   A smart city is integrating AI into its traffic management center. The system receives real-time data from vehicle sensors, traffic cameras, and pedestrian counters. It must simultaneously (1) reduce congestion, (2) ensure safety for pedestrians and cyclists, and (3) allow human operators to override decisions in emergencies. The city has a limited budget and cannot replace all existing infrastructure. Which solution best balances these requirements?

   • AUse AI to predict maintenance needs for all traffic signals and replace them with smart signals
   • BInstall autonomous vehicle-only lanes and require all vehicles to be self-driving within a year
   • CDeploy an AI system that adjusts signal timings based on real-time data and includes a human-in-the-loop override for safety-critical decisions
   • DImplement a driver monitoring system for all vehicles that alerts drivers to hazards

   In an autonomous vehicle, what role does AI play in collision avoidance systems?

   • AIt relies solely on GPS to know the vehicle's position
   • BIt only alerts the driver with a sound warning
   • CIt processes sensor data to detect obstacles and decide on evasive actions
   • DIt provides a constant speed to avoid sudden changes

   What is a key benefit of using AI to optimize public transit scheduling and routing?

   • AIt guarantees that every bus is always full
   • BIt reduces operational costs by eliminating all empty seats
   • CIt matches vehicle supply with passenger demand to reduce wait times and underutilized trips
   • DIt replaces all human drivers with automated vehicles

   A mid-sized city is experiencing worsening congestion on a corridor with five signalized intersections. The traffic department wants to reduce average travel time without installing new sensors. They have historical volume data and live GPS probe data from a ride-hailing partner. Which approach should they implement?

   • AInstall inductive loop detectors at each approach and use a fixed-time plan updated monthly from the historical data.
   • BDeploy a reinforcement-learning signal controller that adapts green times in real time using the GPS probe data as a proxy for demand.
   • CImplement a camera-based system that detects queue lengths and adjusts signals only when a queue exceeds a threshold.
   • DUse a predictive model to forecast congestion and broadcast suggested alternate routes to drivers via dynamic message signs.

   In an intelligent traffic management system, how does AI primarily contribute to reducing congestion at signalized intersections?

   • ABy physically widening roads to increase vehicle throughput
   • BBy analyzing real-time traffic data to adjust signal timing dynamically
   • CBy replacing traffic lights with stop signs at all intersections
   • DBy enforcing a fixed signal cycle that repeats every 60 seconds
