Problems solved by technology

[0004] It can be seen from the above prior art that the existing traffic state mutation impact analysis technology has the following disadvantages: the traffic state mutation impact analysis is based on the detection of traffic events that have occurred, if the traffic event detection is wrong or not in time, the analysis results will not be correct. reliable

Embodiment Construction

[0051]In order to improve the prediction accuracy of traffic influence range, the embodiments of the present invention provide a traffic influence range prediction method and device. In this technical solution, it is not necessary to predict the traffic impact range based on the traffic events that have occurred, that is, known events, but to classify the impact range of the historical traffic state mutation according to the historical data of the traffic state mutation, and use the classification model to determine the real-time traffic. The effect of state mutation data. Therefore, it is possible to predict the range of traffic influence when the event is unknown, avoiding wrong or untimely detection of traffic events, improving the accuracy of prediction results, and providing a reference for short-term prediction.

[0052] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that t...

Abstract

The invention relates to the technical field of traffic intelligent management and control and discloses a forecasting method and device for traffic impact ranges. The forecasting method for the traffic impact ranges comprises obtaining traffic state information; judging whether traffic states suddenly change or not; extracting current decided attribute data of sudden change of the traffic states if the traffic states suddenly change; classifying history sample sets of the sudden change of the traffic states according to the traffic impact ranges and confirming a central value of the decided attribute data which is corresponding to every category of traffic impact range data; obtaining traffic impact range data which is corresponding to the current decided attribute data according to confirmed every category of the traffic impact range data and forecasting the current impact ranges according to the traffic impact range data. According to the forecasting method for the traffic impact ranges, accuracy for forecasting traffic influence ranges is improved.

Description

technical field [0001] The invention relates to the technical field of traffic intelligent management and control, in particular to a method and device for predicting traffic influence range. Background technique [0002] With the rapid growth of my country's motor vehicle population and the saturation of infrastructure construction, the contradiction between supply and demand of urban traffic has become increasingly prominent, and the stability of traffic flow has decreased. Especially during morning and evening peak hours, sudden changes in traffic conditions will interfere with normal traffic, cause road congestion and delays, and reduce road capacity. Sudden change in traffic state is a sudden change in one or some parameters (such as traffic flow, traffic flow speed or traffic flow density) in the traffic flow, which is specifically manifested in the deceleration of upstream vehicles due to traffic obstruction, and the acceleration of downstream vehicles due to sparse v...
