Calibrating and "Fixing" Roadway Detectors Using the Caltrans VideoSync System

Caltrans has developed a comprehensive system to evaluate, calibrate, validate, and "fix" loop detectors, radar systems, and other types of roadway surveillance stations. This system is called VideoSync. VideoSync consists of an array of video, graphical, and statistical analysis tools in an integrated software package optimized for traffic detector assessment; along with an optional adjunct set of field hardware to aid in data collection. Being a turnkey system, VideoSync is best used for real time detector site calibration, and contains all the facilities necessary for a complete end-to-end system check before leaving the field site. However, VideoSync also stores all data for more detailed post processing offsite, or simply as proof of validation. The VideoSync system contains more sophisticated "ground truth" validation capabilities than many of the more expensive evaluation sites set up specifically for comparative detector evaluations, only VideoSync can be set up and used anywhere.
