Road traffic path guide method and system and road traffic information service platform

Abstract

The invention discloses a road traffic path guide method and system and a road traffic information service platform. The method comprises the steps: obtaining the predetermination request information and traffic flow information of a navigation path; presetting a proper navigation path according to the predetermination request information and traffic flow information, and generating a navigation path predetermination result; feeding the navigation path predetermination result back to a user, and updating the traffic flow information. Because the traffic flow information is based on the navigation path predetermination result, the predetermination proper navigation path is based on the traffic flow information of a road segment in a time period, wherein the road segment and the time period are corresponding to a predetermination request, and the former two sides form preconditions for each other. The method employs a very economical solution, formulates a good behavior norms for the ordered application of a road and the high efficiency and smooth road traffic, achieves the path planning, predetermination and optimal path navigation for the travel, and solves problems of traffic jams and travel difficulties.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic systems, in particular to a road traffic route guidance method, system and road traffic information service platform. Background technique [0002] With the development of the automobile industry, people pay more and more attention to the perfect experience when using a car while owning a car. Existing in-vehicle devices can already provide users with many services, including services for multimedia needs such as music, video, and pictures, as well as driving navigation services such as real-time road condition information and destination maps. In particular, the use of vehicle navigation systems is becoming more and more popular. The voice prompts of the navigation system can guide the driver to drive, especially when driving in an unfamiliar city, the navigation system can help the user to reach the destination conveniently and quickly. [0003] For the car navigation system, the na...

Problems solved by technology

[0006] However, the current TMC or dynamic navigation system is based on various means of road traffic information collection, requiring huge roadside equipment, communication and broadcasting systems, and heavy asset investment to obtain real-time road condition information. The road section informs the user to adjust the driving route; due to the lack of road traffic reservation information, the travel plan cannot be planned according to the future road conditions, and the problem of orderly use of roads cannot be fundamentally solved

Even if the current TMC or dynamic navigation system immediately informs road congestion sections and congestion levels, sudden traffic incidents, severe weather conditions, traffic control and other real-time road condition information for traffic guidance, the result of the guidance is blind and lacks predictability , such as guiding all vehicles to another free road section, the result is that the congested road section is not necessarily smooth, and the idle road section may become a new congested road section, which instead causes a wider range of congestion
