ESTIMATING DENSITY AND LANE INFLOW ON A FREEWAY SEGMENT

This paper presents density estimation and lane inflow measurement techniques for a freeway lane between two detector stations. The study uses vehicle arrivals at each detector station and information from a vehicle reidentification system that only matches a small portion of the passing vehicles. This methodology needs only accurate matches rather than a high frequency of them. For vehicles that are reidentified, their travel time is the difference between their arrival times at each station. The measured travel time allows for density estimation and upstream offset that allows for lane inflow measurement. Examples are given that illustrate that it is possible to capture the net effect of vehicle maneuvers in space using loop detectors as fixed points. The methodology is potentially applicable to other technologies as well.
