Abstract:Complete benefits and impacts of innovative intersection and interchange designs are still unclear. There is a lack of methodologies for a quick estimation of these designs for various transportation modes (vehicular traffic, transit, bicyclists and pedestrians), as well as the access management. This study aims to answers those questions. The study integrated multiple available methodologies for evaluating innovative designs with those specifically developed during this research. Two main modules, operational (including access management) for different transportation modes and safety, were the main focus. The study used test-case sites from the state of Utah to develop and test the modules. A combination of field assessment, microsimulation and crash data analysis was implemented to develop and calibrate specific methodologies. The modules were implemented in a user-friendly Excel model.
