The WTI Mobile Laboratory van with integrated dual video-camera traffic monitoring systems is used to obtain 24-hour long video samples of urban and semi-urban traffic flow. A number of locations in ten Western Montana cities have been identified as candidates for implementation of this non-intrusive traffic sampling methodology, and as many of these sites as possible will be sampled during the contract period. Deliverables from WTI to MDT include time-lapse video recordings of the 24-hour sample, along with count and classification data obtained using the mobile laboratory automated software and hardware systems.
