The calculator is made in order to somehow assess the effectiveness of a taxi driver in the implementation of transportation. For example, some people can drive several hundred kilometers in a day, but at the same time earn little money. What does this mean? This suggests that most likely, the driver used the car for his own personal purposes and drove about his business.
In our company, it was customary to evaluate the efficiency of the driver's work in such a way :
Efficiency < thirty %
- the driver works poorly,
30% < Efficiency < 40% - the driver works well,
Efficiency > 40% — The driver is just handsome.
