How Ride-Hailing Could Improve Public Transportation Instead Of Undercutting It

Over the last half-decade, public transit ridership declined nationwide. The number of vehicle miles traveled in cars is rising, and traffic congestion is getting worse in many U.S. cities. At the same time, the century-old taxi industry is struggling, with many taxi companies going bankrupt.


Are ride-hailing companies such as Lyft and Uber to blame? What has been their impact and what should be done?

While ride-hailing threatens public transit, it is also key to its future success — but only with smart policies and the right price signals. As researchers working at the intersection of energy, the environment, and public policy, we have been analyzing transportation trends for decades — and seeing remarkably little innovation. Now we are on the cusp of major transformations. We see ride-hailing through the framework laid out in Daniel Sperling’s new book, “Three Revolutions: Steering Automated, Shared, and Electric Vehicles to a Better Future.”

More travel, less mass transit

Let’s start with the data. Public transit ridership dropped in 31 of 35 U.S. major metropolitan areas in 2017. It has declined by 3% since 2014, and 2017 was the lowest year of overall transit ridership since 2005.

Meanwhile, total U.S. vehicle miles traveled (VMT) has increased steadily since 2011. Most dramatically, Lyft, Uber, and other ride-hailing companies have soared, from near zero trips in 2012 to about 2.6 billion in 2017. As of 2016, 250 million people globally used ride-hailing apps, including 15% of the U.S. public.

Parsing the impacts of ride-hailing

As ride-hailing has grown, so too has the number of researchers working to understand its impacts. Experts at UC Berkeley, UC Davis, the University of Colorado, the University of Michigan, and Texas A&M University have all found that a significant fraction of ride-hailing customers would have traveled by transit, or opted against traveling at all, had ride-hailing been unavailable. This indicates that ride-hailing is displacing transit ridership and increasing vehicle miles traveled by cars.

Why is this happening? People are choosing ride-hailing because transit does not match the comfort and convenience offered by private vehicles, and taxis cannot offer the affordability and transparency of app-based ride-hailing. VMT is increasing as growing numbers of for-hire cars log “deadhead” miles driving to pick up passengers or returning from destinations. In New York City, unoccupied taxi and ride-hailing hours grew by 81% from 2013 to 2017.

But the net effects are highly region-dependent. Dense urban markets are responding differently than suburbs. In San Francisco, fully one-third of Lyft and Uber riders use ride-hailing in lieu of public transit. A survey in Denver found that 22% of respondents would have used transit had ride-hailing been unavailable. In contrast, researchers found that only 3% of Lyft and Uber riders in Austin switched to transit during a suspension of ride-hailing services.

Positive impacts too

While ride-hailing is pulling riders away from public transit in some places, it can also enhance transit ridership. The UC Berkeley survey found that 4% of Uber and Lyft customers ended their rides at transit stations, which suggests that they were using ride-hailing to connect to transit. Our colleague Caroline Rodier has observed that multiple surveys show about 5% of respondents relying on ride-hailing to access transit, although Rodier concluded that the increased transit trips are offset by the diversion of trips away from transit.

Local governments and agencies can work with ride-hailing services to enhance public transit instead of undermining it. For instance, ride-hailing can help smooth transportation demand shocks caused by temporary transit disruptions, such as closures of subway stations for maintenance.

What’s more, while ride-hailing may increase car-based travel, this is not necessarily a bad thing. More mobility increases access to jobs, health care, and education. And a significant percentage of ride-hailing trips occur late at night when congestion is not a big concern and transit options are not always available.

Indeed, its late-night popularity suggests that ride-hailing is removing some of the most dangerous type of vehicle miles. According to a UT Austin study of all 273 U.S. cities with a population of more than 100,000, ride-hailing services reduced fatal drunk driving crashes by 10-11%.

Ride-hailing also offers greater independence for elderly and disabled populations. The Center for American Progress observes that ride-hailing can help disadvantaged populations overcome geographic isolation and access jobs, education, and health care services.

Complementing public transit

For transit agencies, ride-hailing services can be an attractive alternative to serving sparsely populated, low-density areas with fixed routes and schedules. Private mobility companies and public transit agencies have launched nearly 50 pilot projects and partnerships to explore these opportunities. Many agencies are subsidizing travel in ride-hailing vehicles to meet the needs of certain rider groups.

In San Clemente and Dublin, California, officials canceled fixed-route buses with the lowest ridership and provided discounts for people to travel in Lyft and Uber. Phoenix is discounting the price of ride-hailing trips to and from 500 city bus stops. Denver is offering free rides to suburban light rail stations.

Reducing solo travel

The number of innovative transit partnerships is growing rapidly, but the jury is still out on what types of partnerships can yield win-wins for communities, companies, and transit agencies. An overarching goal should be to increase mobility — that is, passenger miles traveled — while reducing vehicle miles traveled.

