In addition, the following definitions apply: *Hazard index formula* means any safety or crash prediction formula used for determining the relative risk at railway-highway crossings, taking into consideration weighted factors, and severity of crashes.
*Highway* means: ( 1 ) A road, street, or parkway and all associated elements such as a right-of-way, bridge, railway-highway crossing, tunnel, drainage structure, sign, markings, guardrail, protective structure, etc.;
( 2 ) A roadway facility as may be required by the United States Customs and Immigration Services in connection with the operation of an international bridge or tunnel; and

*Highway Safety Improvement Program (HSIP)* means a State safety program with the purpose to reduce fatalities and serious injuries on all public roads through the implementation of the provisions of 23 U.S.C. 130, 148, and 150, including the development of a data-driven Strategic Highway Safety Plan (SHSP), Railway-Highway Crossings Program, and program of highway safety improvement projects.
*Highway safety improvement project* means strategies, activities, or projects on a public road that are consistent with a State SHSP and that either correct or improve a hazardous road segment, location, or feature, or addresses a highway safety problem. Examples of projects are described in 23 U.S.C. 148(a).
*MIRE Fundamental data elements* mean the minimum subset of the roadway and traffic data elements from the FHWA's Model Inventory of Roadway Elements (MIRE) that are used to support a State's data-driven safety program.
*Public railway-highway crossing* means a railway-highway crossing where the roadway (including associated sidewalks, pathways, and shared use paths) is under the jurisdiction of and maintained by a public authority and open to public travel, including non-motorized users. All roadway approaches must be under the jurisdiction of a public roadway authority, and no roadway approach may be on private property.
*Public road* means any highway, road, or street under the jurisdiction of and maintained by a public authority and open to public travel, including non-State-owned public roads and roads on tribal land.
*Reporting year* means a 1-year period defined by the State, unless noted otherwise in this section. It may be the Federal fiscal year, State fiscal year, or calendar year.
*Railway-highway crossing protective devices* means those traffic control devices in the Manual on Uniform Traffic Control Devices (MUTCD) specified for use at such crossings; and system components associated with such traffic control devices, such as track circuit improvements and interconnections with highway traffic signals.
*Road safety audit* means a formal safety performance examination of an existing or future road or intersection by an independent multidisciplinary audit team for improving road safety for all users.
*Safety data* includes, but are not limited to, crash, roadway characteristics, and traffic data on all public roads. For railway-highway crossings, safety data also includes the characteristics of highway and train traffic, licensing, and vehicle data.
*Safety stakeholder* means, but is not limited to: ( 1 ) A highway safety representative of the Governor of the State;
( 2 ) Regional transportation planning organizations and metropolitan planning organizations, if any;
( 3 ) Representatives of major modes of transportation;
( 4 ) State and local traffic enforcement officials;
( 5 ) A highway-rail grade crossing safety representative of the Governor of the State;
( 6 ) Representatives conducting a motor carrier safety program under section 31102, 31106, or 31309 of title 49, U.S.C.;
( 7 ) Motor vehicle administration agencies;
( 8 ) County transportation officials;
( 9 ) State representatives of non-motorized users; and
( 10 ) Other Federal, State, tribal, and local safety stakeholders.
*Spot safety improvement* means an improvement or set of improvements that is implemented at a specific location on the basis of location-specific crash experience or other data-driven means.
*Strategic highway safety plan* (SHSP) means a comprehensive, multiyear, data-driven plan developed by a State department of transportation (DOT) in accordance with 23 U.S.C. 148.
*Systemic safety improvement* means a proven safety countermeasure(s) that is widely implemented based on high-risk roadway features that are correlated with particular severe crash types.
