INTERAGENCY NETWORK DATA INTEGRATION USING MILEPOST STATIC SEGMENTATION

To fulfill the Genesee Transportation Council's (GTC) mission, the Central Staff must be able to integrate its member agencies' roadway network databases in a common framework to perform analyses transparent to jurisdiction. Geographic Information System (GIS) is being used as the tool of integration to accomplish this. It works with these member agencies to modify their databases to allow them to be imported into GTC's Regional GIS Network Database (RGND), which is being constructed with the member agencies' route identification and milepoint references. In order for GTC's regional GIS network database to meet all of the database integration and analysis needs, a "GTC milepoint static segmentation" linear referencing scheme was devised. This methodology is a compromise between strict static segmentation and pure dynamic segmentation. The methodology is patterned after address matching routines. GTC's Regional GIS Network Database will allow Central Staff to perform GIS queries and analyses across the entire federal-aid eligible roadway network regardless of jurisdiction. In addition, data sharing between agencies will be greatly enhanced as the Regional GIS Network Database will also act as a common translator for data sharing between GTC member agencies. This paper includes a step-by-step description of this project, the various procedures and techniques used, as well as the lessons learned in accomplishing the goals of the project.
