Traffic Monitoring and Estimating Speed by Side-Looking FMCW Radar

One of the most important problems in traffic management is evaluating the amount of traffic and the velocity of vehicles passing through transportation ways and main streets. In this study, the traffic load is measured, and the speed of cars is estimated using the 24 GHz FMCW radar. In this process, an antenna is installed to record all the targets from the side of the highway. Next, the moving vehicles are classified according to their type, based on which the traffic load is provided to the user in each highway lane. Due to the radial velocity, low Doppler frequency, and variability with time, some challenges will emerge, for which two solutions will be provided. This paper describes the speed of cars and the amount of congestion in each highway lane presented by two new methods. Finally, with the process of canceling clutters observed by radar and detecting possible errors, a highway statistic is presented as a table.
