Method for Computing On-Line Bus Stop Capacity
摘要
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-Smimov (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%.关键词
