In managing a traffic network, it is desirable in some case to control the traffic such that the traffic volume on a certain link does not exceed a predefined threshold (e.g. its capacity). One method is to introduce physical capacity constraints for those links. Another method is to use an asymptotic travel time function that forces the travel time of the link to approach infinity when the flo...

BACKGROUND The use of palliative radiotherapy (PRT) is variable in advanced cancer. Little is known about PRT utilization by end-of-life (EOL) cancer patients in Canada. This study examined the PRT utilization rates and factors associated with its use in a cohort of cancer patients who died in British Columbia (BC). METHODS BC residents with invasive cancer who died between April 1, 2010 and ...

The perceived public transport quality is an important driver that influences both customer satisfaction and mobility choices. The competition among transport operators needs to improve the quality of the services and identify which attributes are perceived as relevant by passengers. Among the “traditional” public transport quality attributes there are, for example: travel and waiting time, reg...

The present study seeks to examine the factors affecting information search of heads of households in purchasing an outbound package tour. A sample of 60 academics and non-academics in the field of tourism was chosen. Sampling methods were judgmental and snowball sampling. In order to gather data, we used a semi-structured interview.  Thematic analysis was applied for data analysis, and the col...

Understanding mechanisms underlie the individual’s daily time allocations is very important to understand the variability of individual’s time-space constraints and to forecast his/her daily activity participation. At most of previous studies, activity time allocation was viewed as allocating a continuous quantity (daily time budget) into multiple discrete alternatives (i.e. various activities ...

One form that mental time travel takes is fantasies about the future. Research to date has not established when people generate fantasies that depict an imagined future as particularly positive. We identify need state as a variable promoting positive fantasies about relevant stimuli (i.e., those that could address the need). In four studies, people with an aroused need (or with a stronger need)...

Introduction: It has been known for a long time in the French-speaking, but not the English-speaking literature that travel can exacerbate pre-existing psychosis. The purpose of this article was to review the literature on this subject and present recommendations for prevention. Methods: For this narrative review of the literature on travel risks in indivi...

In this paper, we propose a wave-equation-based travel-time seismic tomography method with a detailed description of its step-by-step process. First, a linear relationship between the travel-time residual 1t = T − T syn and the relative velocity perturbation δc(x)/c(x) connected by a finite-frequency travel-time sensitivity kernel K(x) is theoretically derived using the adjoint method. To accur...
