Problems solved by technology

[0004] The purpose of the present invention is to provide a method and device for calculating road congestion and slowness combined with free flow, which has the advantage of strong applicability, and solves the problem that the existing method for defining road conditions by road use speed is fixed, and it is not easy to adapt to various The road conditions of each link are likely to be too scattered in the process of road condition definition model processing, and the back-end conversion rules are not uniform, resulting in inconsistent road conditions referenced by different locations, and the process links are not streamlined, resulting in delays

Abstract

The invention discloses a method and a device for calculating road congestion and slowdown state in combination with free flow. Network traffic status and speed. The invention has the advantages of strong applicability, and solves the problem that the existing method of defining the road condition state by using the speed of the road is fixed, which is inconvenient to adapt to various road conditions, and easily causes the processing links of the road condition definition model of each link to be too scattered, and the back-end conversion rules Not unified, resulting in inconsistent reference road conditions at different locations.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and a device for calculating road congestion and slowdown states in combination with free flow. Background technique [0002] The floating car model is the main model for road condition data collection. This method mainly uses the GPS terminal installed in the vehicle volume to record the driving speed and direction of the floating car, and sends back information to the traffic monitoring center at regular intervals. The road conditions are calculated by road matching. When enough vehicles are installed with this kind of GPS terminal, a dynamic real-time road condition information detection network can be formed. In the existing method, after the traffic flow information results are generated after fusion and release, the traffic flow information results are generated using different location reference points. The city handles the traffic conditions referenced by...
