President Barack Obama is envisioning a time when cars will be able to talk with other cars or with America�s roads. He says such technology could prevent crashes, cut down on traffic and save gasoline.

Obama on Tuesday will visit a federal highway research center in northern Virginia. The White House says he will highlight partnerships between the Transportation Department, auto-makers and the University of Michigan. The groups are developing and testing vehicle-to-vehicle and vehicle-to-infrastructure communications technology.

The trip is part of Obama�s push for Congress to shore up funding for highways and transportation. He says that�s key to keeping the U.S. competitive.

Obama wants a long-term commitment to keep money flowing to states. His administration has warned that the Highway Trust Fund will need help by early August.
