A statistical algorithm for estimating speed from single loop volume and occupancy measurements

Author

  • Dailey, D. J.

Abstract

This paper presents an algorithm for estimating mean traffic speed using volume and occupancy data from a single inductance loop. The algorithm is based on the statistics of the measurements obtained from a traffic management system. The algorithm produces an estimate of speed and provides a reliability test for the speed estimate.
