Strategic cycle network map, London

The strategic cycle network map

This is the capital's "strategic cycle network". The thick red lines are the existing routes - the Cycling Superhighways and Quietways, that have been spreading across the capital over the last few years. The thin red lines are those that are currently planned, and the green dotted lines are possible later connections.

If all this is delivered, the strategy says, 70 per cent of Londoners would live within 400m of a cycle route - a distance you can cycle in a couple of minutes.

Sheds and scaffolding of NYC

The de Blasio administration released an interactive map Wednesday showing the location of every sidewalk shed--the reviled wooden structures built to protect pedestrians from construction work happening above (or not).

The sheds, which are often referred to as scaffolding, have drawn the ire of New Yorkers because many owners leave them up for years. In 2016, Crain's looked into the billion-dollar scaffolding industry and the state law that created it and found that there were 190 miles of sidewalk sheds in the city. Some had been standing for well over a decade.

As of Wednesday, there were 7,342 sheds covering 290 miles, a 42% increase since 2016.

Regional infrastructure lines and metropolitan clusters

Are regional infrastructure lines and metropolitan clusters are more important than 'states' ?

Britain is also in the midst of an internal reorganization, with the government of Prime Minister David Cameron driving investment toward a new corridor stretching from Leeds to Liverpool known as the "Northern Powerhouse" that can become an additional economic anchor beyond London and Scotland.

Maps, pictures are data

Satellite photos provide a level of geographic specificity that national accounts do not. Another set of researchers used visual algorithms (related to those that recognize your face on Facebook or help navigate cars) to analyze these images pixel by pixel. Through this process, they could quantify poverty in each square kilometer of Uganda.

Satellite photos provide other useful information. In rural areas, we can see crops in the ground, allowing us to estimate harvest size -- even before the actual harvest. This data gives us a direct window into an essential part of the economic lives of many of the world's rural poor. The information can be used to build early warning systems for crop failure, to create crop insurance or target other forms of assistance.

There are many other important, unconventional sources of data. Consider cellphones. For most of the world's poor, each call and text has a very noticeable and real monetary cost.

Trumpers are American

The places where Trump has done well cut across many of the usual fault lines of American politics -- North and South, liberal and conservative, rural and suburban. What they have in common is that they have largely missed the generation-long transition of the United States away from manufacturing and into a diverse, information-driven economy deeply intertwined with the rest of the world.

Mind maps of cities, by Archie Archambault

Archie Archambault, a designer who's making an ongoing series called "Map From the Mind." Archambault's maps are based solely on his own explorations and time spent with locals in a given city. "It seems kind of dishonest to make a map completely based on secondhand data," he says. "The tradition of mapmaking is surveying and being within the parameters of the space."

Shape of city blocks

Travel to any European city and the likelihood is that it will look and feel substantially different to modern American cities such as Los Angeles, San Diego, or Miami.

Ref: A Typology of Street Patterns

The reasons are many. Most older European cities have grown organically, usually before the advent of cars, with their road layout largely determined by factors such as local geography. By contrast, the growth of many American cities occurred after the development of cars and their road layout was often centrally planned using geometric grids.

But while the differences are stark to any human observer, nobody has succeeded in finding an objective way to capture the difference. Today, that changes thanks to the work of Rémi Louf and Marc Barthelemy at the Institut de Physique Théorique about 20 kilometers south of Paris. They have found a way to capture the unique "fingerprint" of a city's road layout and provide a way to classify and compare the unique layouts of cities all over the world for the first time.

Louf and Barthelemy began by downloading the road layouts from OpenStreetMap for 131 cities from all continents other than Antarctica.One objective way to assess road layout is to think of it as a network in which the nodes are junctions and road segments are the links in between.

The problem with this method is that the networks of most cities turn out to be remarkably similar. That's because the topology captures the connectedness of a city but nothing about the scale or geometry of the layout. It is the scale and geometry of the layout that seem to be the crucial difference between cities that humans recognize.

Louf and Barthelemy's breakthrough was to find a way of capturing this difference. Instead of examining the road layout, they look at the shapes of the spaces bounded by roads. In other words, they analyze the size and shape of the street blocks.

In a city based on a grid, these blocks will be mostly square or rectangular. But when the street layout is less regular, these blocks can be a variety of polygons.

Capturing the geometry of city blocks is tricky. However, Louf and Barthelemy do this using the ratio of a block's area to the area of a circle that encloses it. This quantity is always less than 1 and the smaller its value, the more exotic and extended the shape. The researchers then plot the distribution of block shapes for a given city.

