What is load shedding in traffic lights?

Load shedding in traffic lights refers to a strategy used to manage electrical power consumption during peak demand periods or when there is insufficient power supply. In this context, traffic lights may be temporarily turned off or set to flash yellow or red to reduce energy usage while still maintaining some level of traffic control. This approach helps prevent complete power outages and ensures that critical infrastructure remains operational. It is often implemented in response to power shortages or grid failures.
