This report is part of a larger study developing a level of service evaluation procedure for freeway frontage roads. The results from this report will aid engineers in evaluating existing and proposed two-sided weaving sections on one-way frontage roads. The procedures developed can be used to estimate the level of service at these types of sections. This, in turn, will aid engineers in prioritizing frontage road improvement projects and/or predicting future operations. Also provided are recommended desirable and minimum exit ramp-to-intersection spacings. The results from this study will be incorporated into the final frontage road analysis package.

Over the past few years, there have been many studies concerning the effects of weaving on freeway operations; however, there have been few attempts to study the effects of weaving at "non-freeway" sites, such as freeway frontage roads. As part of a larger study that is developing a level of service evaluation procedure for freeway frontage roads, this report addresses the issues associated with one-sided weaving on one-way frontage roads. The objectives of this study were to develop a technique for evaluating one-sided weaving operations, and to develop recommendations on minimum and desirable ramp spacing. To meet these objectives, both field data and computer simulation were used. From the results of this study, the following three levels of service were defined: unconstrained (weaving volume 1500 vph), constrained (weaving volume from 1500 - 3000 vph), and undesirable (weaving volume 3000 vph). Concerning ramp spacing, the results revealed that it is desirable to have a weaving length greater than 300 meters with a minimium value of 200 meters

The research project examined certain effects of converting the Interstate 30 (I-30) frontage roads in the central Arkansas area from two-way operation to one-way operation in 2002. The following characteristics before and after the conversion were studied: the number of crashes; traffic volumes; speeds; travel times between nodes; land use; sales taxes for certain businesses; and the opinions of business owners and operators in the corridor.

The main objectives of this study were to develop procedures for estimating the level of service on freeway frontage roads and to determine desirable spacings for ramp junctions. The tasks involved developing (1) procedures for analyzing frontage road weaving sections, (2) recommended spacing requirements for ramp junctions, and (3) a technique to evaluate overall operations on a continuous frontage road section. The two weaving segments analyzed included a one-sided weaving area formed by an exit ramp followed by an entrance ramp and connected by an auxiliary lane and a two-sided weaving area formed by an exit ramp followed by a downstream signalized intersection.

The objective of the research was to develop a procedure for evaluating the operations along one-way and twoway freeway frontage roads. 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.
