OBJECTIVE Commuting provides opportunities for regular physical activity which can reduce the risk of chronic disease. Commuters' mode of travel may be shaped by their environment, but understanding of which specific environmental characteristics are most important and might form targets for intervention is limited. This study investigated associations between mode choice and a range of objecti...

international travel has become increasingly common and accessible, hence, about two billion passengers undertake international and domestic air travel each year. venous thromboembolism (vte) is a serious public health disorder which may occur following prolonged travel, especially after air travel. a direct relation between vte development and prolonged travels has been documented, while some ...

BACKGROUND The purpose of this study was to assess the (previously untested) reliability and validity of survey questions commonly used to assess travel mode and travel time. METHODS Sixty-five respondents from a staff survey of travel behaviour conducted in a south-western Sydney hospital agreed to complete a travel diary for a week, wear an accelerometer over the same period, and twice comp...

The paper contains primary data based analysis on the role played by Battery Operated Auto-rickshaws in urban transportation system. Different aspects of battery operated auto-rickshaw, such as energy consumption rate, transport related emission attenuation rate, potentials of generating income and employment, trip characteristics, problems associated etc have been explored with a view to provi...

Comparing the injury risk of different travel modes requires using a travel-based measure of exposure. In this study we quantify injury risk by travel mode, age, race/ethnicity, sex, and injury severity using three different travel-based exposure measures (person-trips, person-minutes of travel, and person-miles of travel) to learn how these metrics affect the characterization of risk across po...

This paper uses an endogenous segmentation approach to model mode choice. This approach jointly determines the number of market segments in the travel population, assigns individuals probabilistically to each segment, and develops a distinct mode choice model for each segment group. The author proposes a stable and effective hybrid estimation approach for the endogenous segmentation model that ...
