Travel Time Map

Travel Time Map is a relatively simple application that enables you to generate isolines to indicate the maximum distance that can be traveled in a specified period, as well as view which points on a map are placed at the same distance away from a particular point when traveling by road.
The program relies on the Iso4App API and serves as a demo for the service’s capabilities.

Test the Iso4App API from your desktop

First and foremost, you should know that Travel Time Map requires a valid API key before any data can be processed. This key can be requested on the developer’s website, and it comes with several usage limitations.
Each operation requires a certain number of credits, and you can check how many you have left by logging into your newly created account. Of course, you can upgrade your API key to gain more credits.

Generate isodistance and isochrone polygons

Travel Time Map gives you an idea of how much distance can be covered in a specified amount of time from a user-defined starting point. You can provide the travel time, method of transportation and speed limit, as well have the application reduce queue times and ignore tolls.
Moreover, the program is capable of depicting areas that are situated an equal distance away from a given point. This function is very useful in urban environments, as it shows which areas are easily reachable by road.

Powerful service that supports numerous countries and map tiles

While the Iso4App API does not cover the entire globe, areas such as Europe, North America, Central America, China and Australia-Oceania have already been implemented.
Furthermore, you can choose from multiple map tiles when generating isolines, including OpenStreetMap, CartoDB, MapQuest and OpenTopoMap.
All in all, Travel Time Map is an interesting application for those who wish to test out the Iso4App API, which can calculate maximum travel distances and travel times, as well as represent this data in the form of polygons using various map tiles.
