  title={Design of Velocity-Measuring System with Doppler Radar Concept and FFT Algorithm Based On ARM Processor for Traffic Safety},
  author={T. Phani and S. Sridevi},
The real-time monitoring of vehicles velocity has become essential for traffic safety. Since Traffic control is one of the largest challenges in cities and metros. Therefore, in turn to improve the method of monitoring the velocity of vehicles on road, this paper has designed a new radar based velocity measuring system which is based on ARM processor. This system uses the Doppler principle and spectral estimation FFT algorithm, in its hardware design part, and it takes full use of the… Expand
