Many departments of transportation are in the process of creating or maintaining a linear referencing system for local roads. Due to the amount of features associated with a local road network, this process is expensive and time consuming. A technique that employs passively-collected, non-differentially corrected Global Positioning System (GPS) data to create and populate link and node information in a linear referencing system is presented. Starting with freely-available Topologically Integrated Geographic Encoding and Referencing (TIGER) data maintained by the U.S. Census Bureau, mined GPS data is used to generate link features, link lengths, link attributes, node locations, and even traffic control devices at intersections. The results indicate that TIGER lines are a valid starting point for the creation of a local road linear referencing system and that non-differentially corrected GPS data can be used to validate, populate, and maintain such a system.
