Greetings!
In addition to the naturalistic study of driving behavior, the SHRP 2 Safety program's research also includes a site-based risk study, which focuses on vehicle trajectories at specific locations, such as intersections. Site-Based Video System Design and Development (SHRP 2 Report S2-S09-RW-1) describes the work that was done in the latter track to develop and test the Site Observer--an on-site, video-based data collection system prototype with the potential for widespread application by researchers and state and local authorities to examine intersection safety. By tracking individual vehicles through an intersection, the Site Observer prototype provides a basis not only for viewing crashes and near crashes but also for developing objective measures of intersection conflicts and collecting before-and-after data when design or operational changes are made at intersections. It also yields detailed and searchable data on the normal driving population so that exposure measures can be determined.
