ABSTRACT
This research presents a methodology,
to calculate the amount of physical activity during the transportation. It contains
the following steps: (1) trip and activity detection (2) speed calculation (3) splitting
trips into trip-leg (4) transportation mode detection and (5) physical activity
calculation. The Global Positioning System is used to record the transport activities,
either single mode or multimode. During the trip execution, the travel behaviour
and the travel mode are also observed to obtain the physical activity levels. The
physical activity levels are calculated by taking the ratio of the Total Energy
Expenditure and the Basal Metabolic Rate. To obtain the results, an automated system
is presented which calculates the speed and also detects the mode of each trip-leg.
It also calculates the amount of physical activity. The obtained physical activity
levels for the recorded 1750 trips are unit less and range from 1.10 to 2.00. By
using the motorized transportation mode, the physical activity levels stay low and
the subject failed to achieve the recommended health guideline. The minimum value
for the moderate level of physical activity is 1.6. The requirement can be fully
achieved when the transportation mode is active i.e. walking, cycling, and performed
at moderate intensity level for at least 30 min a day.
