This Grant for Rapid Response Research (RAPID) funds the collection of important, perishable data on how risk perceptions after a vivid event that received widespread media coverage 1) influence travelers' selection of transportation mode in the near, medium, and long term; 2) change the tradeoffs transit users are willing to make among safety, speed, frequency of service, cost, and reliability after such an incident; and 3) attenuate or sharpen over time and geographic distance from the accident. This grant allows a small team to collect shifting traveler perception and decision data through three waves of a survey of Metrorail and Park-and-Ride bus commuters. Our hypotheses are that in the aftermath of the accident, changes in risk perceptions over time and space?the amount of time since the June 22nd accident and the distance of commuters from both the accident site and the line on which it occurred?influence mode and route choices, as well as preferences for different characteristics of transit. We will administer a set of choice experiments in each wave to test these hypotheses.To the best of our knowledge, studies of mode choice and system preferences in the aftermath of a major disruptive event do not exist. The data will allow (1) consideration of safety in mode choice models and (2) systematic examination of the attenuation of intense feelings (resulting from the crash) over space and time and their role in decision making. This study also provides attitudinal and preference data in the context of major incidents and allows analysis that policy makers and transit agencies can use to plan appropriate alternative transit-based modes for captive riders. Such planning will help minimize personal economic impacts associated with the event and psychological impacts of temporary loss of connectivity. Furthermore, this research will improve the partnership between social science and engineering.

该快速反应研究基金（RAPID）资助收集重要的易逝数据，这些数据涉及媒体广泛报道的生动事件后的风险感知：1）影响旅行者在近期，中期和长期内对交通方式的选择; 2）改变交通用户愿意在安全，速度，服务频率，成本和可靠性之间做出的权衡。以及3）随着时间和距事故的地理距离而衰减或锐化。 这笔赠款允许一个小团队通过对Metrorail和Park-and-Ride公交车通勤者的三波调查收集不断变化的旅行者感知和决策数据。 我们的假设是，在事故发生后，随着时间和空间的变化，风险的看法？自6月22日事故发生以来的时间，以及事故发生地点和事故发生线路之间的通勤距离？影响模式和路线选择，以及对不同过境特点的偏好。 我们将在每一波中进行一组选择实验来检验这些假设，据我们所知，在重大破坏性事件之后，还没有关于模式选择和系统偏好的研究。 这些数据将允许（1）在模式选择模型中考虑安全性，以及（2）系统地检查强烈感觉（由碰撞引起的）在空间和时间上的衰减及其在决策中的作用。 这项研究还提供了在重大事故的背景下，态度和偏好的数据，并允许分析，决策者和过境机构可以用来规划适当的替代交通为基础的模式，俘虏乘客。 这种规划将有助于最大限度地减少与事件相关的个人经济影响和暂时失去连接的心理影响。 此外，这项研究将改善社会科学和工程学之间的伙伴关系。
