Problems solved by technology

[0003] At present, the method of testing the reliability of traffic information mostly adopts the field test method, and the actual traffic operation parameters of the given road are tested on the spot as the true value, and the published traffic information data of the corresponding time period and road section are compared with the true value to detect the real value. Accuracy and reliability, the field observation method is intuitive and effective for the reliability detection of traffic information, but it also has the characteristics of a small sampling range, which makes it difficult to cover all traffic information data, and, due to the subjective cognition of testers and the limitations of information extraction methods Differences, the traffic information will inevitably have deviations compared with the actual true value

Abstract

The invention discloses a method for detecting the reliability of traffic information, which includes: acquiring vehicle sample characteristic data, traffic information spatial stability data, and traffic information temporal stability data within a preset period of time; according to the vehicle sample characteristic data, The traffic information space stability data and the traffic information time stability data calculate information entropy; determine the credibility of the traffic information based on the information entropy. This method is a comprehensive detection method with rich indicators, and its results are highly reliable, which can quantitatively detect the reliability of traffic information.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method, device, system and storage medium for detecting the reliability of traffic information. Background technique [0002] With the substantial increase in the number of vehicles, traffic congestion has become a problem that large and medium-sized cities in China must face. In this context, people have developed dynamic traffic information services, which play a very important role in guiding the public to travel and managing traffic congestion. role. The accuracy and reliability of dynamic traffic information is very critical to users of traffic information. For public travel, wrong traffic information will lead to unreasonable route planning and selection, waste traveler's time, increase social energy consumption and pollution emissions; for social management, wrong traffic information will prevent the government from fundamentally discovering Traffic ...
