Uber vs. Taxi (in New York)

I just spent the weekend back in my hometown of Philadelphia and while we walked most places, there were a few Uber rides. As someone who doesn’t use the app and normally will hail a taxi when necessary, I had been looking forward to posting this piece. FiveThirtyEight looked at data for New York comparing Uber to taxis.

Night Tube

Transport for London (TfL), the organisation that runs the London Underground or Tube, has announced a nighttime service called Night Tube. It is not for the entire system, but only a few specific lines. That means that TfL needed a new map. And that means that everyone will want to create their own version of the Night Tube map. So this article at City Metric looks at just that. The TfL version is shown below.

The Curviest Tracks on the Northeast Corridor

If you remember a little while back, Amtrak No. 188 derailed in North Philadelphia at Frankford Junction. I covered it here and here. Well, the New York Times has analysed the Northeast Corridor to identify the curviest segments of track, excluding entrances and exits from stations. Perhaps as no surprise, Frankford Junction is right among the top segments.

Aircraft Cabin Flow

Today’s post looks at an illustration from the BBC about aircraft cabin flow. As I have flown on four aircraft in the last month—quite a lot for me—I do recall thinking during one particular flight just where the air intakes were on the aircraft. It never dawned on me that they were in the actual engines themselves.

I think from a design side the only thing I would change is the width of the line for the airflow. That would show how while some is released, replacement air comes from the air mixing unit.

Illustrating a Table

Let’s face it, lots of people think tables are boring. They convey data very quickly and very efficiently. But they often don’t look “pretty” enough. So, today, I just wanted to show a table from the Washington Post from last week.

It does nothing fancy. Nor do the illustrations actually communicate the information more quickly or more clearly. But, look! Green clocks and charging stations!

Others’ Coverage of Amtrak 188

Tuesday I posted my late-night work on Amtrak No. 188’s derailment, (now with a few minor updates, including the speed information released this afternoon) so you could all get a sense of what happened yesterday. Of course, in the last 24 hours, we have seen a lot of news outlets covering the story.

The New York Times has a nice piece mapping out the details of the accident. Of particular interest, they included a map showing the parts of the Northeast Corridor equipped with positive train control. That is a system designed to prevent trains from exceeding their speed limits.

The Washington Post has two nice pieces. The first, below, incorporates both illustration to simplify the wreck site for the audience and then photographs to provide context of just how destroyed some of the train cars are, the first in particular.

The Post, however, also has a supplemental piece that looks at Amtrak’s accidents over the last ten years. This is the most data-centric piece of all that we are looking at, but that is okay. Most of the story is not reliant on data, but rather illustrations and diagrams trying to piece everything together.

Lastly, the BBC has an article with several small graphics looking at US train risks. Spoiler, American trains, while safe, are far less safe than those in Europe and Asia. Here, though, the map looks at accidents along the Northeast Corridor.

Amtrak Train No. 188 Derails

I am a big fan of trains, rail transit, and Amtrak. I think the rail network connecting the East Coast’s big cities from Boston down to Washington is one of the big draws of the Northeast. Not surprisingly, I have taken that route I don’t know how many times. So, when Amtrak’s Northeast Regional No. 188 derailed in Philadelphia, it ran off rails with which I am familiar.

I made a graphic tonight—so much for all my other plans—charting and mapping out what was announced by Philadelphia’s mayor, Michael Nutter. I am sure that by the time I wake up in the morning, we will know more and some things will have changed. But, let this be a simple guide to the basics as they were Tuesday night.

Frankford Junction is in the Port Richmond area of Philly. And what I can attest is that trains do slow down here, because it is a fairly sharp turn at a fairly flat grade (I think).

Parking in LA

Today’s piece comes via a colleague with the original article appearing in Wired. The article looks at new parking signs that the city of Los Angeles has proposed. The reason? Parking on streets with multiple signs for parking sometimes make no sense. These signs aim to simplify the communication of those parking regulations.

Germanwings Flight 4U 9525

Yesterday an Airbus A320 operated by Germanwings, a subsidiary of Lufthansa, crashed in the French Alps with no survivors. This morning, I am showing the two best graphics I have come across thus far attempting to explain just what happened.

The first is from the New York Times. In a series of maps, it points out through satellite photography the roughness of the terrain and therefore the difficulty likely to be experienced by recovery crews. The final line chart plots the altitude of the flight, which fell from a cruising altitude of 38,000 feet to just over 6,000 feet in eight minutes. Overall, especially given the limited amount of information that we currently possess, not a bad piece.

The second comes to us from the Washington Post. What I enjoy about this piece is that it combines the altitude chart with the map. This gives a bit context to the fact that despite being still 6,000 feet above sea level, the aircraft was in fact flying into the high mountains of the Alps.

Masses and Payloads

While last week ended with an xkcd post, I want to start this week with an older one I missed about spacecraft. Because spacecraft are awesome every day of the week. In particular it looks at mass and payload capacity of spacecraft and rockets over time.
