closely related. In the United States, the National Highway Traffic Safety Adminis- tration (NHTSA) released in 2013 a formal classification system. NHTSA abandoned this system when it adopted the SAE stan- dard last September. As we begin the New Year, our school bus supplier industry is most likely planning to solicit ideas for the next generation of school buses. By collectively gathering their cus- tomers and dealers as advisory groups, ideas will be debated that begin with the custom- ers input as well as the dealers, these ideas
SAE automated vehicle classifications:
Level 0: Automated system has no vehi- cle control, but may issue warnings. Level 1: Driver must be ready to take control at any time. Automated system may include features such as Adaptive Cruise Control (ACC), Parking Assis- tance with automated steering, and Lane Keeping Assistance (LKA) Type II in any combination. Level 2: The driver is obliged to detect objects and events and respond if the automated system fails to respond properly. The automated system executes accelerating, braking, and steering. The automated system can deactivate immediately upon takeover by the driver. Level 3: Within known, limited environ- ments (such as freeways), the driver can safely turn their attention away from driving tasks. Level 4: The automated system can control the vehicle in all but a few environments such as severe weather. The driver must enable the automated system only when it is safe to do so. When enabled, driver attention is not required. Level 5: Other than setting the destina- tion and starting the system, no human intervention is required. The automatic system can drive to any location where it is legal to drive
then end at the equipment manufacturers engineering department. It is they who ultimately study the viability of an idea. Just think if we could help driver be-
havior through the Level 2 automation of control over severe rear end collisions, roll overs, and danger zone incidents, just to name a few! ●
