Research On The Process Of High-speed Train Crossing Over Railway Lines Based On Cellular Automaton

Rail transport is not only the most important subsystem in traffic and transportation system, but also plays a supporting role in the national economy of our country. With the development of our national economy and further improvement of the gross domestic product, has a great impact on the originally balanced transport market, especially bring hitherto unknown challenge for the railway transportation, the growing demand for higher capacity of railway transportation, and for rail transport speed with the new requirements. Under the background what the requirements of the national strategic shift and railways own development, high-speed railway starts mass construction and put into use. However, the construction of high-speed rail has a certain period, at this stage, China’s high-speed railway has taken segmented construction and segmented into use patterns. The phenomenon what high-speed trains on the existing line running across the line will exist for a long time. It is very important and far-reaching significance to research the impact of high-speed trains to run on the existing line cross section of the existing line.This article launches the research under this background, the main research results obtained as follows:(1)Combing the development course of foreign high-speed railway, analysis of the operating modes and management of foreign high-speed railway, study the foreign development and management to the impact on China’s railway development.(2)Analysis of the existing railway line running across the line of the high-speed train. From the two cases, the train station parking on the existing transfer operation and high-speed trains on the existing stations without parking, are analyzed, respectively, in detail.(3)Analysis of the various modes existing line train control, during the across the line, assuming the train control mode is four-show fixed blocking mode. On this basis, the establishment of a four-show fixed blocking cellular automaton model of opening boundary, the simulation of the process of cross line train.(4)Collecting the data during the simulation; drawing train diagram; calculating the train delay and average speed in different start interval, intermediate station spacing and distance. Study the effects of different conditions on the existing line stopping train during the high-speed railway trains across the line.In this paper, study the process of high-speed railway across line running, some of the results achieved, while there are some aspects not taken into account. For example, high-speed railway trains operating time of Park and Ride, it sharing of passenger will reduce the proportion of buses. This article will follow up in the follow-up study.
