Layout Optimization of Guidance Signs in Subway Station Based on Passenger Flow Line

Abstract

With the continuous acceleration of urbanization, urban public traffic congestion is becoming more and more serious. In order to alleviate traffic congestion, people’s demand for public transportation is increasing. Due to the increasing passenger flow in the subway station, the original guidance signs in the station often fail to play the expected role, and passengers cannot get effective guidance in the crowded passenger flow. This paper takes the maximum amount of information obtained by passengers as the objective function to establish the guidance sign layout model, and chooses a 0-1 integer programming model to solve it. Based on the distribution coefficient ρij; , the passenger flow wij; , the weight coefficient d and the inverse of the number of intersections qij , these four variables are used to comprehensively analyze the amount of guidance information of the guidance signs, and set constraints based on the number of passenger flow lines and guidance signs. Xiyuan Subway station, for example, through the site of the actual passenger flow survey, to obtain the required parameters, and finally using MATLAB programming solution, to get an effective guidance sign layout position, improve the guidance sign guide efficiency.
