5. Conclusions
This paper, indexes such as cost of expense, cost of time, cost of fatigue have been proposed to quantify levels of fastness, economy and amenity during the period of passengers’ arrival at airport and logit model has been adopted to mark and rectify parameters of different people and different traffic means so that the accessibility of arrival at airport in valid service area can be calculated. The relevant tests showed that the average arrival time of the nine large airports in Jiangsu province was 1.38 h, and 87% of the region was reachable within 1.5 h. Also, the level of accessibility of passengers to arrive at airport from southern Jiangsu province was about 30% higher than that in northern Jiangsu province due to the fact that southern Jiangsu owns developed economy and sophisticated traffic network. So for airport managers, accelerating airport external transport system construction in northern Jiangsu province, improving the density of road network and road grade and enhancing the convenience of travelers arriving at the airport are of great significance that can strengthen the airport competitiveness in northern Jiangsu province and realize the coordinated development of nine major airports in the province.
