A method of subway passenger service based on real-time information

Abstract

The invention relates to a real-time information-based metro passenger service system. Mobile terminal equipment automatically connects wireless sensors in a metro station and in metro compartments so as to perform data interaction with the servers to acquire relevant information in the metro station in real time, and the relevant information is used for passengers to view in real time; moreover, a heuristic search strategy based on the estimated arrival time of a metro, running time between stations, the current passenger flow information of the metro station and passenger flow information in each metro compartment is proposed, and therefore the optimal proposed ride scheme is obtained, and meanwhile, a time-optimal and distance-optimal scheme is obtained for the passengers to select; after the scheme is determined, according to the position conditions of the current passengers, a prompt of the next route is provided in real time; the passenger flow conditions of the compartments are determined according to the information of the wireless servers of the metro which is about to arrive, and the best waiting position proposal can be given by the system; after the passenger ride, prompt contents, including the time that the metro is about to arrive the next station, the get-off station and the get-off time of the passengers are given in real time, the exit scheme of the metro station and corresponding map information, can be given in real time.

Description

technical field [0001] The invention relates to wireless communication, heuristic search technology and real-time information push service, and is a subway passenger service method based on wireless network real-time information. The present invention aims at the special environmental characteristics of the subway, and obtains real-time information by connecting with a wireless server for wireless communication; for the problem of the optimal ride plan, a heuristic search strategy based on the subway travel time and passenger flow is proposed; After the plan, passengers will be reminded of relevant information by means of real-time push to mobile devices. Background technique [0002] With the rapid expansion of urban population leading to traffic overload, the construction of urban subways has greatly alleviated urban traffic problems. However, due to the increasing number of subway stations and the exponential growth of subway exits at the same time, the guidance maps prov...

Problems solved by technology

However, GPS takes a long time to locate the receiver for the first time, and the positioning process must ensure that the GPS device can receive signals from multiple satellites at the same time

Therefore, in the case of indoor or geographical environment with occlusion, GPS works poorly, especially for the subway station environment, it is difficult for GSP equipment to receive satellite signals (Li B., Quader I., Dempster A., ​​On outdoorpositioning with Wi-Fi, Journal of Global Positioning Systems, 2008, pp.18-26)

[0004] In addition, with the increase in the number of people taking the subway, the flow of people at the station has a great impact on the efficiency and convenience of passengers taking the subway. However, the current subway line navigation software only considers the absolute distance of the route, and does not consider the waiting time and the flow of people at the station.
