What does active traffic management utilize to optimize roadway performance?

Active traffic management (ATM) employs dynamic real-time data and technology to optimize roadway performance. This approach involves continuous monitoring of traffic conditions and the immediate application of management strategies in response to changing traffic situations. Technologies such as traffic cameras, sensors, and variable message signs provide instant information on current traffic flow, congestion levels, and incidents.

By using this real-time data, traffic operators can adjust traffic signals, modify speed limits, or implement lane changes proactively, thereby improving traffic flow, reducing delays, and enhancing overall safety on the roadways. The flexibility and responsiveness of ATM systems are key to addressing the dynamic nature of roadway performance, making it significantly more effective than relying solely on historical data, fixed rules, or seasonal patterns, which may not reflect current conditions.
