Time-of-Day Traffic Volumes Using Video Imagery Obtained from Transit Buses in Regular Operations

Transit agencies are increasingly equipping their fleet with video cameras for safety, security, and liability purposes. We propose that the existing video imagery on transit buses can lead to traffic volume estimates on the roadways traversed by the transit fleet at minimal additional cost. Unlike traditional approaches, which collect data at a few fixed locations on an urban network, transit buses cover most major roads across the urban network on a regular, repeated basis. Although any one passage of a bus over a road segment would lead to a very short duration, “noisy” estimate of traffic volume, the repeated coverage of transit buses should allow a sufficiently large number of independent observations that good estimates of traffic volume patterns could be obtained.

We present empirical results that compare time-of-day traffic volumes estimated using video imagery obtained from transit buses during their normal operations to traffic volumes obtained from concurrently collected road-tube data. The comparisons indicate the potential of using existing data at minimal additional cost for ongoing traffic volume estimation over large geographic regions on an ongoing basis. .
