Highlights Evaluation of the accessibility to metro feeder using public transport accessibility index (PTAI). Evaluation of the differentiated mobility needs of the marginalised for public transportation using public transport need index (PTNI). Horizontal and vertical equity measure the gap between the accessibility of public transport vis-a-vis the need. Estimation of equity of access to the existing and upcoming phases of the Bengaluru metro network. Need to incorporate equity dimension in the transport policy framework to account for differentiated transport needs.

    Abstract Equitable distribution of public transportation services is one of the Sustainable Development Goals. An evaluation of the need for and access to public transportation is therefore necessary to enable an equitable allocation of resources for the same. This paper evaluates spatial equity in the network of metro feeder buses in the city of Bengaluru in India. This network acts as the first and last-mile commuting mode for the metro lines. Accessibility of the metro feeder network from “points of interest” is measured using the Public Transportation Accessibility Index and the need for public transportation, differentiated across socio-economic groups, is estimated using the Public Transportation Need Index. The horizontal and vertical equity, which quantitatively represent the spatial distribution of metro feeder buses with respect to the transportation need, are then calculated. The results suggest access and need are well balanced in the existing metro and feeder bus network, with the exception of some areas. However, a similar analysis of the upcoming phases of the metro network highlights the specific areas in the city that will need urgent attention if access to the mass transportation services offered by the metro is to be equitable. This paper demonstrates a method to include the principles of equity in transportation planning and also a method to evaluate it in existing networks.
