System and method of bus dynamic scheduling based on WiFi detection and GPS positioning

Abstract

The present invention discloses a system and a method of bus dynamic scheduling based on WiFi detection and GPS positioning. WiFi probes are arranged on buses and bus stations to detect devices opening a WiFi function on the buses and in a detection range near the bus stations and record MAC address data; vehicle GPS devices are employed to record bus real-time GPS data; a core algorithm is employed to perform noise reduction and matching of the MAC address data and estimate real-time passenger capacities of the buses and the number of waiting passengers at the bus stations in real time; passenger waiting time is taken as parameters to set a waiting satisfaction degree function, departure frequencies are taken as parameters to set a bus company satisfaction degree function, and two weightvalues are determined according to actual conditions to obtain a comprehensive satisfaction degree function; and an optimal value of the satisfaction degree function is solved based on the real-time data such as the real-time passenger capacities of departed buses and the real-time number of waiting passengers at each bus station, and a departure frequency suitable for a current line passenger flow condition is dynamically obtained.

Description

technical field [0001] The present invention relates to an intelligent public transport management system and a management method, in particular to a bus dynamic dispatching system based on WiFi detection and vehicle-mounted GPS positioning, and to a dispatching method for dynamic bus dispatching using the system. Background technique [0002] At present, in most cities in our country, the public transport system is an important part of urban passenger transport, which plays a very important role in the optimization of the operation of the public transport system and the development of the city. The intelligent bus dispatching system comprehensively uses related technologies in many fields such as global positioning system (GPS), geographic information system (GIS), computer, control system, sensor, data design, wireless communication, etc. The real-time location and passenger status of the bus can be obtained through processing and processing, so as to realize real-time mon...

Problems solved by technology

[0003] At present, most of the bus dispatching methods adopt the dispatching method of optimizing the fixed departure frequency obtained from historical data, or the dispatching method of obtaining a quasi-dynamic plan by means of forecasting, but these dispatching methods fail to propose how to use real-time data to optimize dispatching , did not propose parameters such as the frequency of departure that are most suitable for the passenger flow of the current period; in the dynamic bus dispatching technology based on Wi-Fi detection and vehicle-mounted GPS positioning proposed by this technology, the vehicle-mounted and station Wi-Fi detection data and vehicle-mounted GPS are effectively used Data, proposes a method to obtain the real-time passenger status of the bus and the real-time number of passengers on the platform, and proposes how to use these effective data to obtain the optimal bus departure frequency that adapts to the current passenger flow situation
