SMALL & LARGE Roundabout Counts

Our Video Roundabout Count Report totals the turning movement volume (TMV) of a roundabout, detailing the entry, circulating and exit flow rate for each roundabout leg, from origin to destination & by FHWA classification groups. This data can be used to determine the capacity and performance efficiency of the different roundabout approaches, and the roundabout as a whole.


Raw data from a multi-camera roundabout follows the 5/95 rule. Turning movement data is estimated by proprietary algorithm, and suitable for input into simulation modeling software.
