摘要

旧金山湾区收费桥梁是横跨九县旧金山湾区的主要交通纽带。这些桥梁经历了极度的拥堵,在高峰时段成为瓶颈,在收费广场长时间排队。广泛采用称为FasTrak的电子收费系统,是确保收费广场车辆通行的一项解决方案。然而,与该国其他收费系统相比,FasTrak系统自成立以来的使用率较低。我们利用预测、营销和运营研究模型提出建议,并与交通部门合作,在高峰时段(上午5点至10点和下午3点至晚上7点)增加FasTrak的使用,作为解决交通拥堵的一种方式。在实施了这些建议之后,FasTrak的使用率从2006年的40%增加到2016年的70%的长期目标。提出了挑战的综合和FasTrak战略计划的实施。此外,对计量经济模型进行了估计,这些模型捕捉了通过拥堵收费实现的FasTrak使用量增加对交通量的影响。我们估计,由于节省了旅行时间,每年的生产力收益约为5.69亿美元。我们的研究有助于理解有效的交通政策在减少拥堵和提高生产力方面的作用。

Adoption of FasTrak on San Francisco Bay Area Bridges: Impact of OR Models in Relieving Congestion
Bay Area toll bridges are the main transportation link across the nine-county San Francisco Bay Area. These bridges experience extreme congestion and become bottlenecks during peak hours, with long backups at the toll plazas. A solution to ensure vehicle throughput at toll plazas is widespread adoption of the electronic toll collection system called FasTrak. However, the FasTrak System has experienced low usage rates since its inception relative to other toll collections systems in the country. We utilized forecasting, marketing, and operations research models to make recommendations and collaborate with transportation authorities to increase FasTrak usage during peak hours (5 am to 10 am and 3 pm to 7 pm) as a way of addressing traffic congestion. After implementing these recommendations, FasTrak usage increased from 40% in 2006 to the long-term target of 70% by 2016. A synthesis of the challenges and the implementation of the FasTrak strategic plan is presented. Further, econometric models that capture the effect on traffic volumes of increased FasTrak usage achieved through congestion pricing are estimated. We estimate productivity gains of approximately $569 million per year due to savings in travel time. Our research contributes to an understanding of the role of effective transportation policies in reducing congestion and improving productivity.
