ALGORITHM DESIGN. In the Paired VL sensor system, the VVDC system processes video data for interval LV volume estimates. Intervals containing LVs are discarded from the speed calculations. Therefore, intervals used for calculating speed estimates with Equation (8- 1) are those containing only SVs. Because SV lengths vary narrowly around their mean, a constant g value calculated with Equation (8-2) can produce reasonably accurate speed estimates. Video and single-loop sensors that form a Paired VL sensor system must be spatially close to each other. Ideally the single-loop detector should be visible in the video camera’s field of view. Before the paired video and single-loop sensor data can be fused, the two data sequences must be time synchronized. The Paired VL sensor algorithm, therefore, contains three steps: (1) time and location synchronization between the selected single-loop sensor and the VVDC system, (2) LV interval identification, and
