A radius is created when drawing a straight line from a central point to all possible points in a circle. It’s useful for searching where’s nearby, assuming it’s possible to travel as the crow flies.
Creating a distance radius map
The tool lets you draw circles around a point on a Leaflet map. Adjust the size of the circle using the mileage drop down box and select your location by typing in the box.
Drawing a travel time radius
If you want to see where’s reachable ‘within X minutes’ by car or public transport you can also use this tool. Once you’ve made a distance radius just click the public transport button. We calculate the travel time map area based on our TravelTime API. Learn more about the API here. You can then use the drop down to adjust the number of minutes spent travelling or click ‘view reachable by driving’ to see a drive time area. The area calculated assumes the person sets off at 9am and can travel from the starting point to the end point using real routes, not in a straight line. This is rarely a perfect circle.
Explore Travel Time Areas
To adjust the departure time or add more than 1 area on the same map try our TravelTime Maps tool. You can search for points of interest within the area or find overlapping areas between 2 start points and more.
