Description
Inductive loop detectors positioned along the Portland, Oregon Metropolitan Area Freeway System collect and report fundamental traffic measurements, namely, speed, occupancy, and volume. These measurements are archived in the PORTAL ADUS, and they are of great interest for several public and private entities, such as the Oregon Department of Transportation. Loop detectors remain the most widely used mechanism to measure traffic data, yet, they are subject to a number of conditions that severely harm data quality and availability. We are looking at ways to catch and fix erroneous (or incomplete) data streams coming in from the sensors, hoping to impute them near real time so that final products (such as speedmaps) have as much useful information as possible.
