1) The document discusses connected and automated vehicles and their implications for transportation. It summarizes two types of automated vehicle technology: self-driving vehicles that make autonomous decisions and connected vehicles that can communicate wirelessly. 2) It describes how connected and automated vehicles could improve traffic safety and efficiency by avoiding collisions, optimizing traffic flow, and enhancing capacity. However, these technologies may also influence traveler behavior, land use patterns, and mode choice in ways that are still uncertain. 3) The impacts of automated vehicles will depend on whether they are used as privately owned vehicles or shared through a mobility system. Privately owned automated vehicles could increase vehicle miles traveled and congestion, while shared automated vehicles have the potential for greater
