This paper examines the morning commute route choice behavior of 182 drivers, using disaggregated GPS-based activity data collected during a ten-day period. This paper attempts to describe how these commuters tend to behave in the real world. A binary logit model of morning commuters’ choice between using a single commute route and multiple routes was established, based upon the evidence of dri...

A substantial literature examines the social and environmental correlates of walking to school but less addresses walking outside the school commute. Using travel diary data from London, we examined social and environmental correlates of walking: to school; outside the school commute during term time; and during the summer and weekends. Living in a household without a car was associated with al...

BACKGROUND Research has demonstrated that adolescents who actively commute have higher levels of physical activity (PA), which have declined precipitously over the past 30 years. The purpose of this study was to describe the prevalence of active commuting to school; and to identify barriers associated with active commuting. METHODS A cross-sectional study was conducted with 1672 students (46....

Introduction.-In the first part of this paper,' it was shown that the following wave equation offers a new method for describing a free particle in relativistic quantum theory: (iEps ± Mc)/M = 0, (1) where M is the operator M = m + moEk l?7kq + m'eke?7. (2) Here, m, mo, m' are any scalar hermitian operators which commute with ECk, 7ki, Pi, and in particular they may be c-numbers. The momentum o...

Previous experimental research has shown that people’s decisions can be influenced by options they have encountered in the past. This paper uses PSID data to study this phenomenon in the field, by observing how long people commute after moving between cities. It is found, as predicted, that (i) people choose longer commutes in a city they have just moved to, the longer the average commute was i...
