Embodiment Construction

[0034] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Aiming at the problem that the existing road condition detection method or device can only detect the road condition information of the road section or area provided with monitoring equipment, and cannot predict the future road condition of the road section or area, the present invention discloses a road section congestion early warning method and device.

[0036] With the development of the Internet of Vehicles (Internet of Vehicles), more and more vehicles are equipped with on-board information systems (including vehicle positioning systems, such as GPS), and their driving status and positioning information are sent to the Internet of Vehicles information center in real time. The road section congestion early warning method ...

Abstract

A road congestion pre-warning method and device. The road congestion pre-warning method comprises the following steps: S1) determining a number alarm threshold value of vehicles and a speed alarm threshold value of vehicles on a pre-warning road; acquiring a number value of vehicles and an average speed value of all the vehicles on a current pre-warning road; S2) judging whether the number value of the vehicles on the pre-warning road is greater than the number alarm threshold value of the vehicles or not, and whether the average speed value of all the vehicles on the pre-warning road is less than the speed alarm threshold of the vehicles or not; and if the number value of the vehicles on the pre-warning road is greater than the number alarm threshold value of the vehicles, and the average speed value of all the vehicles on the pre-warning road is less than the speed alarm threshold of the vehicles, issuing a pre-warning signal. The road congestion pre-warning method is high in reliability and is promising.

Description

technical field [0001] The invention relates to the field of traffic, in particular to a method and device for early warning of road congestion. Background technique [0002] Existing road condition monitoring methods all adopt the real-time information of road sections collected by monitoring devices such as sensors and cameras to analyze, so as to obtain real-time road condition information of the road section. This road condition monitoring method has several deficiencies: 1) This road condition monitoring method only monitors the real-time data of the road section, and cannot give early warning of the congestion situation of the road section; 3) When the monitoring equipment is damaged, the road condition monitoring method cannot monitor the road section. Contents of the invention [0003] Aiming at the problems of unpredictability and insufficient reliability in the existing road condition monitoring method, the invention provides a road section congestion early warn...
