Problems solved by technology

[0004]However, the existing road traffic operation situation prediction methods mainly use basic prediction models and traffic flow operation traffic parameter data to predict short-term changes, and the accuracy of the prediction results is biased. Low
Moreover, the collected parameters are single and cannot comprehensively cover various situations. When the actual traffic situation is more complex, it is difficult to predict and analyze the situation.

Abstract

The embodiment of the invention discloses a traffic operation situation evaluation method, system and device. According to the technical scheme provided by the embodiment of the invention, the data characteristics of each time period in a plurality of historical dates, the traffic congestion index of the corresponding time period and the traffic congestion index of the next time period are acquired to construct a traffic transportation situation instant situation evaluation model. The data characteristics are integrated with data factors in various aspects, so the constructed model can adapt to complex scenes, the traffic operation condition of the next time period can be predicted based on the current data characteristics, passengers can be helped to travel efficiently, and the traffic operation efficiency is further improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of traffic data processing, and in particular to methods, systems and devices for assessing traffic operation situations. Background technique [0002] With the increase of the urban population and the number of motor vehicles, urban traffic congestion and delays often occur, the efficiency of urban traffic operation is low, and the travel efficiency decreases. [0003] The analysis and prediction of road traffic operation situation is the basis for intelligent traffic system to implement road traffic regulation and control. The accurate prediction of road traffic operation situation can ensure the safe and smooth operation of traffic flow, help road traffic users to plan reasonably according to the changes of road traffic operation situation in the future, and help road traffic managers to know the future road traffic operation situation in advance so as to facilitate Precisely ...
