2.3.4 TxDOT Open Data Portal
TxDOT’s Open Data Portal is an online GIS database. The portal allows users to explore and download GIS datasets in various data formats. Users utilize queries and filters to view the information on a map on the portal. The database includes information regarding TxDOT’s roadway inventory, mile markers, most congested roadway segments, District boundaries, legislative boundaries, bridges, and more. This data may help in a planning level analysis to get information regarding a corridor or study area. The data is also downloadable and may be used to create graphics and maps to convey information in a customizable way. Some of the information on this portal can also be found on other TxDOT online data sources such as the TxDOT Statewide Planning Map and TxDOT Project Tracker.
2.3.4.1 TxDOT Statewide Planning Map
TxDOT’s Statewide Planning Map contains information on control sections, traffic counts, future traffic estimates, trunk systems, MPOs, and highways. The Statewide Planning Map displays a more selective portion of the information available on the Open Data Portal. It may be used to scan for AADTs on TxDOT roadways, determine congested areas, and find other planning level information.
2.3.4.2 TxDOT Project Tracker
TxDOT’s Project Tracker includes information on planned projects in map format. These projects are differentiated by four phases; construction underway or begins soon, construction begins within the next 4 years, construction begins within the next 5 – 10 years, or projects that are in corridor study phase or 10+ years out. Additional information is included on the map such as estimated construction cost, funding sources, and type of project.
