Vehicle Reidentification and Travel Time Measurement in Real-Time on Freeways Using the Existing Loop Detector Infrastructure

  title={Vehicle Reidentification and Travel Time Measurement in Real-Time on Freeways Using the Existing Loop Detector Infrastructure},
  author={Benjamin Coifman},
This paper presents a new methodology for measuring travel time in real-time on freeways using the existing loop detector infrastructure. The methodology uses vehicle length, a simple signature from paired loop detectors, to extract information about the traffic stream. Other methods of measuring travel time either rely on approximations from aggregate traffic parameters or use expensive, proprietary systems to extract individual vehicle signatures. The reidentification algorithm is tolerant to… CONTINUE READING
