• We are all selfish bastards

  We are all selfish bastards when it comes to sharing road space and public space.

  When we drive, we complain about pedestrians jumping out in front of us, crazy cyclists who get in our way, and under-utilized bike lanes that are taking away valuable driving space and creating traffic jams.

  When we take surface transit (such as buses and streetcars), we want all the cars out of the way so that we can move more efficiently. And we complain about drivers who don’t stop to let us off and on when the streetcar doors open. (Toronto specific reference.)

  When we cycle, we complain about cars parked in the bike lanes, people who don’t look before changing lanes or opening their car doors, and drivers who honk at you because they just want you off the road and onto the sidewalk.

  And when we walk, we complain about cyclists who ride on the sidewalk (they should be on the road!), cars that don’t stop to let us go, and slow walking groups who linearly block the entire sidewalk so you can’t pass.

  We are never happy. And we automatically assume that we could do it better. (I know I’m guilty of this.)

  But here are a few things to consider the next time you’re flipping the bird to someone on the streets. Here are a few things that we do know about urban mobility.

  There is an unprecedented number of condominiums in the development pipeline right now in Toronto. For argument’s sake, let’s assume 75,000 condominium suites – many of which will be built in central areas of the city.

  At a parking ratio of 0.6 stalls per unit, which isn’t an unreasonable assumption today, that’s 45,000 new parking spots and potentially 45,000 new cars in the city. 

  If you think that 45,000 new cars will be able to get fully absorbed into the core and somehow move around in an unfettered way, then I believe you are mistaken. 

  If you think that there’s something that can be done to magically expand road capacity to handle all of these additional cars in the city, then I believe you are mistaken.

  And if you think that adding a bike lane is the only reason you are currently stuck in traffic, then I believe you are missing the bigger picture.

  Over a decade ago, we made a decision in this region to encourage building up, instead of building out. And along with that decision came a necessary rethink of how we get around. That transition is what we are living through right now.

  The other thing we know is that the 4 modes of mobility that I started this post with are ordered from least sustainable to most sustainable. 

  Electric self-driving vehicles will reduce the impacts of driving, but it will also transform it into something that feels more like transit and less like the driving we know today. That will be a very good thing.

  But I’m not yet convinced that it will solve all of our problems. To do that I think we will need to adopt a much more balanced and unselfish view of what it takes to move around a city. That, of course, isn’t always easy.

• Making alpha-bets

  

  https://500px.com/embed.js

  On Monday, Google broke the internet when it announced that it was reorganizing itself into a holding company structure called Alphabet.

  That means that Google, Inc. will now become a subsidiary, along with many other companies, of Alphabet Inc. and all shares of Google will automatically convert into the same number of shares in Alphabet.

  This is huge, but also something that was likely inevitable given the passions of the founders. Apparently Larry Page has been thinking about this move for years.

  As it stands pre-Alphabet, Google (with its main internet products) is basically a cash cow funding all of Google’s other experiments. But this muddied the waters and made it difficult for investors to clearly see how much the main internet products were making and how much the founders were spending on self-driving cars, delivery drones (Project Wing), and other new ideas.

  Now everything will be separate.

  But what’s really exciting about the reorganization is that it sets the stage for Alphabet/Google – which is arguably already one of the most important companies in the world – to become even more impactful in a wide variety of industries and disciplines, some/many not traditionally associated with tech. Each wholly owned subsidiary will have their own CEO and the founders rightly believe, I think, that this overall structure will afford them more “management scale.”

  Within Google will remain search, advertising, maps, YouTube, and the Android mobile operating system. But already Alphabet is the parent company of the following other businesses:

  • Calico, an anti-aging life extension company
  • Sidewalk, a smart cities company whose mission is to improve life in cities
  • Nest, an “internet of things” company that makes connected devices for your home
  • Fiber, a company that offers super fast internet
  • Google Ventures (venture capital) & Google Capital (private equity)
  • Google X, which is the lab developing self-driving cars and delivery drones (Project Wing)

  If you can’t tell, I’m bullish on all of this. The approach really resonates with me and I can’t wait to see what Alphabet becomes. If you’d like to read the full and official blog post announcement, click here. 

  Cheers to trying new things and making big bets.

• Driverless cars, urban mobility, and Toronto’s Gardiner Expressway

  

  About a week ago I wrote a post questioning what driverless cars will mean for cities. I ended by saying that that it feels as if we’re going to see increasing tension between private and public transport.

  What I meant by that was simply that conventional notions around private car use are going to change. And ultimately that is going to mean that we need to rethink public transport and how that fits into a broader urban mobility framework.

  What do I mean by this?

  The International Transport Forum at the OECD recently published a fascinating report called, Urban Mobility System Upgrade: How shared self-driving cars could change city traffic. And it deals with exactly the sorts of things I am thinking about.

  The study looked of what might happen when all cars become self-driving in a mid-sized European city (specifically Lisbon, Portugal). They leveraged existing transportation data from the city, but replaced 100% of the human powered cars with two types of self-driving cars: TaxiBots and AutoVots.

