Professional Society Standards

• Jim Dietz
• Chair, Rail Transit Vehicle Interface Standards
  Committee

2
Overview

• Consensus standards process
• Benefits of standardization
• Rail Transit Vehicle Interface Standards
  Committee
• How to get involved

3
Consensus Standards Process- ANSI -

• American National Standards Institute
• Founded in 1918
• Private, non-profit organization
• Administers and coordinates U.S. voluntary
  standardization and conformity assessment system

4
Consensus Standards Process- National Standards -

• ANSI doesnt develop standards
• ANSI facilitates development
• Consensus, due process and openness
• More than 175 accredited entities
• www.ansi.org for more information

5
Consensus Standards Process- IEEE Standards
Association -

• One entity producing standards
• Audited for conformance to ANSI requirements
  (e.g. consensus)
• Standards to provide common ground for
  communication in specific areas of
  electrotechnology
• Each standard must have a sponsor

6
Consensus Standards Process- RTVISC -

• Rail Transit Vehicle Interface Standards
  Committee
• Sponsors individual standards
• Facilitates working groups
• (More on RTVISC later)

8
Benefits of Standardization- Safety -

• 2.5 billion light rail and subway passengers each
  year
• 4 times as many passengers as US airlines
• Safety has both project specific and universal
  aspects
• Draw on the whole rail community

9
Benefits of Standardization- Control Costs -

• Rail applications are known for customization
• With standardization
• Reduced design cost
• Reduced risk/contingency dollars
• Minimize single sources
• Improved reliability
• Reduced maintenance training

10
Benefits of Standardization- Regulatory
Participation -

• National Technology Transfer and Advancement Act
  (Public Law 104-113)
• Federal agencies must use, wherever possible,
  technical standards developed by consensus
  standards organizations

11
Benefits of Standardization- Credibility -

• Standards have a legal standing
• Use of standards may help manage liability

12
RTVISC- History -

• Rail Transit Vehicle Interface Standards
  Committee
• Founded in 1996 Tom McGean, Chair
• Fifty member committee
• More than 300 professionals have participated in
  working groups

13
RTVISC- Recent Transition -

• Originally funded as a Transit Cooperative
  Research Program (TCRP) project
• The process works! (no longer research)
• Funding shifted to APTA in 2002
• Chair shifted to Jim Dietz in 2002

14

Professional Society Standards- Summary -

• There is a rigorous consensus standards process
  in the US
• Professional societies are at the forefront of
  standards development
• Rail standards development activity in the US is
  very high
• Care to help?
