HOUSEKEEPING ITEMS
1.1.
Introductions
Alan Rumsey thanked Gary Pruitt and ARINC for hosting this meeting of Working Group #2 (WG2) of the Rail Transit Vehicle Interface Standards Committee (RTVISC).
1.2.
Review of Previous
WG2 Meeting Minutes
The minutes of the previous WG2 meeting held on June 6, 2001 were reviewed and accepted as written.
1.3.
Liaison with IEC TC9 "Urban Guided Transport
Management and Command/Control Systems" project (UGTMS)
Based on recommendations from WG2, the US has voted affirmatively for a new work item proposed by the IEC TC9 Railway Committee to develop a standard for Urban Guided Transport Management and Command/Control Systems (ref. IEC 9/612/NP)
Alan Rumsey (WG2 Chair) has been identified as the US representative regarding this new IEC TC9 work item.
The first working group meetings on this proposed new standard is anticipated in early 2002.
1.4.
CBTC standard to address the operation of trains
without crews (and compatibility with ASCE APM standards)
Charlie Martin, chair of the ASCE APM ATC working group, advised the WG2 participants that he had reviewed IEEE Std. 1474.1-1999 against the current ASCE APM ATC standard and was of the opinion that only minimum changes would need to be made to the IEEE standard to address the operation of trains without crews (driverless operations). He tabled a marked-up copy of IEEE Std. 1474.1-1999 indicating potential changes. He also indicated that the ASCE APM ATC standard could also be revised to ensure the ASCE standard was not in conflict with IEEE Std. 1474.1.
Tom McGean recommended that both the IEEE and ASCE working groups strive for maximum commonality between the respective standards.
Following discussion, the WG2 participants agreed that:
a) There was a need for harmonious standards
b) There should be continued liaison between the IEEE and ASCE working groups
c) There should be some degree of cross reference between the two standards
d) IEEE Std. 1474.1 should be updated for driverless operations in parallel with updates to the ASCE APM ATC standards.
Tom McGean noted that the next ASCE meeting was scheduled for October 18/19 in Washington.
1.5.
Expanded grade crossing functional requirements for
CBTC systems
Alan Rumsey tabled proposed expanded grade crossing functional requirements that had been prepared by Vic Grappone for review and comment by WG2.
1.6.
Other updates to IEEE Std. 1474.1 “CBTC Performance and
Functional Requirements”
The WG2 participants recommended that work begin immediately on the updates to IEEE Std. 1474.1, in parallel to finalizing the draft IEEE standard 1474.2. The WG2 participants indicated that they would be prepared to support 2-day WG2 meetings, as necessary, to support this objective.
1.7.
Date/Location of
Next WG2 Meeting
The next WG2 meeting was scheduled for Monday, December 10, 2001.
[Post meeting note: Next WG2 meeting will be held at TRB headquarters in Washington, D.C.]

Review of major
changes between draft D5.0 and draft D4.0.
Alan Rumsey
summarized the major changes in the latest draft of proposed standard 1474.2 that
included:
a)
Definitions of
display, display screen and window in section 3.1
b)
Description of
the CBTC ATS user interfaces in section 6.1, and
c)
Reformatting of
the CBTC ATS user interface information requirements in section 6.2
2.2.
Review of Section
6.3 “CBTC ATS user interface presentation requirements”
Sections 6.3 of the proposed Standard was reviewed in detail and a number of changes were agreed upon, as summarized below:
a) A general statement will be added to the effect that the authority having jurisdiction will define what display characteristics are to be implemented, and what display features can be changed by authority-authorized personnel. Other minor changes will be made to section 6.3.
b) In section 6.3.1.1, date format shall be “as specified by the authority having jurisdiction” and date shall be displayed “on at least one display screen at each user position”.
c) Dave Male agreed to provide proposed revised wording for Section 6.3.1.2 regarding criteria for locating a window within a display window.
d) Minor changes to section 6.3.1.3
e) The sections related to interactions with CBTC ATS control devices (sections 6.3.2.2/3/4/5) were significantly reworked and will be reformatted to clarify intent.
f) Minor changes to section 6.3.3
g) Existing section 6.3.4 (Tools for modifying display) will be deleted and replaced with a new section 6.3.4 (User help facilities); Gary Pruitt offered to prepare an initial draft for this new section.
2.3.
Review of Section 7
“Maintenance related user interface requirements”
Sections 7 of the proposed Standard was reviewed and a number of changes were agreed upon, as summarized below:
a) In section 7.1, a cross reference will be added to IEEE Std. 1474.1; additional minor changes will also be incorporated to this section.
b) In section 7.2.1, “vital” will be replaced with “essential”; additional minor changes will also be incorporated to this section
c) Section 7.3.1 will be revised to clarify that it is not the intent to exclude laptop computers; additional minor changes will also be incorporated to this section
2.4.
Review of other
sections
Other sections were briefly reviewed and a number of changes were agreed upon, as summarized below:
a) In section 2, the desirability of the statement “If the following publications are superceded by an approved revision, the revision shall apply” was questioned by a number of WG2 participants. Alan Rumsey undertook to establish to what extent WG2 could modify this “standard” RTVISC wording.
b) In section 2, the latest version of MIL-STD 1472 needs to be checked and section numbers confirmed.
c) In definition 3.1.15 it was agreed to add “by the user” to the end of this definition.
d) In section 3.2, it was agreed that the abbreviation “IEEE” could be deleted.
e) In section 5.2, “audible alarms” will be included in the last sentence.
f) In section 5.2.2.m), “train speed” will be changed to “train speed profile”
g) In section 5.2.2.p) reference will be added to the highway grade crossing warning requirements of IEEE Std. 1474.1 and equivalent user input requirements will be included in section 5.2.4
h) In section 5.2.4.g), “time and date” will be moved to section 5.2.2.
i) In section 5.3.1, date format shall be “as specified by the authority having jurisdiction”.
