WHY REDESIGN GIMS?
6
Improved Location Data
7
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.

8
External Data Maintenance
9
User Needs

• Real Time Data
• Simplified Map Views
• Meta Data
• Added Features
• Better Synchronized Data
• Simplified Data Use
• Private Features

10
Integration with LRS

• Seamless interface
• Single environment

11
HOW WILL GIMS BE DIFFERENT?
12
Normalized Data

• 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

13
Less Redundancy in Data Maintenance

• IRI
• Surface Types
• Traffic
• Location Data

14
Changes in Traditional Outputs

• Temporal Data
• Real Time Data
• External Access to Data
• Metadata

15
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.
