2.3.2 Other Sources of Traffic Count Data
Agencies may also have their own sets of traffic data. Cities and tolling authorities may have traffic management centers which often collect real time data about the transportation network.
Some MPOs and cities have their own traffic count databases. Cities may have an annual count program which can be a good resource for obtaining historical counts. Typically, these online databases only include ADT counts and not TMCs. Some MPOs combine counts from multiple sources such as cities and TxDOT STARS II and display it under one database. These counts may be used for planning or sketch level (macroscopic) analysis.
Some major cities, TxDOT urban areas, and cities that have traffic management centers may also have ADT or turning movement count data for their roadway facilities. These cities may conduct an annual traffic count program and collect traffic count data on their major roadways. The traffic management centers may also have data related to speed and travel time as part of their Intelligent Transportation System (ITS) network. As of 2024, the suitability and availability of speed and count data is under review by TxDOT.
Tolling agencies may also be able to provide ADT counts for locations adjacent to the toll gantries. This information can be helpful for projects involving toll lanes or managed lanes.
Pedestrian and bicycle data can be obtained through Texas A&M Transportation Institute’s (TTI’s) Texas Bicycle and Pedestrian Count Exchange (BPCX). A link to BPCX is provided in
Appendix C, Section 6 – External References (Reference 3)
. Cities and MPOs may also collect pedestrian and bicycle data. Coordinate with local jurisdictions to see what data is available.
