Method for controlling traffic on basis of text mining

Abstract

The invention provides a method for controlling traffic on the basis of text mining. The method includes steps of 100, acquiring traffic control text information; 200, determining radiation ranges of crossroads; 300, determining keywords in the radiation ranges of the crossroads; 400, counting keyword occurrence frequencies and numbers; 500, predicting congestion degrees of the crossroads; 600, adjusting the traffic control information of the crossroads; 700, determining periods of current traffic control adjustment. The method has the advantages that the possible congestion degrees of the specified crossroads within a future period of time can be analyzed according to text information related to traffic control within certain time, the traffic control information of the specified crossroads can be adjusted on the basis of the congestion degrees, accordingly, traffic congestion can be prevented, the travel quality of people can be improved, and the method is favorable for constructing low-carbon society.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a traffic control method based on text mining. Background technique [0002] In recent years, the United Kingdom, Australia, Europe and the United States have established traffic control systems in certain cities. In these systems, most of them are equipped with magnetic loop detectors near each intersection, and the control devices or staff at each intersection input traffic control parameters into the microprocessor through communication networks such as telephone lines, cables, and closed-circuit television lines. , centralized control with a small computer. [0003] At present, there are some self-developed urban traffic control and management systems in China, but there is still a big gap in overall performance compared with similar systems abroad, and they are only used in some small and medium-sized cities. Most of the transportation systems introduced by domestic cities, ...

[0005] (2) Unbalanced traffic structure

The road network traffic capacity is significantly lower than the design requirements and has large fluctuations, travel time is difficult to predict, high traffic accidents, traffic environment deterioration, and travelers are prone to fatigue, etc.
