• Description:
  Freeway merge and diverge areas are typically associated with unsteadiness and congestion due to an increase in lane changing and slowing down to accommodate vehicles that want to enter or exit the freeway. While waiting on anticipated benefits of connected and automated vehicles (CAVs), cities continue to struggle with worsening freeway congestion. Beyond widening roadways, few short-term, low-cost options exist for increasing freeway capacities. At the Federal Highway Administration’s Saxton Transportation Operations Laboratory (STOL) at the Turner-Fairbank Highway Research Center in McLean, VA, a team of researchers are testing various solutions to these capacity problems.
