Problems solved by technology

[0004] After long-term research by the inventor, it has been found that quantitative analysis of communication connectivity in dynamic bus dispatching has not yet been carried out in my country. If the wireless communication connectivity probability of dynamic bus dispatching within a certain area can be calculated, the quantitative analysis can obtain the wireless communication connectivity in the area. It will help to accurately grasp the reliability of the wireless communication connection for the dynamic dispatching of buses in the region, and at the same time provide theoretical support for the scientific and reasonable deployment of public transport information centers and road traffic facilities for the urban public transport infrastructure construction department

Abstract

The invention discloses a communication connectivity analysis method for bus dynamic scheduling under an internet of vehicles environment, and the method is a method for analyzing the intra-area wireless communication connectivity under the situation of bus dynamic scheduling of a vehicle ad hoc networks (VANET). The method comprises steps of firstly determining elements participating in the bus dynamic scheduling under the internet of vehicles environment; determining a communication method adopted among the elements of the bus dynamic scheduling; classifying a communication structure in the bus dynamic scheduling process into a route-vehicle communication system and a vehicle-vehicle communication system so as to analyze the basic structural characteristics of the communication connectivity in the scheduling process; and finally under the limitation of relevant proposal condition, calculating a wireless communication connectivity probability of the bus dynamic scheduling within a given regional range to obtain the connectivity of the intra-area wireless communication.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a communication connectivity analysis method for dynamic bus scheduling in a vehicle networking environment. Background technique [0002] The dynamic bus scheduling in the Internet of Vehicles environment is an automatic scheduling technology based on new communication means, multi-source information acquisition and new scheduling concepts. The dispatching technology uses an ad hoc network specially designed for inter-vehicle communication. It applies ad hoc network technology to inter-vehicle communication, enabling drivers to obtain other vehicles' status information (such as vehicle speed, direction, position, brake pad pressure, etc.) and real-time road conditions. [0003] In the process of bus dynamic scheduling in the Internet of Vehicles environment, when a traffic accident or traffic accident occurs, the bus information center mainly send...
