Isochrone Map — Travel Time Visualizer
An isochrone map shows every area you can reach from a starting point
within a given travel time. This tool draws that reachable zone as a
shaded polygon on an interactive map, using real road and path networks
for driving, cycling, and walking.
What is an isochrone?
An isochrone (from Greek iso, equal, and chronos,
time) is a line or region connecting points that can be reached in the
same amount of time. On a map, isochrones help answer the question:
“How far can I get in 30 minutes?” Unlike a simple radius
circle, isochrones follow actual streets, bike lanes, and footpaths, so
the shape reflects real-world accessibility.
Use cases
-
Commute planning — Compare neighborhoods by how much
of the city you can reach within your acceptable commute window.
-
Real estate — Evaluate properties by reachable
amenities, schools, transit, and job centers within a set travel time.
-
Logistics and delivery — Estimate service areas for
drivers and couriers based on realistic drive times rather than
straight-line distance.
-
Urban planning — Visualize 15-minute city concepts
and pedestrian or cycling accessibility from key hubs.
How to use this tool
Enter a starting location in the search box and select your travel mode
(driving, cycling, or walking). Set your desired time limit using the
hours and minutes controls, then click Go. The map will geocode your
location, fetch an isochrone from the Mapbox Isochrone API, and display
the reachable area as an amber shaded polygon with an outline. A
marker shows your origin, and statistics display the place name, mode,
total time, and approximate area in square kilometers.
