Demand Responsive Public Transport System in Airport Travel: Case Study of Delhi

摘要

Air travel due to its inherent advantage over other modes, is on the path of rapid growth in India. All over the world, airport travel is predominantly by private modes and Delhi is no exception. With 66% of trips by cars/taxis, the airport has started experiencing congestion whereas metro connectivity to Delhi's IGI airport suffered due to ridership issues. Literature study suggests that all over the world, there is a gradual shift to public transport (PT) in airport travel. This paper, realizing the need to increase public transport share in airport travel, attempts to understand the user behavior, reasons for preference to private transport, status of existing PT connectivity etc. and suggests feasible solution. A data intensive study was conducted at IGI. Field surveys including OD cum opinion survey with sample of 11000 passengers was done at all airport terminals of IGI, metro stations, Public Transport Center and parking lots to identify the issues that will facilitate movement from private to public transport. The paper identifies issues with existing metro connectivity and suggests demand responsive bus system with dynamic routing to fill the current PT void at IGI airport. The service, Satellite Airport Service (SAS), is proposed to connect all the terminals of IGI with major origin destination points in Delhi. The SAS service will be linked with a web-based journey planner to plan access/dispersal trips at the time of ticket booking. These measures will help in increasing share of public transport in airport travel in Delhi.
