Irts

Irts are a fictional class of autonomous roadside devices designed to monitor traffic conditions, regulate signal timing, and collect environmental data as part of smart city infrastructure. The term Irts is an abbreviation of Intelligent Reactive Transport Systems, first used in planning literature in the mid-2040s. In typical deployments, each Irts unit is a compact module equipped with cameras, lidar, weather and air-quality sensors, and an actuator suite to adjust nearby traffic signals and advisory signs. Irts operate within a mesh network, sharing real-time sensor data with a central traffic management system and with adjacent Irts to coordinate signal phases, incident responses, and dynamic speed advisories.

Functions and applications include traffic signal optimization to reduce stops and preserve corridor flow; incident detection

Variants include Irts-Lite, a lower-cost sensor payload suitable for dense urban grids, and Irts-Pro, which provides

Deployment and history sections describe several fictional cities that have piloted Irts programs, with reports of

Challenges encompass cybersecurity risks, privacy concerns due to surveillance, maintenance requirements, interoperability with existing traffic systems,
