[0033] The safety speed detection and warning method for road curves includes the following steps.
[0034] 1) Reference data collection step: establish a case database in the cloud server, use the detection and warning device to record the speed and image data of passing vehicles for a period of time, and the relevant data of each passing vehicle forms a vehicle entry. Items include, but are not limited to, the first speed measurement data, the second speed measurement data, the exit image, the exit speed data, the corresponding weather condition information, and the corresponding visibility information; the record lasts for at least 5 days; the above data is temporarily stored in the database server before transmission To the cloud server;
[0035] 2) Data screening and processing steps: Mark all vehicle entries in the aforementioned case database as safe, and mark the entry of vehicles that exit the curve that is safe and the exit speed does not exceed the limi...
