An online survey covering the topics discussed in the TCQSM focus groups is now available at:

The purpose of this survey is to gather input from users and potential users of the manual that will make the 3rd Edition as useful and relevant as possible to the public transportation industry. This survey will take approximately 15–20 minutes to complete and all answers will be kept confidential.

It is not necessary to have previously used the TCQSM to participate in this survey. However, if you would like additional information about the manual before beginning, PowerPoint presentations (both narrated and unnarrated) that provide background information about the manual can be viewed by clicking on the links below. (Please note that once you begin the survey it is not possible to save your responses and come back to them later.)

We would appreciate your response by Monday, February 28, 2011.

Your time and input in this process is appreciated and will be an important contribution toward developing the 3rd Edition of the manual.