But this shape distribution by itself is not enough to account for visual similarities and dissimilarities between street patterns. Louf and Barthelemy point out that New York and Tokyo share similar shape distributions but the visual similarity between these cities' layouts is far from obvious.

That's because blocks can have similar shapes but very different areas. "If two cities have blocks of the same shape in the same proportion but with totally different areas, they will look different," they say.

So the crucial measure that characterizes a city combines both the shape of the blocks and their area. To display this, Louf and Barthelemy arrange the blocks according to their area along the Y-axis and their shape ratio along the X-axis. The resulting plot is the unique fingerprint that characterizes each city.

When they did this for each of the 131 cities they had data for, they discovered that cities fall into four main types (see diagram above). The first category contains only one city, Buenos Aires in Argentina, which is entirely different from every other city in the database. Its blocks are all medium-size squares and regular rectangles.

Better track geography and know where stories are being published and talked about

Going forward, this study provides an interesting foundation for thinking about how our media are interrelated, and how various facts, anecdotes, and bits of misinformation make their way to the public.

"Can we start exploring the data not from identifying these topics of keywords upfront, but asking an algorithm to surface some of those for us?" asks Graeff. "What are some unusual things or clusters of news stories that will allow us to get a sense of news stories that otherwise wouldn't be seen?"

In the future, Graeff says he'd like to be able to better track geography and know where stories are being published and talked about. The team is also interested in using natural language processing to track the spread of quotations from source to source. In addition, "automated coding and sentiment analysis" could be used to better understand how perspectives in the newsroom are molding stories -- tools like OpenGender Tracker.

Ultimately, the goal is to create a suite of tools that activists, journalists, and academics can learn from. Says Graeff: "A lot of what we show here is that there are better methods for studying the media as a so-called media ecosystem that allow us to really understand how a story goes from barely a blip to a major national/international news event, and how controversies circle around that."

Uber #2

Taxi officials say that Uber's service may not be legal since city rules do not allow for prearranged rides in yellow taxis. They also forbid cabbies from using electronic devices while driving and prohibit any unjustified refusal of fares. (Under Uber's policy, once a driver accepts a ride through the app, no other passenger can be picked up.)

Cabbies using the Uber app receive a smartphone loaded with its technology, which tries to predict areas where rides are in high demand. The driver nearest to a requested pickup location receives a notification and is given 15 seconds to respond.

Travis Kalanick, Uber's chief executive, rejected criticisms that the service violated city rules against prearranged yellow-taxi rides. "Prearrangement means it's basically on behalf of a base," he said in an interview. "We're not working with a base."

David S. Yassky, the chairman of the commission, said only that the city had "led the country in terms of putting new technology to work for riders" and noted that the commission was currently requesting proposals for a smartphone-based payment system.

At the meeting, officials raised concerns about a regulatory issue that would prevent Uber from processing credit cards for taxi rides, according to Mr. Kalanick.

Mr. Kalanick said he had agreed to make the app's new services available for no charge for the next week, so that riders could "get a taste of the future," while the two sides try to resolve the regulatory concerns.

Uber is one of several start-ups, like Taxi Magic and GetTaxi, trying to profit by connecting drivers and passengers more efficiently. Another company, Hailo, said it had already registered 2,500 drivers to use a similar service that it planned to unveil in the coming weeks.

Wayfinding by chirping sparrows in Penn Station

Q. Every time I wait in the Long Island Rail Road section of NYC Pennsylvania Station, I hear chirping, tweeting birds. The sound is louder near overhead speakers, so I'm assuming it's a recording. Is it supposed to make passengers calmer, like Muzak?

A. You are hearing a "talking kiosk," designed to help visually impaired passengers and others navigate the confusion of the station. The kiosk is in the Long Island Rail Road's main concourse, between the entrances to Tracks 14 and 15.

"To help visually impaired customers locate the kiosk, it emits the song of the lark sparrow (Chondestes grammacus), a bird species native to the American West, that is found by audiologists to have a unique set of phonetic properties considered effective for directional way-finding," said Susan McGowan, a spokeswoman for the railroad.

The current model was installed in December 2008, replacing an older one that also chirped. This one features a touch-activated tactile map of the station, visual displays for the partially sighted, and a voice designed for phonetic clarity, Ms. McGowan said in an e-mail message. As a customer touches different parts of the map, the kiosk describes the location and gives directions. It also offers general information about Penn Station and the Long Island Rail Road.
