DRIVER COMPREHENSION OF FORMATS FOR PRESENTING TRAFFIC INFORMATION ON DYNAMIC SIGNS

This report describes the Drive Time system which was begun in July 1995 on Melbourne's South Eastern Arterial to provide drivers with information about traffic conditions and incidents on the arterial. Before installation of the Drive Time system, driver comprehension of various possible formats for the Trip Information Signs was investigated. Formats investigated included vehicle speeds, travel times and descriptive labels. Color coding of the signs was also studied to see if it would result in improved comprehension of the information presented.
