| 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 reidentification of these vehicles as sample probes passing over sequential inductive loop sensors. | |
| Goals: | Evaluate whether it is possible to enhance 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 an accurate estimate 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. | |
