U. S. 61 Muscatine Bypass Corridor

This report was prepared for the Iowa Department of Transportation to document the results of a comprehensive study of the US 61 bypass corridor in Muscatine, Iowa. The focus of the study was to address community concerns regarding traffic safety and traffic operations. In completing the study, accident and traffic volume data was collected and analyzed. Input from the public and elected officials of the Muscatine community was also obtained. The goals of the project were to: Accurately identify the nature of the types of problems and the locations where the problems were occurring; Formulate a range of possible remedial measures; Analyze and test those proposed measures; Inform the community of the nature of the traffic problems and of the proposed remedies; Seek feedback from the community on those proposed remedies; Develop a comprehensive list of recommended improvements; Develop cost estimates and assign priorities to those possible improvements. An additional goal of this project was to identify possible Intelligent Transportation System (ITS) measures that could be used to address the safety and operations problems that have developed along this corridor. The proposed ITS measures were also to be analyzed to determine their likely benefits and their likely success if used at other locations elsewhere in Iowa.
