The first pressure sensor 1 and the fourth pressure sensor 5 are respectively arranged below the road surface of a front right lane at the entrance of two ends of the curve and are used for detecting the information of coming vehicles which are about to enter the curve; the second pressure sensor 2 and the third pressure sensor 4 are respectively arranged below the road surface of the left lane at the exit of the two ends of the curve and used for detecting the information of the vehicle running out of the curve; further, in a specific embodiment, the first pressure sensor 1, the second pressure sensor 2, the third pressure sensor 4, and the fourth pressure sensor 5 are MPM4700 type pressure sensors.

The first display screen 3 and the second display screen 6 are respectively arranged at the entrance of the curve and face the incoming direction for displaying the information of the opposite vehicles.

For the road with sharp turns in the mountainous area, the road with sharp turns can be narrowed, and only one lane is arranged at the sharp turns in order to ensure safe passing. For easy understanding, as shown in fig. 1, the two ends of the sharp bend are divided into an ascending part and a descending part, and lane change lines are arranged at the positions where the entrances of the two ends of the sharp bend are narrowed. The lane changing lines are divided into an up-changing line and a down-changing line according to the form direction of an up-going vehicle and a down-changing line, wherein the up-changing line comprises a first up-changing line 9 and a second up-changing line 10, and the down-changing line comprises a first down-changing line 11 and a second down-changing line 12. Along each lane change line, the LED floor lamps 8 are uniformly arranged, as shown in fig. 2.
