106662 | I-76 Integrated Corridor Management (Upper Merion Township, Lower Merion Township & West Conshohocken Borough, Montgomery County)

This project will provide for the active management of transportation and demand by providing operational improvements on I-76 and supporting arterials between the PA Turnpike and the US 1 interchanges with a series of measures that will allow for the ability to dynamically manage recurrent congestion based on prevailing and predicted traffic conditions through the following:
•Installation of systems and devices for variable speed limits and queue detection-- Speeds will be dynamically changed based on road, traffic and weather conditions. Warning signs will be used to dynamically display alerts to drivers that congestion and queues are present. The limits for this work are as follows: PA Turnpike to US 1.
•Dynamic lane assignments, shoulder, and junction control improvements-- The shoulders will be dynamically controlled along with travel lanes for opening/closing on a temporary basis in response to increasing congestion or incidents. This work includes reconstruction of shoulders up to current standard width and depth for part time shoulder use, and may necessitate increasing pavement or bridge deck width where insufficient, and lengthening of overhead bridge spans as required. Bridge and roadway drainage and storm water management will be improved as required. It is expected that part time shoulder use will be provided on I-76 in both eastbound and westbound directions from the PA Turnpike to I – 476, and on I-76 westbound from US 1 to Belmont Avenue as it relates to Junction controls for I-76 WB from City Avenue (US 1).
•Adaptive ramp metering will be used to dynamically adjust signals at the ramp entrances to proactively manage vehicle flow from access roads. The Limits are from the PA Turnpike to US 1.
•Installation of systems and devices for continuous monitoring of the transportation network, whether by video or other detectors, to aid in traffic incident management coordination and primary /secondary crash reduction, throughput increases, reducing speed differential in traffic flow and increasing trip reliability. The Limits are PA Turnpike to US 1 and it includes US 202, US 422 and US 1 and access roads.
•Installation of a responsive traffic signal system to be coordinated real time with the Regional Transportation Management Center. This should include the traffic signal system network in the proximity of I-76. Arterial signals will be coordinated with ramp metering. Transit signal priority included where applicable. Installation of communications network as required. The limits include Ridge Pike and PA 23 (Conshohocken to US1) .
•Enhanced coordination of operations with SEPTA on bus or regional rail that is parallel to the I-76 corridor including dynamic messaging on DMS to motorists of available parking / travel times of alternate mode and travel availability .
