THE POSITION AND ROLES OF PORTS AND RAILWAYS IN THE EURASIA LAND BRIDGE TRANSPORTATION IN NORTHEAST CHINA

This paper systematically analyzes and proves the favorable factors of utilizing the ports and the railways in Northeast China for the Asia-Europe land bridge transportation. It will be more beneficial to Dalian Port and HaDa (Harbin-Dalian) and Binzhou (Harbin-Manzhouli) railways in Northeast China to the Siberia railway in Russia than 1) to other ports and the corresponding railways in China, 2) to the Nakhodka Port in Russia and the corresponding railways and 3) to the Chongjin Port in North Korea and the corresponding railways. This paper also puts forward the reform measures to adopt the ports and the railways in the northeast region in China for the land bridge transportation and the problems in transportation policies and management systems.

Shunt-E 4.0—Autonomous Zero Emission Shunting Processes in Port and Hinterland Railway Operations

The port railway operation in Germany and Europe is not least due to its long history of technological and regulatory developments characterized by a high number of players and a lack of comprehensive planning and optimization of all relevant processes.Innovative technologies and business processes are therefore useful and needed to achieve key steps on the way to an overall optimization of rail transport within global supply chains.A substantial part of the European rail freight transport has its origin or its destination in an inland or sea port.Considering the railway system,ports play a more important role for urgently needed innovations than the pure interfaces between sea and land transport.Especially ports with their own railway system have an own responsibility in this matter.Insofar the goal of the Bremen Port Railway—which already now has a leading share of railway in modal split in Europe—is to exploit the opportunities offered by digitalization.Significant steps for this are the optimization and gradually automatization of rail operational processes on the last mile including modern and transparent IT systems and the designing of autonomous shunting processes.Together with research partners ISL(Institute of Shipping Economics and Logistics Bremen),BIBA(Bremen Institute for Production and Logistics)and IVE(Institute for Transport,Railway Construction and Operation in Brunswick)and in connection with associated business partners the project Rang-E has been applied for at the Ministry of Transport in the funding initiative IHATEC(Innovated HArbour TEChnologies)—and had won a grant to perform the proposed work.Basic thoughts are outlined in the following.

An overview of seismic ground motion design criteria for transportation infrastructures in USA

This paper provides an overview of current seismic ground motion criteria for transportation infrastructures in USA. This is to facilitate an understanding of current seismic performance levels and design practices in USA for transportation professionals world-wide, especially those in Asian and Pacific regions. Seismic vulnerability of a transportation infrastructure is determined by the risk associated with the seismic ground motion and specified performance criteria. Determining an acceptable seismic risk is a very complex task that must consider both social and economic aspects. Obviously, the amount of risk that a railway bridge can accept may be different from that of a highway bridge. The economic tolerance in one country may be different from that in another country for the same type of infrastructure. In this paper, seismic performance levels and design criteria of ground motion for highway bridges, railway bridges and ports＇ container wharves in USA are reviewed, and design examples are presented to demonstrate how to develop the code-based and site-specific design acceleration response spectra and time histories.
