Model 2070-1A+ 2070E CPU with ATC Engine
Adaptive Traffic Signal Control with Fully Integrated UTOPIA Operation
Overview
The ATC+ firmware is designed to run on the ATC core engine board which is available for a variety of 2070 models, including the Model 2070C and Model 2070E configurations. Full support for UTOPIA is available on all platforms using The native SPOT protocol which allows UTOPIA to manage and supervisor the operation of the traffic signal using the Dual Ring Eight phase operational metaphor with green adaptive control.
