200 1 began to pay attention to the causes of Chinese-style crossing, and found that the main reason for this phenomenon was unreasonable traffic management design. So, I designed a reasonable traffic intersection setting scheme and sent it to the Traffic Management Bureau of the Ministry of Public Security, the Traffic Management Research Institute of the Ministry of Public Security and the traffic management departments of various provinces and cities. Unfortunately, there was no reply. Therefore, I have reason to believe that the initiator of Chinese-style road crossing is the Ministry of Public Security of China.
The following is my letter (content) to the relevant departments of the Ministry of Public Security in my early years and the traffic intersection setting scheme I designed.

Traffic Management Bureau of China Ministry of Public Security:
Traffic Management Bureau of Guangdong Provincial Public Security Department:
We are a group of citizens in Foshan City, Guangdong Province, and now we jointly write to your traffic management department, urging your department to change the unreasonable design of the traffic command system at the intersection of urban plane traffic and give pedestrians the right to walk safely.
When we teach children to cross the road, we find an unreasonable phenomenon of traffic management that is not noticed: at the intersection of plane traffic, pedestrians and non-motor vehicles must compete with motor vehicles whether they want to cross the road with traffic lights or not. Because the traffic lights at most intersections in China are commanded in this way: Take the intersection as an example, when a motor vehicle in a certain direction turns green, the pedestrian command light in the same direction turns green at the same time, but the green light does not mean pedestrian safety. When crossing the road, pedestrians must grab the road with motor vehicles turning left and right in the same direction. Green light is not safe for pedestrians, and red light and green light are indistinguishable for pedestrians, which also means danger. Such a traffic light command mode makes it impossible for parents to teach their children to cross the road. The safest way to teach children to cross the road is to tell them not to look at the command lights, to live with adults, and to follow when they see a group of people crossing the road.
Such a traffic command design, the green light is a dangerous misleading to pedestrians; This traffic command design has caused the urban residents in our country to develop the habit of ignoring the traffic lights, and also caused the inefficiency of traffic guidance at the intersection of urban plane traffic in our country, which greatly increased the labor intensity of traffic police. We strongly urge the relevant traffic management departments to change this phenomenon immediately and give us the right to walk safely.
We enclose a copy of "Design of Urban Plane Traffic Intersection" for you. This design can effectively overcome many shortcomings of the existing plane traffic intersection, hoping to play a role in attracting jade from your place. I hope your department will give more consideration to those pedestrians who are just flesh and blood when introducing relevant management rules. Please.

Leader of Traffic Management Research Institute of Ministry of Public Security:
Hello! I am an ordinary citizen of Foshan City, Guangdong Province. When my daughter was very young, I taught her as traffic propaganda taught her: "When crossing the road, the red light must stop and the green light must pass." My daughter strictly followed this instruction, but she was still injured by a motorcycle on the zebra crossing at the intersection. Then I noticed that the main reason for my daughter's car accident was you! Why do you say that? Because your traffic law allows motor vehicles to turn left and right at the green light and pedestrians to grab the road. This is the main cause of my daughter's car accident.
In any city in China, pedestrians can find such a phenomenon when they walk: to cross the road, they must grab the road with motor vehicles. Because the traffic lights at most intersections in China are commanded in this way: Take the intersection as an example, when a motor vehicle in a certain direction turns green, the pedestrian command light in the same direction turns green at the same time, but the green light does not mean pedestrian safety. When crossing the road, pedestrians must grab the road with motor vehicles turning left and right in the same direction. A green light means unsafe for pedestrians, and it represents danger just like a red light. Your leader might as well try to teach your children to cross the street. It is not difficult to find that there is no way to teach them to cross the road. The safest way to teach children to cross the road is to tell them not to look at the command lights, to live with adults, and to follow when they see a group of people crossing the road. That's how I taught my children to cross the street later. Crossing the road like this really makes my children safer. No way, both of them are harmless!
Such traffic command not only deprives pedestrians of the right to cross the road safely, but also makes China residents form the habit of ignoring traffic lights, which leads to the low efficiency of traffic guidance at urban intersections in China and greatly increases the labor intensity of traffic police.
In order to seek to change the phenomenon here, I designed a command method for plane traffic intersections many years ago. After repeated deliberation and improvement of the design, I think the design is reasonable, with wide adaptability, less investment and easy to implement at most intersections. Now I will send you the design scheme of this method together with this letter for your reference. I hope you can influence the traffic decision-making department, change the unreasonable traffic command phenomenon quickly, and let pedestrians get equal rights with motor vehicles at intersections.
In order to express my strong desire to change the unreasonable traffic command mode, I promise that if the Ministry of Public Security promotes this traffic command mode nationwide, I will personally donate 30 thousand yuan to you. This behavior is purely an expression of my feelings and has no other meaning. I hope I can understand it.

