Abstract TRANSYT is a widely-used traffic model developed in Great Britain. Its purpose is to study the traffic behavior of, and to optimize the signal timings of, a network of coordinated signalized intersections. An important subroutine of TRANSYT is an iterative minimization search procedure based on the so-called “hill climbing” strategy. It attempts to minimize a performance index (a weighted combination of stops and delay) by varying the phase lengths and offsets of each signal. The purpose of this paper is to explain how another search procedure, a modification of Fibonacci search, can be used in place of the hill climbing procedure. This results in a significant improvement in TRANSYT, both in terms of the performance index and computational time.
