Study On The Setting Of Bus Stop Considering Road Capacity

Give priority to development of public transport has become the main measure of our country to solve the city traffic congestion,public transportation vehicles need to complete pick up passenger at the bus stop,as an important part of city infrastructure and public transport systems,bus stops widely distributed in the city road network.With the continuous development of public transport,increasing the number of bus stops and bus lines,bus stop setting is not reasonable,which has become increasingly prominent in the bus stops near the queuing time increase,the vehicle operation chaos,which serious interference on the social vehicle’s normal operation,reduce road traffic efficiency.Based on the above background,this paper studies the domestic and international research status and the influence factors of bus stop setting,and focuses on the bus stop setting.This article first summarizes the existing bus stop setting types,put forward the main research object stops are curbside bus stops and bus bay stops,and analyzed two stops characteristics,from the perspective of lane number,road traffic,construction costs and other factors analyzed the bus stop setting conditions.Then the influences stages of bus stops on the road capacity can be divided into move in stop,dwell,and move out stop.Considering the bus arrival distribution of Poisson at curbside bus stops and the queuing overflow probability of buses at the bus bay stops,the delay time models are established.Based on probability theory,queuing theory and gap theory,the reduction model of bus stops on the road capacity are proposed.Finally,through the analysis of the Changchun six bus stop of actual investigation and data,the calibration model of bus stop time,deceleration time,overflow probability parameters,and the accuracy of the model and simulation test by VISSIM.At last,this paper studies the setting conditions of bus stop by using delay model,so as to provide reference for urban road planning and bus stop.
