Increasing Accuracy of Vehicle Detection from Conventional Vehicle Detectors – Counts, Speeds, Classification, and Travel Time

Record Type: UTC

The ultimate objective of this study is to develop techniques that will improve the measurement accuracy of a given detector station both at the time of installation and throughout its working lifetime. Until recently it has been difficult to validate the detector measurements, but the research team has developed a suite of tools that will greatly facilitate such validation. These improved measurements will in turn improve real time traffic control (e.g., ramp metering and traveler information), vehicle classification, and aggregate performance measures from the vehicle detector infrastructure.
