Human Factors Guidelines to Develop Educational Tip Cards for Aging Road Users

This project has 5 objectives. Task 1 has the objective to identify relevant theories and existing data concerning the design of public service transportation materials for aging road users. Candidate theories include embodied cognition, the integrated model of behavioral prediction, and the Communication-Human Information Processing theory about the design of warning signs. Such theories and data will be used to design tip cards for objective 2. Task 2 has the objective to produce tip cards to educate aging road users about correct actions to take for Flashing Yellow Arrow (FYA), Rectangular Rapid Flashing Beacon (RRFB), and the flashing right turn signal with pedestrian indication. These materials will be evaluated by conducting human factors usability testing stressing assessment of the dimensions of learnability, efficiency, memorability, errors, and satisfaction. We will compare standard and enhanced designs, as well as conducting experimental validation in a driving simulator study using older drivers. Task 3 has the objective, based on the outcomes of usability testing and validation, to produce guidelines for tip card generation, particularly for older road users, that attend to ordering and layout of components such as text and graphics, legibility of such materials (e.g.,fonts, color, and contrast), yielding designs that support comprehensibility and memorability. The project will also generate specific templates for tip card production (e.g., using Microsoft Office and Adobe formats). Tasks 4 and 5 will generate the Draft Final Report and closeout teleconference, and the Final report.
