BACKGROUND The present study aims to increase bicycling and level of physical activity (PA), and thereby promote health in parents of toddlers, by giving access to different bicycle types. There is a need for greater understanding of e-bikes and their role in the transportation network, and further effects on PA levels and health. Moreover, longtail bikes could meet certain practical needs not ...

This paper compares bicycling in Washington, DC and Frankfurt am Main, Germany, two car-oriented cities that had adapted their urban transport system to car travel during the 20th century. Our comparative case study shows both have been successful increasing percentage of trips made by bicycle between late 1990s 2018: from 1% 5% 6% 20% trips. Both detailed bike plans specific mode share goals f...

This study proposes an architecture for an interactive motion-based traffic simulation environment. In order to enhance modeling realism involving actual human beings, the proposed architecture integrates multiple types of simulation, including: (i) motion-based driving simulation, (ii) pedestrian simulation, (iii) motorcycling and bicycling simulation, and (iv) traffic flow simulation. The arc...

Mechanical loading during physical activity produces strains within bones. It is thought that these forces provide the stimulus for the adaptation of bone. Tibial strains and rates of strain were measured in vivo in six subjects during running, stationary bicycling, leg presses and stepping and were compared with those of walking, an activity which has been found to have only a minimal effect o...

Immigrants to the United States—particularly new immigrants—are more likely than the native born to travel by bicycle. This paper explores the extent to which the use of bicycles by immigrants can be explained by variables such as income, age, automobile availability, and neighborhood characteristics. Results from multinomial logistic mode choice models suggest that, even after controlling for ...

We directly observed the prevalence of walking and bicycling (active commuting) to 8 randomly selected urban and suburban elementary schools. When school was used as the unit of analysis, only 5.0% of the students actively commuted to or from school across all observed trips. Active commuting was not affected (P >/=; 18) by school urbanization level, school socioeconomic status, time of day, da...
