Progress Report. Chair McGean announced that another standard (IEEE 1482.1 Standard for Rail Transit Vehicle Event Recorder) has been approved by the IEEE for publication, bringing to four the number of standards published. Alan Rumsey has completed resolution of all comments on the CBTC standard, which is now out for a recirculation ballot. Jim Hoelscher and Claude Gabriel both have their standards out for ballot, making a total of 7 standards which have been balloted. The status of other standards activities along with the briefing by the Chair are provided as Attachment 5.
4. Coordination
FRA Regulations and Positive Train Control. (Report by Bob Heggestad) Two task forces are at work on PTC, including one concerned with standards. A master draft is being prepared. Progress is slow but steady.
FTA Task Force. FTA has formed a task force to recommend the future role for the FTA Office of Safety including considering the FTA role vis-à-vis regulation.
ASME Developments. (Report by the Chair) Stan Canjea's ASME Standards Committee on Rail Transit Vehicles held its third meeting on April 22nd in San Diego. A draft Crashworthiness Standard has been prepared and distributed to committee members for their comments. Anyone wishing to review the draft should contact Joseph Pang of the ASME at
pangj@asme.org and ask for the RT-1 draft standard. The committee intends its next meeting to be in conjunction with the APTA annual meeting in Orlando October 14-15; at that meeting they will go over the draft standard.PRESS Activities. (Report by Dave Phelps) Dave noted that Amtrak non-high speed trains are included under the PRESS area of responsibility. 14 electrical standards are now publicly available. Call Dave Phelps at 202 898 4085 or email at
dphelps@apta.com to get copies. The 14 are a mix of mandatory standards and recommended practices. APTA is the PRESS Standards Developing Organization. Dave continues to closely monitor and coordinate PRESS and RTVISC to be sure our efforts are complementary and eliminate any duplication of effort.APTA Rolling Stock Technical Forum (Formerly APTA Rolling Stock Committee). (Report by Dave Phelps) The forum met in Toronto May 25, 1999 and agreed to initiate three major projects. These include completing a new Commuter Rail Car Roster and organizing a workshop/session for next year's APTA Rapid Transit meeting in St. Louis. The forum also accepted an assignment from the APTA Rail Transit Committee to study intercar barriers required by ADA. McGean agreed to provide Phelps some information he had collected on springs used by CTA for intercar barriers. Contact Dave Phelps at APTA (202 898 4085, FAX 202 898 4019, email dphelps@apta.com) if you have information on intercar barriers to contribute.
ITS/APTA Advanced Public Transit Systems Rail Subcommittee. (Report by Lou Sanders) This group has been formed to identify ITS related development needs of the rail transit industry and further their development. They are working with the FTA Joint Program office on final guidance mandating the architecture for ITS. The group is headed by Tom Taylor of PB Systems (213 362 4769 FAX 213 362 3106, email taylorts@pbworld.com ) Contact Lou Sanders of APTA (202 898 4086 FAX 202 898 4019, email lsanders@apta.com ) if you are interested.
OMG Website. Bob diSilvestro has organized a website to discuss the advantages and disadvantages of CORBA, DCOM, and the TCIP approach to message sets. The URL is
www.ieee-omg.org A user name and password are required which can be obtained from Bob DiSilvestro at disilvestro_bob@adtranzna.comLonMark Interoperability Association. (report by Tom Sullivan) The LonMark Interoperability Association has formed a new transportation group. Gene Sansone of NYCTA chairs the group. One of the group's tasks will be to help make the IEEE1473 L protocol standard a reality. The group met in Annapolis on July 19th . Meetings are usually planned in conjunction with IEEE RTVISC meetings; the next one before our meeting in Newark New Jersey in November. Bombardier is providing critical interface documents to the group. Contact Tom Sullivan at
tjs@pacbell.net for details. The LonMark website is www.lonmark.org.Highway Rail Intersection. A critical meeting is planned for July 22-23 at the Crystal Gateway Marriott Hotel in Washington DC to define the role of HRI in the national ITS architecture. Linda Meadow (
lmeadow@earthlink.net ) is a key contact in this area.Transit Signal Priority. (Tom Sullivan) There will be a meeting in Minneapolis. The key issue is the preference to use latitude and longitude information in AVL systems to trigger signal priority. Apparently this approach has been patented by 3M. The issue is going to court.
IEC TC9 TCN Ballot. The IEC TCN protocol (IEC 61375) cited in our IEEE 1473 has been approved as an IEC standard. The U.S. didn't vote and the RTVISC wasn't notified of the pending vote or asked its opinion. McGean has discussed this with the U.S. Technical Advisor to TC9 (George Pristach) who wasn't aware of any relevant material he had received from the USNC. For further information contact George Pristach U.S. TC9 technical advisor
Pristach@PBWorld.com or Charles Zegers, Secretary of the U.S. National Committee (U.S. counterpart of IEC) c.zegers@ansi.comTransit Standards Consortium. (Dave Phelps and Eva Lerner-Lam reporting) A Transit Standards Consortium has been formed as a not-for-profit organization intended to promote and coordinate US transit standards activities. Dave reported they have received a $200,000 FTA grant.
