These two parameters depend on the travelling frequency and the financial status of each traveler.
Also, selection was made on the basis of a questionnaire filled up by all subjects with assistance of a relative over 18 years old, providing information regarding other gastrointestinal disorders, non-related diseases, travelling, frequency of diarrhoeal episodes, previous and current antibiotic treatment; as well as general data such as age, gender and place of residence.
Transit commuters were judged according to travel frequency of morning and evening traffic peaks.
Information such as program status, recent travel activity, "likes," travel frequency, prior or frequent destinations can be fed directly into an automated targeting model and greatly improve the precision and appeal of any offers displayed to this valuable customer such as a free room upgrade, tickets to a nearby event or a car rental.
Significant gender*genotype effects were observed in centre and side speed, distance travelled, frequency of speed over 90 mm/s, immobility frequency and duration.
Transfer cost is estimated on the basis of average distance travelled, frequency of transfers and fuel prices.
For all these assumptions, we compared simulated distance travelled, frequencies of trees visited, and revisit rates with what we actually observed in wild chimpanzees.
Among variables that reflect the factor of mode choice-related sociodemographics, the two weekend travel models (trip frequency and travel time models) found that automobile ownership greatly increases automobile travel, suggesting that the findings of weekday travel studies are applicable to weekend travel.
A comparison is made using two mode-specific travel measures: trip frequency and travel time.
It further implies that regardless of whether travel is measured by trip frequency or travel time, the argument applies to weekend travel as well as weekday travel.
Other factors may include incentives on carpooling service such as safety, time and money saving, trip purpose, age, travel frequency, disincentives on use of private vehicle and travelers' attitudes [8, 14, 21, 22, 23].
