Project detail
Project Description:   Phase II: Utilize loop amplifier electronics to analyze duration of pulses from existing inductive loops at a higher frequency to identify unique vehicles and facilitate identification and re-identification of these vehicles as sample probes passing over sequential inductive loop sensors.
Goals:   Evaluate whether it is possible to enhanced existing loop sensor amplifiers to measure and track a subset of vehicles to create anonymous travel time and origin-destination information for a subset of the vehicle population.
Background Information:   The purpose of this project is to develop a tool for measuring traffic system performance for arterials, network and corridor management systems.
Test Methodology:   See project description.
Partners:   U.S. Department of Transportation: Research and Innovative Technology Administration (RITA); Role(s): Other stakeholder
Expected Benefits:   The expected benefit is the development of new techniques for measuring system performance.
Project Findings:   Phase I demonstrated that it was possible to create a accurate estimates of travel times over short lengths. Phase I also found software changes that have to be made to controller algorithms to allow sampling of the data.
