Embodiment 1

[0041] The invention discloses a traffic navigation system, which includes an information collection module, an information sending module and an information receiving module arranged on the roadside and on the vehicle; the system also includes an emergency traffic incident early warning module, and the early warning module includes an early warning module arranged on the vehicle or on the vehicle. The emergency traffic event early warning unit beside the road; when the emergency traffic event early warning unit detects or receives an emergency traffic event, the priority is set according to the distance between other emergency traffic event early warning units and the emergency traffic event, and the emergency traffic event is prioritized. Send traffic incident information to other emergency traffic incident warning units. Preferably, the traffic emergency early warning unit sends traffic emergency information to other traffic emergency early warning units within 500 meters fr...

Embodiment 2

[0078] In order to better understand the technical solutions of the present invention, further description will be made below in conjunction with the accompanying drawings and the second embodiment. The wireless ad hoc network traffic navigation method based on multivariate data of the present invention is as follows: Figure 4 shown.

[0079] A wireless mobile vehicle network is formed between vehicles on the road. In the wireless mobile vehicle network, on the one hand, the longitude, latitude and speed information of each vehicle is distributed, and on the other hand, various traffic accident information and picture and video information transmitted on demand are distributed. Therefore, each vehicle node calculates the real-time road conditions in the neighborhood, makes different levels of safety processing for different traffic emergencies, obtains dynamic implementation road condition information and corresponding video picture information through the vehicle ad hoc net...

Abstract

The invention discloses a traffic navigation method of a wireless ad hoc network based on multi-source data, including a sudden traffic accident prewarning process. The prewarning process includes the steps: 1, the information collected from an information collecting module is obtained; 2, the emergency degree of the accident and the region and direction where the accident information is required to be issued are all arranged according to the information acquired from the step 1; 3, a vehicle knot which collects the sudden traffic accident information adjusts the priority and issuing region of the information according to the type and emergency degree of the traffic accident and transfers the accident information according to the issuing direction of the information; 4, the vehicles knot which receives the sudden traffic accident information inform drivers and passengers of the prewarning information ahead. The invention additionally adopts the prewarning function for sudden traffic accidents to better avoid the chain collision when the accident happens.

Description

technical field [0001] The invention belongs to the technical field of intelligent information processing, and relates to a traffic navigation method, in particular to a wireless ad hoc network traffic navigation system and method based on multi-source data, which is used for vehicle traffic information service in urban operating environment. Background technique [0002] Traffic problem is a serious problem in megacities. With the development of wireless mobile vehicle technology, a traffic navigation method based on wireless mobile vehicle ad hoc network technology has been proposed, which can provide users with distributed traffic navigation services. Alleviate urban traffic congestion. [0003] For example, the Fleetnet (FleetNet.http: / / www.et2.tu-harburg.de / fleetnet / index.html.2003-5) project carried out in Germany uses Inter-vehicle Communication to improve drivers and passengers Safety and Comfort, VGrid Project (Anda, J., LeBrun, J., Ghosal, D., et al.: VGrid: Vehic...
