Abstract

The invention discloses a traffic information service method, and belongs to the field of intelligent transportation. The traffic information service method comprises the steps that (1) a primary road network is selected on a navigation electronic map on the basis of the road grade, and dynamic path planning is carried out on the primary road network and a secondary road network; (2) voice guiding is carried out on the primary road network on the basis of dynamic path planning information and a key guiding point; (3) if a user needs to be guided before reaching an entrance of the primary road network and after leaving an exit of the primary road network, dynamic path planning information generated before the user enters the primary road network and after the user leaves the primary road network is provided for the user in a supplementation mode. The invention further discloses a traffic information service system. The traffic information service system comprises a gateway module, a dynamic path planning engine and a primary road network generation module. Due to the fact that the traffic information service method and system achieve expression and application of road condition information in the mode of being independent from the electronic map, abstract road condition information of the urban primary road network is provided, and the path planning service and the light-weight class navigation service, on the basis of road conditions, of the primary road network are provided.

Description

technical field

[0001] The invention relates to the field of intelligent transportation, in particular to a traffic information service method and system. Background technique

[0002] Faced with the deteriorating urban traffic conditions, dynamic traffic information, especially real-time traffic information, has become increasingly in-depth and affects people's lives, providing traffic guidance and travel planning information for public travel, transportation, etc., so as to save time, reduce costs and Low-carbon environmental protection and other purposes. Among them, dynamic route planning and navigation plan the optimal driving route for the user to reach the destination based on real-time road condition information (comprehensive consideration of route mileage, travel time, etc.), and realize TURN-BY-TURN navigation to avoid traffic congestion, which is road condition information Service the most mainstream application method.

[0003] However, in the process of traff...
