Use of Video Analytics for Turning Movement Counts

Turning Movement Counts (TMC) are certainly the most common studies done at intersections. Turning movement counts are used for coverage counts, warrant studies, and for input for signal timing software. The traditional method to perform TMC is manual use of a Jamar count board. This results in a relatively large variability in the traffic counts at a given intersection from day to day, week to week etc. In addition, the cost of performing manual counts prohibits extensive and frequent counts. This paper describes different methods to automate turning movement counts using modern video detection technology. Whereas one method is evolutionary, using video detection equipment that may have been deployed for stop bar presence detection, a more revolutionary approach makes use of recent developments in video processing to use regular closed circuit television (CCTV) feeds from an intersection without the need of any additional field hardware.
