TRAVELER RESPONSE TO RECONSTRUCTION OF PARKWAY EAST (I-376) IN PITTSBURGH
Reconstruction of urban expressways will be required in many metropolitan areas in the next few decades. A summary is presented of traveler responses to a reconstruction project on the Parkway East (I-376) in Pittsburgh, Pennsylvania, which normally serves more than 100,000 daily vehicle trips. Volume counts, vehicle occupancy counts, travel time measurements, and traveler surveys were made before and during the reconstruction. The major responses observed were in route choice and departure times. Large modal diversion did not occur despite ridesharing promotions and train, bus, and park-and-ride lot service improvements. However, a slight measured shift to shared-ride modes may have resulted in significant local benefits for Parkway East travelers during peak periods. Generally, the roadway system in the parkway corridor accommodated a major change in traffic patterns without substantially increased levels of congestion.
