End-of-queue warning systems alert drivers about slowing or stopped vehicles ahead
What’s the Problem?
For decades, transportation agencies across the country have sought ways to reduce rear-end crashes in and around construction zones. TTI researchers are supporting the Texas Department of Transportation’s (TxDOT’s) $2.1 billion I-35 Expansion Project with a first-of-its-kind traveler information system. The construction project covers 96 miles of I-35 across four Central Texas counties and often requires implementing active work zones during heavy travel times.
