Abstract
An onboard vehicle detection system for detecting roadway items of interest. The vehicle detection system includes a central controller and a detection system connectable to the vehicle and operably coupled to the central controller. The detection system outputs a detection signal. A target device is connectable to the roadway item of interest and configured to receive the detection signal from the detection system and output a unique return signal to the detection system. The detection system receives the return signal and transfers the return signal for processing to the central controller, whereby the central controller identifies the roadway item of interest and determines a responsive action.
