Abstract:This report seeks opportunities for standardization of these data and explains findings on three principal tasks. First, it assesses the current state of standardized transportation data. By studying documentation of other programs of standardized data, including the National Transit Database (NTD) and the Highway Performance Monitoring System (HPMS), and by conducting interviews with key officials and users of these programs, we identify lessons about how transportation data are collected, compiled, disseminated, and archived. Second, this report documents the range of current practice with regard to the needed inputs to accessibility analysis. By conducting a review of documents and reports, and interviewing relevant users at various levels of government, we provide an assessment of the range of current practice with an evaluation of the characteristics and methods most appropriate for accessibility indicators. Finally, the report provides a recommended framework for standardizing the inputs to accessibility metrics. The primary goal is to eventually assemble a reliable and trustworthy data set for evaluating accessibility performance, but to do so while minimizing the burden on respondents and without suppressing the creativity and distinctiveness of initiatives at the local and regional level. We carried out interviews and focus groups with experts from several metropolitan planning organizations to respond to and modify the proposed approach to a standardized data scheme.
