Expressway driving early warning system and method

Abstract

The invention discloses an expressway driving early warning system and method. According to the invention, respective satellite positioning data of a key vehicle early warning device and a common vehicle early warning device is sent to a background data processing system; and the background data processing system determines whether the distances between key vehicles, and between key vehicles and common vehicles and the relative speed meet an early warning condition and sends corresponding early warning information to the key vehicle early warning device and the common vehicle early warning device, thereby achieving objectives that possibly occurring dangers can be warned earlier and avoided in advance and driving safety on the expressway is improved. According to the invention, by use of information technology of mobile Internet, real-time continuous tracking and monitoring of vehicle running states are achieved; the function that beyond visual range running early warning function based on early warning scene real-time identification is achieved; and occurrence of accidents of collisions and rear-end collisions on the expressway can be effectively reduced.

Description

technical field [0001] The invention relates to the field of expressway safety assurance, in particular to an expressway driving early warning system and method. Background technique [0002] The total mileage of expressways in my country has exceeded 120,000 kilometers, connecting prefecture-level administrative centers across the country, medium-sized and above cities with an urban population of more than 200,000, important transportation hubs, and important border ports. With the continuous increase in the mileage of expressways and the continuous optimization of network layout, the turnover of passenger and cargo transportation has increased rapidly, and the proportion of large passenger and cargo transportation vehicles and dangerous goods transportation vehicles has grown rapidly. With the booming e-commerce economy, The volume of large-scale cargo transportation will continue to grow rapidly. [0003] According to statistics, among the major traffic accidents on expr...

AI Technical Summary

Problems solved by technology

[0006] First, the vehicle-mounted satellite positioning terminals currently installed on "two passengers and one danger" vehicles have poor real-time data interaction capabilities, and it is difficult to achieve real-time data communication with the existing traffic monitoring system on expressways. At a certain moment, there may be a driving state that affects each other between "two passengers and one dangerous" vehicles and ordinary vehicles (such as ordinary cars), that is, the potential risk of rear-end collision or collision will increase at a certain moment , but the current technology is difficult to achieve continuous tracking and monitoring of such mobile risks, let alone early warning and over-the-horizon warning

[0007] Second, large freight vehicles that are not in the category of "two passengers and one danger" driving on the expressway may also be a potential source of mobile risk. Since the vehicle-mounted satellite positioning terminal is not installed, it is difficult to track and monitor them in real time

[0008] Third, driving safety on expressways is greatly affected by environmental factors such as weather. The current technology has a weak ability to dynamically adjust to changes in the driving environment. If a short-term abnormal weather occurs on a certain part of the expressway, it cannot respond quickly, which is not conducive to driving safety manage

[0009] Fourth, the current regulatory technology for "two passengers and one dangerous" vehicles focuses on the application of law enforcement services, and the real-time early warning function for safe driving is weak
