Subway station passenger flow line optimization and dynamic guidance sign system and design method

Abstract

The invention discloses a subway station passenger flow line optimization and dynamic guidance sign system and a design method, and relates to the field of subway passenger flow evacuation. The system comprises a passenger identification and positioning unit, a passenger congestion degree-based random user balanced passenger flow distribution unit, and an in-station passenger real-time position display and path recommendation unit. The design method comprises the following steps: extracting pictures of all positions in a subway station through in-station monitoring equipment; extracting passenger positions in the picture by using image processing to obtain a passenger distribution condition in the whole subway station; obtaining an optimized passenger flow distribution result based on a random user balanced passenger flow distribution model of the passenger congestion degree; and displaying the real-time distribution condition of the passenger flow and the optimized recommended path on a dynamic guide sign in the station. The invention not only can be used for recommending routes of in-station activities such as entry, exit, transfer and gate selection of passengers in the subway station in a normal operation mode, but also can realize a recommendation function of evacuation routes in the escape process of the passengers in emergencies.

Description

technical field [0001] The invention belongs to the field of subway passenger flow evacuation, and in particular relates to a passenger flow streamline optimization and dynamic guidance sign system and design method in a subway station. Background technique [0002] The subway has the advantages of large transportation capacity, low energy consumption, less pollution and convenient ride, and is playing an increasingly significant role in urban public transportation services. With the rapid development of the subway, the network pattern of the subway line has gradually formed, and the passenger flow has continued to grow. The subway has gradually become one of the preferred modes of travel for people. [0003] At present, the internal structure of the subway station is complicated, and the passenger flow in the station is large. Especially in the morning and evening peak hours, the passenger flow capacity in the station is low, and it is easy to cause blockage at the bottlen...
