bent Creek Boulevard.
Over the course of the next month, signals will also go live beginning in Lower Paxton Township on U.S. 22 from the intersection of Allentown Boulevard and Shannon Drive through Susquehanna Township and Penbrook Borough, including a section of State Street in the City of Harrisburg.
Adaptive traffic signals adjust the timing of the green phases to accommodate changing traffic volumes and patterns along specific corridors to ease traffic congestion. PennDOT cautions that motorists may not notice a significant reduction in congestion during peak travel times (morning and evening rush hours). The only viable way to reduce that congestion would be to build additional lanes, which is not a feasible option.
Work on the adaptive signals is being completed by Bruce-Merrilees Electric Company of New Castle, PA, at a cost of $3.6 million. The project is 100 percent federally funded with Congestion Mitigation/Air Quality funds. The signals are expected to be fully functional by the end of February 2016.
