[Abstract]:As an important node in the public transport system, the rationality of bus stop design not only has an important impact on the operation efficiency and service level of public transport. Moreover, it also has an important influence on the capacity and service level of urban road traffic. The area of bus stop reflects the definition of the research scope of bus stop. An important parameter in the design of bus stop is the area length of the stop. Unreasonable design of the regional length of the stop will lead to the decline of the capacity of the stop and increase the delay of the stop. On the basis of analyzing the calculation method of the length of the bus stop area, comparing the applicable range, characteristics and limitation of different methods, the paper studies the length and number of the bus stop area under the condition of single berth and multi-berth, respectively. The relationship between maximum capacity. Based on Markov chain, the average queue length model of bus stop is established. During the rush hour, the arrival of the vehicle meets the Poisson distribution, and the regional length of the stop is determined based on the Markov model of the regional length of the stop. The VISSIM simulation software is used to simulate the typical bus stop to verify the feasibility and rationality of Markov model in determining the length of the stop area. Then, through the statistical results of the average queue length, the maximum queue length and the delay of the public transport vehicle, the optimal scheme is 43.62m port station with the area length of 43.62m. Optimize the existing docking area length.
