Problems solved by technology

[0005] However, the route guidance scheme based on user balance and optimization to solve the model is often theoretical and difficult to implement in practical applications. For the direct diversion route guidance method, it often relies on the real-time monitoring traffic data of the expressway, and only considers the dredging at the bottleneck , less consideration is given to the overall road network and road use rules and impacts

Embodiment 1

[0042] This embodiment provides a route guidance method based on a road usage pattern. By analyzing the road usage pattern, the traffic flow can be guided to rationally utilize the road network resources, such as figure 1 shown, including the following steps:

[0043] Step 1. Extract the road information and road attributes of the main road sections (highways and national and provincial roads) and branch road sections (municipal roads) within the target area to construct a road traffic network;

[0044] Step 2: Obtain the traffic flow and traffic accident information of each main road section, determine the congestion and abnormal conditions of each main road section, and take the main road section where the congestion or abnormal situation occurs as the target road section.

[0045] Specifically, the checkpoint data of the main road section is obtained, the traffic flow of the main road section is obtained by processing, the curve of the real-time main road section flow chang...

Embodiment 2

[0073] This embodiment provides a path guidance system based on a road usage pattern, which specifically includes the following modules:

[0074] A target road section determination module, which is configured to: obtain the traffic flow and traffic accident information of each main road section, determine the congestion and abnormal conditions of each main road section, and use the main road section where the congestion or abnormal situation occurs as the target road section;

[0075] a main origin and destination determination module, which is configured to: obtain the travel trajectories of all vehicles passing through the target road section within a certain historical time period, and determine the main origin and destination points of the target road section;

[0076] The traffic distribution module is configured to: for each pair of main origin and destination points, calculate the saturation representative value of each candidate path between the main origin and destina...

Embodiment 3

[0079] This embodiment provides a computer-readable storage medium on which a computer program is stored, and when the program is executed by a processor, implements the steps in the path inducing method based on the road usage pattern described in the first embodiment above.

Abstract

The invention provides a path guidance method and system based on a road use mode, and the method comprises the steps: obtaining the flow and traffic accident information of each main road section, judging the congestion and abnormal conditions of each main road section, and enabling the main road section with the congestion or abnormal conditions to serve as a target road section; acquiring driving tracks of all vehicles passing through the target road section in a certain historical time period, and determining main origin and destination points of the vehicles passing through the target road section; for each pair of main origin-destination points, the saturation representative value of each candidate path between the main origin-destination points is calculated, and the flow of the main origin-destination points is allocated to each candidate path on the basis of the saturation representative value of each candidate path. And the path induction efficiency and effectiveness are improved.

Description

technical field [0001] The invention belongs to the technical field of route induction, and in particular relates to a route induction method and system based on a road usage pattern. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the congestion problem in the high-traffic scenario of the expressway cannot be ignored, and the large-scale congestion on the expressway under the conditions of holidays and sudden changes has also seriously affected the travel of residents. By inducing and diverting travelers in the upstream of the congested road section, reducing the pressure on the congested road section and accelerating the process of congestion dissipation, it is an important method of ensuring traffic operation safety. [0004] The route induction method for route solving mainly relies on the traffic allocation algorithm, mai...
