   An autonomous vehicle manufacturer is developing a Level 3 system where the driver can take over when requested. The system must decide when to alert the driver to take over and when to perform an emergency maneuver itself. The vehicle has limited sensor range in heavy rain. Which approach best ensures safety?

   • AAlways alert the driver to take over whenever any sensor reading is uncertain
   • BUse AI to continuously assess sensor confidence and driver attentiveness, and initiate a takeover request or emergency braking based on the level of uncertainty
   • CDisable autonomous features in rainy conditions and require the driver to take full control
   • DAlways perform emergency braking whenever the system detects any obstacle, regardless of driver state

   A city is deploying an AI traffic management system. They want to reduce emissions and improve emergency vehicle response times. Which approach is most effective?

   • AA multi-objective reinforcement-learning controller that optimizes signal timing to reduce stop-and-go traffic and provides preemption for emergency vehicles.
   • BA system that uses cameras to detect emergency vehicles and manually adjusts signals from a control center.
   • CA system that optimizes signals solely for average vehicle speed, assuming lower emissions.
   • DA system that gives emergency vehicles a green light at every intersection, regardless of traffic conditions.

   A city is deploying an AI traffic management system. The system must handle both regular traffic and emergency vehicles. It must also provide data to the public transit authority for scheduling. Which design is most effective?

   • AA centralized AI platform that integrates real-time traffic data, emergency vehicle preemption, and shares data with transit scheduling systems
   • BSeparate AI systems for traffic signals, emergency vehicles, and transit, with no data sharing
   • CA system that prioritizes emergency vehicles at all times, even if it disrupts regular traffic
   • DA system that only uses historical data to set fixed signal timings

   Which of the following best describes how AI can improve routing for individual drivers to reduce congestion?

   • ABy providing static maps that show the shortest distance route
   • BBy suggesting routes based on historical traffic patterns only
   • CBy analyzing current traffic data to recommend routes that balance travel time across the network
   • DBy limiting the number of vehicles allowed on highways during peak hours
