Embodiment 1

[0124] Location: Select Hefei Nanbei No. 1 elevated road section for implementation case verification.

[0125] Microwave detectors are arranged in the south-to-north direction of this road section. There are 4 lanes in the south-to-north direction of this road section. At the same time, taxis equipped with GPS pass by this road section. The average speed and reliability of the road section in a single sampling period of the road section can be obtained through the background database of the microwave detector. The average speed and reliability of the road section in a single sampling period of the road section can also be obtained through the background database of the floating car. Due to the relatively good precision of microwave detectors in this section, the coverage of floating vehicles is relatively low, and the accuracy of the obtained data is poor.

[0126] Taking the data of the sampling period of 00:00-00:05 on July 4, 2016 as an example, the fusion calculation of ...

Abstract

The invention belongs to the technical field of urban traffic big data mining, and specifically relates to a road traffic hierarchical early warning method based on dynamic traffic information. The method comprises the following steps: acquiring a road average speed; fusing the road average speed; numbering, sequencing and storing the fused road average speed according to a timestamp of a sampling cycle; forecasting a road average speed of next sampling cycle based on a time sequence; and acquiring a road traffic congestion index of next sampling cycle. By adopting the traffic operation hierarchical early warning method for traffic early warning analysis, users can conveniently select and timely change a more appropriate travel route, and traffic managers simultaneously can carry out some traffic regularity studies on meso and macro levels via relevant information to formulate some specific policies. The method is compact in calculation, strong in objectiveness, flexible in calculation, wide in application and high in accuracy of traffic state judgment.

Description

technical field [0001] The invention belongs to the technical field of urban traffic big data mining, and in particular relates to a road traffic classification early warning method based on dynamic traffic information. Background technique [0002] With the continuous development of the city, the contradiction of urban traffic is mainly manifested in the fact that the urban traffic supply cannot meet the growing traffic demand, the problem of traffic congestion on urban roads is becoming more and more serious, and even gradually becomes a global social problem that restricts the harmonious development of cities . Urban arterial roads are the arteries of urban traffic. Timely and accurate prediction and identification of traffic congestion on urban arterial roads in advance, and targeted measures such as traffic control and guidance for congested points can alleviate traffic bottlenecks on arterial roads and reduce traffic congestion. Negative effects of congestion. As far...
