Ultra-high performance concrete (UHPC) overlays are beginning to be recognized as a viable solution for bridge deck preservation. To accommodate construction sequencing during installation, vertical cold joints between UHPC pours are often unavoidable. Furthermore, the formwork and detailing used at these cold-joint locations are not yet standardiz

This document highlights drivers' decisions regarding the dilemma zone (DZ). The DZ phenomenon is described as the moment when drivers face a predicament as a stoplight suddenly turns yellow, requiring either an abrupt stop or a rapid acceleration through the intersection.
The document provides the transportation operations community (public agencies, consultants, and researchers involved in planning for, designing, operating, and maintaining transportation operations and management systems) with information on practices in coordinating with information technology staff. This material focuses on the value of coordina
