U.S. commuters take roughly 10 billion journeys on public transit yearly. SciLine requested Kari Watkins, an affiliate professor of civil and environmental engineering on the University of California, Davis, what cities can do to extend public transportation ridership and the way folks could make higher use of this environmentally pleasant mode of transportation.
Below are some highlights from the dialogue. Answers have been edited for brevity and readability.
Why is transit a sustainable mode of transportation?
Kari Watkins: Economically, it’s simpler on folks’s pocketbooks. Environmentally, transit has much less emissions per journey.
From an fairness viewpoint, transit is extra sustainable than different modes since you’re extra capable of serve all folks. This service is on the market – you don’t need to afford a automobile so as to have the ability to take it.
How does public transit have an effect on site visitors congestion?
Kari Watkins: We save about 24% of our congestion ranges by having transit in our 15 largest cities.
What has analysis proven us about transit’s security?
Kari Watkins: Transit is the most secure mode of transportation due to the skilled drivers and due to the character of how the providers are offered. They’re usually in their very own corridors with actually, actually excessive elements of security in how these corridors are designed.
When we have a look at cities the place extra folks take transit versus driving themselves, we at all times have decrease crash charges, each internationally and throughout the U.S.
What are some traits of ridership on public transit methods lately?
Kari Watkins: Over the previous roughly 5 years earlier than COVID, we had been seeing declines in each bus and rail in ways in which we had not seen earlier than and couldn’t be attributed to issues like inhabitants decreases or decrease employment charges. We noticed declines that may very well be largely attributed to the rideshare corporations. Uber and Lyft had been taking a fairly heavy toll on transit ridership.
In addition to this, earlier than COVID, low fuel costs had been an element. When fuel costs go down, transit ridership goes to go down. And a bit little bit of will increase in fares on transit methods was additionally hitting transit ridership.
And then COVID hit.
What occurred throughout COVID was a number of the individuals who depend on transit on a day-to-day foundation – these crucial staff, people who had been maintaining our society going in the course of the early components of COVID – they nonetheless needed to get to work. And a lot of these people are bus riders versus rail riders, due to the way in which we’ve arrange these methods. And so we noticed bus ridership decline, but it surely was nonetheless at vital parts of what it was earlier than COVID.
Rail, however, was decimated, particularly commuter rail.
Most commuter rail companies are even nonetheless at this time nowhere near what they had been pre-COVID. In the early days of the pandemic, they had been at 10% of the ridership ranges that they as soon as had been.
We’re seeing some companies, like Los Angeles Metro, the place they’re predicting that within the subsequent yr or two, they’re going to be again as much as the degrees that they had been pre-COVID. But there’s a number of cities which have been completely hit, equivalent to San Francisco and New York.
Why are some transit companies dealing with a ‘fiscal cliff’?
Kari Watkins: What occurred throughout COVID was that many of those companies had been rescued by means of authorities applications the place they obtained additional working funds as a result of the federal authorities and state governments knew that these companies had been going to be dealing with such dramatic declines in ridership that they wouldn’t have the ability to present their providers with out some form of additional assist.
But all of that additional working funding is disappearing over time. And with some companies, they anticipate it’ll final one other yr, possibly two, however they’re unsure if their ridership is projected to be again on the identical ranges that it as soon as was.
How might transit turn into extra environmentally pleasant?
Kari Watkins: There’s really lots that may be completed to our system if we electrify transit additional. For a long time, we’ve had transit strains that had overhead methods to energy it, or a 3rd rail system, the place it’s powered from beneath, like our subway methods.
All of these are actually costly to construct. But battery know-how that’s coming round for our passenger autos can be coming round and enhancing tremendously for larger-scale autos, equivalent to vehicles and buses. This provides us the power to begin to electrify routes which might be working on pavement in streets. The hang-up is just that we now have to run these routes for a complete day and the window to cost them is only a small window in a single day.
