How to use the How Far Can I Travel Tool

You do not need to interact with the map as it will move and resize depending on what you input. To start with, input an address / location in to option 1. Remember, the entire world has to be searched to find this location so make it precise. For example "123 Example Road, ExCity, Excountry" is a good method.

Next you need to indicate the total road distance you can travel. This can be done in two ways:

2A : By inputting a speed of travel and a travel time. For example you may wish to walk for 60 mins.

2B : By inputting a distance. For example you wish to find somewhere 50km away.

Optional, Specify how accurate you want the results to be. Accuracy can be low medium or high. This will result in the tool running faster or slower (more accurate means more time needed). If you find your web browser becoming slow of even crashing you are advised to lessen the accuracy.

Then click [Search] and wait a short time for the start point and all points on the perimeter of your range to be displayed.

Hover over a perimeter marker to see it's road distance from the start point and the as the crow flies distance. Click on a marker to see the address of any nearby locations.

You can then export the area to KML file with or without endpoints. Endpoints are the yellow pins that appear inside Google Earth

About

The How Far Can I Travel tool has been developed after requests by numerous people all of whom had different applications for it but all asked for a similar thing. "Instead of a radius as the crow flies, can you do a radius as the car drives" was the most popular way of explaining this. Please get in contact to report bugs or suggest improvements.
