MISSION
The International Bridge, Tunnel and Turnpike Association (IBTTA) is the worldwide alliance of toll operators and associated industries that provides a forum for sharing knowledge and ideas to promote and enhance toll-financed transportation services.

IBTTA Data Warehouse

  • IBTTA's Data Warehouse contains the most comprehensive set of statistisics relating to toll operations. The information is gathered through extensive surveys, interviews and secondary research about toll operators and transportation agencies around the globe.  The information in the Data Warehouse is updated on an annual basis.

Proposed Changes for 2010

As 2009 comes to an end it is time to start looking forward to our 2010 data collection efforts. During 2010 the plan is to collect fewer data items than we did in 2009.  The following documents discuss those proposed changes.  The proposed changes will not become final until members have had a chance to comment on them.  Please feel free to contact Jeff Campbell with your commments.  Thank you.
