Abstract:
In order to measure the congestion and level of service of regional road networks after traffic diversion for freeway reconstruction quantitatively, the corresponding of traffic diversion and traffic diversion model with real-time feedback is proposed with overall saturation level as the constrict and optimal diversion performance as optimization function. Taking the reconstruction project of Tongguan-Baoji freeway as an example, two diversion programs are compared. This proposed method considered the loading level of traffic volume of diversion segments using the ratio of diversed traffic volume and capacity as the weights so as to describe the congestion condition of diversed regional road network. The analysis result shows it can reach the optimal diversion performance through this method and yield diversion balance. Based on the comparison of two diversion plans(large sized vehicle and small sized vehicle), the result indicates that the sections of saturation in the car-traffic diversion plan is lower than that in the large vehicle-traffic diversion plan. 4 tabs, 1 fig, 8 refs.
