Abstract:  In this webinar, we present findings from a STRIDE-sponsored research study that evaluated four alternative temporary traffic control options in work zones.The purpose of the research was to study alternative bottleneck merge control strategies with a potential to minimize congestion at interstates work zones and improve relevant construction practices.  We first introduce the current state-of-the-practice within State Departments of Transportation (DOTs). Next, we discuss the development and testing of temporary traffic control options in work zones and present the impacts of various work zone configurations and traffic control options on level-of-service, emissions, and travel time reliability. We also discuss a novel approach for performance-based work zone scheduling. This can be used as a decision-support tool by State DOTs and practitioners when choosing a traffic control strategy and time of day to setup work zones at interstate highways.


FREE!  However, there will be a $25 charge, if you are interested in receiving 1 PDH.
