WSDOT - Freight Data Critical Urban and Rural Freight Corridors (NHFN)

The National Highway Freight Network (NHFN) consists of four components: 1) Primary Highway Freight System (PHFS): this is a network of highways identified as the most critical highway portions of the U.S. freight transportation system determined by measurable and objective national data; 2) Other Interstate portions not on the PHFS: these highways consistof the remaining portion of Interstate roads not included in the PHFS; 3)Critical Rural Freight Corridors (CRFCs): these are public roads not in an urbanized area which provide access and connection to the PHFS and the Interstate with other important ports, public transportation facilities, or other intermodal freight facilities; 4) Critical Urban Freight Corridors (CUFCs):these are public roads in urbanized areas which provide access and connection to the PHFSand the Interstate with other ports, public transportation facilities, or other intermodal transportation facilities. FHWA designates the PHFS, while states and in certain cases, Metropolitan Planning Organizations (MPOs), are responsible for designating public roads for the CRFCs and CUFCs in accordance with U.S.C Title 23, Section 167. In2022, WSDOT updated the Critical Urban and Rural Freight Corridor designation in collaboration with MPO and RTPO partners in Washington state. This GIS dataset provides an inventory ofthose corridors, reflecting the current designation adopted in the 2022 Washington State Freight System Plan. Another GIS dataset is also available for the PHFS and Non-PHFS Interstates, reflecting the 2022 redesignation by the FHWA. The critical urban and rural corridor designation process and criteria can be found in the 2022 Washington State Freight System Plan, appendix G: https://wsdot.wa.gov/construction-planning/statewide-plans/freight-rail-plans/freight-system-plan国家公路货运网络（National Highway Freight Network, NHFN）包含四大组成部分：1）主要公路货运系统（Primary Highway Freight System, PHFS）：该网络由经可量化客观国家级数据认定的、美国货运交通系统中最为关键的公路路段构成；2）不属于PHFS的其他州际公路路段：即未纳入PHFS的剩余州际公路路段；3）乡村关键货运走廊（Critical Rural Freight Corridors, CRFCs）：指位于非城市化区域的公共道路，用于连接PHFS与州际公路，并衔接其他重要港口、公共交通设施或多式联运货运设施；4）城市关键货运走廊（Critical Urban Freight Corridors, CUFCs）：指位于城市化区域的公共道路，用于连接PHFS与州际公路，并衔接其他港口、公共交通设施或多式联运交通设施。联邦公路管理局（Federal Highway Administration, FHWA）负责认定PHFS，而各州以及特定情形下的城市规划组织（Metropolitan Planning Organizations, MPOs）需依据《美国法典》第23编第167条，负责CRFCs与CUFCs所涉公共道路的认定工作。2022年，华盛顿州运输部（Washington State Department of Transportation, WSDOT）联合该州内的MPO及区域交通规划组织（Regional Transportation Planning Organizations, RTPO）合作伙伴，更新了城市与乡村关键货运走廊的认定结果。本地理信息系统（Geographic Information System, GIS）数据集收录了上述走廊的完整清单，反映了2022年《华盛顿州货运系统规划》所采用的最新认定标准。另有一套针对PHFS与非PHFS州际公路的GIS数据集，该数据集体现了FHWA于2022年重新认定的结果。城市与乡村关键货运走廊的认定流程及标准可查阅2022年《华盛顿州货运系统规划》附录G：https://wsdot.wa.gov/construction-planning/statewide-plans/freight-rail-plans/freight-system-plan
