What would fix Pennsylvania and Potomac?
It's confusing and inconvenient to cross the intersection of Pennsylvania and Potomac Avenues on foot, to get to and from the Potomac Avenue Metro station. Could a different intersection design work better?
The District Department of Transportation (DDOT) kicked off an environmental study of the intersection with a public meeting Thursday night. This was the first of 3 meetings they will hold this year. They've also posted their presentation online.
Last week's was a "scoping meeting," the required first meeting of a NEPA process. Next, the team will develop alternatives, present them to the public, review their impacts, have public agencies review the draft document, and present a third time.
Redesign would accommodate crossing straight through
According to the study team, many people end up crossing straight through the intersection, and have worn a "desire line" in the median. They are crossing between signals, however, which may not be very safe. The team plans to design the intersection to help people cross safely in the direction they want to.
A prior study proposed rebuilding the intersection as a square, which would include crosswalks directly through the center from the Metro. However, that concept design hadn't gone through engineering review, and included turns too sharp for buses, Geoff Hatchard reported from the meeting.
The presentation has two concept sketches for the intersection. One would make Potomac Avenue end on each side at a T-intersection with Pennsylvania, and another would build an oval, though smaller and rounder than the one in the 2006 concept.
These sketches don't show crosswalks across Pennsylvania Avenue except in the center, but the planners explained in person that they will indeed include marked crosswalks at every intersection. That's important, especially since by DC law, every place a street meets another is a legal crosswalk, whether or not there are stripes.
Factors to consider in the design
The team stressed that these are not the final options, just early concepts, and they will refine and develop them more throughout the next phase of the process. As they do, here are some concepts they should keep in mind:
Traffic calming: One of the ways to make this intersection safer for pedestrians is to slow down the vehicles. DC recently installed a speed camera Pennsylvania Ave between 12th and 13th, which is a little over one block to the west. However, cars still speed through this stretch of road. The alternatives should include engineering solutions that will calm the traffic.
Seamless transit connections: This intersection has a Metro station and is a major bus transfer hub. Many of the pedestrians in this area are trying to transfer between buses or bus and Metro. The current configuration usually leads pedestrians to dash across Pennsylvania Ave to catch a bus. The proposed alternatives should consider bus stop locations.
Location of the CaBi station: When DDOT designed the original "square" concept, the Capital Bikeshare program didn't exist. The station is currently located on the southwest corner of Pennsylvania and Potomac Ave.
One of the residents at the meeting pointed out that the current location is awkward if a rider wants to go westbound on Pennsylvania Ave. Also, people taking CaBi to or from the Metro have to cross Pennsylvania to reach the station. DDOT should consider where to locate the bikeshare station to make it as easy as possible to access the bikes and to help riders enter the flow of traffic safely.
Cyclist safety: One of the proposed concepts is a traffic oval. The engineers on this project explained that the traffic ovals are a method to calm traffic. While that may be the case from a technical perspective, traffic circles and ovals can be a cyclist's worst nightmare, especially when there aren't any identified bike lanes. In trying to address pedestrian safety, DDOT should not create unsafe conditions for cyclists.
Connect projects on both sides of the river: Another NEPA process is underway for reconfiguring the Minnesota Avenue- Rethink the Kiss-and-Ride: The Potomac Avenue Metro Station has a Kiss- What will happen with green space? The National Park Service controls the current median of Pennsylvania Avenue, and would likely control the larger green space if DDOT chooses an oval-type design, Brian McEntee reported from the meeting. However, NPS does not have the resources to maintain its small parks around DC very well, and regulations often inhibit actively programming the space for the neighborhood.
This was a primary concern of many people at the meeting, McEntee said. Many worried this would create a dead space without any activity. Some suggested a playground; NPS rules have interfered with efforts to build a playground downtown as well.
DDOT will present its alternatives at the second public meeting sometime this spring.

Any information on the traffic volumes from each road? I'd wonder if any of the 14th St or Potomac Ave legs could be removed or cul-de-sac'd, merging any remaining legs into a more conventional single intersection. Would have to consider bus flows & wouldn't make much gain in greenspace, but at least it'd give a central controlled ped crossing & more conventional geometry favorable toward bikes, cars, trucks, and buses.

I hope they make some good improvements here. I've seen a couple of pedestrians get hit by cars here and many near misses. I'm really interested how this will work with the Barney traffic circle project as well.

Crossing to and from the grocery store and condo building (to the SW of the metro station) involves a fairly straightforward walk across Pennsylvania and 14th st. It could potentially involve waiting for three cross signals, but it's usually fairly well synced.
So I'm guessing this is designed to benefit those heading toward 14th st. south, or to Pennsylvania ave heading SE, but to be honest, I'm having a hard time understanding who these changes would benefit.

