Real-time path planning method based on vehicular ad-hoc network

Abstract

The invention discloses a real-time path planning method based on a vehicular ad-hoc network. The technical scheme is characterized in that the method comprises the following steps: 1) obtaining map data and extracting information; 2) collecting real-time traffic information by utilizing the vehicular ad-hoc network technology; 3) setting road weight based on the real-time traffic information and carrying out path finding; and 4) updating the real-time traffic information in the driving process and carrying out path finding again. The real-time path planning method solves the problem that an existing path planning system lacks of real-time performance and accuracy, and provides more convenient and faster driving paths for users to cope with different degrees of road congestion information and ever-changing road traffic states.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted wireless ad hoc networks, in particular to a method for acquiring real-time traffic information and real-time path planning of the vehicle-mounted ad hoc network. Background technique [0002] In recent years, due to the increase in the number of vehicles and the lag in the construction of transportation facilities, traffic safety issues and congestion problems have become increasingly prominent. Intelligent transportation, ease of congestion, and more convenient travel have become the focus of people's attention. In this context, Vehicular Adhoc Network (VANET), as an important part of intelligent transportation, has attracted more and more attention. Vehicle ad hoc network creatively applies ad hoc network technology to vehicle-to-vehicle communication, enabling drivers to obtain other vehicle status information and real-time road condition information within the range beyond the visual...
