The transition phase is generally defined as the process of switching from one timing plan to another; this process may include changes in offset, phase split or cycle length until coordination for a new timing plan is reached once again. This paper proposes a non-linear mathematical model to improve the performance of the transition between signal timing plans at coordinated intersections. The model comprises the minimization of a social costs function, which includes a reduction in delay, gas emissions and fuel consumption by considering multiple objectives that embrace more measures of effectiveness. An ant colony algorithm is used to find the optimal parameters of coordination and to determine the time required during transition. Finally, an evaluation of the effectiveness of the new model is realized based on its ability to minimize, delays, and air pollution emissions and fuel consumption. Numerical results show that model proposed is effective method for to reduce social costs associated with transition period.
