With the development of society, the number of private cars is also showing an obvious growth trend. In order to relieve traffic pressure, we will install LED traffic lights at various intersections. So how many signal lights are reasonable to install at intersections? Next, let the editor take everyone to study it together:
1. When there is a left-turn waiting area at an under-bridge intersection or a larger level intersection, and when it is difficult for vehicles entering the left-turn waiting area to observe the change of the oncoming signal light, we need to turn left and wait An LED traffic signal light group with a left-turn arrow is added to the opposite side of the turning area.
2. When a correctly channelized triangular diversion island is set at the intersection, the signal lamp post should also be usually set on the diversion island.
3. If it corresponds to an entrance of an intersection, we can install one or more road traffic signal light groups as needed.
4. For roads without motor vehicle lanes and non-motor vehicle lanes, the poles of LED traffic lights are best installed at the curb tangent point attachment; when the road is wide, it can be cantilevered on the sidewalk on the right side of the road. superior.
5. When the distance between the imported stop line and the opposite signal lamp is large, we can choose the LED traffic signal lamp with the transparent surface size of the light-emitting unit of 400mm in diameter.
6. If there is a secondary stop line under the overpass, a signal light group should be added on the other side of the overpass.
7. Generally speaking, when the width of the isolation belt allows, we can install the opposite signal light pole within 2m behind the tangent point of the edge of the non-isolation belt; when the road is wide, it can be cantilever installed on the road. The right side isolation belt, of course, we can also add a signal light group in the left side machine non-isolation belt as needed; when the road is narrow, we can use column installation in the isolation belt on both sides of the road; pay attention to if the isolation belt If the width is small, the LED traffic light pole cannot be installed.
The above is the relevant content about the number of LED traffic lights installed. We all know that although the installation of road traffic lights can relieve our traffic pressure, it is not that the greater the number of installations, the better. We should follow the traffic flow at the intersection and Carry out a specific analysis of the sight situation, and calculate the most reasonable installation quantity based on this, which will benefit our society.
