Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like image 3 As shown, the dynamic traffic information service system of vehicle-road coordination establishes a channel for data exchange between vehicle-mounted terminals ("vehicles") and traffic information ("road"). Vehicle GPS information can be used to update traffic information in real time. Information can serve vehicles driving on the road, thus forming a good interaction between "vehicle" and "road". The vehicle-mounted terminal performs two-way interaction with the system through the wireless gateway.

[0025] Among them, when the vehicle-mounted terminal needs to obtain traffic information, it first uploads its own GPS information. After receiving the GPS information, the wireless gateway forwards the GPS information to the traffic information...

Abstract

The invention discloses a method and a system used for providing the dynamic traffic information service and belongs to the intelligent transportation field. The system comprises a wireless gateway, a real-time traffic information database, a global position system (GPS) receiving module, a floating car data (FCD) processing module, a traffic information partial update module, a traffic information issuing module and a traffic information inquiry module. The method comprises the steps of receiving GPS information uploaded by a vehicle terminal, completing update of real-time traffic information, and sending real-time traffic information of road sections relevant to the position of a vehicle to the vehicle terminal according to the GPS information. According to the method and the system used for providing the dynamic traffic information service, a data exchanging channel between the vehicle terminal and the traffic information is built, the GPS information of the vehicle can be used for the real-time update of the traffic information, the traffic information serves the vehicle traveling on the road, and therefore good interaction between the vehicle and the road is achieved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for providing dynamic traffic information services through vehicle-road coordination. Background technique [0002] In the field of intelligent transportation, real-time dynamic traffic information services can provide efficient and feasible traffic guidance and travel planning information for public travel, transportation, etc., so as to save time, reduce costs, and low-carbon environmental protection. Floating Car Data (FCD) technology is one of the technical means to obtain real-time road traffic information in intelligent transportation systems. It uses positioning technology, wireless communication technology and information processing technology to realize the collection of traffic parameters such as GPS position information, instantaneous driving speed and direction of vehicles on the road, and combines the urban road network data to map the collected tra...
