2 Outline Scope of Work Architectural Goals Architecture Scalability Functionality Examples

3 Mn/DOT Scope of Work Mn/DOT Scope of Work Replace portions of TIS with LDM Replace data maintenance Maintain static segments Pavement Condition Rating, Traffic Safety Sections, Traffic Volume Segments Crash Locations Maintain control sections Maintain roadway characteristics Maintain intersections and interchanges Maintain traffic count locations Propagate changes to the linear datum Reports

4 Pavement P274 Domain Railroad Bridge ArcGIS based Reporting Application Reports Traffic Safety Road Characteristics Location Data Manager ETL Process Enterprise Reporting Database LDM Reporting Application

5 PAVEMENT (5) Maintain Pavement Condition Rating Segment Maintain Pavement Condition Data Extract Road Segmentation Data to Van Upload Condition Data From Van to LDM Extract TISo Data to HPMA BRIDGE (2) Provide Bridge Marker Report RAILROAD (3) Provide Bridge Traffic Report TRAFFIC (4) SAFETY (7) Maintain Traffic Safety Section Segment Provide Roadway Comparison Report Import Accident File From DPS Modify Accident Data List Erroneous Accident Record Provide Location Data Maintain Intersection/Interchange CORE LDM FUNCTIONALITY (3) Propagate Changes in the Linear Referencing System Maintain Path (Static Segments) Output Selected Data Extraction Report LDM Use Cases Provide RRXing Marker Report Provide RRXing Traffic Report Provide RRXing Accident Report Update AADT & HCADT Traffic Volumes Maintain Traffic Volume Segments Run Where s Missing Report Maintain Traffic Count Marker ROAD CHARACTERISTICS (6) Provide Static Segment Roadway Comparison Report Maintain Point of Interest Marker Maintain Roadway History Layers Extract HPMS Data Maintain Control Section Pavement Railroad Bridge Traffic Safety Road Characteristics Location Data Manager
