Title:

Collection of Vehicle Speed Data using Time-Lapse Video Recording Equipment

Abstract:

This paper describes an innovative application of time-lapse video recording to assist in a highway safety improvement evaluation. The highway safety improvement is an icy curve warning system near Fredonyer Summit in northern California that activates real-time motorist warnings via extinguishable message signs, based on weather readings collected from road weather information systems. One measure of effectiveness of the project is whether motorist speed is reduced as a result of real-time warnings to drivers.
