Embodiment Construction

[0061] The present invention will be further described below in conjunction with embodiment.

[0062] ginseng figure 1 , a system for predicting and preventing urban traffic congestion, comprising a vehicle navigation device 1, and a traffic information center 2, the traffic information center 2 exchanges data with the vehicle navigation devices of all vehicles in the area through a wireless network 3, the traffic information center 2 communicates with the meteorological , earthquakes, tsunamis, geological disasters, road-related projects, and traffic police information systems are networked to obtain road condition information. The time interval sends the following data to the vehicle navigation device 1:

[0063] a, area number,

[0064] b. One-way road sections with abnormal road conditions in this driving area:

[0065] 1. Section ID,

[0066] 2. Abnormal types (divided into: a congestion, b slippery road surface, c water accumulation, d fog, e snow, f icing, g earthqu...

Abstract

The invention discloses an urban traffic congestion prediction and prevention system comprising a vehicle-mounted navigation device, a wireless network and a traffic information center. The traffic information center is connected with a meteorological station and traffic police information center via the internet to obtain road condition information and also sends road condition data to a vehicle.The vehicle-mounted navigation device plans a driving path based on the received road condition information and sends the driving path and own vehicle information to the traffic information center. The traffic information center calculates road sections that may have congestion during follow-up periods based on the received vehicle information and the driving path, sends congestion prediction information to the vehicle, and sends out instructions of planning paths again to some vehicles that will pass the congested road sections. The vehicle-mounted navigation device makes a new path plan fordriving based on the new path and sends the new path to the traffic information center; and the traffic information center calculates all paths again and sends congestion prediction information and apath re-planning instruction to the vehicle. On the basis of the repeated adjustment, the prediction congestion rates of all road sections can be reduced.

Description

technical field [0001] The invention relates to a system for predicting and preventing urban traffic jams, in particular to a traffic management information system for realizing prediction, forecast and prevention of traffic jams by means of wireless networks and performing cloud computing on big data. Background technique [0002] The existing traffic information system uses a static electronic map, and the vehicle does not know the real-time changes in the road conditions while driving, resulting in inaccurate navigation decisions, and it is impossible to predict the road congestion situation after a period of time, and it is impossible to avoid the occurrence of congestion. Contents of the invention [0003] In order to solve the above problems, the present invention aims to provide a traffic jam prediction and prevention system. [0004] The object of the present invention is achieved by the following technical means. [0005] The present invention is a system for pre...
