Urban trunk road bridge and tunnel concentration area sight induction system

Abstract

The invention relates to the technical field of urban main road sight line induction, in particular to an urban main road bridge and tunnel concentration area visual induction system so as to enhance the significance of bridge and tunnel concentration area information induction and improve the safety of driving path selection. The guidance system comprises a bridge and tunnel concentration area different-grade traffic information prediction system, a bridge and tunnel shunting position sight guidance system and a tunnel entrance sight guidance system, and the bridge and tunnel concentration area different-grade traffic information prediction system comprises marks, portal frame stand columns and road surface guide arrows which are arranged according to different sections of a bridge and a tunnel. The bridge and tunnel shunting position sight induction system comprises an indication sign arranged at a shunting point, a diversion line, a self-luminous elastic column and a colored asphalt pattern block on a road surface, and the tunnel entrance sight induction system comprises a portal type variable information plate arranged in front of a tunnel entrance, a drop-shaped deceleration marked line on a tunnel downhill section and a sight induction pattern on a tunnel side wall. And the sight guidance system adapting to urban main road bridge and tunnel concentration area road section characteristics is formed.

Description

technical field [0001] The invention relates to the field of sight guidance for urban main roads, in particular to a sight guidance system for urban main road bridge-tunnel concentration areas. Background technique [0002] At present, on the one hand, with the acceleration of urbanization, the number of overpass roads, level roads and underpass tunnels is increasing, and their interweaving degree is also increasing, and the problem of traffic congestion is increasing; The induction is more complicated. The traffic flow on the bridge level road and the tunnel diversion point increases during peak hours. Often, the driver chooses the wrong route due to unclear guidance information. .

Problems solved by technology

[0002] At present, on the one hand, with the acceleration of urbanization, the number of overpass roads, level roads and underpass tunnels is increasing, and their interweaving degree is also increasing, and the problem of traffic congestion is increasing; The induction is more complicated. The traffic flow on the bridge level road and the tunnel diversion point increases during peak hours. Often, the driver chooses the wrong route due to unclear guidance information.

[0003] In the existing technology, the research on urban arterial roads mainly focuses on the sight guidance of bridges or tunnels, but there are few related studies on bridge-tunnel concentration areas. In terms of existing related technologies, information guidance at diversion points is mainly strengthened However, when the driver drives to the diversion point, there is often not enough time and space to respond to the guidance information, so a complete and safe line-of-sight guidance system for urban arterial roads, bridges and tunnels is urgently needed
