The federal government hands states about $40 billion a year for transportation, money they can basically spend however they want. The result in many places is a lot of expensive, traffic-inducing highways that get clogged with cars soon after they're finished. Can measuring the effect of all this spending lead to better decisions?

US DOT is developing a metric to assess how well states address congestion. This is a minefield— Reformers have been pushing the agency to revise the rule so it takes a broader, multi-modal view of congestion. Stephen Lee Davis at Transportation for America reports 19 senators and 48 US representatives have written a letter to US DOT [PDF] demanding a healthier approach.
The Congress members write: The excessive congestion performance measure should be amended to assess people hours of delay and not just vehicles. This change is critical to account for the many non-single occupancy vehicle users, including transit bus riders and bicyclists and pedestrians traveling along the corridor, which provide critical congestion relief and could be undercounted or even penalized under this measure. US DOT is currently accepting comments about the rule change. You can weigh in and help promote a better policy.

If we focus, as this proposed rule does, on keeping traffic moving at high speeds at all times of day on all types of roads and streets, then the result is easy to predict: states and MPOs will prioritize investments to increase average speeds for cars, at the expense of goals to provide safe, reliable, environmentally sensitive, multi-modal transportation options for all users of the transportation system, despite those goals being stated in federal statute. This singular focus on moving vehicles undermines the progress this Administration has made on multi-modal planning and investments through the TIGER program. Encouraging faster speeds on roadways undermines the safety of roads for all users, as well as the economic vitality of our communities.
The letter also insists that U.S. DOT require state and regional transportation agencies to assess the impact of projects on greenhouse gas emissions.

The District of Columbia spans over 68 square miles. About half its land area goes to buildings, 20% is open space, and over a quarter is "road infrastructure." Among residential land, half is single family detached houses while high-rise apartments occupy less than 2% of DC's total.
I created the above chart using data in DC's Comprehensive Plan. That plan divides land into more categories, but for simplicity, I grouped many of them.
It's important to note that "roads" includes a lot of land that's not paved roads. That's because in many neighborhoods, the official public right-of-way includes much or all of people's front yards; the actual property line is at the building or between it and the sidewalk. This "roadway" space covers yards, sidewalks, tree boxes, some grassy areas, and more. Still, it's a big percentage.
The "jobs" category combines any sort of land use relating to where people work (commercial, industrial, public facilities, federal facilities, and institutional land). The "housing" category groups together of all of the housing categories.
The chart below breaks down the housing category:
Out of the almost 30% of DC's land which was used for housing in 2006, nearly half of that was occupied by single family detached homes— This data is from 2006. I would expect some things have changed in ten years, but not everything. The large amount of "permanent open space"— How do these land use patterns affect our growing city? What changes should we expect, or should we advocate for?

How does a street change in 70 years? In some ways a lot, and in others, not at all, as this video of Los Angeles from the New Yorker shows.
Beyond the increased build-out along the streets, in some places the older streets seem more welcoming to people walking; in others today's streets seem friendlier. While this video is of LA, one can imagine a similar then-and-now for DC.
Would you be willing to create something like this, but for DC? For example, you could grab a Go-Pro and follow the route of the 82 streetcar today.

What does outlawing street hockey in Canada say about public space? Germany is building super highways for bikes, and Oakland is getting its first Department of Transportation. Check out what's happening around the country (and beyond) in transportation, land use, and other related areas!
Game Off!!: Fewer people are playing street hockey in Canada. People playing have received tickets for doing so on neighborhood streets, and some kids say a lot of the hockey they play these days has so much supervision and structure that it's boring. Hockey is one thing, but the bigger issue is that kids feel less welcome in public spaces, like streets, than they used to. (Guardian Cities)
Bike super highways: Germany is building a series of bicycle super highways that will soon connect ten cities and is predicted to take 50,000 drivers off the road. The paths are 13 feet wide and fully separated from car traffic, even at intersections. There's a hope that this kind of infrastructure will usher in alternatives to crowded road and transit systems. (Guardian Cities)
New department in town: Oakland, California doesn't have a Department of Transportation, but it's starting one up this month. The interim director says the new agency will lead the way in answering questions about how to design transportation equitably and inclusively and how to design bike infrastructure without putting drivers on the defensive. (Next City)
Urban growth measures: We often compare cities by their population growth over time. Houston has overtaken Chicago as the third largest city in the US, but that's because counts include suburban growth and annexation, not just central city infill. Analysis by Yonah Freemark shows how central cities have changed since 1960, and that we should consider differences in how cities have grown when we talk about transportation policy. (Transport Politic)
A dense definition: The word "density" makes different people think of different things, and it's pretty unclear what it means relative to cities Are we talking about the density of buildings? People? Another quantifiable statistic? Perhaps the best kind of density is when the result is places where people want to go out and be around one another. (City Metric)

