Claim:
1. A system for selecting a path according to a plurality of selection conditions, comprising: a plurality type of driving data recorder (DDR) databases, each storing a plurality of paths from each of a plurality of path nodes to another of the plurality of path nodes and a set of vehicle traveling history data for the plurality of paths, the set of vehicle traveling history data corresponding to one of the plurality of selection conditions; a receiving module, receiving an initial path node, an end path node, and a set of type ratios, the set of type ratios having a plurality of ratios each corresponding to one of the plurality type of DDR databases; a querying module, querying the set of vehicle traveling history data according to the initial path node to the end path node and the plurality of paths corresponding thereto from each of the plurality type of DDR databases; a calculating module, calculating the set of vehicle traveling history data for each of the plurality of paths stored in each of the plurality type of DDR databases to obtain a calculation result, respectively, and providing a type calculation data for each of the plurality of paths according to the calculation result, respectively; and a path providing module, normalizing the set of type ratios and the type calculation data of the plurality of paths corresponding to each of the plurality type of DDR databases, respectively, calculating an average mix rank for each of the plurality of paths by giving a weight to normalized the type calculation data, and sorting the plurality of paths according to the average mix rank, so that a user is able to select path.
