Built on a unified "Cloud-Edge-Device" architecture, the Duolun platform integrates multi-dimensional traffic data from internet-based navigation services, signal control systems, electronic enforcement devices, and parking facilities. This comprehensive data foundation supports real-time computation and analysis of urban road network conditions and traffic dynamics.

The platform centrally manages various types of dynamic message signs, delivering connected, real-time traffic services to road users. These services include live traffic status updates, incident notifications, violation warnings, parking guidance, green wave speed advisories, intersection signal mode alerts, and left-turn bay assistance information.
