That year LA declared it was at “Peak Car!”
Last Updated on November 23, 2024 by Daily News Staff
Was there a time it was considered that “The City of Angeles,” had reached “Peak Car?”
I recently came across an article posted by the Metro Digital Resources Librarian on the Dorothy Peyton Gray Transportation Library and Archive web site run by Metro Los Angeles. The article talked about LA’s new obsession with the automobile and how it gained popularity, in the early 1920s.
Peak Car Era
Library researchers pointed out that notable resources concurred with this, including Scott L. Bottles’ Los Angeles and the Automobile: The Making of the Modern City, and Ashleigh Brilliant’s The Great Car Craze, How Southern California Collided with the Automobile in the 1920s.
The automobile was new and fresh, and also offered freedom to its owners, who realized that they could become more mobile and not rely solely on the massive LA street car network at the time. The number of vehicle registrations in Los Angeles had quadrupled in just an eight-year period from 1914-1922.
“Automobile use exploded as the passenger vehicle transitioned from a hobbyist’s pursuit to a relatively affordable means of getting around the sprawling region and beyond.”
Metro Librarian found out what was happening on the public transit side of the story when they found an article published in Electric Railway Journal titled “California and Her Tractions, Part II.“
MetroDigital Resource Librarian:
As one of several features titled “A Series of Articles on Salient Phases of the Electric Railway Situation,” author Edward Hungerford details the then current state of public transit in the Los Angeles area.
And within that overview, he interviews Paul Shoup, Pacific Electric Railways president and vice-president of Southern Pacific Company.
Hungerford documents Pacific Electric’s earnings in a recent six-month period, and asks Shoup “for the real translation of these figures.”
Shoup responds by stating:
“They mean that the peak of the competition of the automobile, publicly or privately owned or operated, has been reached out here — and passed. Not only is the rapidly rising cost of cars and tires and gasoline and oil beginning to deter the overenthusiastic motorists, but I think that the novelty of excessive motor riding also is rather wearing off. The hazards of driving on crowded highways are becoming more apparent and parking spaces in towns and cities more a question of doubt.
In addition to our great numbers of motor stage routes in every direction, we now have some 500,000 automobiles in California licensed for pleasure purposes, to which should be added the cars owned and operated by the 100,000 Easterners who come out here every winter. The competitive effect of all these cars has been, and still is, vast indeed. But we already can see in it a declining curve.“
Yes, you read that right, Shoup declared that personal vehicle usage had peaked and that it was on the decline.
Shoup explains that Los Angeles Railway profits were consistent with those of Pacific Electric, but acknowledges that “increases in both operating cost and taxes had gone ahead a little more than proportionately.” But he intimates that the rising cost of automobile operation (gas, tires) means that cars will cease their encroachment into transit’s share of mobility.
MetroDigital Resource Librarian:
This statement was part of an interview published in a national journal. Was he telling industry professionals what they wanted to hear? Did he want to assuage fears of rail employees that their jobs were going to disappear as more people purchased and used automobiles? Was he hoping that his perspective would turn into a self-fulfilling prophecy so he could remain atop Pacific Electric and Southern Pacific?

Metrolink Offers Fare-Free Rides for Earth Day 2026
LOS ANGELES — April 22, 2026 — In a continued push toward sustainable transportation, Metrolink will once again offer systemwide free rides on Earth Day, inviting commuters and travelers to leave their cars behind and explore a cleaner way to move across the region.
A One-Day Opportunity to Ride Free
On Wednesday, April 22, passengers can board any Metrolink train — including the Arrow service — without purchasing a ticket. The initiative is part of the broader celebration of Earth Day, encouraging environmentally conscious travel choices.
The fare-free program is designed to appeal to both regular riders and first-time users, particularly those navigating Southern California’s persistent traffic congestion and rising fuel costs.
Encouraging Sustainable Travel Habits
“Earth Day is a reminder that small changes, like choosing public transit over driving one day a week, can have a meaningful impact on our environment,” said Doug Chaffee, chair of the Metrolink Board.
With gas prices continuing to strain household budgets, the agency hopes the initiative will inspire more residents to consider rail as part of their regular commute.
Regional Connections Expand Access
Metrolink’s Earth Day promotion aligns with similar efforts by other Southern California transit providers. Riders can seamlessly connect to services operated by: LA Metro and the Orange County Transportation Authority, Riverside County Transportation Commission, San Bernardino County Transportation Authority and Ventura County Transportation Commission.
