Abstract:

This report documents the findings of a detailed study of freeway frontage road operation and safety. Vehicles were videotaped during the exit and entry maneuver to and from frontage roads for all types of ramps. Erratic maneuvers were identified and recorded. The master file of the Department of Public Safety accident file was searched and accidents occurring in the ramp areas identified. The report documents the types of erratic maneuvers observed and the recommended treatments to reduce the number of erratic traffic movements in ramp areas. There was no apparent pattern to erratic maneuvers except that slip ramps to one-way frontage roads had the largest percentage of these maneuvers. The accident analysis revealed that ramp type was not a significant contributor to accident experience at the ramp-frontage road intersection. Frontage road ADT and degree of roadside development were found to be significant.
