Bus dynamic dispatching system and dispatching method based on wifi detection and GPS positioning

Abstract

The invention discloses a bus dynamic scheduling system and scheduling method based on WiFi detection and GPS positioning. WiFi probes are arranged on the bus and the platform to detect in real time the devices with WiFi functions on the bus and in the vicinity of the platform. Record MAC address data; use vehicle-mounted GPS equipment to record real-time GPS data of buses; use the core algorithm to reduce noise and match MAC address data, estimate the number of passengers in real time on the bus, and the number of people waiting at the platform; set the waiting time for passengers Satisfaction function, setting the satisfaction function of the bus company with the departure frequency as a parameter, and determining the weight of the two according to the actual situation to obtain a comprehensive satisfaction function; based on real-time data such as the real-time number of passengers of the dispatched vehicles and the real-time number of passengers on each platform , to solve the optimal value of the satisfaction function, and dynamically obtain the departure frequency that adapts to the passenger flow of the current line.

Description

technical field [0001] The invention relates to an intelligent bus management system and a management method, in particular to a bus dynamic dispatch system based on WiFi detection and vehicle-mounted GPS positioning, and a dispatch method for bus dynamic dispatch by using the system. Background technique [0002] At present, in most cities in my country, the public transport system is an important part of urban passenger transportation, and it 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. Real-time monitoring and efficient scheduling of public transport vehicles can be realized by obtaining the real-time position and passenger loading situation of...

AI Technical Summary

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
