In this Open-Ended Agreement, TPD develops Safety Improvement Plans, including elements of road diets along various corridors. The region of focus for these studies is PennDOT District 6-0, which includes the Delaware Valley counties of Chester, Montgomery, Philadelphia, Bucks and Delaware.
Existing Conditions on Marshall Road and Lansdowne Avenue
The following two projects have been generated from this on-call agreement, for which TPD is currently working on.
Marshall Road Corridor Safety Improvements
This location was identified by the District as one with a high percentage of angle crashes, as well as a moderate percentage of fixed-object/run-off-road and rear-end crashes. The corridor is characterized by a high percentage of fatal and injury crashes. The implementation of safety countermeasures will reduce these types of conflicts and improve the overall safety of the corridor. The treatments proposed as part of this project include converting partial limits of Marshall Road from an undivided four-lane section to a three-lane section including a two-way-left-turn lane, adding exclusive left-turn lanes at intersections, adding exclusive right-turn lanes at intersections, modifying left-turn signal phasing, increasing pavement friction on roadway segments and intersection approaches, interconnecting signals with fiber optic and providing remote communication accessibility along the corridor from PennDOT District 6-0 Regional Transportation Management Center.
Lansdowne Avenue Corridor Safety Improvements
This location was identified by the District as one with a high percentage of angle and rear-end crashes, and consequently one with a high percentage of fatal and injury crashes. The implementation of safety countermeasures will reduce these types of conflicts and improve the overall safety of the corridor. The treatments proposed as part of this project include converting partial limits of Lansdowne Avenue from an undivided four-lane section to a three-lane section, adding two-way left turn lane to two-lane road, adding exclusive left-turn lanes at intersections, modifying left-turn signal phasing, installing dynamic warning flashers, interconnecting signals with fiber optic and providing remote communication accessibility along corridor from PennDOT District 6-0 Regional Transportation Management Center.
