Texas Statewide 2019 Data (2020 Analysis)

Texas statewide roadway performance from the 2020 reporting cycle of the Texas Top 100 Most Congested Road Segments (2019 data). Based on the 2020 roadway inventory network. Each year, the Transportation Planning and Programming (TPP) division of the Texas Department of Transportation (TxDOT) contracts with Texas A&M Transportation Institute (TTI) to calculate mobility and reliability performance measures for all roadways in the state that are functional classification 1 through 6. This data set includes these performance measures on TxDOT’s Roadway Inventory File (RIF) network.本数据集为德克萨斯州2020年报告周期内的全州道路运行绩效数据，对应榜单为德克萨斯州百大最拥堵路段（Texas Top 100 Most Congested Road Segments），数据统计基准为2019年，且依托2020年道路库存路网构建。每年，得克萨斯州运输部（Texas Department of Transportation, TxDOT）下设的运输规划与项目（Transportation Planning and Programming, TPP）部门，均会与得克萨斯农工大学运输研究所（Texas A&M Transportation Institute, TTI）签订委托合同，为该州功能分类1至6的所有道路测算通行效率与可靠性绩效指标。本数据集涵盖了得克萨斯州运输部道路库存文件（Roadway Inventory File, RIF）路网中的全部此类绩效指标。
