Roadway inventory

Roadway inventory annual data

TxDOT annually publishes its roadway inventory data in a variety of common GIS and tabular formats. Data includes GIS linework and all roadway inventory attributes. TxDOT submits this data annually to the Federal Highway Administration as part of the Highway Performance Monitoring System Program.

TxDOT also publishes a series of roadway inventory reports on an annual basis that contain statistics on the use of public roadways in the state. Statistics include miles, lane miles, daily vehicle miles of travel, and daily truck vehicle mileage of travel. These reports are summarized at county, district and state levels and are grouped by highway system, ownership, functional classification, population classification and national highway system categories. Historical chart and tabular summaries are available from 2013 forward.

Multi-year roadway data tables

TxDOT also publishes a multi-year Microsoft Excel document containing multiple data tables. Data include miles, lane miles, daily vehicle miles of travel, and daily truck vehicle mileage of travel. This document is updated annually and includes data from 2005 forward. The tables allow data to be sorted or filtered at the county, district, and state levels. Data are further broken down by population classification, route classification, highway system, functional classification, on-system route, and Metropolitan Planning Organization.
