| 摘 要： | 提出一种城市道路落客区车辆延误的计算模型。分析了独立落客区和路段落客区的交通组织模式。将“排队落客”模式的落客过程分为2个阶段,结合排队论和可插车间隙理论,建立了落客车辆的延误模型,并设计了优化算法。随后以北京市安贞医院入口路段为测试对象,应用VISSIM仿真软件和实际调查的数据对模型进行验证。分析了落客率和落客区长度对落客车辆延误的影响。结果表明,模型能够精准的获取落客车辆的延误,同时可以为落客区的合理设置提供依据。

| Abstract: | A model for calculating the delay of the drop-off vehicles at urban road drop-off area is proposed. The traffic organization modes of the independent drop-off area and the road drop-off area are analysed. The “queue up to drop off” mode process is divided into two stages, a delay model of drop-off vehicle based on queuing theory and gap theory is established, and an optimization algorithm is presented. Taking the entrance section of Anzhen Hospital in Beijing as the test object, the model is tested by VISSIM simulation software and real survey data. The influence of drop-off rate and drop-off area length on vehicles delay is analyzed. The results show that the model can predict the traffic state of the drop-off area and the drop-off vehicle delay accurately, which provides a more reliable basis for the optimal settings of urban road drop-off area. |
