OALLEY is a map that shows you how far you can travel for a given time or a chosen distance.

Depending on the means of transport chosen, OALLEY takes into account several criteria (speed limit on each type of road (city, countryside, motorway), timetables for public transport, cycle paths, etc.) and draws the limit area that you can reach for the specified distance or travel time.

Travel time maps are also called isochrones.
