In an effort to present the terminology, equipment and basic areas of application, this paper outlines the state-of-the-art of this traffic engineering tool and details the time lapse program in Ohio. In traffic applications, time-lapse involves filming at 1 frame per second (fps) and then viewing the film at either 4, 8, 16, or 24 fps depending on the level of analysis. The equipment is described and details are outlined of the typical film system and the typical Time-Lapse video tape system. The Ohio program is directed toward the identification of potential applications of the technique in traffic control, the evaluation of the technique, and the development of a capability to efficiently study high-hazard, safety and operational problem locations. The many areas of application described here include traffic surveillance, the documentation of known problems or the lack thereof, documentation at public hearings, as data source in an Operations Review Team, before and after studies, and special studies (eg. the effects of crash attenuator debris on adjacent traffic, and other studies).
