Using LRS Change Transactions Generated Externally to Maintain Data Integrity in the Pavement Management System in North Carolina

Traditionally the location of pavement management condition data has been referenced in pavement management systems (PMS) using a linear referencing system (LRS). Unfortunately the LRS is never completely static and any particular point’s route/milepoint reference is apt to change over time as route names are changed or roads are realigned. As a result of this, the start and end references for typical pavement management data need to be updated continuously as the network changes. The paper will cover the LRS updating method being implemented in North Carolina. Since the ‘system of record’ for official changes to the route/milepoint linear referencing is the Road Inventory Section under the Geographic Information System (GIS) Unit, these changes are recorded and passed through an interface to the PMS. The PMS then breaks these transactions down and applies them throughout the PMS database to keep all data accurate over time. The implementation has shown that the approach of allowing existing centralized processes for the maintenance of a single statewide LRS to remain, but have all change transactions recorded and made available to multiple external systems, is a good one. The approach allows for integrating multiple external systems dependent on various linear referencing methods.
