Which type of traffic signal timing adjusts based on current traffic conditions?

The type of traffic signal timing that adjusts based on current traffic conditions is adaptive timing. This system uses real-time data to modify the signal phases and durations, allowing for a more responsive approach to traffic flow. By analyzing current traffic patterns, pedestrian activity, or even emergency vehicle approaches, adaptive timing can optimize signal phases to reduce congestion and improve safety.

This type of system contrasts with fixed timing, which operates on pre-determined schedules regardless of actual traffic conditions. While fixed-time operation follows set cycles, and dynamic timing may offer some level of adjustment, adaptive timing stands out because it is specifically designed to react continuously to changes in traffic flow, making it the most effective choice for managing varying traffic conditions efficiently.
