BRIDGE: Behavioral Response to the I-35W Disruption: Gauging Equilibration

这项研究建立在最近由美国国家科学基金会资助的探索研究小额赠款项目(美国国家科学基金会奖CMMI 0753580)的基础上，该项目旨在收集明尼阿波利斯密西西比河I-35W大桥坍塌后易腐烂的出行行为和交通数据。该项目的目标是分析收集到的数据，并为建立能够回答以下三个公开问题的出行行为模型奠定坚实的基础：1)在网络中断的情况下，出行者如何在日常环境中做出出行选择？2)交通模式如何从不平衡状态演变到均衡状态？3)交通机构应该如何优先分配交通资源以应对网络中断，特别是在交通平衡的过程中？回答这些问题将是交通科学的一次重大飞跃，因为由于数据的可用性，旅行者在严重网络中断后的学习过程和由此产生的行为变化很少被研究。这项工作将使许多受众受益，包括本科生和研究生、交通研究人员和执业工程师。这项研究的成果将用于提高运输工程的本科生和研究生水平。从该项目和其他相关项目收集的其他数据将与感兴趣的研究人员共享。PIS将与地方和州交通机构密切合作，并将尽最大努力将这项研究的结果传达给交通机构和学术界。

This research is built upon a recent NSF-funded Small Grant for Exploratory Research (SGER) project (NSF Award CMMI 0753580) that aims to collect perishable travel behavior and traffic data after the collapse of I-35W Bridge over the Mississippi River in Minneapolis. The goal of this project is to analyze the collected data and develop a firm foundation for travel behavior models that can answer the following three open questions: 1) How do travelers make their trip-making choices in a day-to-day context under network disruption? 2) How do traffic patterns evolve from a disequilibrium state toward an equilibrium state? 3) How should transportation agencies prioritize the allocation of transportation resources in response to the network disruption, particularly during the process of traffic equilibration? Answering these questions will make a major leap forward in transportation science because the learning process and resulting altered behavior of travelers after severe network disruption has rarely been studied due to data availability. This work will benefit many audiences, including undergraduate and graduate students, transportation researchers and practicing engineers. Results from the research will be used to enhance both undergraduate and graduate level courses in transportation engineering. Additional data collected from this project and other related projects will be shared with interested researchers. The PIs will work closely with local and state transportation agencies and will make their best effort to convey the findings from this research to the transportation agencies and academic community.
