TRANSYT 7F (4) uses a mesoscopic-deterministic model for analyzing and optimizing
signal timings on arterials and networks. TRANSYT 7F uses a combination of exhaustive, hill climbing,
and GA-based optimization methods. Furthermore, it uses a delay-based traffic model.
In other words, it is primarily designed to select signal timings that produce minimum system
delay and stops. In addition, it provides a capability to select several secondary objectives,
including minimization of stops and maximization of progression opportunities. During its
optimization process, TRANSYT 7F generates second-by-second flow profiles of vehicles on all
links in the network. Then, it analyzes these profiles to determine MOEs.
