Abstract:   (442 Views)
One of the most important issues in different systems is the evaluation of unit efficiency, which highly relates to its inputs and outputs. In order to compare the efficiency of different units, the inputs and outputs of those should be considered. Data envelopment analysis is a popular method for comparing the efficiency of different decision-making units, which is used in this paper.
The decision-making units of this paper are different regions of Tehran, which, by considering two inputs and two outputs in variable return to scale setting, have been used, and efficient and non-efficient regions are identified. The inputs of this model are trips that originated in the region and trips that ended in the region. The two outputs of the model are the number of accidents that led to injuries and the number of accidents that led to fatalities. In the end, the Tobit regression technique is used to identify whether the safety efficiency of regions as a dependent variable is related to the number of subway stations in that region as an independent variable.
