OBJECTIVE Our objective was to describe how active transportation can help meet health and greenhouse gas emissions goals, and the ability of urban form strategies to impact both issues. In addition, we wanted to assess if there is an inverse relationship between active and motorized forms of travel. METHODS A cross-sectional analysis of travel diary data was used to measure relationships amo...
Parks and protected area managers use zoning to decrease interpersonal conflict between recreationists. Zoning, or segregation, of recreation-often by non-motorized and motorized activity-is designed to limit physical interaction while providing recreation opportunities to both groups. This article investigated the effectiveness of zoning to reduce recreation conflict in the Vail Pass Winter Re...
A sustainable transportation system has been defined as “one that satisfies current transport and mobility needs without compromising the ability of future generations to meet their own” (Black, 1997; Richardson, 1999). The success of sustainable transportation in urban regions depends on encouragement of non-motorized (pedestrian and cyclist) and sharedride transportation modes instead of car-...
OBJECTIVES Within the global context of the nutrition and physical activity transition it is important to determine the relationship between adiposity and active school transport (AST) across different environmental and socio-cultural settings. The present study assessed the association between adiposity (that is, body mass index z-score (BMIz), obesity, percentage body fat (PBF), waist circumf...
Drawing on individual-level mobility data from Germany between 1996 and 2009, this analysis econometrically investigates the determinants of automobile, public transit, and non-motorized travel against the backdrop of two questions: 1) Does gender play a role in determining the relative use of motor and non-motorized modes? 2) If so, how is this role mitigated or exacerbated by other socioecono...
Amid concerns for the environment and public health, there has been recently a renewed emphasis on active modes of transportation, i.e. walking and cycling. However, these modes have traditionally received research and practice focus secondary to motorized modes. There is consequently a lack of pedestrian data, in particular microscopic data, to meet the analysis and modeling needs. For instanc...
The Intelligent Transportation System (ITS) is able to make the transportation system safer, smoother, and more sustainable. The research and practice of pre-trip traveler information (PTI), an indispensable component of ITS, is very limited in China. With data collected from Zhongshan Metropolitan Area, China, this empirical study revealed the socio-demographics of potential PTI users and feas...
To overcome the limitations of the independent stacked hybrid actuator with multiple sensors, a new hybrid linear actuator combines the advantages of both technologies: piezo actuator for extremely high accuracy and motorized stage for long travel ranges. A hybrid linear actuator prototype is developed for testing in our satellite tracking antenna pointing control system. For the maximum absolu...
