GIMS REDESIGN PROJECT
WHAT IS GIMS?
Geographic Information Management System
Attributed Roadway Centerlines
Business Data
• Central business data source • Centerline data source • Cartographic Support• CTAMS Input• Support for Planning Activities
and Reporting Mandates
GIMS Purpose
WHY REDESIGN GIMS?
Improved Location Data
Improved Data to Roadway Association
• Detail of features located along the roadway will increase.
• Move from capturing number of features (stop signs, curves, intersections per segment, etc.) to actual location of features.
External Data Maintenance
User Needs• Real Time Data• Simplified Map Views• Meta Data• Added Features• Better Synchronized Data• Simplified Data Use• Private Features
Integration with LRS
• Seamless interface
• Single environment
HOW WILL GIMS BE DIFFERENT?
•Data are maintained in individual tables, limiting data redundancy
•Attributes describe varying extents along a section of roadway
•Graphic representations of attribute data are generated “on the fly”
Normalized Data
Lane Width
AADT
Sufficiency Ratings
Bridges
Less Redundancy in Data Maintenance
• IRI
• Surface Types
• Traffic
• Location Data
Changes in Traditional Outputs
• Temporal Data
• Real Time Data
• External Access to Data
• Metadata
Estimated Timeline
• July 2004 – Proof of Concept for new data model completed.
• July 2005 – Ability to maintain current GIMS features in new database model.
• December 2005 – New functionality will be added to redesigned GIMS.
• July 2006 – Modules will be added for external users.
