Vehicular Traffic Flow Dispersion Prediction of Coordinated Signal Control Based on Support Vector Regression

Signal control can reduce traffic delay and improve traffic safety. But when the vehicle meets with red light, it must stop at intersection to wait green light. Coordinated signal control can improve the continuity of vehicular traffic flow movement and reduce delay. Coordinated signal setting is based on platoon dispersion prediction. Thus, improving prediction accuracy can obtain significant benefit for signal coordination. The paper bases on support vector regression to predict platoon dispersion and compares prediction accuracy with Robertson formula.
