WASHINGTON (WUSA9) — The newest Metro shutdown is testing patience, but it’s also testing researchers. They can't get figure out if the rail cutoff is causing traffic on the roads.
JJ Biel Gobel with the Center for Advanced Transportation Technology at the University of Maryland said travel times are about the same, if not better, than this time last year.
That debunks theories that the week-long Blue and Yellow line shutdown between National Airport and Braddock Road would choke highways.
Researcher Mark Frantz said the Center needs more data. He pointed to the July 4th holiday keeping traffic down.
“I think the holiday has had an impact,” he said. “In my opinion, a positive impact.”
"They’ve picked the right time of year," added Gobel.
Metro has been urging riders to work from home. University researchers want a few more days of data to see if that’s the case.
