Constrained budgets are spurring innovations that efficiently use existing intersection footprints. From a previously sponsored research effort by the Office of Operations Research and Development (R&D), DRLT and CLT treatments were identified as two cost-effective and innovative treatments to mitigate congestion attributed to heavy left-turn (LT) volumes at diamond interchanges and signalized intersections
