Texas Statewide 2020 Data (2021 Analysis)

Texas statewide roadway performance from the 2021 reporting cycle of the Texas Top 100 Most Congested Road Segments (2020 data). Based on the 2021 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全域道路运行绩效数据，取材自《德克萨斯州最拥堵前100条道路路段》2021年度报告周期（采用2020年统计数据），基于2021年道路路网台账网络构建。每年，德克萨斯州交通运输部（Texas Department of Transportation, TxDOT）下属的交通规划与项目（Transportation Planning and Programming, TPP）部门，均会与德克萨斯农工大学交通研究所（Texas A&M Transportation Institute, TTI）签订合同，为该州功能分类1至6级的全部道路计算通行效率与可靠性绩效指标。本数据集涵盖了德克萨斯州交通运输部道路台账文件（Roadway Inventory File, RIF）路网中的上述所有绩效指标。
