摘要：	Metropolitan deployment tracking uses surveys targeted at state county, and local agencies within the metropolitan planning boundary for 78 of the largest metropolitan areas. Data were gathered in this manner in 1997 and these data were updated in 1999 through a new round of surveys. As part of the 1999 data gathering, respondents were asked to estimate levels of deployment for the year 2005. This report is an extract of traffic signal data gathered through the deployment tracking project. Because the scope of data gathering is limited to the major metropolitan areas, no rural or small urban data are included. The 1999 data are draft only; results have not been reviewed for accuracy and may change. Information from 1997 and 2005 is included in some cases to provide insight into deployment trends. This is not possible in all cases, due to changes in some of the survey questions from 1997 to 1999, or in those cases where 2005 estimates are incomplete.
