TRAVEL TIME ESTIMATION USING CROSS CORRELATION TECHNIQUES. FINAL REPORT

This project demonstrates the viability of using cross-correlation techniques with inductance loop data to measure the propagation time of traffic. The propagation time between loops separated by 0.5 miles is measured using time averaged activation counts ("Volume") from inductance loops. The resulting time delay is used to estimate the mean speed. This independent speed estimate is used to improve the Volume/Occupancy ratio estimate of speed. A functional form relating speed to the Volume/Occupancy ratio is developed and evaluated using real traffic data. This result can be used to improve the total travel time estimates for commuters in the I5 corridor in Seattle, Washington.
