Walk Score vs. Transit Score: What They Measure and What They Miss

Walk Score and Transit Score sound alike, but they measure very different things. Here is what each number means, where it fails, and how to use them when picking a city.

Updated November 6, 2026 · Based on 10 sources · How we research

Walk Score and Transit Score both run from 0 to 100, both come from the same Redfin-owned company, and both get quoted next to each other in city profiles as if they answer the same question. They do not. Walk Score counts how many useful destinations sit within walking distance of a specific address. Transit Score counts how much bus, rail, and ferry service is nearby. One can be high while the other is low in the same place, and treating them as interchangeable is how people end up in a 'Walker's Paradise' neighborhood with no realistic way to leave it without a car. This guide explains what each score is actually built from, what it refuses to look at (safety, terrain, weather, sidewalk quality), and how to read the city-wide averages that appear on rankings like our best cities to live in 2026.

What a Walk Score of 89 actually means

Walk Score is Redfin's patented 0 to 100 measure of how many useful destinations sit within walking distance of a point on a map. The company groups amenities into categories such as grocery stores, restaurants, shopping, coffee shops, banks, parks, schools, bookstores or libraries, and entertainment, then uses a distance-decay function. According to the Walk Score methodology page, amenities within a five minute walk (about 0.25 miles) get maximum points, points fall off as distance grows, and anything more than a 30 minute walk counts for nothing. The raw amenity score is then adjusted for pedestrian friendliness using intersection density, block length, and population density.

The published bands are specific: 90 to 100 is a 'Walker's Paradise' where daily errands do not require a car, 70 to 89 is 'Very Walkable' where most errands can be done on foot, 50 to 69 is 'Somewhat Walkable', and anything under 50 is labeled car dependent. So when Copenhagen appears in our ranking with a city-wide Walk Score of 89, the claim is narrow and specific: for the average resident, most everyday errands are reachable on foot. It is not a claim that walking there is safe, pleasant, flat, or dry.

The distance decay inside the formula also matters when you compare scores. Each category uses diminishing returns, so the first supermarket counts far more than the twentieth, and amenities past the quarter-mile ring contribute less and less. That is why dense city centers all converge on similar high scores: once you cross the threshold where a grocery store, a couple of restaurants, a park, and a school all sit inside a short walk, piling on more cafés barely moves the number.

Transit Score is a service quality measure, not a distance measure

Transit Score looks different under the hood. The Transit Score methodology assigns each nearby route a 'usefulness' value from three ingredients: service frequency, mode weighting (heavy or light rail counts 2x, ferry and cable car 1.5x, bus 1x), and a distance penalty for how far the nearest stop is. The usefulness values are summed, then normalized on a logarithmic scale against a benchmark built from the centers of San Francisco, Chicago, Boston, Portland, and Washington, D.C.

The practical consequence is that a city with dense bus coverage but infrequent service will score lower than one with a smaller network of frequent rail lines. Zurich, which scores 95 for transit in our ranking, benefits from frequent trams and S-Bahn trains that run on predictable intervals. Singapore, at 92, leans on its MRT metro network. Bus-only service, even extensive bus service, has to run very frequently to reach comparable numbers because it is weighted at 1x.

The bands mirror Walk Score: 90 to 100 is 'Rider's Paradise', 70 to 89 is 'Excellent Transit', 50 to 69 is 'Good Transit', 25 to 49 is 'Some Transit', and below 25 is 'Minimal Transit'. Redfin's own write-up explains that city-level scores are computed block-by-block and then population weighted, so the number reflects what a typical resident experiences, not what a map of lines looks like.

Why a city can have a high Walk Score and a low Transit Score

This is where the two scores pull apart, and where readers get into trouble treating them as the same metric. Walk Score rewards the presence of amenities within a short radius. Transit Score rewards the presence of frequent transit service. A compact medieval town can have everything you need inside half a mile and almost no public transit at all, because it does not need any. Bruges is the clearest example in our data: Walk Score 95, Transit Score 72. The historic center is a car-free zone compact enough that walking from any car park to any hotel takes 10 to 15 minutes. The transit score is lower not because the city fails residents, but because the city is small enough that extensive rail and bus service would be redundant.

The reverse happens too. Medellín, Colombia carries a Walk Score of 72 and a Transit Score of 88 in our ranking. The Medellín Metro and the Metrocable aerial tram system reach neighborhoods on steep hillsides that are not realistically walkable even if the amenities are close by on a map. A pedestrian trying to walk half a mile up a 20% grade is in a different situation from one strolling along a flat Danish boulevard, and Walk Score does not know the difference.

