A-1Â Â A P P E N D I X A Survey Questionnaire NCHRP SYNTHESIS PROJECT 20-05, TOPIC 52-11 âUSE OF SMART WORK ZONE TECHNOLOGIES FOR IMPROVING WORK ZONE SAFETYâ SURVEY LETTER TO THE RESPONDENT Dear Participant, The Transportation Research Board (TRB), through the National Cooperative Highway Research Program (NCHRP), under the sponsorship of the American Association of State Highway and Transportation Officials (AASHTO), and in cooperation with the Federal Highway Administration (FHWA) is preparing a synthesis report on the Use of Smart Work Zone Technologies for Improving Work Zone Safety. The objective of the synthesis is to review and document DOT practices regarding the use of smart work zone technologies to improve safety for motorists, construction workers, and other users of the transportation system and summarize evaluation studies of the effectiveness of these technologies. To view the scope of this synthesis, please click this link. Completion of this synthesis will assist state DOTs with identifying practices for the use of smart work zone technologies and thereby help to enhance safety in work zones for workers, drivers, and other users. Your cooperation in completing this survey will help to ensure the success of this synthesis project. This survey is being sent to one person from each state DOT. You have been identified as the appropriate person at your DOT to complete this survey. The survey link that you received is unique for your DOT. If it would be more appropriate for someone else at your DOT to take this survey, please forward the email with the survey link to them or send their name and email address to Henry Brown. Additional instructions are provided at the beginning of the survey. If you would like to download a PDF version of the survey for informational purposes, please click here.
