3、8427, Nov. 8, 2010, unless otherwise noted. Subparts AB Reserved Subpart CReal-Time System Management Information Pro-gram 511.301 Purpose. The purpose of this part is to estab-lish the provisions and parameters for the Real-Time System Management In-formation Program. These provisions implement Sub
4、sections 1201(a)(1), (a)(2), and (c)(1) of the Safe, Account-able, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEALU) (Pub. L. 10959; 119 Stat. 1144), pertaining to Congestion Relief. 511.303 Definitions. Unless otherwise specified in this part, the definitions in 23 U.S.C
5、. 101(a) are applicable to this subpart. As used in this part: Accuracy means the measure or de-gree of agreement between a data value or set of values and a source assumed to be correct. Availability means the degree to which data values are present in the attributes (e.g., speed and travel time ar
6、e attributes of traffic) that require them. Availability is typically de-scribed in terms of percentages or num-ber of data values. Congestion means the level at which transportation system performance is unacceptable due to excessive travel times and delays. Data quality means the fitness of data f
7、or all purposes that require such data. Full construction activities mean road-way construction or maintenance ac-tivities that affect travel conditions by closing and reopening roadways or lanes. Metropolitan areas means the geo-graphic areas designated as Metropoli-tan Statistical Areas by the Off
8、ice of Management and Budget in the Execu-tive Office of the President with a pop-ulation exceeding 1,000,000 inhabitants. Real-time information program means the program by which States gather and make available the data for traffic and travel conditions. Such means may involve State-only activity
9、(including cooperative activities engaging mul-tiple State agencies), State partnership with commercial providers of value- added information products, or other effective means that enable the State to satisfy the provisions for traffic and travel time conditions reporting stated in this section. Ro
10、utes of significance are non-Inter-state roadways in metropolitan areas that are designated by States as mer-iting the collection and provision of in-formation related to traffic and travel conditions. Factors to be considered in designating routes of significance in-clude roadway safety (e.g., cras
11、h rate, routes affected by environmental events), public safety (e.g., routes used for evacuations), economic produc-tivity, severity and frequency of con-gestion, and utility of the highway to serve as a diversion route for conges-tion locations. All public roadways in-cluding arterial highways, to
12、ll facili-ties and other facilities that apply end user pricing mechanisms shall be con-sidered when designating routes of sig-nificance. In identifying these routes, States shall apply the collaborative practices and procedures that are used for compliance with 23 CFR part 940 and 23 CFR part 420.

14、porting system means a statewide system for facili-tating the real-time electronic report-ing of surface transportation incidents to a central location for use in moni-toring the event, providing accurate traveler information, and responding to the incident as appropriate. This definition is consist
15、ent with Public Law 10959; 119 Stat. 1144, Section 1201(f). Timeliness means the degree to which data values or a set of values are pro-vided at the time required or specified. Traffic and travel conditions means the characteristics that the traveling pub-lic experiences. Traffic and travel con-diti
16、ons include, but are not limited to, the following characteristics: (1) Road or lane closures because of construction, traffic incidents, or other events; (2) Roadway weather or other envi-ronmental conditions restricting or ad-versely affecting travel; and (3) Travel times or speeds on limited acce
17、ss roadways in metropolitan areas that experience recurring congestion. Validity means the degree to which data values fall within the respective domain of acceptable values. Value-added information products means crafted products intended for commercial use, for sale to a customer base, or for othe
18、r commercial enter-prise purposes. These products may be derived from information gathered by States and may be created from other party or proprietary sources. These products may be created using the unique means of the value-added infor-mation provider. 511.305 Policy. This part establishes the pr
19、ovisions and parameters for the Real-Time Sys-tem Management Information Program for State DOTs, other responsible agen-cies, and partnerships with other com-mercial entities in establishing real- time information programs that pro-vide accessibility to traffic and travel conditions information by o
20、ther public agencies, the traveling public, and by other parties who may deliver value- added information products. 511.307 Eligibility for Federal fund-ing. (a) Subject to project approval by the Secretary, a State may obligate funds apportioned to the State under Title 23 U.S.C. sections 104(b)(1)
21、, also known as National Highway System funds, 104(b)(2), also known as CMAQ Im-provement funds, and 104(b)(3), also known as STP funds, for activities re-lating to the planning, deployment and operation, including preventative maintenance, of real-time monitoring elements that advance the goals and
22、 purposes of the Real-Time System Management Information Program. The SPC funds, apportioned according to 23 U.S.C. 505(a), may be applied to the development and implementation of a real-time information program. (b) Those project applications to es-tablish a real-time information pro-gram solely fo
23、r Interstate System highways are entitled to a Federal share of 90 percent of the total project cost, pursuant to 23 U.S.C. 120(a). Those project applications to establish a real- time information program for non- Interstate highways are entitled to a Federal share of 80 percent of the total project
24、 cost, as per 23 U.S.C. 120(b). 511.309 Provisions for traffic and travel conditions reporting. (a) Minimum requirements for traffic and travel conditions made available by real-time information programs are: (1) Construction activities. The timeli-ness for the availability of information about full

(a) Requirement. States shall establish real-time information progra
34、ms that are consistent with the parameters de-fined under 511.309. The real-time in-formation program shall be established to take advantage of the existing traf-fic and travel condition monitoring ca-pabilities, and build upon them where applicable. The real-time information program shall include t

In addition, the real-time information program shall complement current transportation performance reporting systems by making it easier to gather or enhance required information. (b) Dat
36、a quality. States shall develop the methods by which data quality can be ensured to the data consumers. The criteria for defining the validity of traffic and travel conditions made available from real-time information programs shall be established by the States in collaboration with their part-ners
37、for establishing the programs. States shall receive FHWAs concur-rence that the selected methods pro-vide reasonable checks of the quality of the information made available by the real-time information program. In requesting FHWAs concurrence, the State shall demonstrate to FHWA how the selected met
38、hods gauge the accu-racy and availability of the real-time information and the remedial actions if the information quality falls below the levels described in 511.309(a)(5) and 511.309(a)(6). (c) Participation. The establishment, or the enhancement, of a real-time in-formation program should include
39、 par-ticipation from the following agencies: Highway agencies; public safety agen-cies (e.g., police, fire, emergency/med-ical); transit operators; and other oper-ating agencies necessary to sustain mobility through the region and/or the metropolitan area.

All States and regions that have created a Regional ITS Architecture in accordance with Section 940 in Title 23 CFR shall evaluate their Regional ITS Architectures to determine whether
41、the Regional ITS Architectures explic-itly address real-time highway and transit information needs and the methods needed to meet such needs. Traffic and travel conditions moni-toring needs for all Interstate system highways shall be considered. If nec-essary, the Regional ITS Architectures shall be