Traffic setting at efficient intersections
This setting is suitable for+intersection, Y intersection or other intersections with more than four lanes and a large number of motor vehicles, non-motor vehicles and pedestrians mixed.
At present, the facilities at the intersection are usually set as follows: 1. A crosswalk is set at the motor vehicle exit at the intersection, and a motor vehicle parking line is set behind the crosswalk. Traffic lights are set at every intersection, and vehicles in the north-south direction are released at the traffic lights. When vehicles in a certain direction are green, pedestrians in the same direction are also green. The setting and management of this traffic intersection basically does not consider the interests of pedestrians. When pedestrians cross the road, they should compete with motor vehicles turning left and right and pedestrians turning left. 2. Set a right-turn motor vehicle-only road at a sufficiently wide intersection, and set the triangle between the straight motor vehicle lane and the right-turn motor vehicle lane as a pedestrian waiting area. Although pedestrians crossing the road can avoid grabbing the road with motor vehicles, this intersection has the disadvantages of large investment, wide area, complicated road conditions, left-turning pedestrians crossing the road twice and long waiting time. Because the existing traffic light design does not treat the rights and interests of pedestrians equally, pedestrians have long ignored the authority of traffic lights.
Next, the setting will be explained by the attached drawings.

Fig. 6 is a plan view of a T-junction with four motor vehicle lanes in two directions, and traffic facilities are set when pedestrians and non-motor vehicles pass;
Fig. 7 is a plan view applied to a T-junction with four motor vehicle lanes in two directions, and traffic facilities are set when eastbound motor vehicles turn left and go straight;
Fig. 8 is a plan view applied to a T-junction with four motor vehicle lanes in two directions, and traffic facilities are set when westbound motor vehicles turn right and go straight;
Fig. 9 is a plan view of a T-junction with four motor vehicle lanes in two directions, and traffic facilities are set when southbound motor vehicles turn right and left;
In the figure 1 north-south motorway, 2 east-west motorways, 3 waiting islands for pedestrians and non-motor vehicles, 4 pedestrian command posts, 5 non-motor vehicles, 6 crosswalks, 7 crosswalk crosses, 8 pedestrian safety islands and 9 motor vehicle command lights.
Take the four-car road as an example: the road is divided into six lanes, of which two narrow non-motor vehicle lanes 5 are on both sides, four are motor vehicle lanes in the middle, and three lanes are set on the right side of the road exit, which are left-turn lane, straight lane and right-turn lane respectively, and 1 lane is set on the right side of the road entrance; Set a bend at the corner of two adjacent motor vehicle lanes, with the radius of the bend as small as possible according to the largest motor vehicle passing by, set a pedestrian waiting island 3 at the back of the bend, and set a non-motor vehicle lane 5 at the back of the pedestrian waiting island, with the radius of the non-motor vehicle lane as large as possible; Pedestrian safety island 8 is set in the center of the intersection; A crosswalk line 6 is arranged at the exit end of the motor vehicle lane; The crosswalk line 7 is arranged between the pedestrian waiting island 3 and the safety island 8; On both sides of the pedestrian waiting island 3 and the safety island 8, an isolation column with a height of about 1 m is set every 0.6 m, and a small-caliber pedestrian traffic light is set at the top of the isolation column; At the entrance of the motor vehicle lane, a large-caliber directional release motor vehicle command light is set.
The traffic at the intersection is directed by the command light, as shown below:
1. Pedestrian passage time: the traffic lights of motor vehicles in all directions are red, and motor vehicles are prohibited from passing. The small-caliber pedestrian lights on the isolation column are all green, and pedestrians can choose the shortest path to pass the intersection at will.
2. Traffic time of motor vehicles: pedestrians indicate red lights in all directions, and pedestrians are prohibited from passing;
The passage time of motor vehicles is divided into straight time and left turn time, and the straight time and right turn time allow vehicles to wait ahead as much as possible; Vehicles are allowed to turn left and right during the left turn period.
The advantages of this kind of intersection layout are:
1. Various traffic demands are not contradictory, and traffic lights have clear authority to direct traffic.
2. Make full use of the road and let pedestrians cross the intersection with the shortest path.
3. The setting of the central safety island allows pedestrians to have a stopover time when crossing the intersection obliquely, which reduces the possibility of collision between people and vehicles.
4. Less construction investment and less land occupation.
5. Low and dense isolation columns with small-caliber command lights at the top can effectively prevent pedestrians from leaning forward.
