detailed description

A method for improving the traffic capacity of an intersection, first, the steps of preparing the measures are as follows: 1 setting a first parking line 1 and a second parking line 2 on a half road leading to the intersection, the first parking line 1 is adjacent to the intersection, and the second The parking line 2 is located behind the first parking line 1; 2 the first traffic indicator, the second traffic indicator and the third traffic indicator are arranged in the area of the intersection; the use of the traffic indicator is specified: the first traffic indicator The to-be-stopped motor vehicles that are specifically corresponding to the second parking area behind the second parking line 2 and that are traveling at the forward intersection are respectively stopped on the lanes respectively marked with the corresponding driving direction signs behind the second parking line 2, the second traffic The indicator specifically corresponds to the vehicle that is arranged behind the second parking line 2 and is arranged to stop or drive on the lane marked with the same driving direction sign, and sequentially drives through the second parking line 2 and sequentially stops at the first parking line 1 And a first parking area between the second parking line 2, the third traffic indicator specifically corresponding to prompting the lane behind the second parking line 2 to enter the first parking area via the lane marked with the same driving direction sign The motor vehicle that has continuously passed the first parking line 1 passes through the first parking line 1 and follows the same driving direction mark corresponding to the vehicle that is behind the second parking line 2 and that is to be continuously passed over the first parking line 1 Driving in the direction indicated; Second, the steps of the control measures are: 1 using the first traffic corresponding indicator to prompt the second parking zone located behind the second parking line 2 and the motor vehicles traveling at the forward intersection respectively stop at the second parking line 2 behind the respective lanes marked with the direction of travel sign; 2 using the second traffic indicator to prompt the rear of the second parking line 2 and located in the lane marked with the same direction of travel sign Passing through the second parking line 2 and sequentially sorting the first parking area between the first parking line 1 and the second parking line 2; 3 using the third traffic indicator to prompt the rear of the second parking line 2 The lane of the same direction of travel sign enters the first parking zone and the vehicle to be continuously passed over the first parking lane 1 passes the first parking lane 1 and follows the second parking lane 2 and the above-mentioned to be continuously passed the first stop The motor vehicle of the vehicle line 1 travels in the direction indicated by the same traveling direction sign.

The first traffic indicator, the second traffic indicator, and the third traffic indicator are any traffic lights that can transmit their respective corresponding signals to the naked eye of the motor vehicle driver by visible light.

When one direction is a green traffic signal and the vehicle presses the signal through the intersection (such as the north-south direction), and the vehicle in the other direction (east-west direction) is in the parking waiting state, if the east-west parking line extends 100 meters backward, Then all the vehicles waiting in this direction will be reared 50 to 100 meters, and the yellow arrow lights will guide these vehicles to the original intersection stop line to wait for the passage. When the green signal light is on, these vehicles can pass the intersection, the other one can pass the intersection, the other The direction (North-south direction) is the same. The principle of passing the intersection is as shown in the following figure, and the unified standard symmetric intersection is taken as an example for illustration.

As shown in Figure 1: When the north-south vehicle is placed, the north-south vehicle turns left and the east-west direction and the left-turn vehicle are in the parking waiting state. The east-west direction should be 100 meters behind the original parking line, and an additional parking is provided. Line (the original parking line is the No. 1 parking line (the first parking line 1), and one of the parking lines after the original parking line is the No. 2 parking line (the second parking line 2)), then in the east-west direction, in the signal light A yellow left turn arrow is added to the system to indicate the function. When the yellow left turn signal indicates, the vehicle parked on the left turn lane of the No. 2 parking line can enter the waiting area of the No. 1 parking line. These vehicles can occupy three lanes, and the vehicle in the direction is still on the 2nd. Waiting at the parking line. When the north-south direct-going vehicle is parked, the left-turning vehicle can be turned to the east-west direction. Then the left-turning vehicle changes from the traditional one lane to the three-lane crossing, and the efficiency of the motor vehicle passing through the intersection is increased by 200%; When turning the vehicle to the left, you can guide the left-turning left-turning vehicle into the No. 1 parking line area, as in the above.

As shown in Figure 2: When turning the left-turning vehicle in the north-south direction, use the yellow signal light to guide the straight-moving vehicles in the east-west direction into the three lanes of the No. 1 parking line area. When the north-south left-turning vehicle is parked, it can be A straight-through vehicle that puts things in the direction of the east. Then, the straight-through vehicle changes from the traditional two lanes to the three lanes through the intersection, and the efficiency of the motor vehicle passing through the intersection is increased by 50%; when the east-west direction is placed on the straight-through vehicle, the north-south direct-going vehicle can be guided into the No. 1 parking line area. Waiting, the method is the same as above.

The working principle of adding the yellow guiding command function in the signal light command system is as follows. The role is as follows: 1. The concept of the traditional intersection is developed in depth, and the connotation of the intersection concept is expanded. 2, more fully utilize the intersection resources, the efficiency of motor vehicles through the intersection can be increased by more than 50%. That is to say, adding a yellow guiding command function in the signal light command system can basically solve the problem of traffic congestion at the intersection.

The invention can be flexibly utilized according to the actual situation of the intersection in actual operation, as shown in FIG.

In the signal light command system, the yellow guiding command function can be solved by the yellow light flashing and the green light flashing and the red light flashing; it can also be solved by adding the signal light to command the system color and color change; the signal light system can be used with the logo and the marking line. The solution to the problem is solved. The intersection referred to in the present invention is an intersection formed by the intersection of two or more existing roads, such as a typical intersection, a T-junction, etc., and also includes a roundabout.

A yellow pilot command function signal is added to the signal command system to assist the red signal and the green signal. This signal is a signal subordinate to the red signal signal and the green signal signal in the Road Traffic Safety Law of the People's Republic of China. There is no contradiction between this signal and the law. There is no contradiction with the Road Traffic Law of other countries in the world. The traffic accidents and vehicle operating rules that occur as a result can be standardized and handled in full accordance with the existing road traffic laws of each country.
