Offering improved usability with redesigned user interface and traffic control algorithms, Econolite’s EOS is the next-generation traffic controller software developed for the Econolite Cobalt and other properly configured ATC controllers. EOS was founded upon the rich set of NTCIP 1202 and Econolite proprietary traffic control features. EOS provides an expansion of traffic control capabilities, while focusing upon simplicity and ease-of-use. This software provides a timely preparation for the forthcoming demands of Connected Vehicle traffic control systems. EOS is developed for the Econolite Cobalt ATC, Safetran 2070C, and other properly configured ATC controllers.
