Abstract:This research is intended to provide a technical analysis of the potential impacts of automated vehicles (AVs) on current light-duty vehicle miles traveled (VMT) and parking decisions, the economic desirability of widespread deployment of partially automated technologies, and methods for existing roadways to transition to connected and automated vehicle (CAV) transportation, so that policymakers can make more informed decisions during the transition to CAVs. This work looks at AVs from a point in time where vehicles are equipped with driver assistance systems (Level 1) to a point in time where AVs are driverless (Level 5) and can self-park. This research examines the likely implications of AVs through a four-part assessment: (Project 1) Potential Economic and Safety Impacts of Driver Assistance Systems presents a benefit cost analysis of partially automated crash avoidance technologies; (Project 2) Transitioning to Connected and Automated Vehicle Transportation uses the Pennsylvania Turnpike as a case study examining the effects of reserved lanes for commercial truck platooning; (Project 3) An Agent-Based Driverless Vehicle Parking Decision Model uses Seattle parking lot information to investigate the potential travel, economic, and energy implications of changes in parking decisions due to vehicle automation; and (Project 4) Potential Travel Demand Impacts from New Demand from New Users looks at potential increases in travel from non-drivers, seniors, and people with travel-restrictive medical conditions.
