• What will driverless electric cars mean for cities?

  Yesterday I posted a video about the career of Elon Musk. And it reminded me of something that’s been on my mind as I think about transportation, cities, and the future.

  Elon’s story for why he founded SolarCity, Tesla, and SpaceX is incredibly compelling. He chose problems and industries that he felt would move humanity forward. He felt that we needed sustainable forms of energy production (SolarCity), sustainable forms of transport (Tesla), and a way for humans to occupy other planets (SpaceX). That’s incredible ambition.

  Today though, I just want to focus on the transportation piece.

  Electric and driverless vehicles, I believe, are a step in the right direction. I honestly believe that at some point in the not too distant future we’re going to look back at that time when people used to drive their own cars and wonder how we ever allowed that to happen.

  But fundamentally, I think there still remains a question of how best to plan our cities. 

  There’s lots of talk today about peak car and the death of the automobile. Certainly within planning and urbanist circles, there’s an almost universal belief that planning (most of) our cities around the car, as opposed to people, was a huge mistake. Multimodal solutions with a public transit backbone are now the way forward.

  But will that always be the case as the notion of the “car” evolves?

  Intuitively, driverless vehicles feels like a massive opportunity to leverage data and better optimize our private transport assets. We know that the utilization rate for most private cars is incredibly low and so there’s lots of room to improve how we use and share private vehicles and how we move people around cities.

  But how big is that opportunity? Does a city filled with driverless electric vehicles and with networks like Uber mean that public transportation now becomes less important? And if so, how much less important?

  I can’t help but feel like private and public transport are on a collision course right now. I suppose that isn’t anything new. But this time around I wonder if private transport won’t figure out a way to achieve similar efficiencies to large scale public transport.

• Did we hit peak car?

  

  The total number of vehicle miles traveled in the US used to largely do only one thing: go up. This is made it fairly easy for the Federal Highway Administration (FWHA) to forecast how much more Americans were going to drive in the coming years – they just extended the trend line.

  Below is what that looked like since the early 1970s (via FRED Economic Data). You’ll see that the total vehicle miles traveled went from somewhere around 1.1 trillion miles to around 3 trillion miles in and around the late 2000s. The shaded areas represent recessionary periods.

  

  But then in 2007, something happened. Total vehicle miles traveled peaked, declined, and then flat lined at just under 3 trillion miles. Here’s what that looked like (the ending time period is October 2014):

  

  However, since this was new for the FHWA, they continued to believe that this would ultimately correct itself and that total VMTs would eventually continue on their linear ascent. So here’s what their projections looked like (via State Smart Transportation Initiative):

  

  Clearly things didn’t go as planned.

  But then in May of last year (2014), the FHWA finally changed its tune and released this forecast, which had the following projections:

  

  It outlined 3 economic scenarios: a pessimistic one, a baseline one, and an optimistic one. In their baseline outlook, they believed that the annual growth rate for total vehicle miles traveled in the US would be 0.75% over a 30 year period running from 2012 to 2042.

  At the same time, they also stated that population growth would average about 0.7% per year through this same period. This means that the FHWA has more or less conceded that total vehicles traveled per person will likely remain flat, which is a significant change from previous forecasts.

  Now, given their track record, I don’t think any of us should put a lot of faith in the accuracy of these numbers. Per capita driving could flat line. But it might also go down, which is what it has been doing over the past few years.

  Either way, I do think it’s worth thinking about this shift. It’s a pretty big deal.
