The developed procedure is based on the arterial analysis chapter of the Highway Capacity Manual and includes consideration of the delays that are incurred at ramp junctions. To develop the level-of-service analysis procedure, data were collected at several locations within Texas. Travel time, volume, and access density data were collected at 20 one-way frontage road sites and nine two-way frontage road sites. Delay data were collected at six ramp junctions. The results showed that signalized intersections have the greatest impact on the operations along a frontage road. Access density (i.e., the number of driveways and unsignalized intersections per km) affects the operations along a frontage road segment when greater than 20 acs/km on one-way frontage roads and greater than 16 acs/km on two-way frontage roads. The developed procedure produced reasonable results when compared to the average speed measured at six one-way and six two-way frontage road sites. Predicted results were generally within 3 km/in of measured speeds.
