More than 20% of people bicycle to work in some DC neighborhoods

Over 20% of commuters in Bloomingdale, Mount Pleasant, and Petworth get to work each day primarily using a bicycle. That doesn’t even include people who use bikes to reach Metro.

This fascinating map is part of the background data DDOT is preparing to study a possible protected bikeway on or around 6th Street NW.

It shows how hugely popular bicycling can be as a mode of transportation, even in the United States. What’s more, this data actually undercounts bicycle commuters by quite a lot.

It’s originally from the US Census’ American Community Survey, which only counts the mode someone uses for the longest segment of their commute. People who bicycle a short distance to reach a Metro station, then ride Metro for the rest of their commute, count as transit riders rather than bicyclists.

Watch the world’s urban population explode on one map

The number of urban areas in the world with a population over one million has exploded since 1950. This map shows just how extreme that explosion has been.


Image from KPMG.

On the map, you can see how in 1950 the world’s scant million-plus cities were heavily concentrated in western Europe, the northeastern United States, and Japan. Since then, not many new ones have popped up in those places, but the rest of the world has caught up big time.

By the 1980s, China, India, and southeast Asia are challenging the west’s dominance. By the turn of the millenium, the middle east and central Africa join the party. South America keeps up a slower but steady pace the whole time.

What jumps out to you?

See every Metro train and bus on one live map

This map shows the real-time location for every WMATA bus and train in the Washington region. It’s a cool way to see how much transit is out there, and where it’s running right this second.

The map is called TRAVIC and was produced by the University of Freiburg. The Washington map was made using using open data from WMATA.

Although the Washington map shows only WMATA transit, the same website includes maps for dozens of cities all over the world. You can compare what transit is like in diverse places, from Albuquerque to Paris.

I’ll be staring at this a long time.

MD & VA commuter rail look great together on one map

Maryland’s MARC train and Virginia’s VRE are very similar regional rail systems. This map shows what they might look like as a single integrated regional network.


Map from Peter Dovak at Transit Oriented.

Although MARC and VRE are so similar, they operate totally independently of each other. Riders on one may not even be aware the other exists. This map would help solve that.

The two agencies will probably never merge, but it might someday be possible to integrate their operations to work more like a single system. MARC trains might run across the Potomac into Virginia, and VRE trains might one day continue north into Maryland. It would be difficult but possible.

In the meantime, this map from Peter Dovak at Transit Oriented is a nice unofficial first step. And it’s easier on the eyes than the current official MARC or VRE maps.

Check out DC’s charming but incomprehensible 1975 bus map

Washingtonians hoping to catch a bus in 1975 consulted this friendly-looking hand-drawn map. Charming as it may be, the map has no lines. Rather, designers wrote the name of each bus route over and over along its path through the city.


Image from DDOT.

Transit riders and cartography experts can’t fault the map designers too much. It was more challenging to illustrate detailed networks before the days of computers, and even in recent years some WMATA maps have been just as hard to follow.

Legibility aside, the map actually includes some very progressive elements considering its vintage. According to the legend, it only shows “all-day routes with frequent service,” an incredibly useful idea that’s picked up a lot of steam in the past five years.

Other progressive elements shown on the map include bike paths, although the Mount Vernon and Rock Creek trails appear to be the only ones, and much of its text is translated into Spanish.

The map also includes a fun vignette of the Metrorail system, which had yet to open but was less than a year away.


Image from DDOT.

On the other hand, some things never change. The legend for the Metrorail vignette notes Metro’s first phase was scheduled to open later in 1975. In actuality it didn’t open until 1976.

Finally, there are several other vignettes on the reverse side:

All the buildings and races of DC, Arlington & Alexandria on one map

This incredibly cool map shows the footprints of every building in DC, Arlington and Alexandria, colored according to the predominant race living on that block.


Map from Kenton Ngo at kentonngo.com.

By coloring blocks only according to the most populous race on each block, rather than showing everyone who lives there, this map sacrifices overall diversity to instead show simple majorities. That makes it less racially precise than the famous racial dot maps that have been floating around the internet in recent years.

But the dot maps are too cluttered to show buildings, so making that racial tradeoff allows this map to illustrate the built environment too. It’s a good way to show two disparate pieces of information at the same time.

What pops out as interesting to you?

Accounting for population, the world map looks totally different

This is a world population cartogram, a false-geography map that resizes countries according to their population. It’s an interesting way to view the world, and compared to common projections perhaps more accurate, in its own way.


Map from Reddit user TeaDranks.

The United States is the world’s fourth largest country by land area, and third largest by population, so it’s not particularly distorted compared to geographic projections. But many other countries are.

China (1.4 billion) and India (1.3 billion) visually dominate, being by far the world’s two most populous countries. Others that stand out with seemingly oversized populations are Nigeria, Bangladesh, Japan, and the Philippines.

On the other end of the spectrum, the world’s two largest countries by land area are much reduced. Russia’s population of 146 million is still good enough for 9th highest globally, but that appears unimpressive against its normally huge area. And Canada, the world’s second largest country but only its 37th most populous, is nothing but a tiny sliver.

What stands out to you?

Australia has an enormous nationwide beltway

Washington’s I-495 beltway is a 64 mile long loop. London’s M-25 orbital motorway is 117 miles. They seem big, but they’re practically microscopic next to the greatest ring road on Earth, Australia’s 9,000-mile Highway 1.


Map from the Commonwealth of Australia.

In fact, Highway 1 is the longest single highway in the world. It’s 32% longer than Russia’s Trans-Siberian Highway, and almost three times longer than the longest US Interstate, I-90.

The Australian government created Highway 1 in 1955, by compiling a network of existing local and regional highways under a single banner.

Unlike American Interstates, Highway 1 isn’t fully limited access for its entire length. Near big cities like Sydney or Melbourne it looks like an Interstate, but many sections in rural areas are simple two-lane roads, and some extremely isolated sections are even more basic.

All hail the king of ring roads.

How fast can you go? Map of maximum speed limits around the world

In most of the United States, the maximum speed limit is somewhere between 65 and 75 miles per hour. What about the rest of the world? This map tells you.


Maximum speed limits around the world. Map from Reddit user worldbeyondyourown.

In the eastern US, most states top out with maximum speed limits of 70 miles per hour. Out west, most states allow 75, and a handful go even higher than that.

Texas has the highest speed limit in the western hemisphere, at 85 miles per hour. On the other end of the spectrum, no road in Canada’s province Nunavut has a limit above 45 miles per hour.

Germany’s Autobahn famously has no maximum speed limit, but it’s not the only place in the world to hold that distinction. Australia’s Northern Territory is also speed limit free. But don’t try racing down roads in Bhutan, where the maximum limit is no higher than 45.

What else jumps out?

Two maps that explain what DC might look like as a state

On Monday, Congress considered DC statehood. But what would DC actually look like if it became a state?


Maps by Geoffrey Hatchard for Neighbors United for Statehood.

The most likely path to statehood for the District would shrink the federal city to a tiny section surrounding the National Mall and other federal properties. That section would remain not part of any state. The rest of the city would then become the 51st state, possibly called New Columbia.

Here’s a zoom-in to what would become the remaining federal city.
