Adaptive traffic signal control

Definition

Adaptive traffic signal control refers to a system that adjusts the timing of traffic signals in real-time based on current traffic conditions. This technology uses data from various sensors and cameras to analyze vehicle flow and optimize signal timings, ultimately improving traffic efficiency and reducing congestion. By dynamically responding to fluctuations in traffic patterns, these systems contribute to more eco-efficient transportation solutions.
