Adaptive traffic management

Definition

Adaptive traffic management refers to a system that uses real-time data and advanced algorithms to optimize traffic flow and improve road network efficiency. This approach adjusts traffic signal timings, reroutes vehicles, and informs drivers of real-time conditions, ultimately enhancing overall network resilience. By adapting to changing traffic patterns and unforeseen events, this strategy helps maintain smoother transportation operations and reduces congestion.
