In this paper, we present a new high-precision speedometer for vehicles using a K-band Doppler technology. The concept of our new speedometer is based on the Doppler effects phenomenon to obtain a speed of the vehicle more precisely. The experimental design, data collection and data evaluations are discussed, and the features of the new system have been appraised and compared with a conventional speedometer. The results show that our new speedometer development exhibits a phenomenal performance gains with low cost design, light weight and its performance provides a pragmatic element for emerging ITS infrastructure.
