SOURCE: 66 FR 1453, Jan. 8, 2001, unless oth-erwise noted. 940.1 Purpose. This regulation provides policies and procedures for implementing section 5206(e) of the Transpo

3、rtation Equity Act for the 21st Century (TEA21), Pub-lic Law 105178, 112 Stat. 457, pertaining to conformance with the National In-telligent Transportation Systems Ar-chitecture and Standards. 940.3 Definitions. Intelligent Transportation System (ITS) means electronics, communications, or informatio

4、n processing used singly or in combination to improve the effi-ciency or safety of a surface transpor-tation system. ITS project means any project that in whole or in part funds the acquisition of technologies or systems of tech-nologies that provide or significantly contribute to the provision of o

5、ne or more ITS user services as defined in the National ITS Architecture. Major ITS project means any ITS project that implements part of a re-gional ITS initiative that is multi-ju-risdictional, multi-modal, or otherwise affects regional integration of ITS sys-tems. National ITS Architecture (also

6、na-tional architecture) means a common framework for ITS interoperability. The National ITS Architecture com-prises the logical architecture and physical architecture which satisfy a defined set of user services. The Na-tional ITS Architecture is maintained by the United States Department of Transpo

7、rtation (DOT) and is available on the DOT web site at http:/ www.its.dot.gov. Project level ITS architecture is a framework that identifies the institu-tional agreement and technical inte-gration necessary to interface a major ITS project with other ITS projects and systems. Region is the geographic

8、al area that identifies the boundaries of the re-gional ITS architecture and is defined by and based on the needs of the par-ticipating agencies and other stake-holders. In metropolitan areas, a re-gion should be no less than the bound-aries of the metropolitan planning area. Regional ITS architectu

9、re means a re-gional framework for ensuring institu-tional agreement and technical inte-gration for the implementation of ITS projects or groups of projects. Systems engineering is a structured process for arriving at a final design of a system. The final design is selected from a number of alternat

10、ives that would accomplish the same objectives and considers the total life-cycle of the project including not only the tech-nical merits of potential solutions but also the costs and relative value of al-ternatives. 940.5 Policy. ITS projects shall conform to the Na-tional ITS Architecture and stan

11、dards in accordance with the requirements contained in this part. Conformance with the National ITS Architecture is interpreted to mean the use of the Na-tional ITS Architecture to develop a regional ITS architecture, and the sub-sequent adherence of all ITS projects to that regional ITS architectur

12、e. De-velopment of the regional ITS archi-tecture should be consistent with the transportation planning process for Statewide and Metropolitan Transpor-tation Planning. 940.7 Applicability.

(b) The Secretary may authorize ex-ceptions for: (1) Projects designed to achieve spe-cific research objectives outlined in the National ITS Program Plan under sec-tion 5205 of the TEA21, or the Surface Transportation Research and De

15、velop-ment Strategic Plan developed under 23 U.S.C. 508; or (2) The upgrade or expansion of an ITS system in existence on the date of enactment of the TEA21, if the Sec-retary determines that the upgrade or expansion: (i) Would not adversely affect the goals or purposes of Subtitle C (Intel-ligent T

16、ransportation Systems Act of 1998) of the TEA21; (ii) Is carried out before the end of the useful life of such system; and (iii) Is cost-effective as compared to alternatives that would meet the con-formity requirement of this rule. (c) These provisions do not apply to funds used for operations and

17、mainte-nance of an ITS system in existence on June 9, 1998. 940.9 Regional ITS architecture. (a) A regional ITS architecture shall be developed to guide the development of ITS projects and programs and be consistent with ITS strategies and projects contained in applicable trans-portation plans. The

18、National ITS Ar-chitecture shall be used as a resource in the development of the regional ITS architecture. The regional ITS archi-tecture shall be on a scale commensu-rate with the scope of ITS investment in the region. Provision should be made to include participation from the fol-lowing agencies,

19、 as appropriate, in the development of the regional ITS archi-tecture: Highway agencies; public safe-ty agencies (e.g., police, fire, emer-gency/medical); transit operators; Fed-eral lands agencies; State motor car-rier agencies; and other operating agencies necessary to fully address re-gional ITS

20、integration. (b) Any region that is currently im-plementing ITS projects shall have a regional ITS architecture by April 8, 2005. (c) All other regions not currently implementing ITS projects shall have a regional ITS architecture within four years of the first ITS project for that region advancing

21、to final design. (d) The regional ITS architecture shall include, at a minimum, the fol-lowing: (1) A description of the region; (2) Identification of participating agencies and other stakeholders; (3) An operational concept that iden-tifies the roles and responsibilities of participating agencies a

22、nd stake-holders in the operation and implemen-tation of the systems included in the regional ITS architecture; (4) Any agreements (existing or new) required for operations, including at a minimum those affecting ITS project interoperability, utilization of ITS re-lated standards, and the operation

23、of the projects identified in the regional ITS architecture; (5) System functional requirements; (6) Interface requirements and infor-mation exchanges with planned and ex-isting systems and subsystems (for ex-ample, subsystems and architecture flows as defined in the National ITS Architecture); (7)

24、Identification of ITS standards supporting regional and national inter-operability; and (8) The sequence of projects required for implementation. (e) Existing regional ITS architec-tures that meet all of the requirements of paragraph (d) of this section shall be considered to satisfy the requirement

25、s of paragraph (a) of this section. (f) The agencies and other stake-holders participating in the develop-ment of the regional ITS architecture shall develop and implement proce-dures and responsibilities for maintain-ing it, as needs evolve within the re-gion. 66 FR 1453, Jan. 8, 2001, as amended a

(d) Upon completion of the reg

30、ional ITS architecture required in 940.9(b) or 940.9(c), the final design of all ITS projects funded with highway trust funds shall accommodate the interface requirements and information ex-changes as specified in the regional ITS architecture. If the final design of the ITS project is inconsistent

31、with the regional ITS architecture, then the re-gional ITS architecture shall be up-dated as provided in the process defined in 940.9(f) to reflect the changes. (e) Prior to the completion of the re-gional ITS architecture, any major ITS project funded with highway trust funds that advances to final

32、 design shall have a project level ITS architec-ture that is coordinated with the devel-opment of the regional ITS architec-ture. The final design of the major ITS project shall accommodate the inter-face requirements and information ex-changes as specified in this project level ITS architecture. If

33、 the project final design is inconsistent with the project level ITS architecture, then the project level ITS architecture shall be updated to reflect the changes. The project level ITS architecture is based on the results of the systems engineer-ing analysis, and includes the fol-lowing: (1) A desc

34、ription of the scope of the ITS project; (2) An operational concept that iden-tifies the roles and responsibilities of participating agencies and stake-holders in the operation and implemen-tation of the ITS project; (3) Functional requirements of the ITS project; (4) Interface requirements and info

35、r-mation exchanges between the ITS project and other planned and existing systems and subsystems; and (5) Identification of applicable ITS standards. (f) All ITS projects funded with high-way trust funds shall use applicable ITS standards and interoperability tests that have been officially adopted

36、through rulemaking by the DOT. (g) Any ITS project that has ad-vanced to final design by April 8, 2001 is exempt from the requirements of para-graphs (d) through (f) of this section. 66 FR 1453, Jan. 8, 2001, as amended at 66 FR 19856, Apr. 18, 2001 940.13 Project administration.
