Description

Technical Field

[0001] The invention relates to the technical field of urban rail operation management, and in particular to a subway car riding guidance method and system. Background Art

[0002] Urban rail transit is an important part of the public transportation system in urban infrastructure. However, during peak travel hours, some rail transit lines are overcrowded, which seriously affects the quality of rail transit travel services. In crowded carriages, a common phenomenon is that the middle is loose and the two ends are crowded, and the passenger flow is unevenly distributed. After boarding the train, passengers are accustomed to standing at the entrance and exit, making it difficult for subsequent passengers to board the train, which can easily induce conflicts among passengers in the carriage and accidents such as being stuck in the door and falling on the platform. Therefore, it is necessary to guide the uniform distribution of passengers in the carriage.

[0003] At present, the guidance of passenger flow distribution in urban rail train carriages is mainly based on passenger flow induction based on passenger flow density, that is, the degree of congestion is displayed on electronic display screens inside and outside the carriages to guide passengers to move to relatively relaxed areas. This measure mainly focuses on the passengers' demand for riding comfort, but pays less attention to the passengers' health and safety travel needs. As a result, some short-distance passengers still choose to squeeze in the entrance and exit area with the idea of ​​"squeezing at the entrance and exit for easy getting off", which also causes subsequent passengers to be passively squeezed in the entrance and exit area. Therefore, a ride guidance method is urgently needed to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art. Based on the correlation between passenger flow density and environmental quality in the carriage and the congestion of the carriage entrance and exit and the risk of platform door accidents, a subway carriage riding guidance method and system are provided. The train carriage is divided into multiple area units, and environmental quality sensors are arranged in each area unit to sense the PM of each area unit in the carriage in real time. 2.5 、PM 10 , CO 2 , temperature, humidity and other environmental parameters. Then, the environmental quality index of each area of ​​the carriage is dynamically displayed in the form of a heat map on the display screens inside and outside the carriage to guide the passengers in the carriage to be evenly distributed, especially not to crowd at the entrance and exit areas, and at the same time guide the passengers outside the carriage to choose a suitable carriage location to wait for the train, thereby improving the quality of rail travel services.