These partnerships extend the reach of fare-free travel across a six-county region, making it easier for riders to explore destinations without relying on personal vehicles.
Service Adjustments and Rider Tips
Passengers should note that trains will operate on a reduced weekday schedule, implemented earlier this spring. Despite the adjustment, all Metrolink lines and station cities remain in service.
For those planning a trip:
- No ticket is required — simply board the train
- Bikes are welcome, with capacity ranging from three bikes per standard car to nine in designated bike cars
- A curated destination guide highlights attractions within walking or biking distance of stations
Environmental and Economic Impact
Metrolink is also promoting its Personal Impact Calculator, a digital tool that allows riders to estimate how switching from driving to rail can reduce greenhouse gas emissions and lower fuel expenses.
A Broader Trend in Public Transit
Fare-free transit days have gained traction nationwide as agencies look to boost ridership and promote sustainability. Southern California’s expansive commuter rail network makes it particularly well-suited for such initiatives, offering a viable alternative to one of the country’s most car-dependent regions.
Bottom Line
Metrolink’s Earth Day promotion is more than a one-day free ride — it’s a strategic effort to shift commuter behavior, reduce environmental impact, and showcase the convenience of regional rail. For Southern Californians, April 22 presents a low-risk opportunity to rethink how they travel.

Drones paired with AI could help search‑and‑rescue teams find missing persons faster
AI-powered drones equipped with thermal and infrared imaging are transforming search-and-rescue operations, enabling teams to locate missing persons faster and assess their condition—including signs of injury, consciousness, or life-threatening temperature changes—in real time.
Adeel Khalid, Kennesaw State University
A combination of infrared imaging, thermal imaging and color cameras on an uncrewed drone, along with an AI system to interpret the data, can help emergency responders and search-and-rescue teams locate, identify and track people who have gone missing in the wilderness. The experimental system helps responders pinpoint where a missing person is and determine whether they are hurt or even alive.
People who get lost or hurt while exploring nature can become stranded for days. Rescue teams often use drones to look for the person or signs of their whereabouts. The small drone my colleagues and I built at my lab at Kennesaw State University flies autonomously using a grid search pattern. It sends live video and images to a ground station operated by the rescue team.
When the AI system finds a person, it analyzes images to determine whether the individual is upright or lying on the ground. It segments parts of the person’s body, identifying the person’s head and the body’s position. It then zeroes in on the forehead. It extracts forehead temperature readings, pixel by pixel, from the imaging data to estimate forehead temperature. We have two papers detailing these findings accepted for the American Institute of Aeronautics and Astronautics Aviation Forum 2026 conference.
Our AI model then assesses whether the person is conscious or unconscious and identifies abnormal temperatures that could indicate heat stress, hypothermia or other physical complications, or death – all vital information for a search-and-rescue team.
In field trials we have conducted, the system has provided consistent temperature readings of the heads of volunteers from our research team who have walked out into a variety of environments, under different conditions.
Why it matters
It is critical to get accurate and timely information on the whereabouts of a missing person. The likelihood that the person will survive decreases steeply as time passes.
An AI-enhanced drone can make search-and-rescue operations significantly more efficient than sending teams of people out into the environment to search on foot, especially in poor weather conditions or under thick foliage. Rescuers who know whether a person is conscious or unconscious can also better gear up for what they need to do to retrieve the person and administer aid. Our technology could save lives.
What other research is being done
Search-and-rescue personnel use various kinds of drones, but the machines often lack the ability to positively identify humans, especially under thick foliage, in bad weather or when the person is lying down or unconscious. The AI-based technology we have developed overcomes those challenges.
Better sensors that are very lightweight, that can function at night or in rain, and can see more clearly through thick foliage could further improve our drone and drones used by others. Researchers are devising AI-powered sound recognition for detecting screams for help, advanced thermal imaging for better nighttime vision and autonomous drones that could act as first responders.
Also under development are drones that can carry heavy payloads, such as flotation devices, fly for up to 14 hours or perform real-time mapping of the ground below.
What’s next
One of our next steps is to have multiple drones fly together and autonomously coordinate search-and-rescue operations among themselves. This will allow the technology to cover a much larger area, perhaps hundreds of square miles.
We are also designing a large drone that can carry up to 110 pounds (50 kilograms) of payload and stay aloft for an hour.
The Research Brief is a short take on interesting academic work.
