Convenient and smooth flyover crossroad traffic building without traffic light

Abstract

The invention relates to a convenient and smooth flyover crossroad traffic building without a traffic light, consisting of ground lanes, underground tunnels and ground flyovers. The ground roads are characterized in that straight lanes and right-turn lanes with separated direct and retrograde lanes are arranged at longitudinal crossroads, and right-turn lanes with separated direct and retrograde lanes are arranged at transverse crossroads. The underground tunnels are straight lanes with separated direct and retrograde lanes at the transverse crossroads. The ground flyovers consists of four left-turn overhead channels which are communicated with the left-turn lanes of the longitudinal crossroads and the left-turn lanes of the transverse crossroads, and the back of the opening faces to the crossroads. In the invention, the condition that automobiles from each direction can run on the own lanes can be realized without arranging the traffic light, and the automobiles can smoothly run straightly, turn left, turn right and take a U-turn. The invention has advantages of reasonable shunt, high traffic flow rate, simple and reasonable structure, low cost and convenient use.

Description

(1) Technical field: [0001] The invention relates to a traffic building at an urban road crossing, in particular to a convenient and smooth crossroad traffic building without traffic lights, which belongs to the field of urban public traffic road construction. (two) background technology: [0002] With the development of the economy and the improvement of people's living standards, more and more people use cars as a means of transportation, which brings great convenience and speed to people's work and life, and also creates great efficiency and benefit. However, with the increasing number of vehicles, urban traffic has brought enormous pressure. Because the construction of existing urban road traffic can't keep up with the pace of urban development, there is widespread traffic congestion in urban streets, especially the congestion at intersections is becoming more and more serious, almost at all intersections, especially during peak traffic periods. , there are motor vehic...

AI Technical Summary

Problems solved by technology

[0003] Although traffic light control systems are installed at crossroads to direct traffic, because vehicles have to go straight, turn left or turn right at crossroads, and the time for changing traffic lights is short, there are often more vehicles gathered during the period when the red light is on than the green light The number of vehicles that can pass through in one cycle of release will easily lead to a large number of vehicles waiting in line and stranded, thus causing a large number of vehicles to wait for vehicles and traffic jams

Especially when the traffic light changes from green light to red light, the vehicle only drives to the middle of the intersection, which is in a dilemma, thus affecting the passage of vehicles in the other direction.

In this way, it not only wastes a lot of time for people, affects the speed of driving, brings a lot of inconvenience to people's smooth travel, but also reduces the efficiency of traffic, and is also prone to ...
