A Study on Reasonable Size of Urban Bus Stops

Treated as key components of bus stops optimization de-sign,existing researches about the number of parking space and park-ing capacity for bus lines at a bus stop in China still need further study.In light of existing transportation conditions in Wuhan,this paper,through improving queuing theory models,presents the computational method to determine the relation between the number of parking space and parking capacity for bus lines.In the case that following vehicle passing leading vehicle in/out bus stop is permitted and not permitted,the paper respectively calculates the parking capacity for bus lines,based on survey data in Wuhan.The paper concludes with suggestions for bus stops: in former case,no more than 4 parking spaces with park-ing capacity of 17–20 bus lines;while in latter case,no more than 3 parking spaces for common bus stops with 9–11 bus lines,and the sug-gestion for bay-style bus stops is 4 parking spaces and 13–16 bus lines.
