INCISIM is a computer program that simulates the occurrence of highway incidents, the dispatching of emergency vehicles, and the traffic flow on the network. INCISIM can represent multiple types of emergency vehicles, include highway patrol cars, freeway service patrol trucks, tow trucks operating from fixed bases, highway maintenance vehicles, and fire trucks. Incidents are represented by type classifications (corresponding to computer-aided-dispatch codes) and profiles (defining duration and magnitude of incidents). Delay is calculated as a function of these variables, along with traffic flows and highway capacities. INCISIM produces a complete log of incidents that occurred during the simulation along with statistics on highway delays.
