TRB’2003. TRB is considering options for changing the format of the annual
meeting: actions include to try “no Thursday” sessions, “no evening” sessions,
or continue the present format. A questionnaire will be sent out to committee
chairs. In any case, except for few glitches, the web-based electronic
submission/review process is successful and will be continued in 2003. TRB
Committees will be reorganized and restructured to increase the interactions,
separate/elevate groups/modes (rail, port, and safety), and highlight the crosscutting issues. Under the new organization we will be part of the Operations &
Maintenance Group A3000 and the TFT Committee’s new number will be AHB45.
A joint, mid-year TRB meeting is planned for 2005 outside Washington, D.C. area
to allow improved interactions among committees.
The “Interactive Program Planner” on the TRB website was very useful and highly
used for meeting planning, and usable for downloading to PalmPilot. However,
the password-protected features may be improved so that users’ input can be
protected. The CD-ROM contains the 1400 papers or 95% of the papers being
presented in the PDF format. Roughly 1/3 of the papers, being presented at the
TRB’2003, will be published based on the Committee’s recommendations.
Comments were raised on how to improve the poster sessions, how to submit
discussion papers by mid-February 2003, and listserv service on TRB website.
The A3A11 committee elected to remain at the Wednesday pm schedule in 2004.
TRB Executive Committee identified and summarized the “13 Big/Critical Issues”
for possible policy studies by the committees in the Annual Report, such as
school bus safety, sustainability, etc. All 2002 TRB publications should be
available in hard copy by 01/31/2003.
Please relay all comments to “Rich Cunard” at Rcunard@nas.edu.
6. TRB Paper Review and Sessions (Hani Mahmassani)
In 2003, the A3A11 Committees received over 40 papers, and some that were
jointly reviewed with other committees. 19 presentations within 4 paper sessions
were scheduled, with 15 papers possibly being considered for publication with
required revisions. No poster session was used due to the theoretical nature of
the papers. Typically, the papers, being submitted, are sent to 5 reviewers with
an expected “rate-of-return” of three good reviews. The review chairman sends
automatically all review comments to the authors and has the option to cc all the
reviewers as well. Committee recommendations on publication will be given
02/01/2003, and the revised papers need to be submitted by 04/01/2003 to meet
the established TRB'2003 publication schedule.
All the reviewers indicated that the electronic submission/review definitely
facilitated the TRB paper review process, resulting in a higher response rate from
reviewers. It was suggested by committee members to add the capability to add
equations on the website. As usual, TRB also encourages members to submit
TRB discussion papers with advanced notice by 02/15/2003.
