Abstract:Automated vehicles have the potential to bring about transformative safety, mobility, energy, and environmental benefits to the surface transportation
system. They are also being introduced into a complex transportation system, where second-order impacts, such as the possibility of increased
vehicle-miles traveled, are of significant concern. Given the complexity of the impacts, a modeling framework is needed to ensure that they are
adequately captured. This report presents a framework for estimating the potential benefits and dis-benefits of technologies contributing to the
automation of the Nation’s surface transportation system. Components of the framework include (1) Safety: exposure to near-crash situations, crash
prevention, and crash severity reduction; (2) Vehicle mobility: vehicle throughput, both in car following situations and at intersections; (3) Energy /
environment: fuel consumption and tailpipe emissions; (4) Accessibility: personal mobility, for motorists and nonmotorists; (5) Transportation
system usage: response of travelers to changes in mobility and accessibility, as well as potential new modes of transportation such as increased car
sharing; (6) Land use: effects of automation on land use, and (7) Economic analysis: the macro-economic impacts of all of the above changes.
