Validating Traffic Flow-detectors using Manual Counting from Video Data

According to Las Vegas' Freeway and Arterial System of Transportation (FAST)/Nevada Department of Transportation (NDOT) inter-local agreement for the freeway management system (FMS) scope of service, traffic volumes from Freeway Flow Detectors (FDD) need to be compared and verified. The total lane-by-lane traffic counts need to be verified to assure that the FDDs are properly aligned and calibrated. The scope of work for this project outlined tasks for the implementation of traffic count verification for the freeway flow detectors on segments of I-15, US-95 and CC 215. FAST provided traffic counts and corresponding videos of traffic flow extracted from the FMS database and freeway surveillance videos of the same time periods and locations to be verified. University of Nevada, Las Vegas, Transportation Research Center, verified the traffic counts (lane-by-lane) from the videos. Data analysis was performed on the traffic counts, and this report was generated to document the verification results.
