• Abstract:
  From fender-benders to more serious incidents, crashes are the primary source of nonrecurring congestion on Florida roadways. Vehicles that stop or slow down because of a crash not only block traffic flow, they can also cause secondary crashes, further complicating the crash scene and increasing congestion. Predicting when a secondary crash might occur is critical for devising strategies to prevent or mitigate them. However, this is difficult to do. It is not always clear when a crash is secondary, and a useful definition is needed to identify relevant incidents to begin the process of discovering contributing factors. With the increasing availability of real-time traffic measurement, an understanding of these factors could be used to estimate the likelihood of secondary crashes in real time and create new possibilities to reduce these crashes.
