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.

这项研究是建立在最近的NSF资助的探索性研究（SGER）项目（NSF奖CMMI 0753580），旨在收集易腐的旅行行为和交通数据后，在明尼阿波利斯的密西西比河上的I-35 W大桥倒塌。该项目的目标是分析收集的数据，并为旅行行为模型奠定坚实的基础，该模型可以回答以下三个开放性问题：1）旅行者如何在网络中断的日常环境中做出旅行决策？2)交通模式是如何从非均衡状态向均衡状态演化的？3)在交通均衡过程中，交通部门应如何优先分配交通资源以应对网络中断？解决这些问题将使交通科学向前迈出一大步，因为由于数据的可用性，在严重的网络中断后，很少研究旅行者的学习过程和由此产生的行为改变。 这项工作将使许多观众受益，包括本科生和研究生，交通研究人员和实践工程师。研究结果将用于提高本科和研究生水平的交通工程课程。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分享。PI将与地方和州交通机构密切合作，并将尽最大努力将本研究的结果传达给交通机构和学术界。
