摘要: Nearly all of South Dakotas road closure gates were installed in the early 1980's and few modifications have occurred to the gates since the original installations. This study examined possible changes to South Dakota road closure gates, including ways that automated features might be incorporated to make intended functionality more amenable. The ultimate goals of the project were to improve road closure gate operations and minimize the safety concerns for SDDOT maintenance personnel at road closure sites. The study required an overall assessment of road closure sites around the state to determine the performance issues surrounding existing gate configurations. The study then proceeded to relate what types of modifications might be warranted at each of the various sites, along with an assessment as to the extents that automation might be introduced. Reviews of literature focusing on state-of-the-art road closure equipment, various methodologies to perform road closures, and the dictates that frame the performance of road closures resulted in the accumulation of a variety of material on the subject. The research efforts to perform detailed assessments of road closure sites on a statewide basis were performed through in-depth surveys of maintenance personnel at SDDOT Area Offices. Other information was gathered through on-site visits to road closure locations both in-, and out of the state. To facilitate the analysis efforts of the automated aspects, an actual installation of electrically actuated droparm style gates was performed for testing and evaluation purposes. The test installation was meant to evaluate the reliability of the design, mechanical, and operational characteristics of this type gate in comparison to similar characteristics found in South Dakotas existing swing-type gates. The investigations of South Dakotas existing road closure gate systems and their functional performance led to conclusions that the currently used gates do need to be replaced.
