1. A traffic sensor for monitoring a roadway, the traffic sensor comprising:

  • a radar system including a plurality of beams and configured to transmit signals into a roadway and to receive reflections of signals reflected off of objects in the roadway using the plurality of beams; and

    a computer system coupled with the radar system and configured to;

    detect one or more targets in the plurality of beams of the radar system;

    compute a first position for one or more detected targets for a first detection period;

    compute a second position for one or more detected targets for a second detection period;

    derive at least one filtered computed position for at least one of the one or more detected targets using the first computed position from the first detection period and the second computed position from the second detection period.
