Are there any traffic lights on the highway?
There are traffic lights on expressways in some cities, such as the Humen Bridge in Guangdong. Humen Bridge is the main expressway leading to Hong Kong and Macao in many cities in the Pearl River Delta, and it is also one of the most congested expressway bridges in China. On February 1, 2018, Humen Bridge used red and green traffic lights in both directions during the rush hour of traffic flow to manage the order of vehicle traffic. Three points will be scored and 200 yuan will be fined for violations, which is the first time that traffic lights are used on the main highway in China. There are two signal lights in Humen Bridge section, one is the junction point between the main line and entrance B of Nansha Toll Station in the direction of Dongguan, and the other is the junction point between the riverside expressway and Humen Bridge in the direction of Guangzhou. By enabling traffic lights during peak hours, implementing diversion release and closing the entrance, it can reduce the long meeting time and collision accidents between the traffic flow at the merging point and the traffic flow on the main line due to road grabbing, improve the traffic efficiency and alleviate the problem of high-speed congestion at Humen Bridge during the Spring Festival. Is this easy to understand?
