Existing signal timing optimization methods deal with the objectives of minimizing vehicle delay and stops, or maximizing green bandwidths. These objective functions are incorporated in the widely-used computer signal timing optimization programs such as TRANSYT-7F, SIGOP-III, PASSER-II, and MAXBAND. However, signal timings developed from these programs do not guarantee minimum fuel consumption since minimizing fuel consumption is not the ultimate objective of these programs. This study presents a new signal timing optimization model that assures the minimization of vehicle fuel consumption on signalized arterial roadways. A theoretical model that describes fuel consumption in terms of signal timing parameters is developed. The computational algorithms of the model parameters are described. A method of estimating fuel consumption rates of the vehicle fleet on roadways is presented. A computer model for minimizing fuel consumption as a function of cycle length, green intervals, cruise speed, and offsets is developed. An application of the computer model to develop optimum signal timing plans for a signalized arterial highway is presented.
