Route 122 Airport Rotary, an intersection in Worcester, Massachusetts has experienced congestion, and with higher traffic volumes in the future, this congestion will only worsen. To address the current and foreseeable issues, a redesign of this rotary was provided to Massachusetts Department of Transportation (MassDOT). A roundabout intersection was chosen as the recommended design after evaluating collected data and using the Intersection Control Evaluation (ICE) procedure established by MassDOT. Cost estimates and manual turning movement counts were conducted. Using Synchro and Sidra software, a level-of-service analysis was performed for each potential intersection that was screened. A roundabout design offers the greatest benefit-cost when compared to other alternatives assessed.
