Minutes of Meeting:

 

1.0  INTRODUCTIONS

 

Alan Rumsey thanked John LaForce and SEPTA for hosting this meeting of Working Group #2 (WG2) of the Rail Transit Vehicle Interface Standards Committee (RTVISC).

 

 2.0  MEETING OBJECTIVES

 

IEEE Std. 1474.1-1999, “Communications-Based Train Control Performance and Functional Requirements”, was issued by the IEEE in December 1999, following two years of effort by WG2.

 

Alan Rumsey summarized that the objective of this meeting was to determine if it is appropriate at this time for WG2 to continue its efforts to develop CBTC-related consensus standards, and if so, to develop the Scope and Purpose for such standardization initiatives. 

 

Any recommendations from this WG2 meeting will be forwarded to the full Rail Transit Vehicle Interface Standards Committee at is meeting in March.

 

(Post Meeting Note: The Conclusions/Recommendations arising from this meeting (Section 6.0 below) were presented to the full Rail Transit Vehicle Interface Standards Committee (RTVISC) at its meeting in Rancho Cucamonga, California, on March 14, 2000.  The RTVISC endorsed the WG2 Conclusions/Recommendations, as noted in the body of these minutes).

 

3.0  "BRAINSTORM" POTENTIAL NEW CBTC STANDARDS INITIATIVES

 

The following candidates were identified by WG2 as potential new CBTC standards initiatives:

 

·         "Open" Items from IEEE Std. 1474.1-1999

·         CBTC Standard to Address the Operation of Trains without Crews (ref. para 4.5)

·         Environmental Requirements for CBTC Wayside Equipment (ref. para 5.5)

·         Interoperability Interface Standards for CBTC Systems (ref. para 6.4 and original PAR 1474)

 

·        Other Proposals Submitted by WG2 Members

·         CBTC Acceptance Testing and Preventative Maintenance Standards

·         Standard for a Data Communications Subsystem for CBTC Systems

·         Standard for Definition of CBTC Data Elements

6.0  CONCLUSIONS/RECOMMENDATIONS

 

6.1  Recommendations

 

WG2 consensus recommendations, to be carried forward to the full meeting of the Rail Transit Vehicle Interface Standards Committee meeting in March, were as follows:

 

1.      Environmental standards (including EMI/EMC) should be developed for wayside CBTC equipment.  (WG8 is currently developed environmental standards for trainborne equipment).  WG2 recommendation is that WG8, or possibly a new Working Group, take on this new standard initiative.  (No chair currently identified for new Working Group).

 

(Post-meeting note: At the RTVISC meeting on March 14, 2000 the committee endorsed the above recommendation and subject to identification of a chair to lead the effort, it was agreed that a new Working Group should be established to develop environmental standards for wayside electronic equipment.  Action is with the RTVISC chair, Tom McGean, to identify a chair for the new Working Group.)

 

2.      WG2 should attempt to define graphical user interface display standards for both trainborne and central CBTC subsystems. Emphasis would be on defining information to be provided by CBTC subsystems for display purposes.  Where consensus can be reached, standard should also define form of display presentation. (It is anticipated that it would be more likely to achieve consensus on form of display for trainborne displays).  Alan Rumsey agreed to prepare a Scope and Purpose for proposed new standard for review/approval by RTVISC.  Alan Rumsey also agreed to continue as WG2 Chair for this CBTC standard initiative, if approved by the RTVISC and IEEE Standards Board.

 

(Post-meeting notes: The proposed Scope and Purpose for the new standard is as follows:

 

Proposed Scope: “This standard establishes the information to be displayed on trainborne and central graphical user interfaces in communications-based train control (CBTC) systems.”

 

Proposed Purpose: “This standard will provide for consistent trainborne and central graphical user interfaces that take advantage of the characteristics of communications-based train control (CBTC) systems to enhance service effectiveness of a rail transit system.”

 

At the RTVISC meeting on March 14, 2000, the committee endorsed the above recommendation.  WG2 was actioned to review/approve the above proposed Scope/Purpose and proceed with the development of a Project Authorization Request (PAR).)

 

3.      The existing IEEE Std. 1474.1-1999 should be updated to include an expansion of the functional requirements in paragraph 6.1.15: "Highway grade crossing warning".  The extent to which expanded grade crossing functional requirements for CBTC systems will be addressed by WG14 needs to be clarified with the RTVISC and the WG14 chair.  In the event this issue is not being addressed by WG14, and subject to RTVISC and IEEE approval, Vic Grappone agreed to develop a detailed Scope and Purpose for proposed new standard, and chair a subgroup of WG2 to develop the additional functional requirements.

 

(Post-meeting note: At the RTVISC meeting on March 14, 2000, the committee endorsed the above recommendation and it was agreed that the expansion of the highway grade crossing interface functional requirements should be undertaken as a subgroup of WG2, chaired by Vic Grappone.  If the expanded functional requirements are included in the next update to IEEE Std. 1474.1-1999, rather than a separate standard (see recommendation #4 below), then a separate Project Authorization Request (PAR) will not be required.)

 

4.      The existing IEEE Std. 1474.1-1999 should be updated to include CBTC performance and functional requirements for train operations without crews.  In general, it was the opinion of the WG2 members that the existing IEEE Std. 1474.1-1999 should be reviewed/updated in approximately 2 to 3 years time, to reflect experience of ongoing CBTC projects and CBTC system developments, and it was recommended that the update to include CBTC performance and functional requirements for train operations without crews should be incorporated at that time.

 

(Post-meeting note: At the RTVISC meeting on March 14, 2000, the committee endorsed the above recommendation subject to ensuring that the updates to include CBTC performance and functional requirements for train operations without crews was consistent with the ASCE Automated People Mover Standards.)

 

6.2  Other Conclusions

 

Other conclusions from the WG2 meeting were as follows:

 

1.      While WG2 continues to support the ultimate goal of interoperability interface standards for CBTC, the WG2 members were unable to reach sufficient consensus that this effort should be progressed at this time.  In the future, standards in the following area may also be desirable, but again there is insufficient consensus within WG2 to proceed with standards development in these areas at this time:

 

·         Standard for a Data Communications Subsystem for CBTC Systems

 

·         Standard for Definition of CBTC Data Elements

 

·         Standard for CBTC/IEEE Std. 1473 Interfaces

 

2.      There is some interest in the development of Acceptance Testing Standards for CBTC Systems, however there was insufficient consensus to proceed with such standards development at this time.  It is also unclear if such a standard would be within the IEEE mandate (rather than within the mandate of the applicable regulatory agencies).  

 

3.      There was also some interest in the development of Maintenance Standards for CBTC Systems, however there was insufficient consensus to proceed with such standards development at this time.

 

7.0  ANY OTHER BUSINESS

 

WG2 also noted the following comments:

 

·         Means of improving coordination between IEEE CBTC and NAJPTC/RSAC standard initiatives should be explored.

 

·         Means of establishing coordination between IEEE CBTC and European Urban Transit CBTC standard initiatives (UGTMS) should also be explored.
