A control strategy named TOL (Traffic Optimization Logic) based upon the criterion of minimization of traffic operating costs and disturbance of the environment at a given traffic demand was developed. The method calculates at regular intervals, if the prevailing phase should be extended or not, based on short-term predictions of the resulting benefit and disbenefit to the different categories of traffic in the intersection. TOL was tested and compared with conventional fixed-time and vehicle-actuated (VA) control with or without bus priority by means of simulation and field experiments. Another control strategy for isolated intersections is also presented, a phase generating strategy which on-line creates new phases depending on the traffic demand in the intersection.
