There’s a new parking app in town that’s supposed to help drivers find spaces more efficiently downtown.

The District Department of Transportation released a tool today to help drivers navigate its demand-based pricing system for street parking in Penn Quarter and Chinatown. In real time, the parkDC app lets drivers know where spaces are available and how much they cost in the two neighborhoods.

Penn Quarter and Chinatown are part of a pilot program in which the cost of street parking fluctuates. The standard metered parking price in D.C. is $2.30 an hour, but since October, some spaces in these two neighborhoods have decreased to as low as $2 an hour, or increased to a maximum of $2.75 an hour.

There are now about 1,000 parking spaces part of the program, around places like the Verizon Center, National Portrait Gallery, National Building Museum, and other frequently-visited spots.

In the app, curbside parking is shown using green, orange, and red lines, which indicate a low, medium, or high numbers of available spaces. Each block’s pricing is listed, as well. The app also gives the location and daily rates of nearby parking garages. Parking information will be available online, too.

While making these resources available, DDOT notes that D.C. law bans drivers from using phones while operating a vehicle, unless it’s a hands-free setup. Violators will pay $100 if caught.

The department expects the new information to help reduce the time that drivers spend looking for parking, improve turnover of high-demand spaces, and reduce congestion.

Once drivers find a space, they still have to use the ParkMobile app to pay, or they can pay at new meters that no longer require people to print receipts and place on them on their dashboards.
