| 摘要: |
| 为探讨拥堵收费策略的改善效果，从出行者的综合成本出发, 构建适用于拥堵收费的路阻函数和Logit交通分配模型，探讨拥堵收费下交通出行在路网上的重新分配.并以南京市应天大街高架为例设置了拥堵收费虚拟方案，应用路阻函数和交通分配模型进行分析后得出拥堵收费在交通出行量分布、出行分担率、道路服务水平和行程速度上的改善效果.结果表明:拥堵收费能有效引导交通出行的重新分布，提高路网总体通行效率和服务水平，可以认为拥堵收费对交通的改善具有一定效果，但改善效果和拥堵收费费率不是线性正比关系，本次虚拟收费方案下收费费率为5元/次时可取得最佳改善效果.

| Abstract: |
| To improve effects of congestion pricing, an impedance function and a traffic assignment model were introduced to explore the traffic redistribution on road network. Yingtian Street in Nanjing city was selected as the virtual charged fee example. The index differences of trip distribution, travel mode split rate, service level and travel speed pre-and-post implementing the pricing measure were used for evaluation. The results show congestion pricing could effectively lead the traffic into redistribution, and improve the traffic efficiency and service level of the network, which point out the valid effect of congestion pricing on traffic improvement. However, the results also show the improvement is not in directly proportional to the charging rate, and could get the best improvement effect when the rate is 5 yuan per time in this virtual pricing measure.
