In tenuous link between my recent posts on automation, here and especially here, where back in November I discussed autonomous vehicles and their impact on employment. I also said:
While many cities are salivating over the ability of self-driving, autonomous vehicles to fix their broken road and transport infrastructure, that’s missing the point.
Sometime between then and last weekend I became a weekend subscriber to the (Boulder) Daily Camera, a great local paper for the Boulder/Denver metro area. Right on queue, my first Sunday paper was laying in the snow on the drive this weekend and I opened it up and parsed it during the day. One item that particularly caught my eye was Dave Kriegers main editorial entitled “Imagine a giant fleet of tiny buses“.
I grabbed a pen, marked the editorial up, scribbled in the margins and sat down on Monday morning and wrote an open forum letter. It didn’t get published, I have no idea if it’s policy not to publish corrections on staff written op-ed pieces, or they just didn’t think it interesting enough to include?
Since a big fuss has blown up about an Uber self driving car today, running a red light yesterday(in full transparency, Uber self driving development has a big office here in Louisville that is a build-up from the Uber acquisition of Microsofts Bing mapping service.) I thought I’d turn Mondays open forum letter into a blog post.
This also lets me correct one misstatement. Self-driving cars will help with congestion theoretically. In heavy traffic, they will drive at a regulation speed, a safe distance from the vehicle in front, thus avoid the hard braking and the impact that can have on several miles of traffic.
It is hard to respond to Dave Kriegers editorial imaging “a giant fleet of tiny buses” in 300-words, but I’d like to have a try.
First, I completely agree with his sentiment that if you keep trying the same old thing, you’ll keep failing. However, when it comes to his “giant fleet of small buses” he falls into the same trap most transport ‘imagineers’ do when the come to self-driving vehicles. For the sake of brevity, let’s assume they’ll be electric; let’s assume they can dock themselves; let’s assume they have a slightly better range than current electric cars.
Dave jumps to the conclusion that less space will be needed for parking. Sort of, except the cars have to be charged somewhere. But yes, they could be charged in either fields or reclaimed parking garages outfitted with self-docking chargers. Dave then makes the confusing jump to the conclusion that “[they] could reduce congestion because fewer cars would serve more people”.
Anyone that’s given any serious thought to scheduling and transportation would understand implicitly that that isn’t true. It’s implied because it fits the paradigm of autonomous vehicles. If 20,000 people want to get into Boulder today between 7:15am and 9:00am in their own unshared transportation, and the demand is the same in the era of self-driving cars, then, you’ll have the same number of journeys. Add in the recharging trips, the fact that using Daves logic, there will be less self-driving cars, then some of those cars will have to drive in and out and back into Boulder, actually increasing the number of journeys and therefore contributing to the congestion.
If we take Daves “less parking space” claim at face value, then what will the space formerly used by parking garages be used for? Green space… err no, more offices/accommodation, with the potential to further increase the number of journeys and congestion.
Don’t get me wrong, self-driving cars are great, but until we have flying cars they will only help indirectly with congestion
won’t help with congestion. The only way is shared transport. Bus Rapid Transport isn’t it either. Trams, street cars, metro-rail are the only real fix.
