The Sidewalk Weekly: what we're thinking, doing, and reading about the future of cities.

The tools that cities use to manage their intersections haven’t kept up with the times. The good old traffic light does a great job organizing complex car movement and optimizing for travel speed. It wasn’t built for the tasks of improving safety or moving people using other modes.

There’s no simple solution to crowded crossings, but many emerging technologies carry the promise of a more responsive intersection. Sensor arrays and computer vision can make detection of multiple street users readily achievable. Machine learning is becoming more capable of improving large, complex systems. On-site processing can enable more security and data privacy.

In a new Sidewalk Talk post (link), Willa Ng explains how this suite of technologies holds the potential to help cities manage their streets with the real-time judgement and adaptability of a traffic officer. This heightened awareness raises the hope of improving street safety while also helping all travelers instead of just drivers. More congested links:

What we're thinking

Why you don't build me up: In cities around the world, residential housing is still built today the same way it was 50 years ago. Unfortunately, we're not much better for the practice. A new report finds that construction productivity is lower now in the U.S. than it was in 1968 (CityLab). Bringing innovation to the construction industry isn't easy, and reducing building costs alone won't improve housing affordability in big cities, but reimagining the way we approach construction is a critical step in reducing cost of living.

Patient zero: It's never been easy to innovate in healthcare, but that hasn't stopped a growing number of start-ups and investors from trying. In a long look at the industry's ongoing "digital revolution," The Economist notes that the big winners from this movement should be not just patients who get better care but "those who avoid becoming patients at all" (link). As our Care Lab has noted, one approach to achieving that goal is using data to identify people who would benefit from non-medical interventions that can save hospital costs down the line (Sidewalk Talk).

What we're doing

Beyond L-mageddon: Last week we launched our NYC Transit Explorer map demo (Sidewalk Talk). The tool shows New Yorkers how long it takes to get anywhere in the city by bus or subway, as well as how commute times will change when the L train shuts down in 2019. If you haven't checked it out, please do! And if you have ideas for other features we should add, contact us through this Google Form. So far users have requested better integration with commuter rail, Citi Bike, and ADA compliance. We'll be gathering feedback and evaluating our ability to improve the tool over the short and long term. More map-tastic coverage:

  • Mapping Life Without the L Train (Streetsblog NYC)
  • L train shutdown commute times visualized with new tool (Curbed)
