Database (Format) | Relevant Attributes | Description |
---|---|---|
DCIS (Comma Separated Values - CSV) | • Project description • Spatial (county, highway, reference markers, DFO) • Temporal (fiscal year and letting dates) • Cost (construction cost estimate) | This is a statewide automated information system which allows all district offices of TxDOT to manage projects data in a consistent common format. It mostly contains highway projects funded by all the 12 categories of funding by TxDOT. |
COMPASS (Hypertext markup language - Html) | • Activity description • Spatial (county, highway) • Temporal (fiscal year and letting dates) • Cost (construction, equipment, labor, materials estimate) | The COMPASS system is the Maintenance Management Information System (MMIS) of TxDOT that allows districts to manage maintenance activities that are more routine and are usually of a smaller scope. |
Highway Inventory Data - PMIS (Excel spreadsheet - xls*) | • Spatial (county, highway, reference markers, DFO) • Road condition data (distress, ride, skid, and condition scores) • Pavement roadbed information (main lanes or frontage roads, single or divided roadbeds) • Traffic data (AADT, etc.) | PMIS is a comprehensive database on the entire network of the state-maintained highway system. It contains extensive information for each pavement section in the entire network. |
On-system Highway Network (Shapefile - shp) | • Spatial (county, highway, reference markers, DFO) • Pavement roadbed information (main lanes or frontage roads, single or divided roadbeds) | This is a “polyline” shapefile which was used as the “route event” feature dataset on which events/projects were visualized. It contains all the relevant spatial attributes and features to visualize projects in GIS. |
Auxiliary: County Boundaries and Reference Markers (Shapefile - shp) | • Spatial (county, reference markers, DFO) • County polygons | These are “polygon” and “point” shapefiles that contain the county delineations and linear reference markers respectively. |