  TaxiBots were driverless cars that would be shared with multiple people at the same time. In other words, they were a kind of pseudo-public transit. And AutoVots we’re your more conventional private taxi. They picked up one person at a time.

  So, what did they find?

  In the first scenario, they combined their TaxiBots and AutoVots with public transit (light rail) and discovered that the same number of people could be moved around with only 10% of the cars currently on the road. That’s a 90% reduction!

  They also found that the city needed 20% less on-street parking and 80% less off-street parking since driverless cars don’t need to sit idle waiting for a driver.

  In the second scenario, they removed mass transit from the equation. And in this instance they found that the city was still able to get around, but with an 80% reduction in the number of cars on the road. Remarkably, it also led to a 10% reduction in rush hour commute times.

  These are pretty profound changes. Reducing the number of cars on the road by 80-90% is a significant change. 

  But it’s also why I’ve been thinking about the tension between private and public transport. As we get better at optimizing “cars” (their definition will change), what becomes the role of true public transit?

  Ultimately, I think what will happen is a blurring of the two. In the example above, the TaxiBots served basically as small scale public transit. But that does not necessarily mean that true mass transit will become irrelevant. We’re just going to need to rethink how the entire mobility network fits together.

  I’d now like to bring this discussion back to Toronto for a minute.

  As many of you probably know from this blog, Toronto is on the cusp of deciding what to do with the eastern portion of the Gardiner Expressway (an elevated highway that runs across the downtown waterfront). It will go to City Council next month. 

  I firmly believe that we should remove it, but there many people who believe we shouldn’t. The main objection seems to be that the traffic projections indicate that removing it could make commuting into downtown – by car – 3 to 5 minutes longer by 2031. 

  By today’s standards, I believe this concern represents an outdated way of thinking about cities and urban mobility. Adding more lanes is like loosening your belt to deal with obesity. However, it gets even worse when you think about urban mobility in the context of this post.

  Given the profound transportation changes that are currently underway, I think there’s a strong likelihood that the Gardiner projections we have today will be completely wrong by 2031. I don’t know know for sure, but I’m guessing the models don’t account for the efficiencies being created by driverless cars and peer-to-peer networks.

  In other words, I am suggesting that those 3 to 5 minutes could prove to be a red herring. The relevant question should be: Which decision will allow Toronto to build the absolute best waterfront in the world? And in my opinion that leads to removing the Gardiner East.

  If you feel similarly, I would encourage you to write your local City Councillor.

• More thoughts on driverless cars

  

  If you’re a regular reader of Architect This City, you’ll know that I’m a big supporter of public transit. And that’s because, as far as I can tell, it’s the most efficient way of moving lots of people around a big city.

  But more and more I’ve been thinking about how technology might change, or even disrupt, this school of thought. Which is why when I wrote this post a few days ago, I was careful to say that private cars aren’t the mobility answer. Because in reality, cars likely aren’t going to go away. We’re just going to use them differently.

  Here are the two things I’m thinking about most:

  1. Driverless cars

  I’ve written about driverless cars before in terms of how they might be used as a form of public transit. But I think it’s worth revisiting them for a moment. There are lots of driverless car critics out there and they usually fixate on the fact that a car is still a car, whether or not you happen to be driving it. It still takes up the same amount of space in our cities. Or does it?

  The key thing to keep in mind is that when we’re not longer driving the vehicle, it opens up lots of different possibilities in terms of how they might be used and also how they might be designed. I was watching this fireside chat with the founders of Google the other night and, for them, driverless cars offer the possibility of solving two big problems: traffic and parking.

  We know that parking takes up a lot space in our cities. But that’s really symptomatic of the fact that the utilization rate for most people’s cars is incredibly low. Most of the time a car is sitting parked and idle. But with driverless cars, they’ll be able to drop you off at your destination and then continue on to pick up their next ride–thereby minimizing the need for all that parking.

  This would bring the utilization rate way up for each car, which would also minimize the number of absolute cars that we’d need to have in our cities to move everybody around. Of course, this would mean that we’d be sharing cars. People wouldn’t own cars; they would be an on-demand service.

  2. Networked vehicles

  This brings us to my second point: driverless cars will be networked cars. Again, I’ve written about this before, but I specifically wanted to raise it again because of a new service that Lyft just launched in San Francisco called Lyft Line.

  The way it works is simple. You input where you’re going and Lyft will match you up with others who are going to more or less the same destination. The routes get shared and this brings down the costs to everyday use. It runs on the same principles as the on-demand minibuses I wrote about in Helsinki.

  But if you combine this with driverless cars, you’re starting to get at something incredibly interesting. Now all of sudden you’re getting the door-to-door convenience of private cars with many of the efficiencies of public transit.

  So in my mind, it’s very possible that platforms like Uber, Hailo, and Lyft could became major infrastructure backbones in a world of driverless cars. And if you think about it in this context, then I don’t think the valuations for these companies should seem all that surprising. These are potentially huge innovations.

  In the end, I don’t know how this will all shake out. I don’t think anybody does. I believe that strong public infrastructure (such as subways, light rail, and so on) will still be needed in big cities, but I’m starting to think that mobile apps and driverless cars will also form a big part of how we get around. Probably more so than most people think today.
