The EVIPAS model described is a computer program designed to analyze and optimize a wide range of intersections, phasing, and controller characteristics of an isolated fully actuated traffic signal. It will evaluate almost any phasing combination available in a 2- to 8-phase NEMA type controller and similar phasing structures for a Type 170 controller. The model will provide optimum timing settings for pretimed, semi-actuated, fully actuated, or volume-density control using a variety of measures of effectiveness chosen by the user. A wide range of geometric features, phasing alternatives, and detector layouts can be evaluated. EVIPAS combines a user friendly input module with a multivariate gradient search optimization module and an event-based intersection microsimulation. It has been field-tested and validated and replicates well-observed vehicle and signal behavior. The model is programmed in Fortran 77 and currently can run on VAX 8600 and IBM 3080 mainframes.
