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
9/22/02
for APTA Annual Meeting, 2002

4. Consensus Standards Process - National Standards -
ANSI doesn’t develop standards
ANSI facilitates development
Consensus, due process and openness
More than 175 accredited entities
for more information
9/22/02
for APTA Annual Meeting, 2002

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 )
Federal agencies must use, wherever possible, technical standards developed by consensus standards organizations

for APTA Annual Meeting, 2002

11. Benefits of Standardization - Credibility -
Standards have a legal standing
Use of standards may help manage liability

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
