- Abstract:
- The bus operating characteristics are analyzed at the bus bay using the trajectories depending on the current status of buses. On this basis, a method for calculating the capacity of the bus bay is developed, which considers the queue probability, the dwell time distribution and the waiting time for a gap in the traffic stream at the curb lane. Then, the distribution model of the dwell time is developed using the survey data of Hangzhou city. And the log-normal distribution shows the best fitting performance. The capacities of the bus bay are computed with the Matlab program under different distribution parameters of the dwell time and different traffic volumes at the curb lane. The results show a large range of traffic capacity as the distribution parameters and traffic volumes change. Finally, the proposed model is validated by measurement and simulation, and the average relative errors between the calculated values and the measured and simulated values are 8.78% and 5.28%, respectively.
- 针对目前城市的公交运行现状, 使用时空分布图分析了港湾式公交停靠站的车辆运行特性, 并在此基础上建立了公交停靠站通行能力计算模型, 该模型综合考虑了站点排队概率、停靠时间分布和汇入间隙的等待时间.利用杭州市的调查数据对公交车辆的站点停靠时间进行了分布拟合, 结果表明对数正态分布的拟合效果最优.使用Matlab编程求出了不同停靠时间分布参数和外侧车道流量下的站点通行能力, 结果显示随着分布参数和外侧车道流量的变化, 站点通行能力的变化范围较大.最后, 使用实测和仿真方法对模型进行了验证, 模型计算值与实测数据、仿真数据的平均相对误差分别为8.78%和5.28%.
