The Development of Standards for the Rail Transit
Industry Project TCRP G-4

• APTA Rapid Rail Conference
• June 2000 - St. Louis

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

3
WHY TCRP G-4 USES ENGINEERING SOCIETIES?

• 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 ASME assume standards liability risk

4
CONSENSUS STANDARDS PRINCIPLES

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

PROJECT FACT SHEET

• FY 00 Budget
• 175K Facilitation/Management
• 125K Transit Agency Travel
• Number of Working Groups
• IEEE 15 ASME 2
• Transit Professionals involved - 300
• 90 transit agency 100 supplier 70 consultant 40
  other
• Leverage of TCRP Dollars - 7.6/1
• Standards Published to Date - 7
• Estimated Annual Savings - 1/3 billion

6

• 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 420K/year

KEY 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
