Freight System

The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) freight system event polyline feature class identifies the roadway segments that are included in the National Highway Freight Network. The Fixing America's Surface Transportation (FAST) Act repealed both the Primary Freight Network and National Freight Network from Moving Ahead for Progress in the 21st Century Act (MAP-21) and directed the Federal Highway Administration (FHWA) to establish a National Highway Freight Network (NHFN) to strategically direct Federal resources toward improved performance of highway portions of the U.S. freight transportation system. The NHFN includes the following subsystems of roadways: 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. As of the 2022 Congressional re-designation of the PHFS, this network consists of about 41,799 centerline miles, including 38,014 centerline miles of Interstate and 3,785 centerline miles of non-Interstate roads. PHFS is managed by the Office of Freight Management and Operations. Other Interstate portions not on the PHFS (non-PHFS) - These highways consist of the remaining portion of Interstate roads not included in the PHFS. These routes provide important continuity and access to freight transportation facilities. These portions amount to an estimated 10,265 centerline miles of Interstate nationwide and will fluctuate with additions and deletions to the Interstate Highway System. The mileage for Non-PHFS Interstate is based on the Interstate Mileage reported in the National Highway System (NHS) and of October 17, 2019. 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. As of January 2023, there are about 5,390 centerline miles designated as CRFCs. Official record of CRFCs is with the FHWA Division Offices. Critical Urban Freight Corridors (CUFCs) - These are public roads in urbanized areas which provide access and connection to the PHFS and the Interstate with other ports, public transportation facilities, or other intermodal transportation facilities. As of January 2023, there are about 2,656 centerline miles designated as CUFCs. Official record of CUFCs is with the FHWA Division Offices. There is about 60,110 centerline miles designated on the NHFN (consisting of the PHFS, other Interstate portions not on the PHFS, the CRFCs, and the CUFCs). States and in certain cases, Metropolitan Planning Organizations (MPOs), are responsible for designating public roads for the CRFCs and CUFCs in accordance with Section 1116 of the FAST Act and the Infrastructure Investments and Jobs Act Section 11114. State designation of the CRFCs is limited to a maximum of 300 miles of highway or 20 percent of the PHFS mileage in the State, whichever is greater. State and MPO designation of the CUFCs is limited to a maximum of 150 miles of highway or 10 percent of the PHFS in the State, whichever is greater. In the case of rural states, as defined in the Infrastructure Investment and Jobs Act 11114, the mileage maximum increases to 600 miles for CRFCs or 20 percent of the PHFS mileage in the State, whichever is greater.

Metadata爱达荷州交通运输部（Idaho Transportation Department, ITD）的《道路与公路路网线性参考系统（Linear Referencing System, LRS）》货运系统事件折线要素类，用于标识纳入国家公路货运网络（National Highway Freight Network, NHFN）的道路路段。 《美国地面交通修复法案（Fixing America's Surface Transportation Act, FAST法案）》废止了《21世纪进步法案（Moving Ahead for Progress in the 21st Century Act, MAP-21）》中的“主要货运网络”与“国家货运网络”，并指示美国联邦公路管理局（Federal Highway Administration, FHWA）建立国家公路货运网络（NHFN），以统筹联邦资源，优化美国货运交通系统中公路部分的运行绩效。 国家公路货运网络包含以下道路子系统： 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组成。截至2022年国会重新划定PHFS时，该网络总里程约为41799中心英里，其中包含38014中心英里的州际公路与3785中心英里的非州际公路。PHFS由货运管理与运营办公室负责管理。 未纳入PHFS的其他州际公路路段（非PHFS州际公路）：此类公路为未被纳入PHFS的剩余州际公路路段，可为货运交通设施提供重要的连通性与可达性。此类路段全国范围内预估总里程为10265中心英里，其里程数将随州际公路系统的增减变动而波动。非PHFS州际公路的里程数据基于2019年10月17日美国国家公路系统（National Highway System, NHS）上报的州际公路里程。 重要乡村货运通道（Critical Rural Freight Corridors, CRFCs）：此类为非城市化区域的公共道路，用于连通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。截至2023年1月，共计约5390中心英里的道路被划定为CRFCs。CRFCs的官方备案由FHWA分区办公室保管。 重要城市货运通道（Critical Urban Freight Corridors, CUFCs）：此类为城市化区域的公共道路，用于连通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。截至2023年1月，共计约2656中心英里的道路被划定为CUFCs。CUFCs的官方备案由FHWA分区办公室保管。 国家公路货运网络总计划定约60110中心英里的道路，涵盖PHFS、非PHFS州际公路路段、CRFCs与CUFCs四类子系统。 各州在特定情形下由大都市规划组织（Metropolitan Planning Organizations, MPOs）负责依据《FAST法案》第1116条与《基础设施投资与就业法案》第11114条，划定CRFCs与CUFCs对应的公共道路。各州划定的CRFCs总里程不得超过本州300英里公路或本州PHFS里程的20%，以两者中数值较高者为准。各州与MPOs划定的CUFCs总里程不得超过本州150英里公路或本州PHFS里程的10%，以两者中数值较高者为准。对于《基础设施投资与就业法案》中定义的乡村州，CRFCs的里程上限提升至本州600英里公路或本州PHFS里程的20%，以两者中数值较高者为准。 该图层为从《道路与公路》系统导出的内容，仅包含LRS中的有效记录。本内容项为“规划-货运与铁路”权威要素图层的子图层。元数据。
