Design Guide Line For Beiren Station In Subway Line One During Construction

The subway can ease the traffic pressure in the city to a large extent, but the subway construction period were the "dark period of city traffic". Shijiazhuang is currently in the subway construction period, the construction enclosure brings great pressure to the city traffic of Shijiazhuang. In order to alleviate the traffic pressure in the subway construction period, for the traffic guide plan during subway construction this paper selected beiren intersection to optimize and design which were the representative urban core commercial district located in Shijiazhuang.At first, this article collected the beiren station engineering data; designed traffic volume questionnaire, speed questionnaire and vehicle delay questionnaire; used manual counting method in the investigation of traffic volume, radar velocity measurement method in the investigation of site speed, point sample method in the investigation of vehicle delays. Analysed beiren station traffic situation and found defects and different through the collected survey data, guided for design paves the way for the North Station. And then took the intersection channel, the intersection signal timing optimization, the improvement of public service facilities and Bus Guide scheme, the management of pedestrian and non motorized vehicles, the prohibition of indiscriminate parking, the increase of the number of lanes and traffic diversion measures to design traffic guide scheme for beiren station intersection of the second phase construction block.Used the VISSIM simulation software to simulate traffic navigation scheme, got on a vehicle delay data as the evaluation plan quality parameters, in order to ensure the accuracy of the obtained parameters, genetic algorithm were used to driving behavior parameters of the simulation software for re calibration; then imitation programs really, modify the program, simulation, revise again until you get the parameters meet the requirements of the service level of the road. Designed and optimized the guide line scheme of this intersection from three to six by the same method.This paper designed and optimized the guide line scheme during the construction of Shijiazhuang City Subway No.1 line beiren station based on the guide line design, and used simulation software to guide the design scheme of the test, the theory and practice closely combined together, for Shijiazhuang metro construction block scheme put forward feasible suggestions, but also provide reference for other similar construction.
