Rob McHugh introduced himself and introductions continued around the table

Thanks to our host Bill Showalter for arranging the meeting room and equipment, and for arranging a tour of the Skyway control center

.

The minutes of meeting seven were previously reviewed by email with no changes identified. The agenda was presented as attached.

3.0 Database Format

Mike Barnett presented the consolidated Microsoft Access database program. Rob McHugh agreed to distribute this latest On-board database to facilitate the entry of working groups’ data elements. Mike also included a help table to aid in the manipulating of the database. WG9 also considers the non-Onboard TCIP type variables which are relevant business areas such as Passenger Information, Fare Collection etc.(e.g., the Vending Equipment Interface tables for Fare Collection)

Wording for the scope and purpose was reviewed again. The data dictionary will follow the guidelines of IEEE standard 1489 ; a pre-ballot copy is available on request. WG9 message set formats have yet to be determined but will follow the guidelines of IEEE standard P1488. Coordination with LONMARK and TCN will ensure as much commonality as possible. Jim Kemp suggested that WG9's title is misleading in that it implies that WG9's primary focus is data and message sets to support the national ITS initiative. The working group, and the PAR, is primarily focussed on defining the data required to make IEEE 1473 work, on board the train and to incorporate the requirements of the other RTISC WGs. The TCIP requirements should be able to be derived as a subset of the WG9 database with some external ASN.1 expert help.

5. Internet

The website: http://www.tsd.org is maintained by Tom Sullivan. Tom's site is directly linked to the IEEE site where draft standards are password protected. The user name and password for accessing draft standards are "transit" and "railway". Posted Email attachments may be in either Word 6.0/95 or Word 97. The P1488 is on the TSD website: (http://www.tsd.org/wg9.htm). It is security protected; contact Rob or Tom Sullivan for the password.

Jim Kemp will try to clarify the role of WG9 as discussed in paragraph 4 with TCIP and the Transit Standards Consortium. IEEE 1473 provides the communications protocol standard; IEEE P1544 provides the standard profiles to make sure that the information carried by the protocol can be formalized. The LonMark Interoperability Association assures internal compatibility of EIA 709 based elements and ROSIN provides the train specific engineering designed into the IEC protocol. A critical gateway between the European developed IEC protocol and the EIA protocol widely used in the US has been proposed.

ITS HRI interfaces between Rail Operations Centers and Traffic Management Centers are at too high a level for WG9. Since the available expertise within the RTVISC and the work being done by WG9 has some common basis, WG9 supports the idea that IEEE RTVISC form a new Working Group for the purpose of standardizing the above interface.

Mike Barnett presented a Unified Modeling Language(UML) models for the auxiliary power systems requirements. The WG observed that the models got very complicated as the model detail expanded. The approach was deemed to be too time consuming and complicated for the WG9 voluntary efforts. UML did have merit as a common approach which would dovetail with the higher levels of a system design.

Dave Phelps characterized WG5 data elements for entry into the database.

It was proposed that the next meeting be announced at a later date ( likely in late Jan.).

Rob will arrange a venue and finalize a date; exact date and location will be posted on http://www.tsd.org/
