What do Active Traffic Management Systems do?

  1. Increase fuel efficiency

  2. Reduce congestion

  3. Monitor vehicle speeds

  4. Automate traffic lights

The correct answer is: Reduce congestion

Active Traffic Management Systems (ATMS) are designed to reduce congestion on roadways. This is done through various methods such as collecting data on traffic flow and adjusting signals and lane assignments in real time. Although increasing fuel efficiency and monitoring vehicle speeds may be a byproduct of a well-functioning ATMS, they are not the main purpose. Additionally, ATMS do not automate traffic lights, as they are controlled by trained traffic engineers and are not fully automated systems.
