Problems solved by technology
As a result, vehicles often do not pass at a constant speed when passing a sharp turning road section, but with a certain acceleration (acceleration or deceleration), which leads to a large error in calculating the meeting time based on the speed and distance between vehicles. Stop correction will also cause large changes in the calculation results, and it is difficult to give the driver a reliable warning

Embodiment Construction
[0070] Such as Figure 1 to Figure 3 As shown, the sharp-turning road section with an early warning function of the present invention includes curve section 1, which is a two-way lane, and two-way lanes include A-direction lane 2 and B-direction lane 3 with opposite driving directions. The dividing line of the two-way lane is Road center line 4;
[0071] A-direction lane 2 and B-direction lane 3 have an entry end and an exit end respectively. Each entry end is connected with an entry section 5, and each exit end is connected with an exit section 6; A lane 2 is connected to it Turning section 5 forms the A-direction passage, and the turning section 5 connected to the B-direction lane 3 forms the B-direction passage;
[0072] The length of each curved road section 5 is greater than or equal to 100 meters and less than or equal to 300 meters; A-direction speed measurement mechanisms are evenly spaced on the side of the A-direction channel, and several B-direction speed measurement me...

Abstract
The invention discloses a sharp turn road section with an early warning function. The sharp turn road section comprises a curve section, and the curve section comprises an A-direction lane and a B-direction lane; a plurality of A-direction speed measuring mechanisms are uniformly arranged on one side of the A-direction channel at intervals, and a plurality of B-direction speed measuring mechanismsare uniformly arranged on one side of the B-direction channel at intervals; the A-direction meeting reminding mechanism comprises an A-direction electric control device, and the A-direction electriccontrol device is connected with an A-direction display screen and an A-direction wireless communication module; the A-direction display screen is positioned 2-5m in front of the A-direction speed measuring device; the A-direction speed measuring device is connected with the A-direction electric control device; number information of the A-direction speed measuring mechanisms where the A-directionelectric control devices are located and road center line length information between the A-direction mounting rods of the A-direction speed measuring mechanisms where the A-direction electric controldevices are located and the B-direction mounting rods of the B-direction speed measuring mechanisms where the A-direction electric control devices are located are pre-stored in the A-direction electric control devices. The invention further discloses a corresponding meeting early warning method. According to the invention, more reliable meeting early warning can be provided for drivers with lowercost, and the safety of curve passage is improved.
Description
Technical field [0001] The invention relates to the technical field of road safety, in particular to a sharp turning section. Background technique [0002] The road traffic system is a dynamic and open system, and its safety is restricted by the internal factors of the system, and also interfered by the external environment of the system, and is closely related to factors such as people, vehicles and road environment. Unreliability, imbalance or instability of any factor in the system may lead to conflicts and contradictions, resulting in unsafe factors or unsafe states. [0003] The centripetal force required by the vehicle when passing a sharp turn is provided by the friction force of the tire against the ground. The calculation formula of the required centripetal force is: F=mv 2 / r; Among them, F is the centripetal force required when the vehicle turns, v is the speed of the vehicle through the sharp turn section; r is the radius of the sharp turn section. It can be seen that ...
