Freight Analysis Framework (FAF5) Highway Network Assignments

The Freight Analysis Framework (FAF5) - Highway Network Assignments was created from 2017 base year and 30 year forecast data and was published on April 11, 2022 from the Bureau of Transportation Statistics (BTS) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This data package includes tabular files with results from FAF5 2017, 2022, and 2050 baseline assignments to represent freight flows by three separate truck only flows type (Total Truck, Single Unit, and Combination Unit) and three freight flow markets (domestic, import and export). 2017 and 2022 model years contain 6 data tables and 2050 model year contains 11 data tables, representing the truck only flows. Each data table can be linked to the FAF5 network geography to display truck flows by link.货运分析框架第五版（FAF5）公路网络分配数据集以2017年基准年数据与30年期预测数据为基础构建，由美国运输统计局（Bureau of Transportation Statistics, BTS）于2022年4月11日发布，隶属于美国交通部（U.S. Department of Transportation, USDOT）/美国运输统计局（BTS）国家交通地图集数据库（National Transportation Atlas Database, NTAD）。本数据包包含表格文件，收录了FAF5 2017、2022及2050年基准分配的货运流量结果，按三类卡车专属流量类型（总卡车流量、单节卡车流量、组合式卡车流量）与三类货运流量市场（国内、进口、出口）划分表征货运流量。2017年与2022年模型年份各包含6张数据表，2050年模型年份则包含11张数据表，均用于表征卡车专属流量。每张数据表均可与FAF5网络地理数据关联，以按路段展示卡车流量分布。
