Visualizing urban accessibility as continuous areas instead of transit lines (isochrone map)

Visualizing urban accessibility as continuous areas instead of transit lines (isochrone map)

I’ve been experimenting with a different way of looking at public transport accessibility in cities.

Instead of focusing on routes, stops, or network diagrams, this approach shows how far you can actually get within a given travel time - visualized as continuous areas that merge together (similar to isochrones, but simplified for readability).

The idea is to shift the perspective from “what lines are available here?” to “what parts of the city are effectively within reach?”

It also starts to highlight differences between areas that look well-served on a map, but feel very different in terms of actual access.

Curious how this resonates from an urban design perspective -
do you think this kind of visualization is useful when thinking about accessibility, land use, or planning decisions?

Barcelona, Spain - Visualizing transit accessibility as continuous areas instead of routes

I’ve been experimenting with a different way of visualizing public transport accessibility in Barcelona.

Instead of showing routes or lines, this diagram shows how far you can actually get within a given time using transit - with areas merging into continuous shapes (similar to isochrones, but designed more for clarity and comparison).

The idea is to make accessibility easy to grasp at a glance, rather than focusing on specific routes or schedules.

Curious what people here think - does this kind of visualization feel intuitive or useful?

Do you find location descriptions in Airbnb listings actually helpful? [Bulgaria]

When I’m booking an Airbnb, I often feel like it’s hard to judge how good the location really is.

Listings usually say things like “close to downtown” or “15 minutes to the center,” but that can mean very different things depending on traffic, public transport, transfers, etc.

So I started thinking - wouldn’t it be more useful to see something like a travel-time map?
For example, a simple visual showing how far you can actually get within, say, 20–30 minutes using public transport.

Not routes or directions, just a clear sense of how connected the place is.

I’m curious how others feel about this: Would something like that actually help you choose a place? Or do you rely on other signals (reviews, neighborhoods, etc.) instead?

Would love to hear how you usually judge location when booking.

Would a travel-time isochrone map help guests better understand an Airbnb location?

I host an Airbnb, and one thing I’ve always struggled with is how to clearly show guests how “well-located” the place actually is.

Saying things like “15 min to the city center” or “good public transport” often feels vague and sometimes even misleading, depending on time of day, transfers, etc.

So I started experimenting with a different approach - creating travel-time maps that show how far you can realistically get within a given time using public transport (instead of listing routes or lines).

The goal is to make the location more tangible and easier to compare across listings.

Before I go further with this, I wanted to ask: Do you think something like this would actually be useful in a listing? Would it help guests make decisions, or is it overkill?

Curious to hear your thoughts or any ideas.

Would a map like this be useful for understanding public transport accessibility?

I built this travel-time map for Rome using public transport data (OSM + GTFS), where colors show how far you can get within different time ranges.

The idea isn’t routing, but more about visualizing accessibility - e.g., “where can I get within ~30, 45, 60 minutes?”

I’m curious what people here think:

  • Would something like this actually be useful in practice?
  • Are there important factors you feel are missing in this kind of visualization?
  • Does OSM data quality noticeably affect results in your experience?

Interested in feedback from people working with OSM, routing, or transit data.
