Abstract
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 reachable from a given address or location within a specified travel time utilizing a specified mode of transport (e.g. driving, biking, walking, public transportation, etc.). Techniques are disclosed for enabling rapid calculations of travel times. In one embodiment, rapid generation of travel times and associated travel sheds may be enabled by performing pre-processing steps (e.g. downsampling, progressive road type removal, etc.) on road graph data. The pre-processing steps reduce the road graph while still preserving enough 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.
