Share Ratio Change of Public Transport in Airport Landside under the Background of Car Population Rapid Increase-A Case of Shanghai Pudong International Airport

With the rapid increase of economy and residents' income in China, the era of civil aviation massification is coming at present. As the sharp increase of traffic in airside, the shortage of transport capability in airport landside is exposed. Congestion often occurs in landside road systems and parking facilities of Chinese large airports.China is at a turning point of car population rapid increase in recent years. It gives a tough challenge to Chinese airport landside transportation systems. Therefore, it is necessary to study the developing trend and law of public and private transport in the airport landside.In this paper, the case of Shanghai Pudong International Airport, a typical airport in Mainland China is chosen. In Pudong International Airport, we investigate the main factors which affect air travelers ' choice on their ground transport modes, and the share of each landside transport mode, and compare the service level of landside transport system, and analyze the advantages and disadvantages of various transport modes.From the results of survey and investigation, we study the share changes of public transportation in the past ten years, to explore the possibility of substitution among landside transport modes, under the background of car population rapid increase. Based on these studies and explorations, we provide some suggestion on how to raise service level of public transport, which could be helpful to guide a coordinated development in the landside.
