TRANSYT-7F (tm) is a traffic simulation and signal timing optimization program. The primary application of TRANSYT-7F is signal timing design and optimization. TRANSYT-7F features genetic algorithm optimization of cycle length, phasing sequence, splits, and offsets. TRANSYT-7F combines a detailed optimization process (including genetic algorithm, multi-period, and direct CORSIM optimization) with a detailed macroscopic simulation model (including platoon dispersion, queue spillback, and actuated control simulation).

History
TRANSYT-7F is an acronym for TRAffic Network StudY Tool, version 7F. The original TRANSYT model was developed by the Transport Research Laboratory (formerly Transport and Road Research Laboratory) in the United Kingdom. TRANSYT, version 7 was "Americanized" for the Federal Highway Administration (FHWA); thus the "7F." The TRANSYT-7F program and the original TRANSYT-7F manual were developed for the Federal Highway Administration (FHWA) under the National Signal Timing Optimization Project (NSTOP) by the University of Florida Transportation Research Center (TRC). TRANSYT-7F continues to undergo further development, and is currently maintained by the University of Florida's McTrans Center.
