Traffic Smoothness Improvement Action
In order to actively respond to the traffic hotspots concerned by the people and ensure the smooth travel of the masses, the Kunming public security traffic police conducted field research on the intersections with unstable periodical and directional needs for traffic operation in the main urban area, and in accordance with the principle of "one policy all the way, one policy for one mouth", the "variable guide lane" traffic organization measures will be taken at some intersections to improve the traffic efficiency of the intersection with embroidery efforts, further alleviate road traffic congestion, improve road traffic efficiency, and create a safe and orderly road traffic environment for the masses.
Intersection of this phase: the intersection of Beijing Road and South Huancheng Road
“
Overview of the current situation
The intersection of Beijing Road and South Huancheng Road is an important traffic conversion hub in the central urban area, of which Beijing Road is an important traffic artery connecting the main urban area and the northern urban area, South Huancheng Road is an important part of the ring road network, the south side of the intersection is Kunming Railway Station, the vehicles come and go frequently, the traffic pressure in the morning and evening rush hour is greater, and there are Kunming Rail Line 1 and 2 transfer stations near the intersection at the same time, and the flow of people is intensive.

Vehicle queue length
The straight right lane of the outermost side of the north entrance, because the right-turning vehicle is interfered by the straight-going vehicle, the traffic efficiency is not high, and secondly, the right-turn efficiency is further reduced by the influence of non-motorized vehicles and pedestrians crossing the street, and the queue length is longer;

In the current road conditions do not have the ability to increase the lane, in order to fully tap the space and time resources of the intersection, reduce the interference between straight and right-turning vehicles, and maximize the efficiency of the intersection, the Kunming public security traffic police will be the first to pilot the implementation of the "embedded waiting variable guide lane" at the north entrance of the intersection.
What is the difference between an inline stand-by variable guide lane?
The embedded waiting lane is to adjust the outermost straight right lane to a variable lane, and add LED lane signs that can go straight and turn right. At the same time, an independent right-turn vehicle stop line is set up at a position about 50 meters behind the intersection stop line, and a motor vehicle right-turn signal light and related reminder signs are added.
How do you get through the inline waiting change lane?
The signal phase at the intersection of Beijing Road and South Huancheng Road is the standard four-phase release of straight and left first.
Phase 1: Straight north-south traffic
1. Right-turning vehicles wait at the right-turn stop line, at this time the right turn is a red light, the LED lane sign shows going straight, and the straight-going vehicle can pass through the variable lane;
2. When the green light for straight traffic is about to end, the green light for turning right will be on, and the LED lane sign will show that it will turn right, and the right-turning vehicle can pass through the variable lane;
Phase 2: Turn left from north to south
Turn right at a green light, LED lane signs show right turns, and right-turning vehicles can pass through the variable lane.
Phase 3: Straight east-west traffic
Turn right at a green light, LED lane signs show right turns, and right-turning vehicles can pass through the variable lane.
Phase 4: Turn left from east to west
1. Turn right at a green light, LED lane signs show as a right turn, and right-turning vehicles can pass through the variable lane;
Second, the east and west left turn green light is about to end, when the north and south straight green light is about to open, turn right to the red light, the LED display screen is straight, at this time the right-turning vehicle is forbidden to enter the variable lane, wait for traffic in the rear stop line, and the straight vehicle can drive into the variable lane and wait for traffic.
Tips
The intersection will be renovated in the near future
After the renovation is completed
Members of the public are advised to pay attention to the intersection when passing by
Follow the prevailing rules
and intersection signal lights and signs to indicate traffic
