Embodiment Construction

[0024] A highway roadside early warning device according to the present invention is installed in highway traffic accident-prone areas and roadside positions of highway road line gradient sections, and mainly consists of a detection unit, a communication unit, a main control unit, and an early warning unit. , storage unit, power supply unit, etc., such as figure 1 , figure 2 As shown, it mainly realizes the speed detection of expressway vehicles, the extraction of traffic flow operation parameters, the evaluation and early warning of vehicle operation safety status, and the monitoring of expressway road operation status. Provide data support for highway operation status monitoring.

[0025] A kind of expressway roadside warning device that the present invention proposes, the concrete flow process of its work is:

[0026] 1) Detection unit

[0027] The semiconductor laser module in the detection unit faces the highway at a certain oblique angle, and emits a double-beam puls...

Abstract

The invention relates to the technical field of traffic safety, particularly relates to a highway roadside early warning device, and provides the highway roadside early warning device which can prevent highway vehicle rear-end collision and speeding. The roadside early warning device is mainly composed of functional units of a detection unit, a communication unit, a master control unit, an early warning unit, a storage unit and a power supply unit and mainly realizes highway operating vehicle speed detection, traffic flow operating parameter extraction, vehicle operating safety state assessment and early warning and highway road operating state monitoring so that highway vehicle rear-end collision and speeding can be prevented, and data support of highway operating state monitoring can be provided for highway managers.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an expressway roadside early warning device. technical background [0002] In recent years, with the continuous increase of expressway mileage in our country, on the one hand, it has met people's growing urban and intercity traffic travel needs, making people's travel more convenient, efficient, fast and comfortable, and driving the rapid development of social economy; On the other hand, due to the generally high running speed of expressway vehicles, traffic accidents such as vehicle rear-end collisions and collisions caused by high-speed and overspeeding are common, especially in many adverse weather conditions such as fog, rain, snow, sandstorms, and dusk. Traffic accidents such as rear-end collisions and collisions frequently occur on expressways, which cause serious injuries and huge losses to the life and property safety of expressway travelers. [0003] At present, ...