"These are public streets, and navigation apps take advantage of them. Waze didn't invent cut-through traffic, it just propagates it."
Aarian Marshall in Wired Magazine discussing the neighborhood animosity towards the Waze App.
The US highway system is around partly because of a road trip Dwight Eisenhower took right after WWI, and if our leaders don't invest in our transit infrastructure, we'll have to sit back and hope for the best until they change their minds. Check out what's happening around the world in transportation, land use, and other related areas!
Interstate prelude: On July 7, 1919, Dwight Eisenhower struck out on a road trip across the country. His military convoy, the first to cross the US by car, was partly a WWI celebration and partly an effort to gather info on the state of American roads at the time. It averaged 52 miles per day. This road trip and a view of the German autobahns would plant the seeds of the future US Interstate Highway System (History)
Alphabet soup: Sidewalk Labs, a subsidiary of Alphabet (which is basically Google), has offered a suite of tools to Columbus Ohio, the winner of a contest for city design. It includes a program called "Flow," which would help the city modernize its parking system and coordinate ride sharing for low income residents. Though some worry the program will take away from standard transit services. (Guardian Cities)
Surviving the storm: Transit in the United States is often set back by ideological rigidity and under-investment. Laws that keep tax money from going toward infrastructure, for example, make it impossible to get the support needed to repair and expand transit, and they'll stay in place unless leaders change them. The real question is whether transit can survive until those changes happen. (The Hill)
Try something new!: The developers behind a Harris Teeter in Carrboro, North Carolina, want to build something familiar: a grocery store in a tired strip mall. The design has remained very suburban and auto-oriented despite the city's multiple efforts to make it more urban and increase its potential tax base. It's an example of what happens when bean counters at the home office believe what they've always done (strip malls) is the only way to make money. (City Beautiful 21)
No Mickey Mouse ride: Disney has been pushing for a streetcar line from a commuter rail station in Anaheim to the theme park, and local officials were going along with the plan until now. The streetcar has been cancelled by the Orange Country Transit Authority board, with opponents citing low demand for the existing commuter rail and a high speed rail station that's coming in the future as reasons. (Voice of the OC)
Geek city:This week bay area tech incubator Y Combinator has put out a request for applications for its city research endeavor. The agency hopes that in the future, it might be able to find out the best way to build a city from scratch in a way that's better than what exists now. Good luck with that.(Treehugger)

If a driver hits you while you're walking or biking in DC, the law makes it almost impossible to collect from the driver's insurance. A bill to fix that is suddenly in jeopardy just hours before a scheduled vote. Please ask the DC Council to move it forward.
So the months long effort to reform D.C.'s contrib negligence law could unravel hours before the vote. #bikedc—

