Abstract

This study aims to build a framework for measuring the productivity in the public transport sector through a data envelopment analysis (DEA) technique. This paper extends the Malmquist productivity index (MP1) and Luenberger productivity indicator (I.P1) evaluation with the concept of an input-oriented new slack model (NSM). NSM model measures the efficiency with the effect of slacks and satisfies unit invariance, radial and translation invariance properties. In particular, the purpose of the proposed extension is to obtain the overall productivity change in terms of technical change (Frontier Shift) and technical efficiency change (Catch-up Effect) for Rajasthan State Road Transport Corporation (RSRTC) bus depots from 2008 to 2019. For this purpose, the number of buses, number of employers, fuel consumption and route distance arc are considered input variables, while passenger-kilometres occupied and vehicle utilisation are output variables. Finally, the result demonstrates that the average total factor productivity (TFP) growth of 46 depots using MPI and LPI over the study period is 1.956% and 1.409%, respectively. This study enables policy-maker and managers to evaluate the input to reach consistent output up to an optimum level and understand the process of improving the productivity level for the bus depots.

Summary

Introduction

The public transport sector plays an essential role in increasing overall accessibility and making the environment healthier by reducing emissions and oil consumption. It helps to reduce road traffic congestion and increases economic growth. Public road transport is one of the basic requirements for commuting in rural areas at low operating costs It boosts the country’s economy, overall productivity and development by reducing transportation costs, parking facility costs, vehicle operating costs and rate of accidents. It contributed approximately 8% to GDP in 2020 (https://bit.ly/3o7Fyjv).
