Minutes of Meeting:
1.0 HOUSEKEEPING ITEMS
1.1 Introductions
Alan Rumsey thanked Denny Pascoe and US&S for hosting this meeting of Working Group #2 (WG2) of the Rail Transit Vehicle Interface Standards Committee (RTVISC).
Alan Rumsey also specifically welcomed those participants that were attending a WG2 meeting for the first time, and provided a brief background to WG2 and the RTVISC.
1.2 Review of Previous WG2 Meeting Minutes
The minutes of the previous WG2 meeting held on February 18, 2000 were reviewed and accepted as written.
1.3 Actions Arising from Last RTVISC Meeting
The Conclusions/Recommendations arising from the WG2 meeting held on February 18, 2000 were presented to the RTVISC at its meeting in Rancho Cucamonga, California, on March 14, 2000. The RTVISC endorsed the WG2 Conclusions/Recommendations, as noted below.
1.3.1
Environmental Standard for CBTC Wayside Equipment
The RTVISC agreed that a new Working Group will be established to develop environmental standards for wayside electronic equipment. Harold Gillen has agreed to chair this new Working Group. Anyone interested in participating in this Working Group should contact Harold directly.
Where practical, meetings of this new Working Group will be scheduled at the same time/location as WG2 meetings.
1.3.2 Graphical User Interface Display Standard
The RTVISC agreed that WG2 should
define graphical user interface display standards for both trainborne and
central CBTC subsystems. Emphasis should 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. See also item
2, below.
1.3.3 Highway Grade Crossing Functional Requirements
The RTVISC agreed that 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 expanded functional requirements should be included in the next update to IEEE Std. 1474.1-1999, rather than a separate standard. This work will be undertaken by a subgroup of WG2, chaired by Vic Grappone.
Bill Petit also briefly described the scope and purpose of Working Group #14 (WG14) which is attempting to define the logical and physical interfaces and the performance attributes for the interface between the rail subsystem and the highway subsystem at a highway rail intersection. Anyone interested in participating in this working Group should contact Bill directly.
1.3.4 Operations of Trains Without Crews
The RTVISC agreed that the existing IEEE Std. 1474.1-1999 should be updated to include CBTC performance and functional requirements for train operations without crews, subject to ensuring that the updates are consistent with the ASCE Automated People Mover Standards. The existing IEEE Std. 1474.1-1999 will be reviewed/updated in approximately 2 to 3 years time, to reflect experience of ongoing CBTC projects and CBTC system developments, and the update to include CBTC performance and functional requirements for train operations without crews should be incorporated at that time.
WG2 members who are interested in this topic were invited to identify those sections of the existing IEEE Std. 1474.1-1999 that would need to be updated to support train operations without crews. (ACTION: All)
1.3.5 CBTC Interoperability
Interface Standards
It was agreed that WG2 is not yet ready to develop interoperability interface standards for CBTC and as such the existing Project Authorization Request (PAR) 1474 will be allowed to be “administratively withdrawn” by the IEEE-SA Standards Board at the end of 2000. A new PAR will be generated at the appropriate time.
1.4 Coordination Issues
1.4.1 FRA Regulations and
Positive Train Control
Bill Petit and John LaForce provided a brief status report on FRA/RSAC activities related to Positive Train Control. A notice of proposed rulemaking is being developed/reviewed but is unlikely to become an actual regulation for at least a year. Other than the fact that the FRA/RSAC approach places increased focus on risk assessment (rather than more prescriptive requirements for vital systems), no major differences were noted between the safety assurance approaches being considered by the freight railroads, and those being adopted in rail transit.
1.4.2 European Urban Transit
CBTC Standards Initiatives
Alan Rumsey advised that he was continuing to explore the possibility of closer coordination between IEEE CBTC and European Urban Transit CBTC standard initiatives (UGTMS), and hoped to report further at the next WG2 meeting.
1.5 Date/Location of Next WG2 Meeting
It was agreed that the next WG2 meeting would be held on Thursday, July 27, 2000 and would be hosted by NJ Transit (John Vogler).
(A meeting of the CBTC Peer Group, open to transit agency representatives only, was also scheduled for Friday, July 28, 2000 – also at NJ Transit.)
The following WG2 meeting was tentatively scheduled for October, 2000, in San Francisco.
2.0 USER INTERFACE STANDARD
Based on a discussion of the intent of the proposed standard, the working group participants agreed on the following title for the standard:
“User Interface Standard for Communications Based Train Control (CBTC) Systems”
2.1 Proposed Scope
The working group participants agreed on the following Scope for the proposed standard:
“This standard establishes user interface requirements in communications-based train control (CBTC) systems.”
2.2 Proposed Purpose
The working group participants agreed on the following Purpose for the proposed standard:
“This standard will provide for consistent user interfaces that take advantage of the characteristics of communications-based train control (CBTC) systems to enhance service effectiveness of a rail transit system.”
A Project Authorization Request (PAR) will be prepared based on the above title/scope/purpose and forwarded to the IEEE-SA Standards Board for Approval. (ACTION: Alan Rumsey)
The working group established a target to be in a position to ballot the proposed User Interface Standard by the end of 2001.
2.3 Implied Display Information from IEEE Std.
1474.1-1999
Alan Rumsey tabled a summary of requirements from IEEE Std. 1474.1-1999 that identified explicit information to be display on trainborne and/or central displays. The existing CBTC standard also implicitly defines other potential user interface requirements. Alan Rumsey undertook to extract these explicit and implicit requirements and incorporate into the initial draft of the User Interface Standard. (See also item 2.6 below).
2.4 Examples of CBTC Users Interfaces
John Vogler described the graphical Speed Display Unit being developed by US&S for the NJ Transit ASES project.
Alan Rumsey described the conceptual design of the Train Operator Display being developed for the NYCT Canarsie CBTC project.
Further examples of existing CBTC user interfaces will be provided for review by the working group at the next WG2 meeting, as actioned below:

2.5 Draft Table of Contents for Proposed Standard
Following discussions by the working group participants, the following tentative Table of Contents was developed for the proposed standard. This Table of Contents will be further developed/refined in subsequent working group meeting.
1. Overview
2. References
3. Abbreviations, acronyms and definitions
4. General requirements
4.1 CBTC system characteristics
4.2 General user interface requirements
5. Operations-related user interface requirements
5.1 Central CBTC subsystem
5.1.1 General
5.1.2 User interface information requirements
5.1.3 User interface presentation requirements
5.2 Trainborne CBTC subsystem
5.2.1 General
5.2.2 User interface information requirements
5.2.3 User interface presentation requirements
6. Maintenance-related user interface requirements
Alan Rumsey undertook to prepare a first draft of section 4.1. (ACTION: Alan Rumsey)
Dave Male undertook to prepare a first draft of section 4.2 by the end of June, 2000 (ACTION: Dave Male).
2.6 Discussion
The working group participants “brainstormed” potential information to be displayed on trainborne and central CBTC displays.
Based on this discussion, Alan Rumsey undertook to prepare a first draft of sections 5.1.2 and 5.2.2, and to distribute the first draft of the proposed standard to working group members by July 14, 2000, to allow time for review prior to the next WG2 meeting. (ACTION: Alan Rumsey).
3.0 ANY OTHER BUSINESS
Venkat Pindiprolu noted that the APTA Rapid Transit Conference in St. Louis, from June 1-15, 2000, included three separate sessions dedicated to CBTC.
Alan Rumsey provided information on the “Comprail 2000” conference to be held in Bologna, Italy from September 11-13, 2000.
In closing the meeting, Alan Rumsey again thanked Denny Pascoe and US&S for their hospitality.