The mismatch shows up in American cities in a different form. Madison, Wisconsin has a Walk Score of 72 and a Transit Score of 45. The isthmus around the University of Wisconsin is walkable, but the bus network, while present, does not have the frequency to earn a higher transit number. Nashville, Tennessee is more extreme: 58 Walk Score, 35 Transit Score. Downtown Nashville is walkable in short bursts and the rest of the metro is built for cars. A reader who sees Nashville on a 'walkable cities' list and assumes transit will follow is going to be disappointed.

City	Walk Score	Transit Score	What the gap says
Bruges	95	72	Tiny, car-free medieval core; transit not needed
Zurich	88	95	Dense amenities plus world-class rail and tram
Copenhagen	89	85	Walkable, but residents mostly cycle, not ride
Singapore	82	92	MRT metro outpaces walkable amenity density
Medellín	72	88	Steep terrain; metro and cable cars do the work
Madison, WI	72	45	Walkable isthmus, weak bus frequency
Nashville	58	35	Pockets of walkability, car-dependent overall
Cary, NC	45	35	Suburb; both scores low, as the form predicts

What Walk Score refuses to look at

The hardest part of using Walk Score honestly is knowing its blind spots. It does not look at crime or perceived safety, which the City Health Dashboard flags as a significant barrier to physical activity that is not incorporated in Walk Score ratings. It does not account for topography; a flat 0.5 mile and a 0.5 mile up a 15% grade are identical to the algorithm. It ignores weather, so a city with four months of ice and a city with Mediterranean sun look the same if the amenity density matches. Wikipedia's Walk Score entry summarizes the gaps bluntly: no sidewalks data, no traffic lane crossings, no crime, no weather, and no distinction between a full supermarket and a convenience store selling chips and liquor.

This matters because two cities can look identical on paper and feel entirely different on foot. Our ranking shows Copenhagen at Walk Score 89 and the medieval center of Bruges at 95. Both deliver on their numbers, but Copenhagen's residents overwhelmingly choose bikes over walking: Wikipedia reports that 62% of Copenhageners commute by bicycle to work, school, or university each day, and that is a thing Walk Score cannot see. A separate Bike Score exists for exactly this reason, and it tells a very different story from either walking or transit.

The amenity-quality blind spot is often the practical one. Walk Score counts a dollar store and a Whole Foods as 'a grocery store'. It counts a chain coffee shop and a neighborhood roaster the same. In Kyoto, a Walk Score of 78 covers a mix of neighborhood grocers, convenience stores, and traditional markets that behave very differently from a US supermarket, so a resident's day-to-day errands do not necessarily map to what an American reader imagines when they see the number.

How city-wide averages are actually built

Walk Score and Transit Score were designed to score individual addresses. According to Redfin's write-up, city-level numbers are computed by running the algorithm block-by-block and then population weighting the results. City Observatory explains why that matters: a simple average over land area would be dominated by low-density outskirts and industrial zones where almost nobody lives, producing a number that does not describe the typical resident's experience. Population weighting flips that, so the score reflects what the median person sees when they step outside their front door.

The practical effect is that city-wide scores skew toward the densest, most populated neighborhoods. A city like Charlotte, North Carolina scores a Walk Score of 68 largely because its uptown core and inner neighborhoods are walkable even though vast swaths of the metro are not. The number is honest for an inner-city renter and misleading for a suburban homeowner 15 minutes away. Cary, North Carolina, a planned suburb inside the same Research Triangle, lands at Walk Score 45 and Transit Score 35, because the population is more evenly distributed across a car-oriented layout.

That also means city rankings compress a lot of variance. Our top three cities for quality of life, Singapore, Zurich, and Copenhagen, all score above 80 on both walk and transit, but the neighborhood you pick inside each will swing the real-world number by 20 or 30 points. Readers using city averages to decide where to live should treat them as a starting filter, not as the answer.

Does a high Walk Score mean you can skip the car?

Only in combination with a high Transit Score, and even then only in certain city sizes. 'Daily errands do not require a car' is Walk Score's own definition for the 90 to 100 band, but 'daily errands' is a narrower category than 'everything you need a car for'. A visit to a doctor on the other side of the city, a trip to see family in a nearby town, a Costco run, a trip to the airport, and a weekend outside town are not daily errands, and Walk Score does not address any of them. That gap is what Transit Score fills: if transit is weak, those trips default back to a car even when your morning coffee and groceries are a block away.

Zurich and Singapore are examples of true car-optional cities in our ranking. Zurich pairs Walk Score 88 with Transit Score 95 and has the SBB intercity rail network for travel outside the city. Singapore is a city-state, so almost every trip that matters is inside the transit network's reach. These are the cases where high scores on both metrics mean a resident genuinely does not need to own a car.

The mid-cases are harder. Melbourne scores 78 walk and 85 transit, which supports a car-free life inside the inner tram zones but less so farther out. Valencia hits 85 walk and 78 transit and works as a car-free base for most residents, with Spain's national rail filling in longer trips. The pattern is consistent: either both numbers need to be high, or the gap between them has to be filled by something the scores do not track, like Copenhagen's cycling network or Medellín's cable cars.

