The Development of IEEE Standards for the Rail

The Development of IEEE Standards for the Rail Transit Industry June 2000 Thomas J. Mc. Gean, P. E.

TCRP G-4 PROGRAM • Project Begun in 1996 • Sponsored by FTA, Administered by TRB and TDC (APTA) • Approach – establish an institutional framework for developing transit standards within IEEE and ASME engineering societies – demonstrate the process by developing one or more needed standards

WHY STANDARDS? • Economics & New Technology • Safety & Regulatory Issues

• How Standards Save Money – – – • rationalize procurement process reduce “custom engineering” simplify maintenance activities reduce spare parts inventory reduce training costs Introduction of Microprocessors Makes All of These More Critical – IEEE 1473 Alone Estimated to Save NJT $420 K/year

SAFETY & SUPPORT OF REGULATORY PROCESS • Public Law 104 -113, passed in 1996, Makes it US Government Policy to Use Consensus Standards in Regulatory Activities – OMB Circular A-119 implements this law • IEEE Provides us with the Means

CONSENSUS STANDARDS PRINCIPLES • Must be present to meet PL 104 -113 – Due Process – Openness – Consensus – Balance – Right of Appeal

WHAT IEEE OFFERS THE STANDARDS DEVELOPER • Automatic ANSI Certification • Complies with PL 104 -113 & OMB A-119 • Rules, Procedures & Oversight already in place at no cost to transit industry • Professional standards experts available to assist at no cost • Large reservoir of existing case law • IEEE assumes standards liability risk

SCOPE - IEEE Rail Transit Vehicle Interface Standards Committee • “The purpose of this committee shall be to serve as the sponsor and balloting group…for all rail transit vehicle interface standards developed by the IEEE”

KEY IEEE STANDARDS PUBLISHED TO DATE • IEEE 1473 -1999 Communications Protocol • IEEE 1474. 1 -1999 Communications Based Train Control Performance & Function • IEEE 1482. 1 -1999 Event Recorder • IEEE 1475 -1999 Propulsion, Braking & Train Control IEEE 1477 -1998 Passenger Information • IEEE 1483 -2000 Software Verification • IEEE 1476 -2000 Auxiliary Power Interface • IEEE 11 -1999 Electric Motors

Other IEEE Rail Standards • • • Environmental - Being balloted Rail TCIP - Underway Battery Physical Interface - Underway Software Documentation - Underway Electronic Control - Underway Ni. Cad Battery Peformance - PAR stage HRI - PAR stage Central Control CBTC Graphic Interface - PAR stage Vehicle/Wayside Communication Protocol - Proposal

Status of Standards Activity

CONCLUSIONS • Industry now has a means to develop consensus standards for rail transit • 7 IEEE Standards Published, 8 Underway • Potential Savings of $1/3 Billion/Year
