March 14, 2000 RTVISC Meeting 4

Process

“Brainstorm” potential new initiatives Open items from IEEE Std. 1474.1-1999 Other proposals raised by WG2 members

Discussion

Establish consensus vote

March 14, 2000 RTVISC Meeting 5

Recommendation #1

Environmental standard (incl. EMI/EMC) for CBTC wayside equipment 100% of group voted on this item 100% of those that voted, voted “for”

– Recommendation is that WG8, or possibly a new WG, take on this standard initiative

– (No chair currently identified for new WG)

March 14, 2000 RTVISC Meeting 6

Recommendation #2 Graphical user interface display standard for

trainborne and central CBTC subsystems 78% of group voted on this item 95% of those that voted, voted “for”

– Emphasis would be on defining information to be provided by CBTC subsystems for display purposes. Standard may also define form of display presentation

– Alan Rumsey to prepare Scope and Purpose for proposed new standard for review/approval by RTVISC and to continue to chair WG for this new standard initiative

March 14, 2000 RTVISC Meeting 7

Recommendation #2

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.

March 14, 2000 RTVISC Meeting 8

Recommendation #3

Expand highway grade crossing functional requirements for CBTC systems 67% of group voted on this item 94% of those that voted, voted “for”

– Extent to which expanded grade crossing requirements for CBTC systems will be addressed by WG14 needs to be clarified

– If not being addressed by WG14, and subject to RTVISC approval, Vic Grappone has agreed to develop a detailed Scope and Purpose for proposed new standard, and chair a subgroup of WG2 to develop the additional functional requirements

March 14, 2000 RTVISC Meeting 9

Recommendation #4

CBTC standard to address operation of trains without crews 75% of group voted on this item 90% of those that voted, voted “for”

– 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

March 14, 2000 RTVISC Meeting 10

Other WG2 Conclusions #1

CBTC interoperability interface standards

Data Communication

System

Wayside CBTC Equipment

Trainborne CBTC Equipment

Trainborne Equipment

March 14, 2000 RTVISC Meeting 11

Other WG2 Conclusions #1

CBTC interoperability interface standard 100% of group voted on this item only 18% of those that voted, voted for

– 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 was insufficient consensus to proceed with standards development in these areas at this time:

March 14, 2000 RTVISC Meeting 12

Other WG2 Conclusions #1a

Standard for a data communications subsystem for CBTC systems only 68% of group voted on this item only 63% of those that voted, voted “for”

– Insufficient consensus within WG2 to proceed with standards development in this areas at this time

March 14, 2000 RTVISC Meeting 13

Other WG2 Conclusions #1b

Standard for definition of CBTC data elements 93% of group voted on this item only 42% of those that voted, voted “for”

– Insufficient consensus within WG2 to proceed with standards development in this areas at this time

March 14, 2000 RTVISC Meeting 14

Other WG2 Conclusions #1c

Standard for CBTC/IEEE Std. 1473 interfaces only 59% of group voted on this item only 38% of those that voted, voted “for”

– Insufficient consensus within WG2 to proceed with standards development in this areas at this time

March 14, 2000 RTVISC Meeting 15

Other WG2 Conclusions #2

Acceptance Testing Standards for CBTC Systems 79% of group voted on this item only 64% of those that voted, voted “for”

– Insufficient consensus to proceed with such standards development at this time

– It was also unclear if such a standard would be within the IEEE mandate (rather than within the mandate of the applicable regulatory agencies)

March 14, 2000 RTVISC Meeting 16

Other WG2 Conclusions #3

Maintenance Standards for CBTC Systems 71% of group voted on this item only 25% of those that voted, voted “for”

– Insufficient consensus to proceed with such standards development at this time

March 14, 2000 RTVISC Meeting 17

Other WG2 Comments

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

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