ABSTRACT
The paper presents the time accessibility analysis of the second line of Warsaw subway, which is still under construction. To designate time accessibility anywhere in the city the Inverse Distance Weighted interpolation method was used. In the previous authors research this method was considered the most appropriate interpolation of such kind of data. The estimated travel time is presented in the form of isochron map, which shows how long it takes to travel between a particular place and the nearest subway station, using public transport. For more than 50% of Warsaw territory this travel time does not exceed 30 minutes with the mean absolute error not greater than 2 minutes.

Keywords: accessibility map, travel time map, IDW method, isochrones, public transport
