Intelligent multi-vehicle bidirectional-track traffic simulation system and method based on Zigbee network

Abstract

The invention discloses an intelligent multi-vehicle bidirectional-track traffic simulation system and method based on the Zigbee network, belonging to the technical field of intelligent traffic. The system comprises vehicles of a proper amount (usually greater than 10), and each vehicle is provided with a Zigbee module, an electromagnetic wire and an RFID card reader; the electromagnetic wire is laid underground to provide bidirectional navigation signals, RFID cards are laid at crossings to indicate turning of the vehicles, and traffic lights are also arranged at the crossings; the vehicles inquire states of the traffic lights at the crossings via infrared receivers, and thus decide driving states in the next step; and a host computer can modify the driving routes of the vehicles in real time. According to the system and method, RFID technology is combined with Zigbee technology, the system and method can be applied to an intelligent traffic system which includes multiple vehicles, bidirectional tracks and traffic lights, the intelligent traffic system is simulated in a more vivid manner, and higher authenticity and practicality are provided.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a multi-vehicle two-way lane intelligent traffic simulation system and method based on a Zigbee network. Background technique [0002] With the rapid increase of vehicle ownership, problems such as traffic congestion, traffic accidents, energy consumption and environmental pollution caused by urban traffic are getting worse day by day. Intelligent Transportation System (ITS, Intelligent Transportation System) has received extensive attention at home and abroad. However, due to the limitation of environment and cost, the research process of ITS system is difficult to carry out and carry out in reality, and it is necessary to use simulation and miniature model to carry out experimental verification and analysis of advanced technology. [0003] The urban micro-traffic simulation system is more flexible and accurate in describing the actual traffic beha...

Problems solved by technology

However, the above-mentioned research platform is mainly a computer-based software platform, which cannot accurately simulate and reproduce the real system, and its motion model seldom considers the factors of the actual environment, such as driving habits, signal lights, intersections, etc. There is a large deviation between the obtained road network simulation and the actual situation
