Buses

Since the 1940s, there has been a broad shift away from public transit across the U.S., and service has declined in many cities, including New York, Boston, Denver, Orlando and St. Louis. A look back at the last national mass transit boom helps explain the challenges that confront modern transit agencies. Starting in the 19th century, transit companies worked closely with real estate developers to develop “streetcar suburbs” for a growing population. The companies kept fares low, thanks to corporate consolidation, government regulation and thrifty management. During World War II, producing weapons and supplies for troops fighting abroad became the nation’s top priority. Gasoline, tires and autos were strictly rationed, so most commuters had few ways to get to work other than public transit. In Baltimore, for example, people could ride a streetcar anywhere in the city in 1943 for 10 cents. With wartime production booming, the city’s Baltimore Transit C...

With the Olympic torch extinguished in Paris, all eyes are turning to Los Angeles for the 2028 Olympics. The host city has promised that the next Summer Games will be “car-free.” For people who know Los Angeles, this seems overly optimistic. The car remains king in LA, despite growing public transit options. When LA hosted the Games in 1932, it had an extensive public transportation system, with buses and an extensive network of electric streetcars. Today, the trolleys are long gone; riders say city buses don’t come on schedule, and bus stops are dirty. What happened? This question fascinates me because I am a business professor who studies why society abandons and then sometimes returns to certain technologies, such as vinyl records, landline phones and metal coins. The demise of electric streetcars in Los Angeles and attempts to bring them back today vividly demonstrate the costs and challenges of such revivals. The 2028 Olympi...

Public transit systems face daunting challenges across the U.S., from pandemic ridership losses to traffic congestion, fare evasion and pressure to keep rides affordable. In some cities, including Boston, Kansas City and Washington, many elected officials and advocates see fare-free public transit as the solution. Federal COVID-19 relief funds, which have subsidized transit operations across the nation at an unprecedented level since 2020, offered a natural experiment in free-fare transit. Advocates applauded these changes and are now pushing to make fare-free bus lines permanent. But although these experiments aided low-income families and modestly boosted ridership, they also created new political and economic challenges for beleaguered transit agencies. With ridership still dramatically below pre-pandemic levels and temporary federal support expiring, transportation agencies face an economic and managerial “doom spiral.” Free public transit that doesn’t b...

Public transit in the U.S. is in a sorry state – aging, underfunded and losing riders, especially since the COVID-19 pandemic. Many proposed solutions focus on new technologies, like self-driving cars and flying taxis. But as a researcher in urban policy and planning, I see more near-term promise in a mode that’s been around for a century: the city bus. Today, buses in many parts of the U.S. are old and don’t run often enough or serve all the places where people need to go. But this doesn’t reflect the bus’s true capability. Instead, as I see it, it’s the result of cities, states and federal leaders failing to subsidize a quality public service. As I show in my new book, “The Great American Transit Disaster: A Century of Austerity, Auto-Centric Planning, and White Flight,” few U.S. politicians have focused on bus riders’ experiences over the past half-century. And many executives have lavished precious federal capital doll...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to curiouskidsus@theconversation.com. Why do we use gasoline for small vehicles and diesel fuel for big vehicles? – Methdini, age 15, Sri Lanka Gasoline fuels most light-duty vehicles, such as passenger cars and pickup trucks. Heavy-duty vehicles, like buses, delivery trucks and long-haul tractor-trailers, typically run on diesel. Both fuel types are needed because gasoline and diesel engines have different strengths. As my automotive engineering students learn, this makes them suitable for different uses. Let’s start with what they have in common. Gas and diesel engines both work through a process called internal combustion. First, they mix fuel with air because the fuel needs oxygen from the air to burn. Next, they compress the fuel-air mixture, which ma...