How to read these scores when picking a city

Treat the two numbers as a pair, not a single metric. A city with Walk Score above 80 and Transit Score above 80 is a plausible car-free city for the average resident. A city with a high walk score and a weak transit score is pleasant on foot in its best neighborhoods and car dependent for anything farther. A city with the reverse, lower walk but strong transit, usually has a dense transit spine serving less dense neighborhoods, which works if you live near a station and struggles if you do not.

Then look at the gaps the scores do not show. If you are moving for a job, check topography on a map. If you are moving with kids or elderly parents, check sidewalk quality and crosswalk design, which only a site visit or street view will reveal. If you are moving somewhere cold, check winter walking conditions; a 95 Walk Score in a city with four months of unshoveled ice means something different from a 95 in Valencia. And if you care about safety on foot after dark, the walkability score tells you nothing and crime data has to be read separately.

Finally, drop from the city average to the neighborhood number before making any decision. Our ranking uses a city-wide population-weighted figure because it is comparable across cities, but the Walk Score and Transit Score sites both expose address-level numbers. The score for a single apartment is the number you will actually live with.

The short version

Walk Score answers one specific question: are useful destinations close enough to walk to. Transit Score answers a different one: does public transit serve this place well enough to use it. Both numbers are useful, both are built with defensible methodology, and both leave out safety, terrain, weather, and amenity quality by design. The cities in our ranking that pair high walk scores with high transit scores, Zurich, Singapore, Copenhagen, are the ones where the numbers actually describe a car-optional life. For the rest, treat the scores as a filter and then do the second-pass work the algorithm cannot do for you.

Questions people ask

What does a walkability score of 89 mean for a city?+

A city-wide Walk Score of 89 sits at the top of the '70 to 89 Very Walkable' band, which Walk Score defines as 'most errands can be accomplished on foot'. It is a population-weighted average of block-by-block scores, so it describes the typical resident's neighborhood, not every address in the city. The number is a claim about distance to amenities, not about safety, terrain, or sidewalk quality.

What is the difference between Walk Score and Transit Score?+

Walk Score measures how many useful destinations sit within walking distance of an address, using a distance-decay function that maxes out at a 5 minute walk and drops to zero after a 30 minute walk, across categories like grocery, restaurants, parks, and schools. Transit Score measures how well public transit serves the location, based on route frequency, transit mode (rail counts 2x, bus 1x), and distance to the nearest stop. One rewards amenity density, the other rewards transit service, and they can diverge sharply in the same city.

Does a high walkability score mean I won't need a car?+

Not by itself. Walk Score's 90-plus band is defined as 'daily errands do not require a car', but longer trips to doctors, airports, family, or stores outside the amenity radius still typically need transit or a car. A genuinely car-optional city usually needs both a high Walk Score and a high Transit Score, like Zurich (88/95) or Singapore (82/92) in our ranking.

Why can a city have high walkability but low transit score?+

Small, dense cities often have everything within walking distance and little reason to build extensive transit. Bruges in our ranking is the clearest example: Walk Score 95 because the medieval center is a compact car-free zone, Transit Score 72 because the city is too small to need frequent rail or bus service. Conversely, a hilly city like Medellín scores lower on walk and higher on transit because the Metrocable does what walking cannot.

Does walkability score account for safety, terrain, or weather?+

No. Walk Score explicitly excludes crime, topography, climate, sidewalk quality, and traffic crossings. It also does not distinguish amenity quality, so a convenience store and a full supermarket count as the same 'grocery store'. These omissions are the main reason two cities with identical scores can feel entirely different on foot, and why the score is best used as a filter rather than a final answer.

How is a city-wide walkability average calculated?+

Walk Score runs its algorithm block-by-block across the city, then averages the results weighted by population. Low-density industrial zones and bodies of water contribute little or nothing because few people live there. The result is a number that approximates what the typical resident experiences rather than an average across all land area.

Why do Walk Score and Transit Score both run from 0 to 100?+

They share the 0 to 100 scale and five-band labeling by design, so address pages can show them next to each other. Both scales are normalized against benchmark cities, San Francisco, Chicago, Boston, Portland, and Washington, D.C. for Transit Score. The shared format makes them easy to compare, but it also encourages the mistake of treating them as measuring the same thing.

Are there newer walkability indexes that fix these gaps?+

Yes. Academic efforts, including a European walkability index published in 2025, add topography, street network quality, and in some cases perceived safety to the amenity-density approach. The City Health Dashboard and various research indexes also incorporate sidewalk data and land use mix. Walk Score remains the most widely cited because it covers the US, Canada, and Australia at address level, but it is not the only option.
