8 صفحه - PDF New Methods for Determining Capacity of Bottlenecks on FreewaysRahim F. Benekohal - Professor of Civil and Environmental Engineering University of Illinois at Urbana-ChampaignHani Ramezani - Graduate Research Assistant University of Illinois at Urbana-Champaign چکیده مقاله:Accurate determination of capacity of bottlenecks is essential for proper traffic management in and around bottlenecks. Restrictions in roadway geometry or traffic composition, or implementation of new operational policies may create a chock-point on a freeway. Regardless of the cause of bottleneck, the effects are often congestion, queue, and increase in travel time. Bottlenecks may also create unsafe driving conditions and may increase the chance of rear-end collisions. This paper presents two new method ...