As of now, DC's "contributory negligence" law says that if a person on foot or bike who is involved in a crash is even one percent at fault for what happened, they can't collect any damages. The Motor Vehicle Collision Recovery Amendment Act of 2015, which is scheduled for a vote today, would let people collect damages as long as they were less than 50% at fault.
Today, Councilmember Kenyan McDuffie plans to introduce an amendment that would change exactly how much a person could collect, using a "comparative negligence" standard that basically means that a person's claim to damages would be proportional to their fault in the crash. It looks as though Councilmember Mary Cheh would oppose the bill if it includes McDuffie's amendment.
Martin Di Caro (@MartinDiCaro) June 27, 2016
Efforts to end contributory negligence, which really does have harmful effects, have been going on for years. There are credible arguments for both McDuffie's and Cheh's positions on how to word the new law, but we need to pass one or the other.
With or without the amendment, the proposed bill will improve the rights of pedestrians, cyclists and other non-motorized road users on DC's streets. That is very much needed, especially as the number of people who use our streets for something other than driving continues to swell.
Update: Councilmember McDuffie moved for the Council to vote on the bill on July 12, and his motion passed.
This morning, 75 people sent 450 letters to Councilmembers urging them to do away with contributory negligence, one way or another. Thank you for your efforts, and look for more from Greater Greater Washington on how pass the bill as the vote nears.
If you want to enjoy a good job and an affordable place to live, you might want to head to Oklahoma, Nebraska, or Iowa. San Jose is apparently the weirdest city in the US, and the people who usually build the freeways in Texas are supporting the idea of tearing one down in Dallas. Check out what's happening around the country in transportation, land use, and other related areas!
Not many housing options: Even when people are willing to make tradeoffs to live in places where housing prices are sky high, it's hard to find quality of life, a good jobs, housing that's affordable all in one place. So hard, in fact, that only three cities in the United States have all 3: Oklahoma City, Omaha, and Des Moines. That's according to a study from the Oregon Office of Economic Analysis. (Gizmodo)
Weird city science: Cities are full of people and activities that many would label "weird." But which one is actually most different from the county's norm? Based on factors ranging from how many foreign-born workers there are to how many people don't own a car, cotton economist Lyman Stone says it's San Jose, and that Oklahoma City is the least weird. (Washington Post)
Tear down this freeway: Texas' department of transportation, unsurprisingly, loves to build freeways. But in a recent report on what to do with an obsolete downtown Dallas freeway spur, the agency opened up the possibility of thinking less like a typical highway department and more like urban designers, with an option to tear down the freeway and let the city reclaim the land. (Dallas Morning News)
The end of big infrastructure: While there are a few possibilities for national-scale projects we'd benefit from, this author argues that the era of building big infrastructure is over. There just isn't much we could invest in that could bring the return of our railroad or interstate system, meaning smaller, local projects and maintenance should be our priorities. (Transportist)
Ride hailing real talk: Right now, ride hailing companies like Uber and Lyft are giving cities a binary set of options: do what we want, or we'll leave. That isn't productive, and the conversation needs to change if there is to be a solution that serves both city residents and companies that want to innovate. Luckily, there are examples of good partnerships. (Sidewalk Labs)
Seattle's big slice: In the Puget Sound region, where Seattle is, there are five "taxing areas" within three counties. The Sound Transit projects that each receives are reflective of how much each pays in taxes, and the organization's leader (a former FTA administrator) says it'd be best to have everyone pay for a new tunnel in downtown Seattle because the entire network will benefit from it.

Quote of the Week
"It's possible San Francisco may have unwittingly demonstrated what I'm calling the Indiana Jones Theory of Housing Regulation. The idea is that when cities increase the burden on new development, whether through inclusionary zoning, expiring tax breaks, or new building codes, they create a deadline boom, as builders rush to get approval before the new laws can take effect. Like Indiana Jones, builders try to get through before the door closes." - Slate's Henry Grabar, explaining his Indiana Jones theory of housing regulation.
Did you know there's a rhyme and reason to how Arlington County's streets are named? Here's an explanation of Arlington's street-naming system.
While Arlington was originally part of the District of Columbia (until 1846), it was not incorporated in the plan of Pierre L'Enfant. Unlike its larger neighbor, Arlington's streets don't follow a strict grid, but development has still followed a somewhat rectilinear pattern. The street-naming system dates back to 1932, and was undertaken in order to convince the Postal Service to allow "Arlington" as the mailing address for the entire county.
The county is divided into northern and southern sections by Arlington Boulevard, a major east-west thoroughfare which bisects the county.
In contrast to Washington, east-west streets are numbered. Since Arlington does not have quadrants, but instead has halves, most streets are identified with "north" or "south" relative to Arlington Boulevard. The directional suffix follows numbered streets, but precedes named streets. Numbered streets increase with distance from Arlington Boulevard in both directions. Accordingly, it is flanked on the north by First Street North and on the opposite side by First Street South. Numbered streets are usually "streets," but when additional streets fill in blocks, "Road" and then "Place" is used.
Named streets run north-south. Like DC, the first letter of the street name and number of syllables indicates where in the grid a street is located. The origin for the named streets is the Potomac River. The first "alphabet" is made up of one-syllable words, the second of two-syllable words, the third of three-syllable words, and the fourth is just one street: North Arizona Street. As distance from the Potomac increases, letters increase successively.
Instead of using "Place" to indicate a second street of the same letter filling in the street grid as DC does, Arlington just uses another word of the same first letter and syllables. In that regard, Danville Street could be followed by Daniel Street. A look at a progression of successive letters shows the strata of the alphabets in Arlington's street grid.
None of Washington's state-named avenues continue into Virginia, so Arlington uses a different methodology for indicating major streets. Like the street bisecting the county, major east-west roads are typically called "boulevards". Examples include Wilson and Clarendon Boulevards.
Major north-south streets are often called "drives." Examples include Walter Reed and George Mason Drives.
Many roads pre-date the addressing system of 1932, and have kept their historical names. These include "roads," highways," Spout Run Parkway, and Columbia Pike.

