About the Seminar

In this seminar, Gary Davis will report on the use of data collected in the Strategic Highway Research Program 2 to support microscopic modeling of crashes and near-crashes. In this project, several crashes between a following and leading vehicle were reconstructed using vehicle-based data from a 100-car study, site-based video data from the Minnesota Traffic Observatory, and site-based Doppler shift data from the Cooperative Intersection Collision Avoidance Systems (CICAS) project.

In each case, estimates of acceleration histories, driver reaction time, and the situation at the start of the reaction phase were obtained. The project also demonstrated the potential of systems such as CICAS to provide data on near-crashes in intersections.
