Professional Society Standards

Jim Dietz

Chair, Rail Transit Vehicle Interface Standards Committee

for APTA Annual Meeting, 2002


Overview l.jpg
Overview

  • Consensus standards process

  • Benefits of standardization

  • Rail Transit Vehicle Interface Standards Committee

  • How to get involved

for APTA Annual Meeting, 2002


Consensus standards process ansi l.jpg
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

for APTA Annual Meeting, 2002


Consensus standards process national standards l.jpg
Consensus Standards Process- National Standards -

  • ANSI doesn’t develop standards

  • ANSI facilitates development

  • Consensus, due process and openness

  • More than 175 accredited entities

  • www.ansi.org for more information

for APTA Annual Meeting, 2002


Consensus standards process ieee standards association l.jpg
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

for APTA Annual Meeting, 2002


Consensus standards process rtvisc l.jpg
Consensus Standards Process- RTVISC -

  • Rail Transit Vehicle Interface Standards Committee

  • Sponsors individual standards

  • Facilitates working groups

    (More on RTVISC later)

for APTA Annual Meeting, 2002


Consensus standards process overview relative to ieee rail l.jpg
Consensus Standards Process- Overview relative to IEEE Rail -

for APTA Annual Meeting, 2002


Benefits of standardization safety l.jpg
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

for APTA Annual Meeting, 2002


Benefits of standardization control costs l.jpg
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

for APTA Annual Meeting, 2002


Benefits of standardization regulatory participation l.jpg
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

for APTA Annual Meeting, 2002


Benefits of standardization credibility l.jpg
Benefits of Standardization- Credibility -

  • Standards have a legal standing

  • Use of standards may help manage liability

for APTA Annual Meeting, 2002


Rtvisc history l.jpg
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

for APTA Annual Meeting, 2002


Rtvisc recent transition l.jpg
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

for APTA Annual Meeting, 2002
