The theory of travel decision-making: A conceptual framework of active travel behavior
Summary: We present a unifying conceptual framework of active travel behavior called the theory of travel decision-making. It integrates seminal travel-related concepts from economics, geography, and psychology with active travel behavior theories and...Read more

Toward a Spatial-Temporal Measure of Land Use Mix
Summary: Urban policies have emphasized the importance of mixing land uses in a neighborhood as an intervention beholding of lasting planning and public health benefits. Transportation planning research has identified the potential of efficiency gains achieved by increasing land use mix and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity. However, despite the purported transportation...Read more

Leveraging Signal Infrastructure for Non-Motorized Counts in a Statewide Program: A Pilot Study
Summary: Transportation agencies are beginning to explore and develop non-motorized counting programs. This paper presents the results of a pilot study testing the use of existing signal infrastructure – 2070 signal controllers with advanced software to log pedestrian phase actuations and detections from...Read more
Transportation mode choice is often expressed in terms of models which assume rational choice; psychological case studies of mode adoption are comparatively rare. We present findings from a study of the psychology of adoption for sustainable transportation modes such as bicycles, car sharing, and mass transit. Case studies were conducted with current and former participants in PSU’s ‘Passport Plus’ transit pass program, as well as a longitudinal cohort study of first-time winter bicycle commuters. Composite sequence analysis was used to construct a theory of the adoption process for these modes. Our findings suggest that mode evaluation is cognitively distinct from mode selection and has different information requirements. We conclude that public and private organizations could improve the adoption rate for these modes by tailoring their communication strategies to match the commuter’s stage of adoption.
