Step Counts

Mobility management is a transportation policy aiming to change travel behavior from car use to sustainable transportation modes while increasing people’s physical activity. Providing pedometers and visualizing step counts, popular interventions in public health practice, may constitute a mobility management program. However, the ease of modal shifts and changeability of walking habits differ across neighborhood environments. Using questionnaire data from 2023 middle-aged and older participants from Yokohama, Japan, in May 2017, this study examined (1) the relationship between the physical and social environments of Yokohama Walking Point Program participants who volunteered to use free pedometers and their modal shifts from cars to walking and public transport, and (2) whether participants’ modal shifts were associated with increases in step counts. Multivariate categorical regression analyses identified the frequency of greetings and conversations with neighbors as well as health motivation as important explanatory variables in both analyses. Participants living in neighborhoods far from railway stations and in neighborhoods with a high bus stop density tended to shift to walking and public transport, a modal shift that was highly associated with increased step counts. These results suggest that mobility management should be promoted in collaboration with public health and city planning professionals.

Over the past 20 years, federal transportation policy and funding initiatives—such as the Intermodal Surface Transportation Efficiency Act of 1991; the Transportation Equity Act for the 21st Century; Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users; Transportation Investment Generating Economic Recovery Grants; and the Partnership for Sustainable Communities—have opened doors to establishing sustainable transportation policy in the United States. However, these initiatives have not always resulted in transformative change. A clear path to actionable, sustainable transportation policy requires a change within the local and regional agencies tasked with establishing and implementing the policy. This paper documents the incremental changes in departments of transportation and planning in seven American cities (Charlotte, North Carolina; Chicago, Illinois; Houston, Texas; Los Angeles, California; New York; Portland, Oregon; and Washington, D.C.) that have enabled a shift toward sustainable transportation policy. Interviews with key transportation leaders in each city revealed the methods used to implement more sustainable transport. These methods serve as a blueprint for other leaders who wish to create similar changes in their own cities.

Travel Decision

Because humans are social beings, people are members of social networks and interact with other members. As a result of social interaction, people can be influenced by the behavior of others. The present study addresses conformity behavior in activity-travel decisions, implying that in making such decisions people mimic the behavior of other members of their social networks. The presence of conformity behavior in social networks implies that sustainable behavior can be dispersed through networks. Therefore, knowing which people in a network are influential can help make a sustainable transportation policy more effective. In particular, information about the topology of social networks and geographical distribution can help maximize the policy’s spill-over effects in social and geographic spaces. This study suggests a framework to locate influential agents in relation to activity-travel decisions using three procedures: (1) estimating social distance associated with similarity in activity-travel decisions, (2) identifying influential agents by measuring centralities, and (3) exploring the spatial and activity-travel characteristics of the influential agents. The suggested framework is applied using the travel mode choices of people who had recently taken trips by road beside/alongside the Han River in Seoul, South Korea.
