Research On Rationality Of Passenger Flow Lines In Subway Transfer Station Based On Social Force Model

Track with large volume, speed, security, punctuality, environmental protection, energy conservation and land thrifty characteristics, has become one of the main ways to solve city traffic problems. The transfer station in rail transit network is the very important node, and the design for passengers flow lines in transfer stations is a key factor in relation to the transfer station functions to be achieved. Therefore it is necessary to research the rationality of the passenger flows lines in transfer stations and to analyze the level of both subway operating units effectiveness and passenger service quality, and thus make the necessary improvements and optimization, so that the transfer station to the passenger line settings tend to improve.This paper conducted the following research work done in three areas:1.Parameter calibration and validation of the social force model. Social force model is one of the most effective micro-simulation models of pedestrian, and simulation software Anylogic core algorithm is the social force model. In the paper Social force model parameters were calibrated and validated, So that the rationality of passenger flow lines can be analyzed by simulation software Anylogic.2.Specific settings of Passenger flow lines in subway transfer station. The main contents include three aspects:analyze the accordance between passenger flow lines and passenger traffic or the accordance between passenger flow lines and subway train traffic organization(train interval time), determine the size of the flow line facility according to long-term traffic forecasts predict traffic, and set the passenger flow lines.3.Analyze and evaluate rationality passenger flow lines. Define the connotation of the rationality of passenger flow lines, establish specific indicators, propose optimization measures, and compare the two programs.In the final part of the paper, the rationality of the passenger flow lines in Tianfu Square subway transfer station was analyzed.
