Dear Colleagues:
 
TRB’s Committee on Travel Survey Methods (ABJ40) has developed the transportation community's first-ever wiki-style On-line Travel Survey Manual with details on virtually everything transportation survey developers & survey managers need to know.  Please visit http://www.travelsurveymanual.org to get a sense of the 25 extensive chapters, covering all types of transportation surveys, including household, visitor, parking, freight & establishment surveys; stated preference and qualitative surveys; GPS-based designs and data expansion; survey costs and quality control.   The newly developed Appendix provides high-quality samples of RFPs, diary forms, and other field materials.  
 
This document represents an overhaul and update of the 1996 USDOT and EPA manual prepared by Cambridge Systematics (thank you to Kevin Tierney!), with major contributions from TRB’s recent NCHRP Report 571 “Standardized Procedures for Personal Travel Surveys” (thank you to Peter Stopher & team!).
 
This document is the result of hard work and long hours by nearly 100 volunteers.  Thank you  to everyone who participated in this effort.  
Of course, a wiki-style project means that no one is “in charge” of checking all contents (unlike a contract, where the PI is responsible).  There are many ways that this document can be improved, including corrections and updates, and we would love your editing contributions!
 
We want to keep this document up to date, especially with field materials, such as samples of RFPs, respondent diaries, and CATI scripts.  With the advent of so many computer-based surveys, we hope survey crews will capture (via video images) & upload computer screen survey interfaces.  
 
We hope that you will find this document useful, and we look forward to your help improving and updating it.    For permission to edit chapters, please contact Lei Zhang (lei@umd.edu) or Krishnan Viswanathan (kviswanathan@camsys.com), so that they can provide you the appropriate login information.

 Please pass the word along.
 
Thanks so much,
 
Kara Kockelman, Krishnan Viswanathan, Elaine Murakami, Lei Zhang, Kevin Tierney & the rest of the Travel Survey Manual Gang
