The Helsinki Region Travel Time Matrix can now be observed via an interactive web map http://www.mapple.fi !
The interface allows you to inspect travel times in different modes of transport (public transport, car and walking) at different times of the day (rush-hour, noon) to and from locations of your own choise within the Helsinki Region.
The application was developed by Joona Repo, Rami Piiroinen and Henrikki Tenkanen, good job guys!