People want more ways to get around by foot and on bike in the corridor that runs from from Columbia Heights to Brookland, and they want them to be safer. After receiving that message, DDOT drafted potential plans for making it happen.
DDOT's Crosstown Multimodal Transportation Study focuses on an area defined by Kenyon and Harvard Streets between 16th and Park Place; Irving Street and Michigan Avenue around the Washington Hospital Center; and Michigan Avenue from the hospital center to South Dakota Avenue. Cars in the area zip along Irving and Michigan, but for people on bikes and foot, there isn't a safe or easy way to get around (a fact compounded by the congestion once drivers get to either side of the hospital).
Also, the area's transit isn't great. Both the H2 and H4 bus routes connect the Columbia Heights Metro Station, the Washington Hospital Center, and the Brookland Metro Station along the Irving/Columbia Road-Michigan Avenue corridor. However, Medstar also provides shuttle service on the same route between the hospitals and the Columbia Heights Metro every 10 minutes during rush hour and 30 minutes during other times. This service largely duplicates WMATA's service and adds additional traffic to already congested streets.
After the first public workshop about the study, nearly 700 people commented on how to address all of these issues. Back in April, DDOT unveiled three concept plans for the corridor. Here's a summary:
A new street grid
Each of DDOT's proposals suggests removing the Michigan Avenue overpass and creating a street grid west of the hospitals. Doing so would go a long way in making the area safer for people on foot and bike, as it'd get rid of unnecessary high-speed ramps and car lanes; it'd also mean chances to add new green space. How many surface streets are in that grid depends largely on where bus and bike lanes need to be.
More options for bike riders
Those who gave DDOT input were clear that they'd like to see more bike connections, and that those connections be made made up of space that's only for bikes. The proposals include a few options for doing that, from protected bikeways that run in both directions to off-street lanes next to pedestrian walkways.
Around the hospitals and toward Columbia Heights, the stronger proposals would create bike lanes in one of the existing travel or parking lanes. With one exception in one proposal, bikes and buses would not share the same lanes, and west of the hospitals, bike lanes and bus lanes would not be on the same streets.
Dedicated bus lanes
The plans aim to improve bus service (shorter trips, specifically) by creating dedicated lanes for buses. While the extent of dedicated lanes varies among the concepts, they all suggest dedicated lanes on either Irving Street, Columbia Road, and/or Harvard Street west of the hospitals. This would be accomplished by using one lane currently used during rush hour and parking during off peak hours.
No more cloverleaf
None of DDOT's three options would do away with the North Capitol Street overpass. All of them, however, would replace the freeway-style, cloverleaf-shaped ramps that run between North Capitol and Irving with more direct connections. Doing so would make it much easier to keep car speeds down and control traffic flow.
DDOT has scheduled its third Crosstown Study workshop for June 9th at Trinity Washington University. You can give input on the potential plans there.
In addition to the third workshop, DDOT will have two Public Engagement Events on Saturday, June 11: one in Brookland, at the Monroe Street Farmers Market (716 Monroe Street NE), and one on the west side of the Columbia Heights Metro station (3030 14th Street NW).
Little River Turnpike, a major road that runs across Fairfax, is difficult to bike along. The county is looking to change that, though, and a new interactive map lets you make suggestions for how it can.
Stretching from Fairfax City to Alexandria, Little River Turnpike has been a major road since the 1800s and its interchanges with both 495 and 395 mean the road sees a lot of traffic today.
Right now, there are no bike lanes on Little River Turnpike, and sidewalks are hit and miss. Fairfax wants to make it easy to bike between the many neighborhoods and businesses up and down the road.
While there is a master bike plan for Fairfax, some of its roads need a more detailed and focused approach. Little River Turnpike is one of them (the county has deemed it a "policy road"), so planners in Fairfax are conducting the Little River Turnpike Bicycle Study to determine the best way to improve bike riding options there. They're starting with the interactive map above.
One challenge for bike projects along the road is a narrow right of way, which means there isn't much space for bike lanes (and it'd be expensive for the county to buy the space). Also, there some places along the road do have ample space for a stretch, but then it ends abruptly.
The hope with the map is that planners will be able to identify quick fixes in some of the road's trouble spots. The entire study could lead to broader-sweeping changes, but those would be further down the line.
This isn't the only bicycle project coming to Annandale. A number of bike lanes will go in when Ravensworth Road, Guinea Road, John Marr Drive, and Heritage Drive get repaved this summer (all of these roads connect to or run near Little River Turnpike).
Fairfax did this last year as well, when it used an interactive map to crowdsource ideas for bike projects across the county.
