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.
