Study On Transportation Corridor Configuration Of The Offshore Sea Airport

With the vigorous development of aviation industy and maturity of marine technology, offshore sea airport has got more and more attention from coastal states and regions because if its unique advantages incuding saving land, smaller noise pollution, expansion convenient and so on. Because offshore airport is isolated in the sea connecting the land by a single bridge to collect and distribute the passenger and cargo flow, so the transportation corridor will be the key of normal operation of offshore airport. In order to coordinate the various transportation means as a whole, improve transportation capacity of the offshore airport, it's necessary to do some special research in the structure deployment of the transportation corridor.This article is based on the basic theory of corridor, it analyzes the type of the structure characteristics of the offshore airport corridor, which is divided into the ground and water transportation corridor. Firstly, the characters of passengers and cargo flow on the ground transportation corridor, the characters of each kind of traffic style in the corridor and demand of water transportation corridor are analyzed, and the domestic and foreign typical type of offshore airport transportation corridor system is compared and analyzed. Then based on "four states method" theory, it forecasts the total traffic demand of ground transportation corridor of offshore airport. Then it forecasts the share responsibility rates of different traffic styles with the multinomial logit model based disaggregate theory. Based the forecasting result, it defines the peak hour's traffic curreny of ground corridor. For the water corridor, it forecasts the aviation fule demand and water passenger demand of the offshore airport. According to the traffic demand forecasting, it proposes the configuration scheme of the sea-crossing bridge, ground corridor which is connecting the aiport and city, and water corridor respectively. At last, it takes transportation corridor of Dalian Jinzhou Airport as an example and completes a practical analysis.
