Adjustment of Nantong Urban Rail Transit Network Planning after Introducing Important Regional Transportation Infrastructure

Abstract

Objective Under the background of regional integration of Yangtze River Delta, the introduction of important regional transportation infrastructures such as the new airport (hub) station in Nantong will not only greatly enhance the city′s external transportation capacity, but also put forward higher requirements for the urban rail transit network in Nantong. On the basis of ensuring smooth operation of urban traffic, how to realize efficient connection between urban rail transit network and external transportation hub becomes an important issue that must be faced in Nantong transportation planning. Method Through comparative analysis of the connection between external transportation hubs and urban rail transit in Nantong and in its surrounding cities,and in the light of upper planning and corresponding hub planning, the interactive relation between urban rail transit network and external transportation hub is deeply analyzed, and the connection strategy between Nantong urban rail transit network and external transportation hubs is discussed, and finally targeted connection proposals are put forward. Result & Conclusion Nantong urban rail transit network was mainly constructed with L-shaped urban rail transit lines. After adjustment, the new network planning scheme increases the number of urban rail transit lines at Nantong Station, focusing on direct connection between the southern region and Nantong Station, thus improves the access convenience of Nantong functional areas to Nantong Station, and also takes into account the connection between urban rail transit network and the new airport (hub)in Nantong.
