The traffic signal controller represents one of the most important intelligent technology and communication components of a signalized intersection. As such, today's advanced traffic signal controller must integrate leading edge electronics, while supporting industry standards and specifications. ICS developed and provided an Advanced Transportation Controller (ATC) to one of its traffic management systems clients. A combination of ATC controller open architecture functionality and the latest handheld technology features a breakthrough touchscreen user interface matched with a Linux-based operating system, making programming and access to functions the easiest in the industry. Together we are providing a more sophisticated safety system for intersections across the globe.
