Abstract
A method and apparatus for determining a reachable area based on a road network are provided. The method comprises: acquiring a current location of a user and a road network map; generating a road node map based on the road network map; searching on the road node map for a boundary point extending for a maximum travel distance starting from the current location of the user along a road; and determining a reachable area based on the searched boundary point.
