Stanley , Paul Sorensen , Constantine Samaras , Tobi A. Oluwatola Key Findings Automated Vehicle Technology Offers Several Benefits Without driver error, fewer vehicle crashes will result. The mobility of the young, the elderly, and the disabled will be increased. Traffic flow could be more efficient and congestion decreased. Vehicle occupants could spend travel time engaged in other activities, so the costs of travel time and congestion are reduced. Fuel efficiency can be increased and alternative energy sources facilitated. Because such vehicles won't need proximate urban parking, space used for parking could be repurposed. There Are Possible Drawbacks Because the technology would decrease the cost of driving, congestion might increase, rather than decrease. O...
