The objectives of the study were to identify the safety and operational problems of ramp-frontage road intersection, terminals of one-way frontage roads; the probable effect of conversion from two-way to one-way service roads and finally, to suggest warrants for conversion from two-way to one-way frontage road operation. Data were collected at nine frontage road conversion sites, forty-five ramps, including both entrance and exit ramps, and all types of ramps used on two-way and one-way frontage roads. Erratic maneuvers were recorded and accident experience examined statistically. From these data, it was determined that ramp type was not a significant influence on the accident rate. Degree of roadside development and frontage road average daily traffic were the only statistically significant factors.
