The problem of the conventional signal control system is response delay to the traffic flow changes. In order to solve it, a next generation signal control algorithm named RONDO (ROlling-horizoN based Dynamic Optimization of signal control) has been developed that enables dynamic optimization of signal control parameters according to traffic flow changes. A rolling-horizon algorithm is selected as an optimization method. RONDO can apply to diverse traffic conditions from under-saturated to over-saturated. RONDO also considers reducing traffic accidents. Some simulation tests have been executed for the first step of evaluation of the system. Simulation experiments results show that the system can manage unstable traffic flow well. It also shows the possible application of the system. The system will be installed in 2000. (A*)
