BACKGROUND Policy changes were needed to reshape the built environment for active transportation. METHODS Using the social ecological model as a framework, the Healthy Hawaii Initiative worked with a contractor to develop a series of meetings, planning sessions, and workshops. Activities spanned 22 months between 2007 and 2009, and involved multiple stakeholders, including educational outreac...

We conduct a cross-sectional ecological analysis to examine environmental correlates of active commuting in 39,660 urban tracts using data from the 2010 Census, 2007-2011 American Community Survey, and other sources. The five-year average (2007-2011) prevalence is 3.05% for walking, 0.63% for biking, and 7.28% for public transportation to work, with higher prevalence for all modes in lower-inco...

Los Angeles (LA) has the reputation of an auto dependent city. Although the region is served by a robust public transportation system, the majority of the population commutes by automobile and has developed in sprawling manner leading to poor air quality, traffic congestion and unsafe streets. Despite this, in recent years, the LA region has made significant headway in reversing sprawl and auto...

In this study, we successfully designed and tested a new micropump that utilizes an active check valve and bottom-protruding structure to achieve sample transportation. We performed theoretical analyses and numerical simulations to determine the optimal location of the active check valve. We also experimentally analyzed variations in the generated flow rate with respect to the pneumatic frequen...

This paper concentrates on the dualistic role of transportation as a pro-active agent of globalization and as a beneficiary of its development. Surprisingly, transportation is possibly the least researched element in the complex of factors that foster a changing world economy. The goal is to suggest areas that require an informed social science perspective based on research that will enhance th...

This effort focused on improving transportation security by making the objects (e.g. containers) being transported active agents in their own protection. Here, the objects are equipped with sensing and communication capabilities and are able to determine and communicate their sense of security throughout the dynamic transportation chain in a distributed manner. As part of the project, we have d...

INTRODUCTION Attributes of the built environment can influence active transportation, including use of public transportation. However, the relationship between perceptions of the built environment and use of public transportation deserves further attention. The objectives of this study were 1) to assess the relationship between personal characteristics and public transportation use with meeting...

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...
