This message is intended for metropolitan planning organizations (MPOs) and State Departments of Transportation (DOTs). Other subscribers to this listserve may ignore it. The documents announcing the Workplace Update program, and soliciting interest in participating in it, were mailed to 350 MPOs and the 50 State DOTs last week. There are three documents: an introductory letter, a short program description, and a questionnaire or order form. On the chance that some of the mail may not reach the correct people in a timely fashion, PDF versions of the documents have been copied to the TRB Subcommittee on Census Data for Transportation Planning website at http://www.mcs.com/~berwyned/census/.
