A questionnaire (see the APPENDIX) was sent to highway agencies in all 50 states, the District of Columbia and Puerto Rico for the purpose of surveying state practices in regard to reflective sheeting purchase, usage specifications, testing, etc. The response was 100 percent and, thus, demonstrated a high degree of interest in the subject.
Responses to the questionnaire are tabulated on the attached tables. An attempt was made to report answers provided by the agencies without interpretation except in a few isolated cases where the necessafy information was available to properly relate the response to a given question. In a few instances, the agency was contacted for additional information or clarifications.
A detailed analysis of information obtained from the questionnaire, copies of specifications and purchase requisitions submitted by the respondents is intently omitted here. Instead, each contributor is invited to review the attached tables and to extract whatever information may be of value. However, the commentary and summary of findings, which follows, may be of interest.
