Increasing Accuracy of Vehicle Speed Measurement in Congested Traffic Over Dual-Loop Sensors

Record Type: UTC

Data from loop detectors is used throughout all levels of transportation planning and traffic operation. It is almost always assumed that the data provided by detectors is accurate and reliable. This project aims to develop a suite of cost-effective tools to validate detector measurements by integrating technology with new methods of data collection. Improved loop detector measurements will enrich real time traffic control, vehicle classification, and aggregate performance measures; this feedback will assist operating agencies and policy makers to allocate resources more efficiently.