This will only happen if ride-hailing services continue to shift toward multi-passenger services, such as Lyft Line and UberPool. Such a change will require policy frameworks that encourage shared rides and discourage single-passenger rides — starting with ride-hailing services and eventually including travelers using their own vehicles.

Road pricing practices, in which drivers pay fees to travel in high-use areas, have reduced traffic and increased pooled rides and transit trips in London, Stockholm, and Singapore. Importantly, Uber and Lyft embrace these strategies to expand pooling services and gain relief from stifling traffic congestion, just like the rest of us.

Pooling and road pricing will be especially critical with the coming vehicle automation revolution. If automated vehicles are individually owned, they will likely generate massive new vehicle use, since travel will no longer be seen as onerous. Occupants can sleep, eat, text, read, and watch videos while their cars do the navigating. But if those automated vehicles are pooled, then vehicle use would be pushed in the opposite direction, toward fewer vehicle miles traveled.

U.S. cities and transit operators have done little innovating in the past 50 years and are ill-prepared for the changes ahead. They need to decipher what is happening, build partnerships, and support price signals that encourage pooling. Acting to maximize the societal benefits of ride-hailing and other transportation revolutions will provide benefits now and into the future.

National Tell a Joke Day dates back to 1944 when President Franklin Delano Roosevelt was having a meeting with Vice-President, Henry Wallace. The two men were tired and depressed due to the stress caused by leading a country through world war.

During a lull in the meeting, Wallace said, "Frank, to cheer you up I have a joke I'd like to share."

"Let's have it, Henry," Roosevelt replied while ashing his cigarette.

"Why did the chicken cross the road?" Wallace asked. "Not sure," Roosevelt replied.

"To get to the other side," Wallace responded.

Roosevelt laughed so hard that the bourbon he was drinking sprayed out of his nose and onto the floor of the oval office.

The joke was so funny, and did such a great job at lightening both their moods, Roosevelt proclaimed that every year, August 16 would be National Tell a Joke Day.

Just kidding.

Nobody knows why National Tell a Joke Day started, but in a world where the President of the United States is trying to buy Greenland, "Beverly Hills, 90210" is back on TV, and the economy is about to go off a cliff, we could all use a bit of levity.

To celebrate National Tell a Joke Day, the people on Twitter responded with hundreds of the corniest dad jokes ever told. Here are some of the best.

The Judean date palm was once common in ancient Judea. The tree itself was a source of shelter, its fruit was ubiquitous in food, and its likeness was even engraved on money. But the plant became extinct around 500 A.D., and the prevalent palm was no more. But the plant is getting a second chance at life in the new millennium after researchers were able to resurrect ancient seeds.

Two thousand-year-old seeds were discovered inside a pottery jar during an archaeological excavation of Masada, a historic mountain fortress in southern Israel. It is believed the seeds were produced between 155 B.C. and 64 A.D. Those seeds sat inside a researcher's drawer in Tel Aviv for years, not doing anything.

Elaine Solowey, the Director of the Arava Institute for Environmental Studies at Kibbutz Ketura in Israel, wondered if she could revive the Judean Date Palm, so in 2005, she began to experiment. "I assumed the food in the seed would be no good after all that time. How could it be?" Solewey said.

There's been an uptick in fake emotional support animals (ESAs), which has led some airlines to crack down on which animals can and can't fly. Remember that emotional support peacock?

But some restrictions on ESAs don't fly with the Department of Transportation (DOT), leading them to crack down on the crack down.

Delta says that there has been an 84 percent increase in animal incidents since 2016, thanks in part to the increase of ESAs on airplanes. Last year, Delta airlines banned pit bulls and pit bull-related dog breeds after two airline staff were bitten by the breed while boarding a flight from Atlanta to Tokyo.

"We must err on the side of safety. Most recently, two Delta employees were bit by a pit bull traveling as a support animal last week. We struggled with the decision to expand the ban to service animals, knowing that some customers have legitimate needs, but we have determined that untrained, pit bull-type dogs posing as both service and support animals are a potential safety risk," Delta told People regarding the new rule.

Trying to get one dog to sit still and make eye contact with a camera for more than half a second is a low-key miracle. Lining up 16 dogs, on steps, and having them all stare at the camera simultaneously is the work of a God-like dog whisperer.

This miracle worker is Liam Beach, a 19-year-old animal management graduate from Cardiff, Wales. A friend of his dared him to attempt the shot and he accepted the challenge.

"My friend Catherine challenged me to try to get all of my lot sat on the stairs for a photo. She said, 'I bet you can't pull it off,' so I thought 'challenge accepted,'" he said, accoriding to Paws Planet.

Americans on both sides of the political aisle can agree on one thing: our infrastructure needs a huge upgrade. While politicians drag their feet on high-speed rail projects, fixing bridges, and building new airports, one amazing project is picking up steam.

The Great American Rail-Trail, a bike path that will connect Washington state to Washington, D.C., is over 50% complete.

The trail is being planned by the Rails-to-Trails Conservancy, a nonprofit that is working with local governments to make the dream a reality.
