The traffic light problem belongs to the traffic police department. You can solve it with them. For example, it is suggested to change the left and right lanes adjacent to the through lane to the left+through lane and the right+through lane, or to extend a through lane at the traffic lights. There is a lot of traffic, but the traffic light is only 15 ~ 20 seconds, so there are not many cars at a time, and the traffic jam is very serious at night rush hour.
Then, according to the preliminary investigation, the traffic police department optimized the traffic organization at the intersection of Qimashan Road and Xishan Road as a whole, and set up a screen display waiting area for the east-west two-way left-turn lane and the north-south straight lane, which improved the traffic efficiency of the intersection and optimized the signal timing scheme at the intersection. They will also conduct research step by step and make timely adjustments according to the overall situation of the intersection.
