Abstract

The invention discloses a road corner safety speed detection and warning device, comprising: straight road, a first-speed measuring devices, a second-speed measuring devices, a warning sign, curve road, a convex mirror, a connector, an audio device, an electronic display, a support rod, and a support base. The left side of the curve road is adjacent to the straight road. The side of the straight road is sequentially provided with the first-speed measuring device, the second-speed measuring device, and the warning sign. The convex mirror is connected to the support rod through a connector below. The audio is mounted on the top left side of the electronic display. The invention also comprises a road corner safe speed detecting and warning method which comprises a baseline data acquisition step, a data screening and processing step, and a real-time alert step.

Description

technical field [0001] The invention relates to the technical field related to road curve safety, in particular to a road curve safety speed detection and warning device and method. Background technique [0002] As we all know, excessive speed before entering a corner is the main cause of accidents in corners. Speeding is one of the main causes of curve traffic accidents. According to the road traffic accident statistics of the Ministry of Public Security of China, about 40% of traffic accidents on curves are related to speeding. It is of great significance to accurately calculate the safe speed of the vehicle entering the curve and give an early warning to reduce the occurrence of traffic accidents. The traditional curve safety speed calculation method only considers the curve radius, road adhesion coefficient and other factors, and mainly focuses on the sideslip accidents of small cars, and does not consider the rollover and sideslip accidents of heavy trucks and buses o...
