Multi-color city tunnel exit guide visual reference system

Abstract

The invention relates to the field of city traffic safety facilities, in particular to a multi-color city tunnel exit guide visual reference system. The multi-color city tunnel exit guide visual reference system comprises exit section pavement colorful direction signs, side wall colorful guide patterns and curb vertical face marking lines. The multi-color city tunnel exit guide visual reference system starts in the range of 300-500 m in front of city tunnel exits and ends in tunnel exit ramps; different color systems are adopted by different ramp exits; meanwhile, side walls adopt the rhythm type tree patterns, and a 75-degree-angle is formed between the side walls and the uphill direction at the same time and is suitable for tunnel exits of which the uphill gradient is 2-5%; and the colors of the pavement colorful direction signs and the colors of the side wall colorful guide information are kept consistent, so that the pavement colorful direction signs and the side wall colorful guide information jointly form the multi-color tunnel exit guide visual reference system. According to the multi-color city tunnel exit guide visual reference system, the identification difficulty of the direction information and the gradient information for a driver can be lowered, the driver can be effectively guided to drive away from an expected exit, the operation efficiency in a city tunnel is improved, and meanwhile, the tunnel exit section safety is ensured, so that the accidents of tailgating and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of urban traffic safety facilities, in particular to a multi-color urban tunnel exit-oriented visual reference system. Background technique [0002] At present, on the one hand, with the acceleration of urban construction, the number of cross-river tunnels and underpass tunnels is increasing; There are many exits in the situation. Although there are generally two to three exits, the areas that different exits lead to are often far away, the space in the tunnel is limited, the driver's vision is poor, and compared with the general road form, there will be With greater psychological pressure, the exit is often not recognized in time, so there will be deceleration to identify the exit or hesitation at the exit section at the position where the exit exists, which reduces the traffic efficiency of the tunnel and is extremely prone to accidents such as rear-end collisions. At present, there have been studies that...
