Transportation systems are constantly changing, both in terms of their physical and operational characteristics. As such, it can be challenging to reason about when and where incidents, such as vehicular crashes may occur. However, better intelligence on the evolving risks in a transportation system can assist emergency responders with anticipating where needs are likely to arise so that resources can be tasked more efficiently. This presentation details the development of a spatio-temporal decision support system (DSS) for addressing such a need for state highway patrols in the United States (U.S.). In particular, special focus is given to elements of the system’s design such as the coupling and handling of real-time sources, analytics, as well as field deployment of the DSS. Further, the tuning of the underlying models, integration of feedback from law enforcement officers as well as overall system performance and use is described.
