i-35 Traveler Information during construction
The problem:
With more than 35 million travelers annually and 200 directional miles under reconstruction, Central Texas’s I-35 corridor required safer, smarter ways to manage work zones and keep drivers informed.
Our approach:
TTI developed an integrated, automated system that consolidated closure schedules from multiple contractors, predicted traffic delays and delivered real-time updates via social media, texts and digital signs. Technologies included end-of-queue warnings, travel time signs, construction cameras and a dedicated traveler information platform.
The Outcome:
The system reduced nighttime crashes by 60% where EOQ systems were deployed, improved lane closure coordination and enhanced public awareness. Its success influenced statewide standards and drew international attention.
