| The intersection is a node connecting roads and coordinating the evacuation of motor vehicle traffic.The location of the nearby bus stops is closely related to the operation of the intersection.Improper layout of the site is affected.The capacity of the site is affected and it is easy to form congestion Delay.This paper mainly studies the optimal setting of bus stops near the intersection.According to different classification methods,the bus stops are classified,and the characteristics of the different bus stops are compared and analyzed.Based on the microanalysis of the inbound and outbound operations of the bus vehicles and the parking process,through the study and reference of traffic flow on traffic,The knowledge and methods of statistical modeling have analyzed and verified that the arrival time distribution characteristics of bus vehicles obey the Poisson distribution.Based on this premise,the traffic capacity of different types of bus stop stations near the intersection is modeled,and the corresponding station examples are selected.Carry out simulation analysis to verify the theoretical model;on the basis of the analysis of vehicle parking characteristics of bus stops near plane intersections and the impact of different types of bus stops,the minimum vehicle delays including bus actual stop delays caused by bus stops are taken as The optimization goal was carried out at the same time through graphic analysis and mathematical theoretical proof,with the goal of minimizing delay,a station optimization model based on vehicle delay was established,and the optimal setting of the bus stop near the upper level intersection was determined.Station location.Select the Xiaozhai East Road-Cuihua Road intersection at Xi’an History Museum and the bus stops distributed within 150 m nearby for investigation,use the proposed optimization model to calculate and analyze and improve the site optimization,and then use VISSIM simulation software to simulate Before and after optimization,the vehicle delays are compared,and the effectiveness of the site optimization model proposed in this paper is verified,which provides a more scientific and reasonable method for the optimal setting of urban conventional bus stops. |
