  3. Project Objectives Incident Management intends to improve the Incident Management Process first responders coordination Secondary Congestions project intends to Well define secondary incidents spatially and temporally investigate the full impact of freeway incidents Bayesian Traffic Safety Analyzer development estimates risks of various locations traffic flow and Incident prediction

  4. Methodology • Incident Management • Discrete modeling • Hybrid modeling • Systems properties, safety and liveness, validation • Secondary Congestions • Case studies • Data analysis • Redefining the progression curve for queues due to accidents • Bayesian Traffic Safety Analyzer • Crash data analysis • System modeling • System implementation 4

  5. Anticipated Benefits • Reduce incidents clearance times • Efficiently maximize the use of resources • Better understand nature of incidents and its implications on traffic flow • Development of general models and methodologies that can be used in transportation • Development software tools and applications

  6. LVMPD and NHP Crash Data

  7. Incident Management Modeling • Formal Language and Automata Theory • Finite State Processes (FSP) Models • Labeled Transition Systems (LTS) Diagrams for FSP Models 7
