How much does the moveDC plan relieve congestion? Not much, actually. The map on the left assumes moveDC is implemented; the map on the right is the baseline. Image: DDOT
Yesterday, we ran the first part of my conversation with some of the architects of moveDC, the new long-range plan from the District Department of Transportation. MoveDC calls for the implementation of congestion pricing, 69 miles of high-capacity transit in addition to the 22 miles of streetcar already planned, a new downtown Metro loop, 72 miles of protected bike lanes, 136 miles of painted bike lanes, and 135 miles of off-street trails over the next 25 years.
In yesterday’s installment, I talked to Matt Brown, DDOT’s new acting director; Colleen Hawkinson, strategic planning branch manager at DDOT’s Policy, Planning and Sustainability Administration (PPSA); and Sam Zimbabwe, associate director of the PPSA, about the prospects for the most dramatic changes envisioned in the plan, the pitfalls of a focus on Complete Streets, and the reality that cars will not win every tradeoff anymore.
Here we pick up where we left off.
In the plan, there are two side-by-side maps (above) of future road congestion: with the changes laid out in the plan and without. And they’re very similar. Not identical, but very similar.
SZ: They’re not identical. But you have to remember, this removes a lot of vehicular capacity in exchange for some other things. So in order to create the space to provide more options, there was a need to manage the person-carrying capacity of the roadway system. And there were two principles that went along with that.
One is that there’s always a way to not pay the charge. The way we modeled it, it’s roughly equivalent to a round trip metro fare.
I thought that was interesting, to basically say you’re not going to pay any more to drive than to take the metro.
SZ: And carpools might be free. But everybody’s paying. District residents have to pay. And as we look at the whole system, we’re accommodating the same number of car trips in a day in 2040 as we are today, even as the District grows by 170,000 residents and a couple hundred thousand jobs.
CH: And we could have made these colors [on the map] pretty much whatever we wanted to. If we add more roads that would be tolled, like Massachusetts Avenue and Connecticut Avenue, we could get different colors in here. But it didn’t seem like we needed that to keep the network moving. This seemed to be a sweet spot in terms of the size of the cordon charge.
SZ: In the region, we’re starting to get experience with tolls. People ride the ICC [which is tolled and free-flowing]; they take 495 [which is free and congested]. They start to see what that means.
