  LANSING, Mich. (AP) - As Michigan readies for a vote on raising taxes to smooth a deteriorating network of roads, one reason is because it's contending with the reality that federal money for the projects is down.

About $1 billion from the Federal Highway Trust Fund was made available to Michigan in 2013. That's 8 percent less than five years earlier and 15 percent less when adjusted for inflation, according to figures compiled by the Associated Press.

Transportation officials in Michigan are hearing from their federal counterparts this week about a funding shortage that may affect next year’s orange barrel season.

The problem is fuel efficient cars, at least partially. More fuel efficient cars mean less gas revenue flowing into the Federal Highway Trust Fund.  The federal gas tax rate has remained at the same level for two decades.
