Title: Impacts of Port Gate Operations on the Highway System: A Case Study

Abstract: This presentation examines the impact of extended gate operations at the Los Angeles/Long Beach ports on the highway system. Under continued pressure to adjust operations in ways that mitigate traffic and air quality impacts of port operations, and in response to threatened regulatory legislation, terminal operators collaborated to establish and implement a voluntary program of extended gate hours. The program, known as PierPASS, assesses a Traffic Mitigation Fee (TMF) on eligible containers moved into and out of the ports during regular daytime hours. The PierPASS program resulted in a significant temporal shift of cargo moves at the ports. We examine the effects of this shift on heavy truck traffic. Using a traffic simulation model, we estimate PierPASS effects on highway system performance for various weekday time periods. A shift of truck traffic out of daytime and into evening hours has resulted in little change in the level of peak period traffic volume, and hence in the level of congestion, despite significant growth in container volumes since PierPASS was implemented. The presentation concludes with some observations on recent events and the implications of PierPASS for reduction of externalities associated with port related trade.
