The Highway Performance Monitoring System (HPMS) is the authority and repository for spatially located highway data for the nation. As defined in 23 CFR 460 all State Departments of Transportation (DOT) are required to annually certify and report public road information as specified in the HPMS Field Manual. Since 1978 HPMS has provided the general public, transportation, research and academic communities with data on vehicle travel, pavement conditions, and geometric characteristics for the nation’s highways. The Office of Management and Budget (OMB) Circular A-16 identifies the United States Department of Transportation (USDOT) as the Federal Geographic Data Committee Transportation steward and the USDOT ultimately delegated stewardship to the Federal Highway Administration (FHWA). HPMS is used for Highway Trust Fund Apportionment, FHWA business needs as well as supplying data for the biannual Condition and Performance (C&P) Report to Congress. The annual Highway Statistics tables are generated using HPMS data and are vital to informing Congress and the nation on the highway system. Starting in 2010, HPMS modified the annual submission requirements to link critical highway data to a spatial network or base-map for the nation’s highways. State DOTs now annually submit both the highway attributes as well as their spatial framework to FHWA via the HPMS. The Transportation for the Nation (TFTN) Strategic Plan completed in May 2011. In the TFTN plan both the National States Geographic Information Council (NSGIC) and the USDOT Geographic Information Officer (GIO) cite HPMS as the authority for Highway Spatial Data. NSGIC is the organization that represents the Geographic Information Officers from each state and proposed a single national authoritative road network. The TFTN strategic goal calls for “producing a road centerline data set that includes all types of roads, both public and private.”[1] The Data Integration Platform (ITIP) stipulates the Spatial Highway Network in HPMS as the road network “backbone” to link major data systems at FHWA such as the National Bridge Inventory (NIB), Fiscal Management Information System (FMIS) and the RADS. The Government Accountability Office (GAO) has also called for a national geospatial network. The Spatial Highway Network’s purpose and extent are best summarized as “build once, used a many times” to support a variety of geo-located data applications that will reside in the public domain. In response to the TFTN Strategic Plan on August 7, 2012 FHWA announced that HPMS data collection, starting in 2014, would be expanded to include all public roads required under 23 CFR 460. This requirement was later entitled All Road Network of Linear Referenced Data or ARNOLD. The ARNOLD also requires that State DOTs provide facilities that are divided highways or dual carriageway as independent centerline features. Based on existing requirements for bridge inspection reporting, safety analysis, project location tracking and certified public road mileage, it is expected that States have this information or are in the process of acquiring it. Despite the availability of such data, many State DOTs will be challenged by the expanded requirement as they focus on the State owned system while local entities manage their non-State public roadways. Working with local authorities and partnering with Non State DOT organizations will be an essential component to building a cohesive spatial network of roadways as envisioned in the TFTN plan. In addition to being the national spatial highway database; HPMS also supports many transportation safety initiatives. The USDOT uses annual travel information from HPMS to establish fatality rates on US Roads. The Highway Safety Improvement Program (HSIP) is expected to capitalize on HPMS data as State DOTs collect and store data to support the Minimum Inventory of Road Elements (MIRE) program in addition to complying with ARNOLD. Moving Ahead for

The purpose of this pooled fund project is to assist States in developing one of their significant capital assets – a State-wide geospatial representation of their public road system. To build a nationwide ARNOLD this pooled fund study is open to a variety of approaches; however certain planning steps are required.

1) Strategic Planning Effort To Develop A “State-Wide All Public Roads Network” (Planning) 2) Developing A Pilot Project to Ensure the Successful Completion of A State-Wide All Public Roads Network via Planning Completed (Pilot). 3) Data Collection Activities Closely Related To Developing the All Public Network. (Optional) 4) Collection of the MIRE Fundamental Data Elements in a Format to be Linked to the ARNOLD Captured in Task 4 (Optional) 5) Assisting States in meeting the FMIS 5.0 requirement of mapping projects to the ARNOLD (FHWA-HPMS) network. (Optional) Submission Requirements: Each State has a unique set of circumstances associated with implementing the ARNOLD requirement. Therefore this study is interested in receiving submissions that enable the States to address “their” resource needs to compile with ARNOLD. The following is provided as guidance however is not intended to limit or preclude other approach submissions: -Development of a multi-stakeholder statewide strategic plan to include all public roads. -Support for efforts to revise and/or expand transportation asset management policy and procedures. -Pilot project implementation of ARNOLD. -Acquisition of local road spatial files and Safety related data. -Locating projects on the States LRS Network (as reported to HPMS) for FMIS 5.0. All submissions must specifically identify how the effort will result in the creation and maintenance of an all roads network (ARNOLD) that includes: a linear referencing system and dual carriageway features. All submissions must incorporate the work of the FHWA supported All Public Roads Geospatial Study.

The study will fund 9 State ARNOLD PFS projects. FHWA will commit $100,000.00 per State, except for Florida and California, funded at $150,000 each. Each State will match the FHWA funding of $100,000.00 - $150,000.00. The Total project will be approximately $2,000,000.00, e.g. $1,000,000.00 from the States, $1,000,000.00 from the total of the participants.
