Abstract:New and emerging transportation technologies, driven by automation, connectivity, and electrification, could potentially help address the transportation sector’s persistent and pervasive problems associated with safety, mobility, energy use, and so on. For this reason, the state of Indiana, uniquely positioned to serve nationwide interstate truck traffic, seeks ways to identify and incorporate these new technologies on Indiana’s highways. This report addressed the challenges and opportunities regarding the integration of transformative technologies in Indiana’s truck operations, with particular focus on truck platooning. The report started with a review of current literature about disruptive technologies in general and truck platooning. This includes published information on the impacts of platooning on transportation outcomes—energy use, mobility, safety, truck operators’ comfort, infrastructure condition/longevity, emissions, and other impacts. Regarding these impacts, the report summarizes existing simulation models for analyzing/evaluating truck platooning. Driver comfort, in terms of the platoon inter-truck headways, was investigated using a driving simulation study at Purdue University’s Center for Connected and Automated Transportation Center (CCAT) Human Factors Laboratory. The report also identified and discussed opportunities and challenges to truck platooning. Next, the report presents a process developed for identifying truck-platooning sections, and a multi-criteria framework for ex poste or ex ante evaluation of platooning segments. Finally, the report discusses the future trends of freight transportation in Indiana (including the challenges and opportunities) in truck platooning policy and development.
