The system used to change traffic lights for emergency vehicles is ITCS (Intelligent Traffic Control System). Here's a step-by-step explanation:

1. The Intelligent Traffic Control System (ITCS) is a technology that allows the traffic lights to be controlled remotely or automatically.

2. Emergency vehicles like ambulances, fire trucks, and police cars are often equipped with a special transmitter that sends a signal to the ITCS.

3. When the ITCS receives this signal, it changes the traffic lights along the route of the emergency vehicle to green, allowing the vehicle to pass through intersections without delay.

4. This system helps emergency vehicles to reach their destination faster and more safely, reducing the risk of accidents.

So, among the options provided, ITCS is the correct answer.
