Item Exploring the Application of Data Envelopment Analysis in the Evaluation of Public Transport Organizations(Springer Science and Business Media Deutschland GmbH, 2022) Praveen Kumar, P.P.; George, V.; Mulangi, R.H.The work provides details on a study on performing a comparative analysis of productivity and efficiency of selected public transport organizations in India. The data envelopment analysis (DEA) method was used in this study using sub-routines specially developed in the open-source R programming environment used in statistical analyses. The DEA approach is a commonly adopted non-parametric method of analysis for the measurement of efficiency-related characteristics. Based on the availability and consistency of information, selected input and output data on 27 State Road Transport Undertakings (SRTUs) were used in this study. The scores of efficiencies were then computed using an input-oriented DEA model with constant return to scale. Finally, the analysis was used to distinguish between efficient and inefficient SRTUs based on weights assigned to peer units. The results of this study indicate that only 10 out of the 27 SRTUs performed well. It was also found that the performance parameters could be improved by reducing the quantity of input-related parameters in order to maintain the same level of output. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.Item Assessment of Efficiency and Effectiveness of Bus Transport Organizations Using DEA Incorporating Emissions and Accidents(Institute for Transport Studies in the European Economic Integration, 2023) Praveen Kumar, P.; George, V.; Mulangi, R.H.Environmental pollution due to vehicular emissions and accidents reflect upon the sustainability, and social responsibility of transport organizations. However, it is also necessary to attain higher levels of performance by ensuring higher transit ridership measured in terms of passengers carried per day. The present work is focused on the analysis of performance efficiency and service effectiveness of 25 selected State Road Transport Undertakings (SRTUs) in India for the year 2004-05, 2009-10 and 2014-15. Here, it was proposed to use a hybrid output-oriented Data Envelopment Analysis (DEA) approach developed by Seiford and Zhu in 2002 to handle undesirable outputs such as annual Carbon-di-oxide (CO2) emitted per passenger-km, and total accidents per year in addition to overall productivity. The results of the analysis provided details on targets that could be achieved for the available input resources allocated. Transport organizations can adopt similar approaches in performance evaluation and benchmarking considering sustainability, and social responsibility along with efficiency. © 2023 Institute for Transport Studies in the European Economic Integration.
