Abstract
A method, apparatus and computer program products are provided for collecting and analyzing route to determine the routes of a transit system. One example method includes receiving GPS data from a plurality of buses or uses from along a transit roué, the discreet GPS reports organized into a set, generating a plurality of clusters, each cluster is comprised of a first GPS point from a first set and one or more subsequent GPS points, each subsequent GPS point from a different set, and wherein each subsequent GPS point is located within a predetermined distance of the first GPS point. The clusters are then connected to form a route polylines. Outliers, inaccuracies, and/or route endpoints may be pruned to improve accuracy and efficiency of the method. The method may also order the aggregated clusters using spatial and temporal data of the GPS reports to improve accuracy.
