| Work zone congestion mitigation strategies are utilized by transportation agencies to reduce or eliminate congestion through a work zone as part of the project's Transportation Management Plan (TMP). The objective of this research is to assist agencies' strategy selection by identifying strategies used by State Transportation Agencies (STAs) nationwide and their experiences. A survey was developed to focus on STAs' current strategy implementation, past implementation, and future strategy research and objectives. STA respondents were asked questions concerning strategy implementation for projects similar to four developed scenarios: rural reconstruction, rural resurfacing, urban reconstruction and urban resurfacing projects. Other areas investigated include agency utilization of work zone traffic analysis tools and work zone lane capacity values. The culmination of the survey analysis consists of recommendations for future research and strategy selection tables displaying the analysis results for TMP strategy combination development. The survey received 42 responses, encompassing at least 28 states. |
