Northern Virginia officials have the latest way to carpool — and they’re going to pay military workers and contractors to do it, at least for a while. A new pilot ride sharing program managed by the Northern Virginia Regional Commission will give drivers to Fort Belvoir, the Mark Center or Marine Corps Base Quantico $25 in gas per month along with a reward based on mileage if they’ll give a few other commuters a lift.

But this isn’t just your grandma’s carpool. The new program, called real-time ridesharing, will allow commuters to find rides from wherever and whenever they need using a smart phone app.
