A Traffic Control Method Based on Text Mining

Abstract

The present invention provides a traffic control method based on text mining, comprising: step 100, obtaining text information of traffic control; step 200, determining the radiation range of the intersection; step 300, determining keywords within the radiation range of the intersection ; Step 400, counting the occurrence frequency and times of the keywords; Step 500, predicting the degree of congestion at the intersection; Step 600, adjusting the traffic control information at the intersection; Step 700, determining the current round of traffic control adjustment cycle. According to the text information related to traffic control within a certain period of time, the present invention can analyze the possible congestion degree of the designated crossroads for a period of time in the future, and adjust the traffic control information of the designated crossroads based on the congestion degree, so as to avoid traffic congestion and improve people's travel quality , Conducive to building a 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. 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, especiall...
