Abstract

The state-of-the-art computer models TRANSYT-7F, MAXBAND, and PASSER-II for arterial signal timing are evaluated considering their capabilities in developing optimal timing plans, input data requirements, and output options. These models were applied on an 11-signal arterial to optimize various combinations of the signal control variables for two-phase and multiphase signal operation. It was found that the timings from TRANSYT-7F were better in terms of traffic performance than the settings from the bandwidth models, under fixed phasing. The settings from MAXBAND and PASSER-II produced very similar results. A number of experiments were also performed to investigate ways for concurrent use of the programs to further improve signal timing. The results indicated that the optimization capabilities of TRANSYT-7F can be improved if the input cycle length and sequence of phases have been optimized with the other models. Suggestions are made for improving the optimization capabilities and the practical application of the selected models.
