Score Cities on Transit Coverage and Frequency

New York has great transit—if you live on the right block. Phoenix has a light rail—but most people never use it. A public transit score tells you how well a city's system works in aggregate, not whether the 6 bus stops near your future apartment. Chicago scores high because the L runs frequently to many neighborhoods. Los Angeles scores lower because coverage is spotty despite recent investments. This tool compares coverage, frequency, and convenience scores between cities so you can see what you're getting into before you commit to car-free life—or accept that you'll need a car anyway.

The difference between a 75 transit score and a 35 transit score is the difference between selling your car and needing two.

Transit Score Breakdown: What's Being Measured

The overall accessibility score combines three components. Each one matters differently depending on how you'd actually use transit.

Component weights

• Frequency (40%) — How often trains/buses come
• Coverage (30%) — How much of the city has stops
• Convenience (30%) — Night service, transfers, overall usability

Frequency gets the most weight because it's what makes transit usable day-to-day. A bus stop on your corner is worthless if the bus comes every 45 minutes. A train that comes every 5 minutes lets you skip checking schedules entirely—you just show up.

80-100: Transit city

New York, San Francisco, Chicago. You can live without a car entirely. Many residents do. Frequent service, extensive coverage, reliable night options.

60-79: Usable transit

Boston, DC, Philadelphia. Transit works for commuting and many errands. You might want a car for suburban trips or late nights, but it's optional for daily life.

40-59: Limited usefulness

Denver, Portland, Seattle. Transit exists and works for specific corridors. But most neighborhoods require a car. You might use transit for downtown trips, not daily life.

Below 40: Car required

Phoenix, Dallas, Houston. Transit is minimal. Some people use it out of necessity, but the system doesn't serve most residents' needs. Plan on owning a car.

Car-Free vs Car-Light Realities

"You don't need a car" and "you can get by without a car" are different statements. Only a handful of US cities truly support car-free living. Many more support car-light—owning a car but using it rarely.

Car-free (score 75+)

You can handle all daily needs without a car: commuting, groceries, doctor visits, evening activities. Transit + walking + occasional rideshare covers everything.

Reality check: Even in NYC, some people want cars for weekend trips, Costco runs, or visiting suburban family. "Can live without" doesn't mean "should."

Car-light (score 50-74)

Transit handles your commute and many errands. But you need a car for some trips: suburban shopping, late-night activities, trips outside the transit network.

This is where most "transit-friendly" US cities actually land. You might drive 3-4 times per week instead of daily.

The financial calculation

Car ownership costs $500-$1,000/month (payment, insurance, gas, maintenance, parking). In car-free cities, paying $300 more rent for a transit-accessible apartment often saves money overall. In car-light cities, you might pay transit premium rent AND still own a car—worst of both worlds. Run the total cost, not just rent.

When comparing cities, think about what you'd actually give up. Some people happily trade car access for walkable neighborhoods. Others find car-free life isolating when friends live in suburbs.

Rush Hour Service vs All-Day Coverage

Many transit systems perform well from 7-9am and 5-7pm, then collapse. If you work standard office hours, rush-hour service matters most. If you work evenings, weekends, or need flexibility, all-day coverage matters more.

9-to-5 commuters

You get the best service cities offer. Trains every 5-10 minutes, express buses, full coverage. Your experience will match or exceed the transit score. After work, service degrades but you're already home.

Service industry and shift workers

If your shift ends at 11pm or starts at 5am, check late-night and early-morning service specifically. Many cities run "owl" service on limited routes only. The transit score assumes average usage patterns—yours might differ significantly.

Weekend users

Saturday service is often 50-70% of weekday frequency. Sunday is worse. If your social life happens on weekends, weekday commute quality is irrelevant. Check weekend schedules separately.

Parents with school pickup

School pickup is 3pm. Rush hour service hasn't started. Mid-afternoon frequency can be half of peak. If you're counting on transit for school runs, verify specific route schedules.

