Research on Speed Error Correction Methods for Highway Ramps
Ramp vehicle speed measurement is the core issue of ramp speed control systems.In response to the prob-lem that existing radar speed measurement can only accurately measure the speed of vehicles driving on straight and flat roads,and cannot effectively measure the speed of ramp vehicles with different slope and curvature effects,this paper studies a method for compensating for speed errors in highway ramp measurement based on binary polynomial fitting.By data fitting and calibration,the environmental characteristics of ramp roads are captured,Implement adap-tive error compensation and measurement value correction for ramp vehicle speed measurement using radar tachome-ters,and develop a ramp vehicle speed measurement system based on this method to achieve visual calibration of ramp speed values,overcoming the technical defects of existing radar tachometers that cannot effectively measure the spped of ramp vehicles.
