Abstract

A Kinematic Wave Model For Merge Queuing Daiheng N I School of Civil and Environmental Engineering, Georgia Institute of Technology Atlanta, GA 30332, USA and John D. L EONARD State Road and Toll way Authority. 101 Marietta Street, Suite 2500 Atlanta, GA 30 303 , USA A BSTRACT Queuing at a merge is of particular interest because it is often related to highway congestion. Kinematic waves models such as simplified theory of kinematic waves are welcomed by traffic engineers because these models are simple and efficient yet still provide sufficient measures of effectiveness (MOEs) without going into the low level details of individual vehicle behavior. However, the original simplified theory deals only with freeway mainline and it would be of great interest to b oth theory and practice if this simple and elegant algorithm can be extended to address network traffic. As part of such effort, this paper deals with simplified kinematic waves at a merge. Several merge models are reviewed and a capacity - based weighted fa ir queuing (CBWFQ) merge model is proposed. This merge model exhibits several attractive features which make it ideal for modeling merge queuing in terms of simplified theory of kinematic waves.
