ONE-SIDED WEAVING ANALYSIS ON ONE-WAY FRONTAGE ROADS. INTERIM REPORT

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 m with a minimum value of 200 m.
