Abstract

The need to alert drivers approaching crest vertical curves of traffic stoppages ahead led to study automatic means of detecting stoppages waves. After analyzing selected speed and energy parameters, it is concluded that both were satisfactory indicators of stoppage waves. A computer algorithm was then structured for automatic control of the warning system.
