COLLEGE PARK, Md. (WUSA9) -- Scientists at the University of Maryland are working to make that huge Metro slowdown a little bit less of a pain.

They're plugging millions of bits of data into a massive computer simulation.

All in hopes of predicting where and when back-ups and bottlenecks will choke traffic, as thousands more people hit the road to avoid long waits for trains.

Metro's big maintenance surge starts Saturday and many of us are still making plans to deal with it.

For now, the National Transportation Center data at the University of Maryland is mainly targeted at Metro and local transportation departments.

but by this time next year, the experts hope to have a mobile app that will not only tell you how bad the traffic is, but how bad it's going to be when you get to where you're going.
