Reveal How New York Has Changed With This 'Scratch-Off' Map

Cities never look the same for more than a few years in a row. Landmarks disappear, elevated trains give way to streetcars and subways, and old industrial sites get rehabbed, to name a few common changes. Over the past century, a fair amount has changed in New York City, as evidenced by a new application that compares the modern city to its 1924 past.

Urbanist and data visualization enthusiast Chris Whong created Urban Scratch Off, a simple site with two layers of maps—one from 1924 and one from today—that allows users to erase one layer to reveal the imagery beneath. While much of the city’s broad design looks quite similar in structure to its 1924 incarnation, some infrastructure projects have made big impacts.

Whong’s original concept was to visualize the impact the Brooklyn-Queens Expressway had on the communities in its path, and the level of demolition that occurred to make way for the highway. But once you start scratching off parts of the city to reveal the historical urban fabric, it’s hard to stop at just the path of one highway. So he made it into a city-wide visual of urban development over 90 years.

Since 1924, waterfronts have changed (Battery Park City, a landfill site in downtown Manhattan, was completed in 1976), stadiums have moved (the current Yankee Stadium is a block north of the original, and the original home of the Brooklyn Dodgers is now an apartment building), and major airports have been erected (JFK opened as New York International Airport in 1948). Just draw your mouse over a location to see what it looked like before versus what it looks like now.

Whong hopes to add points of interest in the future, because without a search function, it’s a little hard to find specific places unless you’re super familiar with the geography. Play with it for yourself here. It’s like a virtual lottery scratcher, except you don’t lose any money.

Design
These LED Crosswalks Adapt to Whoever Is Crossing

Crosswalks are an often-neglected part of urban design; they’re usually just white stripes on dark asphalt. But recently, they’re getting more exciting—and safer—makeovers. In the Netherlands, there is a glow-in-the-dark crosswalk. In western India, there is a 3D crosswalk. And now, in London, there’s an interactive LED crosswalk that changes its configuration based on the situation, as Fast Company reports.

Created by the London-based design studio Umbrellium, the Starling Crossing (short for the much more tongue-twisting STigmergic Adaptive Responsive LearnING Crossing) changes its layout, size, configuration, and other design factors based on who’s waiting to cross and where they’re going.

“The Starling Crossing is a pedestrian crossing, built on today’s technology, that puts people first, enabling them to cross safely the way they want to cross, rather than one that tells them they can only cross in one place or a fixed way,” the company writes. That means that the system—which relies on cameras and artificial intelligence to monitor both pedestrian and vehicle traffic—adapts based on road conditions and where it thinks a pedestrian is going to go.

If a bike is coming down the street, for example, it will project a place for the cyclist to wait for the light in the crosswalk. If the person is veering left like they’re going to cross diagonally, it will move the light-up crosswalk that way. During rush hour, when there are more pedestrians trying to get across the street, it will widen to accommodate them. It can also detect wet or dark conditions, making the crosswalk path wider to give pedestrians more of a buffer zone. Though the neural network can calculate people’s trajectories and velocity, it can also trigger a pattern of warning lights to alert people that they’re about to walk right into an oncoming bike or other unexpected hazard.

All this is to say that the system adapts to the reality of the road and traffic patterns, rather than forcing pedestrians to stay within the confines of a crosswalk system that was designed for car traffic.

The prototype is currently installed on a TV studio set in London, not a real road, and it still has plenty of safety testing to go through before it will appear on a road near you. But hopefully this is the kind of road infrastructure we’ll soon be able to see out in the real world.

Tokyo Tops List of Safest Cities in the World, New Report Says

When choosing a city to call home, some might weigh factors like affordability, potential for job growth, and even the number of bookstores and libraries. But for many aspiring urbanites, safety is a top concern. This list of the world’s safest cities from the Economist Intelligence Unit (EIU) proves you don’t need to trade your sense of welfare for the hustle and bustle of city life—especially if you're headed to Tokyo.

As Quartz reports, the EIU assessed the overall safety of 60 major cities using categories like health safety, infrastructure safety, personal safety, and the cybersecurity of smart city technology. With an overall score in 89.80 out of 100 points, Tokyo is the 2017 Safe Cities Index's highest-ranking city for the third year in a row.

While it was rated in the top five places for cybersecurity, health security, and personal security, Tokyo's No. 12 spot in the infrastructure security category kept it from receiving an even higher score. The next two spots on the EIU list also belong to East Asian cities, with Singapore snagging second place with a score of 89.64 and Osaka coming in third with 88.67. Toronto and Melbourne round out the top five. View more from the list below.

1. Tokyo
2. Singapore
3. Osaka
4. Toronto
5. Melbourne
6. Amsterdam
7. Sydney
8. Stockholm
9. Hong Kong
10. Zurich

You may have noticed that no U.S. cities broke into the top 10. The best-rated American metropolis is San Francisco, which came in 15th place with a score of 83.55. Meanwhile, New York, which used to hold the No. 10 slot, fell to No. 21 this year. The report blames the U.S.'s poor performance in part on America's aging infrastructure, which regularly receives failing grades from reports like these due to lack of maintenance and upgrades.
