16. Abstract
Commercially available instruments for road-side data collection take highly limited measurements, require extensive manual input, or
are too expensive for widespread use. However, inexpensive computer vision techniques for digital video analysis can be applied to
automate the monitoring of driver, vehicle, and pedestrian behaviors. These techniques can measure safety-related variables that cannot
be easily measured using existing sensors. The use of these techniques will lead to an improved understanding of the decisions made by
drivers at intersections. These automated techniques allow the collection of large amounts of safety-related data in a relatively short
amount of time. There is a need to develop an easily deployable system to utilize these new techniques.
This project implemented and tested a digital video analysis system for use at intersections. A prototype video recording system was
developed for field deployment. A computer interface was implemented and served to simplify and automate the data analysis and the
data review process. Driver behavior was measured at urban and rural non-signalized intersections. Recorded digital video was
analyzed and used to test the system.
