Vehicle road early warning system for improving traffic safety in fog region of highway

Abstract

The invention discloses a vehicle road early warning system for improving the traffic safety in a fog region of a highway. The system comprises an early warning control unit, a plurality of traffic induction units, visibility detection units, a plurality of short-range communication modules and the like, wherein the traffic induction units, the visibility detection units, short-range communicationmodules and the like are arranged on stand columns of crash barriers of the highway along a line. A vehicle position identification unit is in communication with the early-warning control unit through remote communication and distribution of satellites and the short-range communication modules on the highway so as to ensure the communication effect. According to an output result of the early-warning control unit, a driver is prompted to run safely through the traffic induction units and the vehicle-mounted vehicle position identification unit. For vehicle driving in a fog region of the highway, the safety operability and guidance of the driver can be improved, the potential safety hazard of the vehicle driving under low visibility can be effectively reduced, and safe driving of the highway can be guaranteed; and meanwhile, vehicles on lanes can be guided in real time, so that the traffic efficiency of the highway is fully exerted to the maximum extent, and the safe and efficient development of a highway traffic system are promoted.

Description

technical field [0001] The invention belongs to the technical field of road safety, in particular to a vehicle road early warning system for improving driving safety in foggy areas of expressways. technical background [0002] In the field of transportation, the construction mileage of expressways is increasing continuously, and some areas passing through waters and areas with humid climates are prone to fog sections. Respectively to disorderly control of vehicle speed, easily cause traffic accident, bring heavy loss to people's life property and social economy. The efficient operation of the lane guidance facilities on the expressway is particularly important for the driver's driving safety, and its reliability and accuracy are also crucial to ensure safety. [0003] At present, the preventive measures taken in areas prone to dense fog in China are mainly to install yellow guidance signs on both sides of the road to induce vehicles entering the foggy area to move forward s...

Problems solved by technology

These systems and methods do not consider the visual distance of the rear driver to the warning lights under different visibility conditions, nor consider the safety distance under the comprehensive safety factors of road linearity, road surface adhesion coefficient and vehicle speed under driving conditions, and at the same time for multi-lane roads. Knowing the situation ahead in this lane greatly reduces road traffic capacity

At the same time, vehicle sensing equipment is also easily affected by climate conditions, resulting in a decline in sensing capabilities. In order to ensure accuracy, too many monitoring devices increase investment and increase maintenance costs.
