Book excerpt: Planned special events such as sporting events and festivals draw large crowds and limit the capacity of a transportation network built for daily traffic. To alleviate some of the transportation challenges, local and state governments generally adopt a broad range of special event traffic management strategies to improve transportation options, operations, and mobility. In Montana, traffic management practices have typically been done on a case-by-case basis and have not been documented for adaptation and use by other communities. The Montana Department of Transportation (MDT) initiated this project to document existing special event management practices in Montana, to identify the best management practices used in other states, and to provide MDT and local governments with recommendations for improving traffic management strategies. The project consisted of three principal tasks: a literature review, an assessment of MDT's current practices (including meetings, surveys, and interviews with MDT personnel), and a survey of local stakeholders (city staff and event organizers) regarding their practices and experiences managing special events.
