A line-of-sight guidance system in the merge area of ​​an underground interchange

Abstract

The invention relates to the technical field of traffic safety, in particular to an underground overpass merging sight guidance system, which includes a side wall sight guidance system, a sign guidance system and a road surface guidance system. Lines, guiding large arrows, guiding small arrows and LED reference strips; the sign guidance system is composed of flexible warning columns, merging warning signs, yield signs and tunnel indicators; the road surface guidance system is composed of raised road signs, diversion lines, virtual and real steering Composed of arrows, yield markings, fishbone-shaped deceleration markings and virtual and solid markings. With such a structural setting, through the side wall sight guidance system, sign guidance system and road surface guidance system, the driver's visual environment can be effectively improved, the effect of guidance and indication of traffic flow on secondary roads can be enhanced, and the traffic efficiency in the merge area can be improved. The speed and distance of vehicles on the main road and secondary road can be adjusted to improve the safety of the merge area.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an underground overpass merging line of sight induction system. Background technique [0002] At present, on the one hand, more and more tunnels, underground interchanges, and interweaving are becoming more and more with the urban construction. Research on the theory of traffic flow system in the urban underground interchange junction area, so the lack of hierarchy, systematicness, and accuracy of the guidance information often leads to driving difficulties for drivers, resulting in congestion and traffic accidents in underground interchanges, and affecting the regional traffic environment . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an underground overpass merging line of sight induction system, which improves the driver's visual environment, enhances the effect of inducing and indicating the traffic f...
