Why is the Guangdong section of Guangxu Expressway prone to traffic jams during rush hours, while the Hunan section is smooth?

It is the first-class highway of Qinglian in the 1990s, with a speed limit of 100, another name for the guardrail. If the speed limit of the car is 120 at this high speed, the congestion time may be reduced. I started running this road from the original Qinglian Wanbu Road, and now I have basically been to Guangzhou and Guangdong. Thanks to Shenzhen Expressway for repairing Qinglian Expressway. The main reason is that the traffic volume is too large and the speed limit is low, such as Baishugong Tunnel 80, which causes traffic jams. Cars passing through Hunan from Hubei are used to taking Beijing-Guangzhou Expressway instead of Xuguang Expressway, so the Hunan section of Beijing-Guangzhou Expressway is very congested, while Xuguang Expressway is very smooth. After cars enter Guangdong, they are used to taking Xu-Guang Expressway, and seldom take Beijing-Guangzhou Expressway. Therefore, the main reason for the Beijing-Guangzhou high-speed train in Guangdong is that it cannot enter the fresh service area. The car slowed down and wanted to enter the service area. If it couldn't get in, the car behind it was also blocked. The more cars there are, the longer the traffic will be, and there is little traffic jam every time I go home.

Xuguang speed limit is 60-90. The road surface is poor, there are many mountain roads and tunnels, but the charge is cheaper than that of Guangzhou, and the distance from Lianzhou to Guangzhou is also closer than that of Guangzhou. Xu-Guang Expressway, China national expressway network number is G042 1 (original G4W2, GB/T 9 17, the speed limit is 80, and traps are everywhere, so the expressway is set up to stop in the service area! But there is such a thing! I hope I can improve in the future. From Fenghuang to Tongren, it is the same road. Guizhou is restricted 1 10, and Hunan is restricted 100. It seems that there are many caves in Guizhou. Although the gap is only 10, it reflects the backwardness and complacency of expressway management in Hunan. I hope this online discussion can move Hunan.

Hunan Expressway is not only the gate of death, but also the national highway. For example, entering the high-speed section of Longshan County, Xiangxi, Hunan Province, with six lanes in both directions and a speed limit of 40. If it only exceeds 60mph, it will be fined 2000, and deducted 12 points. It seems to be a buried mine and a dug pit, which makes people hard to prevent. First, I'm from Hunan. I have been in Zhuhai for three years and have never violated the rules. I drove back to Hunan at the end of April last year. After entering Hunan, I made two violations. After nine o'clock, I still follow the navigation. After entering Hunan, the speed limit in some places is 60.
