Abstract:

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 two-sided weaving on one-way frontage roads (between an exit ramp and a downstream signalized intersection). The objectives of this study were to develop a technique for evaluating two-sided weaving operations, and to develop recommendations on minimum and desirable ramp-to-intersection 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 based upon frontage road density between the exit ramp and downstream intersection: unconstrained (density < 40 veh/km/ln), constrained (density from 40 - 100 veh/km/ln), and undesirable (density > 100 veh/km/ln). Recommended ramp-to-intersection spacings were developed based on frontage road volume, exit ramp volume, and percent exit ramp vehicles making a two-sided weaving maneuver.
