Problems solved by technology

However, this method requires a large turnover area for high-density traffic flow
In addition, if a large number of left-turning vehicles are not well controlled, congestion will still occur
[0006] Therefore, it is difficult to fundamentally solve the conflict between left-turning vehicles and straight-going vehicles only by time interval control.
[0007] The most fundamental and effective way to solve the problem is to build bridges, but this requires a lot of money, a large site and a long construction period, and there are many road intersections where bridges cannot be built
Even if the overpass is built, the detours of vehicles increase the cost of driving and increase the burden on national energy

Embodiment 1

[0056] Figures 1 and 2 show the lane settings of the present embodiment: each road at the intersection is provided with two forward straight lanes, two reverse straight lanes, a right turn straight lane and a left turn lane, as shown in the figure , the intersection includes four roads 11, 12, 13 and 14, assuming that 11 and 13 are the first pair of roads, 12 and 14 are the second pair of roads, the lane setting of each road is from left to right as the left turn lane 120, The reverse straight lane 130 , the forward straight lane 140 and the right turn lane 150 , according to the above settings, as shown in FIG. 2 , each lane is marked with a left turn sign 121 , reverse right turn and reverse straight sign 131 respectively from left to right. , reverse left turn and reverse straight sign 132, go straight sign 141 and turn right sign 151. There is a separation zone 002 between the forward through lane and the reverse through lane. At a distance before each road from the inter...

Embodiment 2

[0065] The road setting is the same as in Example 1, and the method for implementing full circulation at the intersection is:

[0066] 1) All the traffic lights of the four roads at the intersection are red, and all the pre-left-turn traffic lights of the four roads are green at the same time, indicating that on the four roads, one or more of the left-most lanes are on the left. Vehicles in the lane that want to turn left turn left into the left-turn lane.

[0067] 2) After being open to traffic for a period of time, start all left turns on the first pair of roads 11 and 13, the right turn and straight traffic lights are green, and simultaneously start all left turns on the second pair of roads 12 and 14, right turn and straight traffic lights are At the same time, all the pre-left-turn traffic lights on the four roads are turned red to achieve full circulation, as shown in Figure 3.

[0068] 3) After being open to traffic for a period of time, start all left turns on the sec...

Embodiment 3

[0072] The road setting is the same as in Example 1, and the method for implementing full circulation at the intersection is:

[0073] 1) Activate the left turn of the first pair of roads 11 and 13 at the intersection, the right-turn traffic signal is green, and the pre-left-turn traffic signal is green, the traffic signal of the start straight lane is red, and the second pair of roads at the intersection is activated All left-turn, right-turn and through-lane traffic signals on 12 and 14 are red, as well as pre-left-turn traffic signals.

[0074]2) After opening to traffic for a period of time, keep the left-turn traffic lights of the first pair of roads 11 and 13 at the intersection as green lights, right-turn traffic lights as green lights, start the traffic lights of the straight lane as green lights, and start the pre-left turn traffic lights as red lights , keep all the traffic lights of the second pair of roads 12 and 14 at the intersection as red lights for left turns,...

Abstract

The invention provides an all-pass method to locate roads of crossways, control signal lamps and traffic. It realizes all-pass of crossroads, which shortens the waiting time of vehicles, improves the traffic capacity and amends the phenomena of traffic jam. All-pass allows six kinds of vehicles on to-from roads (coming and going vehicles both contain three driveways of straight-going, left and right turning) transiting simultaneously. The invention arranges vehicles needing left turning on left side of roads when they entry the crossroads. When green light is started, the left-turning vehicles have no conflict with the straight-going ones, which realizes the all-pass on the six directions of the crossroads without cross of different directions. It can arrange left-turning vehicles into the left driveways in the time for another vehicles controlled by red light without adding waiting time. With a unique design of driveways, the invention makes use of vacancy of vehicle on converse driveways in red-light waiting time and matches corresponding control to realize all-pass. It shortens the waiting time of vehicles at crossroads, improves the traffic capacity and amends the phenomena of traffic jam.

Description

technical field [0001] The invention relates to a traffic signal light control method for setting roads and controlling the running direction of motor vehicles. Background technique [0002] With the rapid development of the economy and the rapid increase of the number of vehicles, the phenomenon of traffic congestion is becoming more and more serious. Especially in our country, the traffic problem has become a serious problem that cities have to face. Traffic congestion has caused a great waste of time and energy, which has reached a very headache. The traditional solution is to widen the roads. But in fact the places most likely to cause traffic congestion occur at road intersections, so widening roads will not solve the problem of existing traffic congestion proportionally. [0003] Traditional road intersection traffic control is limited by left-turning vehicles to vehicles in other directions, so that each time a vehicle passes through a road intersection, only two la...
