摘要: 为了提高公交停靠站通行能力计算方法的精确性,针对目前城市的公交运行现状,使用时空分布图分析了公交车在直线式停靠站的服务过程,在此基础上,综合考虑停靠站排队概率和停靠时间分布,推导了公交停靠站通行能力计算模型.对杭州市公交车停靠时间的分布函数进行了拟合,对数正态分布的拟合程度最优, 2个交通时段的K-S检验值分别为0.083 9和0.050 6.用MATLAB编程得到不同分布参数下的通行能力结果表明:随着停靠时间对数平均值μ的增加,不同泊位数停靠站的通行能力减少了44.4%~47.3%;通过VISSIM仿真得到了停靠站的通行能力,模型计算值与仿真结果的平均误差为6.5%.Abstract: In order to improve the precision of calculation of bus stop capacity, the servicing process of buses at on-line stops was analyzed using the bus trajectories according to metropolitan bus operation status. On this basis, a method for computing on-line bus stop capacity was developed taking into account both the queue probability and the dwell time distribution. Then, the dwell time distribution function was fitted to the field-observed data of Hangzhou city; Kolmogorov-Smirnov (K-S) test shows that the log-normal distribution has the best goodness of fit, with the K-S value of two traffic periods being 0.083 9 and 0.050 6, respectively.The capacities of three kinds of bus stops were computed by MATLAB programming with different parameters of dwell time distribution. The results indicate that the capacity of bus stop with different berths decreases from 44.4% to 47.3% as the natural logarithmic mean of the dwell time μ increases. In addition, the capacity of bus stops was obtained by simulation using VISSIM software. The average relative error between the calculated and simulated results is 6.5%.
