How travel time maps work
What is a travel time map?
A travel time map shows everywhere you can reach from a starting point within a set time — by car, public transport, bike or on foot. It maps the area the road network and transport infrastructure puts within reach, not a straight-line distance radius. The shape it draws is called an isochrone.
That makes it different from a distance radius. A radius answers "what's within ten miles, as the crow flies?" A travel time map answers what people mean: "where can I actually get to from here?"
Drive time maps & driving radius maps
A drive time map is a travel time map set to driving: the area a car can cover in the time you set, following real roads at real speeds at the given departure or arrival time. That's what a driving radius map — or a drive time radius map — is for. Where a plain radius circle only answers "how far away is that?", a driving time distance map shows the same reach in time rather than miles or kilometres.
In this free map generator tool, you can add up to three starting points to see where the areas overlap — answering the questions behind a meet-up, a delivery round, or a new site. With a TravelTime Isochrone paid license, you can add thousands of origins for larger-scale, high-performance analysis.
Commute time maps
A commute time map shows everywhere within a commute you'd accept. Pick a starting point — home or work — set how long you're happy to travel, and the shaded area is everything in reach. Use the commute map to find a home near a job, a job near home, or see how easily you can reach other key places from your workplace. Switch between public transport, driving, cycling and walking to see how much the reach changes with how you travel.
Every place in the list beside the map carries its own travel time, so a commute time map doubles as a shortlist for choosing locations, rather than just a polygon shape.
How the travel times are calculated
Every travel time on the map comes from the TravelTime API, which models the road network, public-transport timetables and walking connections.
The time map is drawn as polygon or isochrones, H3 cells, and geohash, each displaying a travel time boundary — and in the case of H3 and geohash, journey times within the boundary too. The app calls the API and instantly calculates an accurate journey time.
The same TravelTime infrastructure powers bigger commercial jobs too, including retail catchment analysis, site selection and delivery planning. Discover the demos or sign up for a TravelTime account to get started on your own project.
To draw a radius circle instead, or to measure one journey between two places, use the radius map and the distance calculator.
Frequently asked questions
How do I make a travel time map?
Search or drop a starting point, choose a mode (car, transit, walk, cycle) and set the time with the slider. The reachable area redraws instantly as you move it.
What's the difference between a travel time map and a drive time map?
A drive time map is a travel time map set to driving. Switch the mode and the same map shows public transport, walking or cycling instead.
How far can I drive in 30 minutes?
It depends on the roads — motorways stretch the area, city traffic shrinks it. Set the map to driving and 30 minutes to see the real shape from any point.
What is an isochrone?
An isochrone is the line on a travel time map joining every place reachable in the same time. Everything inside the polygon boundary is within reach.
Is a travel time map the same as a radius map?
No. A radius map draws a circle by distance; a travel time map draws the real area you can reach in a time, which is rarely a circle.
Can I map more than one starting point?
Yes. Add up to three and see where their reachable areas overlap. For more starting points, get access to a TravelTime API key.
People also call it a "time travel map" or "travel time calculator". Is it the same thing?
Yes. A time travel map and a travel time calculator are other names for mapping how far you can get in a given time.
