improved traffic flow results from grade separation<\/span><\/h2>\n

situated in west-central iowa, the city of jefferson is the embodiment of a healthy and bustling rural community. however, one problem area that had troubled the community for years was the intersection of a busy, north-south arterial roadway (iowa highway 4) and the union pacific railroad train tracks near the center of town. the tracks carry nearly 70 trains per day traveling at speeds up to 70 mph. snyder & associates was tasked with performing a feasibility study to assess the practicality of constructing a grade separation at the intersection to alleviate delays and safety concerns for pedestrians and vehicles<\/a>.<\/strong><\/p>\n

quality of life improvement: grade separation lays groundwork for quite zone<\/strong><\/span><\/h2>\n

subsequent to the feasibility study, the city of jefferson pursued the establishment of a quiet zone through town. a quiet zone is an exemption to the federal railroad association rule that requires trains to sound their horns when approaching 世界杯足球比赛预选赛 highway-rail grade crossings.<\/strong> one major obstacle in establishing a quiet zone was the existing crossing between iowa highway 4 and the railroad tracks. separating those two facilities at that location was viewed as a necessary catalyst for commencing a quiet zone study and the quality of life improvement the city was looking to achieve.<\/p>\n

feasibility studies consider all challenges to provide a clear solution for railroad track & highway intersection<\/strong><\/span><\/h2>\n

the goal of the feasibility study was to evaluate the viability of the project to ensure it\u2019s technically, legally, and economically justifiable. the study also affords the opportunity to provide stakeholders with a clear picture of the proposed project. a steering committee was comprised of representatives from local businesses in the city of jefferson, greene county, the iowa dot district 1 staff, union pacific railroad, and snyder & associates.<\/p>\n

the study team faced multiple challenges in determining the optimal solution for the studied crossing.<\/strong> specific areas addressed included:<\/p>\n
