Abstract
 Integrating Applications and Databases with NCDOT Linear Referencing System Track: Transportation Author(s): Jun Wu, John Farley, Ray Chilcote The NCDOT Linear Referencing System (LRS) released in the August of 2006 provides a framework to integrate fragmented applications and databases. It consists of a collection of databases and application systems, serving as a central repository of the North Carolina state-maintained transportation network with topology and geometry. Integration with the LRS will enable easier manual and automated solutions for referencing a wide variety of roadway attributes to the transportation network. These solutions would update or refresh the location reference information in departmental database systems and therefore greatly improve the data quality, data consistency, and lower the maintenance costs. This article will discuss the Location Referencing Methods supported by NCDOT LRS version 1.0 and derive integration options. A few case studies will also be presented.
