Develop Guidance for Enhancing Work Zone Safety in the Construction of Innovative Intersections
Innovative intersections, also referred to as alternative or unconventional intersections, are essential for enhancing traffic flow and safety. In Texas, there has been a significant increase in the construction of innovative intersection designs such as diverging diamond interchanges (DDIs), median U-turns (MUTs), and reduced conflict intersections (RCIs). However, they present notable challenges during construction. A primary concern associated with implementing these designs is maintaining traffic flow during construction to minimize disruptions and ensure safety. The geometric configurations of these intersections introduce complexities that are not addressed by previous guidelines, posing safety risks for motorists and workers. The absence of standardized specifications for work staging and risk mitigation strategies in work zones exacerbates these issues. Using a mixed-method approach, the research team will identify safety risks intrinsic to the construction of innovative intersections and temporary traffic control (TTC) measures that can eliminate or reduce these risks. The research team will develop comprehensive guidance for developing and implementing TTC strategies for innovative intersections. The documentation and evaluation of these strategies will establish a comprehensive framework for safely and effectively implementing innovative intersection designs in Texas, catering to the specific needs of drivers, including seniors and teenagers.
