1. Introduction
Dave Gregson chaired the meeting for
Rob McHugh (a list of participants is attached). Thanks to Chris Holiday for
hosting.
2.Review of the
status of the standard
Scope and Purpose were reviewed to
highlight that they must be retained in their present form but the standard’s
emphasis is up to the group’s discretion. The other related published standards
need to be considered along with IEC-TC9 and APM work.
The latest drafts can be accessed from TSD.org, user name:transit;password:railway.
3.Review of the
section-by-section comments
The structure of the MDS as presented
in the tables at the beginning of section 4.0 in the draft standard was
discussed in detail. Train and Vehicle Bus definitions can be lifted from 1473
Fig 1. The detailed examples in the next section will elaborate the use of the
matrix.
The matrix along with some supporting
examples as presented to the full committee was simplified further.
Data logging and retrieval issues such
as media, formats, post-processing are important issues and should be addressed
in the standard.
The table of contents needs to be
updated.
4.0 Coordination
with other Working Groups
Display/display formats need to be
addressed; WG2 1474.2 paragraph 4.5
Would be a good starting point.
A reminder that
data collected by the M&DS can be stand-alone but integration into a WAN
for post processing will provide maximum benefit.
WG3 will have an informative annex of
data elements, which will be passed on to WG9 to formalize.
Christian Gerard to check if the LIRR
definitions can be used by WG3.
5.0 Next Meeting
The group expressed interest in holding the
next meeting just before the full committee in sept.
Rob has tentatively booked MUNI, 1145 Market St, at Civic Centre Station, San Francisco,
for Tues. 18th Sept.
