This research identified the opportunities to implement ramp management strategies on freeways in Pennsylvania. The research explored the need to integrate local arterial traffic signal systems with ramp management strategies to reduce the impacts of ramp management on local roadways. The report recommends a definition of freeway congestion and screening criteria for candidate ramp management freeways in Pennsylvania. In addition, a case study was performed for the I-376 tunnel bottleneck in the City of Pittsburgh to identify potential ramp management strategies, their impact on local roadways, mitigation strategies for local traffic signal systems and the relative benefits and costs of implementing such a project on I-376. Transportation planning and simulation models were used to evaluate travel pattern changes and measures of performance of the I-376 freeway with ramp management strategies in place.
