Abstract
In the field of territory spatial planning, transportation accessibility is an important index to measure regional transportation networks. It represents how easy it is for regions to communicate with each other. As a new area of Shanghai Pilot Free Trade Zone, Lin-Gang special area will carry a huge trade market. Therefore, high demands have been put forward on both passengers and freight transport in this region. Based on GIS spatial analysis technology, this paper analyses two types of factors affecting traffic accessibility in the Lin-Gang special area. The first type is road attributes, like road length, road area, road density and road accessibility index. The second type is the spatial pattern of construction land. The results show that the transportation network in Lin-Gang special area is extremely developed, especially the southern area of Pudong International Airport, where the proportion of highway is more than half. The transportation accessibility time to Lin-Gang special area is less than two hours all over Shanghai.
