Crossing without traffic lights and structure of special road for vehicle turning around

Abstract

Disclosed is a structure of a crossroad without traffic lights and a road dedicated for vehicle U-turn, which belongs to the field of urban road construction and is characterized in that: a main road insulation wall is arranged horizontally on a middle roadway of the main road near the crossroad, and the width of the main road insulation wall is the sum of the width of a main road middle insulation belt and the widths of four roadways; that U-turn roadways are disposed on both sides on the main road insulation wall, and the U-turn directions of the U-turn roadways of both sides are opposite; that a branch road insulation wall is arranged horizontally on a middle roadway of the branch road near the crossroad, and the width of the branch road insulation wall of is the sum of the width of a branch road middle insulation belt and the widths of four roadways; and that U-turn roadways are arranged on both sides of the branch road insulation wall, and the U-turn directions of the U-turn roadways on both sides are opposite. The structure can realize purposes of revoking traffic lights from crossroads of major road traffics of a city, can effectively improve utilization rate of roads and can effectively control the phenomenon of traffic jamming.

Description

Technical field: [0001] The invention relates to a crossroad without traffic lights and a special road structure for turning vehicles, which belongs to the field of urban road construction. Background technique: [0002] There are a lot of intersections in the existing urban traffic roads. In order to ensure the safety of the intersections and reduce congestion, the usual solution is to set traffic light signs at the intersections to allow vehicles to travel according to the instructions of the traffic lights. Although this setting solves the orderly traffic of vehicles, it also reduces the efficiency of road use. Due to the design of traffic lights, some vehicles must wait at the crossroads, and during the waiting period of the vehicles, the engine is in an unsaturated working state, which increases the emission of exhaust gas, which is not conducive to the environmental protection of the city. Especially on the roads where the main roads in urban roads and the relatively ...

AI Technical Summary

Problems solved by technology

Due to the design of traffic lights, some vehicles have to wait at the crossroads. During the waiting period, the engine is in an unsaturated working state, which increases the emission of exhaust gas, which is not conducive to the environmental protection of the city.

Especially on the roads where the main roads in urban roads and the relatively wide branch roads cross more, when there are many vehicles, it often happens that the vehicles on one side have not completely passed the intersection, and the green lights of other roads have been turned on, which makes the vehicles very busy. It is easy to gather at the intersection, causing traffic jams and reducing the traffic rate of vehicles

If three-dimensional traffic is established at all intersections where roads intersect, the area will be large and the investment will be high, and it will also affect the natural environment of the city
