TRB Committee ABJ80 is concerned with the appropriate application of statistical methods in the field of transportation. The committee will serve as a resource on statistical matters for all other TRB committees or activities; will foster understanding and use of statistics through dissemination and education activities; and will identify and foster research needed in statistics for use in transportation.

A Listserv were set up for the members and friends of the committee. The addresses are:
• ABJ80 Members: abj80_m@lists.asu.edu
• ABJ80 Friends: abj80_f@lists.asu.edu 

Please send email to both lists if email is intended for both groups.

Members and friends are requested to add the two email addresses to their list of trusted email addresses to ensure that the spam filters of the servers they receive their emails from would not keep them from receiving email related to the ABJ80 committee.

If you have any trouble receiving emails, please don't hesitate to contact the Committee Secretary at idavan@asu.edu or at (480)353-8400.

• Committee Website:

Your input on the committee website will be greatly appreciated. We're working on creating a useful website for the committee. Please direct website ideas/comments to both Simon Washington at Simon.Washington@asu.edu and Ida van Schalkwyk at idavan@asu.edu. Let us know if you have ideas or if you see anything missing or that can be improved.