Software Documentation Standard. (report by Paul Jamieson) The scope and purpose for a Software Documentation Standard were presented by Paul Jamieson. The scope was approved by the committee with modifications and Paul was given committee approval to submit a PAR. The approved scope is shown as Attachment 6. McGean and Jamieson will work out a purpose consistent with the approved scope. Paul will coordinate with necessary IEEE software standards committees. The next meeting of the group will be at LTK offices in New York City September 23rd and 24th.
IEEE 16 Standard. (Report by Gene Sansone) Jim Dietz is drafting a PAR and a working group has been formed. Jim will get a draft of the PAR to Tom McGean who will arrange to submit it to the IEEE. To get involved contact Jim Dietz at 215 542 0700, FAX 215 542 7676 email jdietz@ltk.com. Gene Sansone said NYCT would support this effort.
IEEE11 Ballot. Linda Sue Boehmer will find out the status of the IEEE11 ballot.
Funding for Protocol Implementation. WG1, Communications Protocols, has recommended a Gateway/TCN Demonstration Project as being desirable to reduce the P1473 Standard to practice. The project would provide evidence that the TCN standard as written is sufficient and complete by developing a North American implementation, and would also develop the gateway between TCN and Echelon needed to make P1473 a reality. A "Consortium for Communications Protocol Implementation" has been formed consisting of BART, Adtranz, Alstom, Bombardier, Echelon, Harmon Industries, Siemens, Wabco, and Union Switch and Signal and a proposal submitted to the FTA Joint Partnership Program in the Consortium's name. Letters of support are important to getting this project funded. Send them to Tom McGean (FAX 757 789 5167, email t.j.mcgean@ieeee.org Also contact chair McGean if you would like a copy of the proposal, or if your company is interested in joining the consortium. Now is the time for consortium members and others supportive of the effort to indicate their support and interest. FTA persons involved in the Joint Partnership Program include Tony Yen (202 366-0264, Don Durkee (202 366-0942) and Ed Thomas (202 366-0264). While Tom McGean has served as acting consortium coordinator, Bombardier has tentatively agreed to take over that responsibility.
NiCAD Battery Standard. The WG6 work has made clear that a NiCad battery standard for transit cars is needed. Dave Phelps will send Claude Gabriel PRESS recommended practices or standards in this area. Claude Gabriel, Stan Kwa, Tom McGean and Ted Mavronicolas need to meet to develop a recommended approach, purpose and scope. A performance standard is needed and it should make use of the PRESS work.
Information Dissemination. Linda Sue Boehmer has notified Dennis Bodson who is working with the IEEE Standards Office to see about bundling our standards so they can be purchased as a single document. Lou Sanders and Chris Jenks are working on distributing our standards to transit agencies. An article in Passenger Transport about IEEE standards is needed now.
(To facilitate followup by working group leaders activities have been organized by working group even though the agenda did not follow this approach at the actual meeting).
Definitions. Paul Jamieson Chair. A policy statement drafted by the Chair to reflect the sense of the committee on definitions is given below:
It is committee policy to use IEEE Dictionary definitions if at all possible. Further, once any definition has been balloted and accepted for use in any standard sponsored by the IEEE Rail Transit Vehicle Interface Standards Committee it shall be binding for all other standards sponsored by the committee unless it can be shown to be clearly inappropriate. If neither the IEEE Dictionary nor a RTVISC balloted standard provides a suitable definition, then the American Society of Mechanical Engineers Lexicon should be consulted for a suitable definition.. Next, standards sponsored by the ASME Rail Transit Standards Committee should be consulted. Definitions which have been balloted and accepted for any standard sponsored by the ASME Rail Transit Standards Committee shall be also binding for all IEEE RTVISC standards unless there is a different existing IEEE definition or they can be shown to be clearly inapplicable. If none of these sources produce a suitable definition, the TRB Glossary should be consulted . It should be noted that ASME and TRB Glossary definitions are not presently IEEE definitions. Thus, they should be provided in the definitions section of the IEEE standard so they can be balloted and adopted as an IEEE definition. Only when all of the above approaches has failed should a working group coin its own original definition. Since it is intended that all working groups of both IEEE RTVISC and ASME RTSC use common definitions, Working group chairs should be careful when reviewing standards prepared by other working groups, to be sure the other group's definitions will be suitable for their standard also. Paul Jamieson chairs the Definitions working group for both the IEEE RTVISC and the ASME RTSC and maintains a database with all definitions which can be downloaded from our website at www.tsd.org.
