Signal Optimization Problem with Pedestrians Non-complying at a Single Intersection
Without persons specially assigned to manage pedestrians, pedestrians almost are reluctant to wait in developing cities, such as Xipsilaan during green phases for vehicles. Thus, some vehicles may conflict with pedestrianspsila noncompliance, and be delayed. To solve the signal optimization problem of urban traffic with pedestrianspsila noncompliance, a hybrid optimization algorithm is developed. In this algorithm, the performance index (PI), concerned on the total retained vehicles over the whole control period, includes the number of retained vehicles for waiting green signal and violating pedestrians. The number of retained vehicles for pedestrians violating is estimated by a Monte Carlo method. The simulations are conducted under the condition of heavy traffic demands. The results indicate that, under the condition of heavy traffic flow, this method is more available to protect the pedestrians than the traditional method.
