Econolite’s new EOS traffic control software ready for future CAV and smart city systems


One of the leading providers of traffic management systems and equipment, Econolite, has introduced its new EOS traffic controller software, which has been developed to prepare agencies for connected and autonomous vehicles and smart city systems.

Econolite’s new EOS is a next-generation, easy-to-use, web-based user interface traffic control software that is built on a completely new and more robust dynamic core framework. EOS is designed to expand traffic control capabilities, preparing agencies for the upcoming demands of connected and autonomous vehicle (CAV) and smart city traffic control systems. The new software platform has been developed for Econolite’s Cobalt ATC, Safetran 2070C, and other properly configured ATC controllers.

EOS was founded upon the rich set of NTCIP 1202 and Econolite proprietary traffic control features, and provides an expansion of traffic control capabilities, while focusing upon simplicity and ease-of-use. EOS features a brand-new coordinator design, enabling immediate coordination decisions rather than awaiting a cycle endpoint. This coordinator includes adaptive split balancing using the Purdue GOR/ROR5 metric for phase failure.

EOS’s dynamic Core and Coordinator enable a new Signal Control and Prioritization capability. EOS supports an internal priority request server (PRS), allowing receipt and prioritization of multiple concurrent and even contradictory priority requests, while mitigating the impact on traffic.

EOS is designed with traffic control phase timing and sequencing modules that support real-time changes to signal phase sequencing and timing, as well as the latest J2735 dedicated short range communications (DSRC) messages such as SPaT/MAP, supporting CAV applications. EOS helps provide the necessary software bridge that enables vehicle-to-infrastructure (V2I) communications; a critical component of the CAV equation.

Econolite is currently involved in some of the industry’s most prominent CAV initiatives, including: University of Michigan Transportation Research Institute (UMTRI), MTC Leadership Circle, and the Mcity CAV test facility; MMITSS with the University of Arizona and PATH; the V2I Reference Implementation project; and numerous CV projects. In addition to its strategic partnership with Savari, Econolite is also involved in cooperative efforts with leading CV technology providers, such as Battelle, Texas A&M Transportation Institute (TTI), and others.

“EOS represents new levels of operational efficiency and capability for traffic controller software,” said Econolite’s vice president of engineering, Eric Raamot. “EOS provides improved real-time decision making by enabling dynamic ‘on-the-fly’ changes to phase timing, sequencing, and coordinated split control, serving the immediate needs of connected and autonomous vehicle applications.”
