Business Problem

GIS is used to better manage the assets of UDOT. UDOT needs to know data on assets (i.e. stop signs), how many there are, where they are, and what condition are they in. When UDOT has this information, a budget can be formed that allows for needed replacement or improvements.

GIS can be utilized identify high accident rate locations. The visualization of the data gives safety engineers the information required to quickly identify problem locations.

Departmental data, such as traffic volumes, snowplow routes and pavement condition can now be viewed geographically to aid in the management of the transportation infrastructure. Statewide Transportation Improvement Projects (STIP) project locations can be located on maps dynamically on the Internet to provide the public with specific information.

UDOT uses GIS to aid in the management of roadside vegetation. The vegetation along the roadside is a large issue. When re-vegetation efforts are required due to cuts in the soil or excavation, UDOT needs to know what to plant to return the area to the original vegetation. Some vegetation species are considered invasive weeds and effective controls need to be applied, while some species are endangered and require protection.

Technology Implemented

Multiple technologies are being used in building solutions. ArcInfo, Arcview, ArcIMS, Visual Basic, ASP and GPS data collection are being used in concert to collect, store, display and analyze departmental data.
