It has become fairly common to blame Uber (and ridesharing in general) for increased traffic congestion. I hear it all the time: “If only there weren’t so many Ubers on the road, traffic would flow more freely.” While there are studies suggesting that “deadheading” miles do have a negative impact and that Uber can draw people away from public transit (that’s bad), I think it’s important to consider the bigger picture here. So let’s try and do that today.
Firstly, let’s think about who traffic congestion directly impacts (indirectly it’s everyone). If you’re a pedestrian, you don’t care about traffic congestion. In fact, maybe you gain satisfaction from seeing other people stuck in it. (There’s even a German word for this feeling.) Similarly, if you’re riding the subway, taking any form of transit on its own right-of-way, or riding a bike, you likely also don’t care about traffic congestion. It doesn’t directly impact you.
Where you do care about congestion is if you’re in something like a bus that is stuck in traffic or if you’re driving. In the former case, you’re probably thinking, “hey why can’t these people take the bus like me. Then we’d have less traffic!” And in the latter case you’re probably thinking, “if only there weren’t so many Ubers and bike lanes, then I wouldn’t be stuck in traffic!” Ironically, this is arguably the biggest segment of people who feel they are being impacted by Ubers.
Secondly, let’s think about how Uber vs. driving might impact traffic congestion differently. In both cases, I would think that the majority of use cases involve one person (excluding drivers in the case of Uber) going to their desired destination. So from a raw space per person perspective, they both take up a similar amount of urban space.
The differences are that the Uber likely had some amount of deadhead miles. In other words, it spent time driving around looking for its next passenger. And it likely targeted already busy areas because that’s where it was more likely to find someone. Individual drivers don’t do this. They go from point A to point B.
However — and this is a big however — drivers do require parking once they get to where they’re going. Ubers don’t. This both takes up more space and oftentimes requires some amount of circling around. This is a significant difference and it begs the question: which is worse? Deadhead miles or all of the parking that cars generally require? I would argue the latter.
Where I’m going with all of this is that I think the criticism of Uber is misdirected. It doesn’t get at the real underlying problem. If traffic congestion exists, it is because they are too many cars for a finite amount of road space. This includes the people who choose to drive themselves around. In fact, you could argue that they’re the most impactful to cities. The way you solve this is simple: you price congestion and you encourage alternative forms of mobility.
Everything else is just a distraction.
