Problems solved by technology

[0002] There are no signal-controlled level crossings on arterial roads in mountainous areas, and they usually face challenges that are not conducive to road driving conditions such as insufficient line of sight, passing through towns, many mixed traffic conflicts, irregular access management, more adverse weather, and low visibility at night. When facilities protection and safety management technology are not in place, no signal control road intersections are often prone to accidents due to the existence of driving conflict points
At intersections that are not suitable for building signal-controlled traffic facilities, how to effectively improve road safety and traffic efficiency is an urgent problem to be solved in the field of road safety early warning technology

Abstract

The invention relates to a real-time risk early warning system for a no-signal control intersection of a trunk highway, and belongs to the technical field of road safety early warning. The early warning system comprises a plurality of distributed wireless early warning units, which comprise a logic controller, a power supply module, VMS early warning signs, a vehicle detector group and a wirelessdigital transmission communication module. The real-time risk early warning system for a no-signal control intersection of a trunk highway provided by the invention comprehensively considers the interaction relationship of the traffic flow between the secondary line and the main line near the intersection, lays the VMS early warning signs at the fixed distance between the main line and the secondary line by adopting priority warning concept, and dynamically displays early warning messages according to the vehicle passing information detected by the lane to warn the vehicles to enter the intersection in advance, so as to buy more reaction time for the drivers, thereby greatly reducing the probability and severity of accidents, and also reducing the risk of driving without signal-controlledintersections.

Description

technical field [0001] The invention belongs to the technical field of road safety early warning, and in particular relates to a real-time risk early warning system for a non-signal-controlled intersection of an arterial highway. Background technique [0002] There are no signal-controlled level crossings on arterial roads in mountainous areas, and they usually face challenges that are not conducive to road driving conditions such as insufficient line of sight, passing through towns, many mixed traffic conflicts, irregular access management, more adverse weather, and low visibility at night. In the absence of facility protection and safety management technology, unsignalized intersections are often prone to accidents due to the existence of driving conflict points. At intersections that are not suitable for building signal-controlled traffic facilities, how to effectively improve road safety and traffic efficiency is an urgent problem to be solved in the field of road safety...
