Embodiment Construction

[0033] The system consists of a system center and at least one vehicle-mounted terminal equipped with an electronic map + mobile positioning device. The vehicle-mounted terminal is also equipped with at least a CPU to run the software of the path finding algorithm, an instruction memory to store information of the information collection point, and an electronic voice device to play the steering instructions in the form of route voice to the driver.

[0034] The mobile positioning device can be made by using all existing mobile positioning technologies that can obtain its motion coordinates from a motion carrier.

[0035] At present, satellite positioning systems are widely used, such as the United States GPS, Russian Glonass, my country's Beidou positioning system, and the terminal device of the future Galileo system in Europe.

[0036] In addition, other positioning technologies can also be combined in the positioning device of the vehicle terminal, such as an RFID reading device...

Abstract

The invention proposes a method and system that can automatically collect traffic information, and can also select shortest time line based on current position. The system consists of system center and terminals installed on vehicles. The terminals send to the system center the time and position information when they pass information collection points. The system center send to terminals the average passing time of road segments, thus provide drivers the shortest time line.

Description

Technical field [0001] The invention relates to a traffic information service method and system based on the combination of path travel time and vehicle navigation. Background technique [0002] The wayfinding algorithm technology that uses the vehicle-mounted terminal including electronic map + GPS to perform route navigation and screens the shortest driving route to the destination is well known in the world. This technology has been developed to the extent that when the vehicle leaves the predetermined driving route, it can be based on the vehicle’s Current location, choose a new route to the destination. However, this technology can only perform geographic navigation, and cannot combine traffic information commonly used in urban traffic with geographic navigation to select the best driving route. [0003] Chinese patent 200410045137.5 proposes a method for obtaining the shortest travel time route based on past traffic information, but this method does not involve traffic info...
