This paper assesses the impact of environmental factors on the efficiency of public transit system within a DEAbased mixed framework. Using a sample of 100 Italian companies, we implement a two-stage method in order to investigate the impact of environmental effects into DEA inefficiency measures. The results point out the relevance of environmental effects and consequently the bias of deterministic DEA approach.
