Abstract A web-based intercept survey was designed and implemented in order to capture the response of transit riders in the Chicago metropolitan area to a variety of service disruptions. Current transit riders were intercepted in the field from November 2017 through January 2018, according to a sampling plan based on local ridership information, in order to gain a representative sample for analysis. Each participant completed a questionnaire regarding the intercepted trip, along with demographic and travel experience information. The survey included a series of stated-preference responses where the current trip is randomly disrupted and alternative travel modes are proposed with service characteristics randomly altered from a baseline scenario. This was designed to understand individual trade-offs between various mode alternatives and travel plan modification strategies under a variety of scenarios. Altogether, 659 transit riders gave responses to 2626 different disruption scenarios. In general, a plurality of riders (49%) choose to continue using transit, either waiting for service restoration or using agency-provided shuttle service, although at a decreasing rate as the travel delay increases. Fewer riders, approximately 15%, choose to alter their activity patterns altogether, while 26% would alter their travel to use either a taxi or an alternative transportation network company (TNC). Having a more detailed understanding of the behavior of riders under various disruption scenarios should allow transit agencies to better prepare for service recovery and restoration after and during local disruptions.

1 Introduction The Chicago metropolitan area is one of the largest and most dense concentrations of people, industry and commerce in the United States. The Chicago area is also vulnerable to many categories of hazards—these include flooding, tornadoes, blizzards and man-made emergencies. As a transportation hub, it is imperative that the region be prepared to recover quickly from these various hazards. Transportation networks are a critical resource in disaster management and recovery operations. A key component of understanding how transportation authorities can best plan for and manage the transportation system to help the region be ready to respond and recover from emergency situations for many hazards lies in understanding traveler behavior. It is imperative to understand how travelers, specifically transit users, respond
