The evaluation of the effectiveness and efficiency of the public transport system in Tunisia: Application of data envelopment analysis

The purpose of this paper is to evaluate and compare the levels of technical efficiency and effectiveness in the 12 regional companies of urban public transport in Tunisia during the period 2000-2010. To do this as a first part, we used two approaches of the data envelopment method: The input -oriented method to measure the efficiency of the public transport network and the output oriented one to judge their effectiveness. In addition, in the second part of this study, we will determine the factors that influence the efficiency of the companies. The results obtained in the first part show that the input-oriented model achieves an average efficiency slightly more beneficial than the output-oriented one (92.44% compared to 90.13%). Thus the results of the second part suggest that the length of the network is significant and positively act on pure technical efficiency. Other variables are not significant.
