Traffic flow deriving technology of too-close road segment of tunnel exit and interchange exit
The invention discloses a traffic flow deriving technology of a too-close road segment of a tunnel exit and an interchange exit. When the distance between the tunnel exit and the interchange exit is smaller than the distance constraint, a newly-built tunnel is broadened, an auxiliary lane is additionally arranged, the auxiliary lane is arranged according to the requirement of the length in front of a flow dividing point by 600 m, strengthened traffic marks and marked lines are arranged in front of a tunnel entrance or in front of the flow dividing point in a tunnel, and strengthened traffic marks and ground marked lines are arranged on a built highway, in front of the tunnel entrance and inside the tunnel. According to the traffic flow deriving technology of the too-close road segment of the tunnel exit and the interchange exit, the accident rate of a constraint type interchange type vertical crossing exit is reduced, safety of interchange type vertical crossing of the highway is improved, and the technical support is provided for improving the road traffic capacity, the service level and the like