WG1 (P1473) Communications Protocols on Trains, Bob Anderson Chair. The WG1 standard IEEE 1473 has been approved by the IEEE as an official standard. Bob stressed that to fully implement his standard we will need the ongoing work of WG9 and the work for which Joint Partnership Program funding has been requested (a gateway and North American implementation of TCN).
WG2 (P1474.1) Communications Based Train Control, Alan Rumsey, Chair The P1474.1 standard ballot closed June 10th. The standard passed. All 43 votes were returned with 38 affirmative and 5 negative. The working group met in New York to resolve the comments. All negative issues have been resolved except one about whether to delete Annex C. A recirculation ballot has been mailed out covering this one negative plus 6 other substantive changes introduced in order to resolve other ballot comments. It closes August 4th. The WG2 report is included as Attachment 7.
WG3 (P1482) Rail Vehicle Monitoring and Diagnostic Systems, Linda Sue Boehmer, The Event Recorder standard has received approval from the IEEE and is now an official standard. It will be published shortly.
WG4 (P1483) Safety Standards for Software Systems, Jim Hoelscher, This standard is presently out for ballot.
WG5 (P1475) VOBC/Propulsion Controller/Motor/Brake, Dave Phelps, Chair. The WG5 standard IEEE 1475 has been approved and published by the IEEE as an official standard.
WG6 (P1476) Auxiliary Power Systems, Claude Gabriel, Chair The committee discussed the negative comments submitted by Dave Phelps as well as affirmative comments from Bob Anderson, Harvey Glickenstein, Paul Jamieson, Pat Murphy, Don Kane and Fred Perelstein.
The following action items were assigned:
With regard to sections 4.5.1 and 4.4.3, there was extensive discussion of how to handle battery terminal voltage and voltage at the load, and which was the proper focus of the standard. This issue was referred back to WG6 for resolution.
Dave Phelps negatives were all resolved. Dave is to provide a letter (email OK) to Tom McGean confirming the resolution.
SCC10 has raised an issue that Notes are not to be part of definitions which contradicts practices in our published standards. McGean is to take this up with IEEE staff.
There needs to be a meeting between Tom McGean, Claude Gabriel and Stan Kwa to better define the interface between the battery and auxiliary power standards.
McGean should transmit Fred Perelstein's editorial comments to the IEEE editor for their consideration.
McGean is to check if the IEEE 100 Dictionary should be in the references.
McGean should check if ASHRAE has a definition for "pulldown".
McGean is to check whether a table in an Informative Annex can be referred to with a "shall" in the body of the standard. (Thus making normative part of the informative annex).
Claude Gabriel is to note the resolution of all affirmative comments (accepted, rejected accepted with modified words) and whether the change is substantive or editorial. For the negative comments the resolution of each should be documented. This material should be provided to Tom McGean.
Additional comments received before the ballot closes July 23rd will be reviewed by WG6 and Chair McGean and a decision made on whether they are substantive and require committee review.
Attachment 8 provides the annotated version of the auxiliary power standard from the meeting.
WG7 P1477) Vehicle Passenger Information Standards, Lance Cooper, Chair The standard has been published as an IEEE standard. Lance had been considering whether to reactivate the committee to develop the logical interface in cooperation with Rob's WG9 and the Passenger Information work of TCIP. The committee recommends that the Psasenger Information logical interface be done as part of Rob McHugh's TCIP effort, rather than by submitting a new PAR. It asks that WG7 people work with Rob's WG9 in this area.
WG8 (P1478) Environmental Standards for Rail Transit Equipment, Chuck Elms, Chair. Chuck Elms was unable to attend the meeting. Line by Line review will be taken up at the next meeting in Newark. The following comments from the New York meeting should be incorporated into the standard.
"
Jim Hoelscher agreed to fax Chuck Elms relative humidity numbers. Chuck will obtain the ATCS environmental standards from Lou Sanders and fine tune them for use in his standard. A cautionary note will be provided for roof mounted equipment."WG9 Transit Communications Interface Profiles for Rail Transit Systems, Rob McHugh, Chair. The working group is meeting July 21 in the afternoon after this meeting concludes. WG9 effort needs to be coordinated with ROSIN-TCN, LonMark, and TCIP. All use ASN.1. Technical help will be needed to complete the registering of the data.
WG10 Battery Standard, Stanley Kwa, Chair. This new working group has held two meetings to date. The next meeting will be September 23-24, 1999 [ REVISED] at Siemens in Sacramento CA. Just physical dimensions will be standardized. Gene Sansone noted that a 5x5, 25 cell standard is used by NYCT. Participation by more midwest and western transit agencies in this working group is needed and requested. Contact Stan Kwa at 212 492 8307, Fax 212 492 8360, email CEENTS07SK@aol.com.
