Abstract

The invention discloses a method and a device of processing traffic road information. The method comprises steps that traffic parameters of a first target road segment and / or the credibility of the traffic parameters are / is acquired in a first preset period; a first fuzzy rule matrix table is selected from a pre-stored fuzzy rule table set according to the parameter quantity of the traffic parameters of the first target road segment and / or the credibility of the traffic parameters; a membership degree function is invoked, and is used to determine a membership degree of a road condition of every type provided by the first fuzzy rule matrix table; by comparing the membership degree of the road condition of every type provided by the first fuzzy rule matrix table, the real-time road condition of the first target road segment in the first preset period is determined. A technical problem of a scheme adopting a fuzzy rule to calculate a road traffic state of a prior art of inaccurate traffic road information analysis results caused by the single fuzzy rule table is solved.

Description

Technical field [0001] The present invention relates to the field of road traffic, in particular to a method and device for processing traffic road information. Background technique [0002] With the rapid development of the national economy and the acceleration of the process of urbanization, the number of motor vehicles and road traffic in my country has increased dramatically. The contradiction between increasing traffic demand and urban road infrastructure has become the main contradiction of urban traffic, resulting in more and more traffic congestion and congestion. Therefore, it is particularly important for traffic road information, especially traffic jams. By identifying congested road sections, the impact of congestion on road traffic can be minimized. [0003] At present, the recognition of traffic road information mainly uses microwave radar sensors to detect traffic parameters, and use fuzzy rules and membership functions to estimate the road traffic state. However, ...
