Overview
The
US Congress in 2008 mandated the deployment of Positive Train Control
(PTC) systems: advanced, wired- and wireless-networked communications
systems to prevent train-to-train collisions, enforce train speed
restrictions, and provide safety for road and railway workers.
PTC
has four primary components
-
Equipment
deployed on the locomotive/train
- Equipment
deployed trackside
- Network
access
points deployed at or near trackside that are connected to systems
operating at a remotely located control center
- A
bi-directional wireless data link that links all these elements. It
is this component upon which the Study Group shall focus.
A
presentation (IEEE 802.11-11/1032r1) was made
at both the IEEE 802.11 WNG and IEEE 802.15 WNG sessions at San
Francisco in July 2011, and the establishment of an Interest Group was
approved by the IEEE
802.15 WG during that
session. The fit with IEEE 802.15 is excellent; the released standards
and in-process work that IEEE 802.15 has done to date have addressed in
part many of the requirements for a wireless link for PTC operating in
spectrum including, but not limited to, the 216-222 MHz band. At the Atlanta Plenary in November 2011,
promotion to a full Study Group was approved. This study group will
continue to review the work that has been done and propose a
path to development of a future standard for the wireless data link
element. A liaison relationship has been established with the Rail Transportation Standards Committee of the IEEE
Vehicular Technology Society,
and similar efforts are being pursued with the Wireless Communications
Committee (WCC) of the Association of American Railroads (AAR). We
invite
participation from the broad rail
transportation communications industry.
Current
Status
The
IEEE 802.15 PTC Study Group has been meeting via a weekly telecon
since early October, while growing our membership and bringing in more
experts on rail transportation, radio technology, security and propagation.
All presentations and documents are posted on IEEE Mentor. A Call for Applications was made in early December, in order to help the Study Group to
develop final versions of the
Project Authorization Request (PAR) and Five Criteria (5C) documents.
The plan is to move to a full-fledged Task
Group by the following Interim in May 2012.
How
to participate
Participate
by attending our telecons. Our telecons are on Wednesdays approximately
every week and are currently scheduled for 1600 US Eastern.
The draft agenda, conference number and access codes will be sent out
on the
reflector at least 24 hours before the meeting time. The next IEEE
802.15 Interim meeting is at Jacksonville; until then, our
telecon dates will be: 21 December, 4 January, 11 January.
IEEE
802.15 PTC Study Group conducts their discussions on the
STDS-802-15-PTC Public Mailing List. You can learn how to subscribe to

Information
We
are in the
process of collecting submissions that provide a
good overview about the state-of-the-art in PTC efforts globally.
Document submittal is simple. If you choose to grow our library of
knowledge, please do so using the standard IEEE 802 template. Please note
that submission of copyrighted, confidential or proprietary material is
prohibited. Double check for "Confidential" or "Proprietary"
boilerplate before you push the "upload" button!
