A city plans to introduce autonomous buses to improve public transportation. The city also wants to use AI to analyse traffic patterns and reduce congestion.
Based on the above scenario:
(a) State one characteristic of the autonomous bus.
(b) Explain how the bus detects obstacles while moving.
(c) Mention one advantage of using AI in managing public transportation.

(a) The autonomous bus can operate on its own without human intervention, as it uses sensors and AI to take decisions according to the situation on the road.
(b) The bus is fitted with a variety of sensors, such as radar, cameras, lidar and proximity sensors, which continuously observe the surroundings. When an object comes into the sensor's field, the sensor sends this input to the controller, which processes it and instructs the actuators to slow down, stop or change lanes to avoid the obstacle.
(c) AI can analyse traffic patterns in real time and optimise signal timings and routes, which helps in reducing traffic congestion.
