iGeolise make maps searchable by time rather than distance. Users of the data can identify the best possible locations within 15 minutes drive rather than 5 miles radius. They understand that not all locations within a miles-based radius will be accessible for the average person because congestion, infrastructure and other factors can impact accessibility. Using travel time data increases the accuracy of location-based decision making. 

They offer a consumer-website facing search TravelTime platform and a GIS analysis feature. For more information click here
