- Description
- Contributors to traffic safety hazards include lane changes in the presence of queues at signalized intersections and bus stops, mixes of vehicle classes, speed variability, and vehicle overtaking. Traditional data collection methods that are constrained in time and space are prone to biased sampling. Taking advantage of video imagery recorded by transit bus-mounted cameras for other purposes offers an opportunity to overcome this bias. In this project the available, repeated, and extensive imagery recorded by such cameras for identifying queue presence and length related safety hazards is investigated. The increased presence of queues in association with construction zones is also explored. The campus of The Ohio State University roadway network is used as a living lab testbed. The results demonstrate the feasibility of the approach in identifying queuing over space, including around construction zones, and time. Further improvements and extensions are discussed.
