A system and method are provided for generating travel sheds which show the area reachable in a given amount of time by different modes of transport. A travel shed may consist of a series of polygons or other geometric shapes showing areas which are reachable from a given address or location within a specified travel time by utilizing a specified mode of transport (e.g. driving, biking, walking, public transportation, etc.). Techniques are disclosed for enabling the rapid calculations of travel times. In one embodiment, the rapid generation of travel times and associated travel sheds may be enabled by performing a number of pre-processing steps (e.g. downsampling, progressive road type removal, etc.) on road graph data. The pre-processing steps reduce the size of the road graph while still preserving enough of the road graph to generate accurate travel sheds. One example use of travel sheds is to enable searching for points of interest (e.g. homes, apartments, hotels, restaurants, schools, parks, etc.) according to specified travel times.