The convenience score tries to capture all-day usability, but it's an average. If your schedule is non-standard, research specific routes for your actual commute times.

The Last-Mile Problem (Suburbs, Exurbs, Edge Cities)

City-wide transit scores average together the urban core (usually good) and outer areas (usually bad). If you're considering suburban neighborhoods, the citywide score is misleading. Your specific location matters enormously.

Same city, different realities

Chicago Loop: Effective transit score ~95. Multiple L lines, frequent buses, walk to anything.

Chicago suburbs (Naperville): Effective transit score ~25. Metra train to downtown only. Car required for local trips.

Chicago citywide average: ~75. Neither reality for most residents.

Near a rail station

Living within 10-minute walk of a rail station usually means transit works for your commute. The rest of suburban life still requires a car, but your daily commute is covered.

Bus-only suburbs

Suburban buses run infrequently (30-60 minutes) and connect to transit hubs, not your final destination. Multiple transfers for most trips. Technically "transit accessible" but practically car-dependent.

No fixed-route service

Many exurbs and edge cities have no regular transit at all. Park-and-ride lots assume you drive to transit. The citywide score includes these areas, pulling down the average.

After using this tool for city comparison, research your specific neighborhood using Walk Score's Transit Score or Google Maps transit routing. The address-level reality can differ 40+ points from the city average.

Transit Score vs Actual Commute Time

A high transit score doesn't guarantee a short commute. It means transit exists and runs frequently—your specific route might still take forever.

1. Score measures access, not speed. A city with frequent buses everywhere might have a higher score than one with fast trains on limited routes. But the train city might give you a faster commute if your route is covered.
2. Transfers kill commute time. A 15-minute train ride with a 10-minute wait for a connecting bus is 25+ minutes each way. Two transfers can double apparent commute time. Check your specific route.
3. Last-mile walking adds up. "5-minute walk to the station" plus "10-minute walk from downtown station to office" is 30 minutes of walking daily. Fine if you like it, exhausting if you don't.
4. Compare to driving time. A 45-minute transit commute might still beat a 35-minute driving commute when you factor in parking stress, gas costs, and productive time reading on the train.

The score confirms a city has a working system. It says nothing about whether your specific trip works. So before you sign anywhere, drop your future workplace into Google Maps, set it to transit, and run it at the hours you'd actually travel. If that route holds up at 8am and again at 11pm, the number earned your trust. If it doesn't, the citywide average was hiding your reality.

How This Score Fits With Everything Else

You'll notice this score doesn't always match Walk Score's Transit Score, and that's fine. The two use different data, different weighting, and different methods. Walk Score looks at a specific address; this tool compares whole cities. Both are approximations, so the smart move is to use them together, city-level here and address-level over there once you've narrowed the list.

A higher score usually does translate into cheaper transportation. Better transit tracks with lower car dependency, and a household that drops from two cars to one, or from one to none, saves somewhere around $500 to $1,000 a month. Fares aren't free either, mind you. Monthly passes in the big systems run $75 to $130. Whether the trade nets out in your favor depends on your own numbers.

Keep in mind what the score leaves out. It counts fixed-route transit, so buses, trains, and light rail. Bike-share and e-scooters aren't in it, but they quietly solve the last-mile problem in a lot of places, which can make a middling 55 feel car-optional if you're happy on a bike. Planned expansions aren't in it either. The numbers reflect what runs today, not the rail lines LA and Austin are building. Those might lift scores in five to ten years, though transit projects slip and shrink often enough that you shouldn't bank on them.

Safety sits outside the score too. Accessibility and personal security are different questions, and how safe a system feels varies by city, by line, and by hour. Dig into local news and rider forums for the current picture before you rely on a route at night. As for the numbers themselves, they come from the Federal Transit Administration's National Transit Database, American Public Transportation Association ridership data, and the transit agencies' own published schedules, all public data compiled here for comparison.
