Method and device for processing traffic road information
First Claim
1. A method for processing traffic road information, comprising:
- obtaining acquired traffic parameters of a first target road section and/or the reliability of the traffic parameters within a first preset period, wherein the traffic parameters at least comprise any one or more of the following parameters;
a vehicle time occupancy rate, flow saturation of vehicle flow, and a vehicle speed;
selecting a first fuzzy rule matrix table from a pre-stored set of fuzzy rule matrix tables based on the number of the traffic parameters of the first target road section and/or the reliability of the traffic parameters, wherein the fuzzy rule matrix tables comprise any one of the following types of matrix tables;
a one-dimensional fuzzy rule matrix table, a two-dimensional fuzzy rule matrix table, and a three-dimensional fuzzy rule matrix table;
determining a membership degree for each type of traffic conditions contained in the first fuzzy rule matrix table by calling a membership function, wherein the traffic conditions at least comprise the following types;
Unblocked, Slow and Congested; and
comparing the membership degrees of all types of traffic conditions contained in the first fuzzy rule matrix table to determine a real-time traffic condition for the first target road section within the first preset period.

Abstract
The present application discloses a method and an apparatus for processing traffic road information. The method includes: obtaining acquired traffic parameters of a first target road section and/or the reliability of the traffic parameters within a first preset period; selecting a first fuzzy rule matrix table from a pre-stored set of fuzzy rule matrix tables based on the number of the traffic parameters and/or the reliability of the traffic parameters of the first target road section; determining the membership degree of each type of traffic conditions contained in the first fuzzy rule matrix table by calling a membership function; comparing the membership degrees of all types of traffic conditions contained in the first fuzzy rule matrix table to determine the real-time traffic condition for the first target road section within the first preset period. The present application solves technical problems in solutions of computing traffic states of a road by using a fuzzy rule in the prior art that analysis results for traffic road information are inaccurate due to a single fuzzy rule.