Also in my dream world someday street cars woudl be back running down the median, and it looks as if the plans woudl prevent that from happening.

I assume they do the same thing in the evening, in reverse, but having to cross six lanes and a median on Penn. Ave. to catch their buses going home. And I don't really know that section so well, but I assume from comments that there isn't a direct path and that those pedestrians are jaywalking there too.

With each of the designs, there are serious issues with riding a bike (bikeshare or otherwise) from the Harris Teeter to points north of PA Ave. Since 13th, 14th, and 15th streets are all one way toward the south as they cross PA Ave, riders traveling to destinations north of PA Ave, have to travel Potomac Ave to Kentucky Ave. Under the current configuration, cyclists can cross PA Ave at a traffic light. Looking at the published bikeshare data, it appears that places on the hill to the north are the destination of a large number of the trips from the Potomac Ave/PA Ave bikeshare station.
The proposed designs will make it significantly more difficult to get to Potomac Ave to travel north. One way to address this would be to reverse 15th St between Potomac Ave and Kentucky Ave to run one way north. PA Ave would also benefit from some traffic calming measures to make it more bike friendly.

Cars will have to be taught to yield to pedestrians and bikers crossing and exit when they want to leave the circle, but that just follows from the one simple rule. The pedestrian is on the circle, and the car wants to leave the circle...

Actually, there's a lot of vehicle traffic coming down Potomac from the east looking to continue across the intersection to the western side of Potomac Avenue to either go to Harris Teeter or go to the SE freeway. I'm not certain about either design either. As a bike commuter who goes along Potomac westward neither looks particularly inviting. However, as a driver, I suppose I'd go with Option 1, if that's the best they can come up with.

The problem is there's too much crap at this intersection: a metro stop, multiple bus stops, a major thoroughfare, a school and a grocery store. Eliminate two.

But it's fantastic if you're heading EB and want to end your trip at the station.
DDOT should consider where to locate the bikeshare station to make it as easy as possible to access the bikes and to help riders enter the flow of traffic safely.
I'm not sure I understand this criticism. The CaBi station will likely be on one side of the street or the other. If you put it on one side, you're going to have to cross traffic to enter the flow of traffic on the other.
The problem here would be in the awkward street crossings, not the station location per se.

There are a number of problems with that light, because it coincides withe walk signal for pedestrians crossing NW Pennsylvania Ave.
First, the green light for those cars is right in front of Metro, which is maybe 30-40 feet before they actually get in to Pennsylvania. So these cars get a green and build up a little speed, only to have to yield to pedestrians crossing Pennsylvania. Most know this, but others don't.
Second, those cars are making a really soft right onto Pennsylvania. That increases the speed that they want to take that right turn with.
Third, it's awkward for pedestrians crossing from the north side of Pennsylvania toward HT/Jenkins Row to make sure a car is going to yield coming onto Pennsylvania because they're walking in the crosswalk with their backs essentially facing oncoming traffic. It can be hard to tell which cars are making a left and continuing onto Potomac (or Pennsylvania SE) and which are planning to go onto NW Pennsylvania. During rush hour at late night, you're essentially walking with your head turned completely around to make sure you don't get taken out.
Also, the Kiss and Ride is awkward and hazardous for pedestrians, and seems annoying for drivers too. 14th St. should not connect to that intersection as it is now.

I agree that the kiss and ride is cumbersome and out of place. The biggest problem is the fed insistance on maintaining 4 vehicular lanes on Penn as an emergency evacuation route, which provides a big open space the rest of the time and contributes as much to speeding as anything else.

Unfortunately there is going to be no perfect answer given the constraints of space and competing interests. That is a major transportation spot - Metro, 4 places to catch buses, Penn. Ave traffic, and north/south traffic, people running to catch this or that - it is a hot mess. On some "corners" it is sometimes hard to figure what exactly is going on and some there just isn't enough space.

In an ideal world, I would love to see a little joint development/air rights apartments built above the Potomac Ave Metro entrance.

I think the issue is that it makes more sense to put it on the same side of PA as the Metro Station, not opposite. Many cyclists are likely coming from or going to the Metro station.
It's true that a better intersection is needed, but also true that the north side of Penn is a better location for a CaBi station. Even better would be a CaBi station on each side.

Though Penn & Potomac may be a not-great intersection, it's a non-terrible intersection. I'd much rather spend money on the terrible intersection(s) (esp for peds & bikes) at and on either side of Minnesota & Penn just across the (Anacostia) river. Especially now since that's no longer the only 395 - 295 connector, there should be some real opportunity to rebalance traffic flow patterns.
