Abstract:This report provides a framework that can be used to develop an evaluation of technology applications designed to remove barriers to transportation for people with visual, hearing, cognitive, and mobility disabilities. The framework helps evaluation teams follow a consistent process that starts with an understanding of 1) the goals of the technology; 2)the needs of the intended user population; and 3) the intended technical performance of the system, to create a logicmodel that identifies the evaluation hypotheses to be tested, the appropriate performance measures for evaluating thethose hypotheses, the data sources from which the required data can be obtained, and the areas where collaborationand agreement are needed between the evaluation team, the technology developers, and the evaluation sponsors tofinalize and perform the evaluation.The framework specifically accounts for—and provides guidance for—evaluations of a wide variety of accessibility development projects (ADP) and is designed to help project sponsors, participants, and independent evaluation (IE) teams focus their evaluation efforts on the key outcomes of importance for each ATTRI-funded ADPs being studied, while also keeping in mind the need to understand the effect the ADP has on overall trip making capabilities of users. Thus, the framework is designed for use with all types of projects sponsored by U.S. Department of Transportation’s (USDOT) ATTRI Program.
