Abstract:
In public transportation literature, researchers increasingly tend to evaluate the service efficiency of bus transit units in addition to their operational efficiency. Evaluation of both operational and service efficiencies provides a more comprehensive performance analysis for decision-makers. This paper proposes a non-radial data envelopment analysis (DEA) approach to measure the operational and service efficiencies simultaneously. Benefits of the proposed approach are demonstrated by applying the model to assess the performance of a bus transit company's routes. The analysis results show that the proposed approach ensures optimal operational and service efficiency scores and provides applicable input targets for each route.
