Development of a Multi-Criteria Decision Method for High-Speed Rail Corridor Evaluation
High-speed intercity passenger rail projects are very complex and require many years of planning and environmental activities before construction can begin. Given the complexity of planning and environmental reviews associated with high-speed intercity passenger rail corridor planning, a systematic approach for high-level screening of various alternative routings for proposed high-speed rail co...
متن کاملSlab Track Design for High-speed
If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...
متن کاملDevelopments in High-speed Track Design
Presently high-speed tracks are built on a large scale. Although ballasted tracks are still popular, more and more slab tracks are constructed. They have some significant advantages such as low maintenance, high availability, low structure height, and low weight. The main emphasis of this paper is on the application of non-ballasted concepts for high-speed operation. Special attention is given ...
متن کاملDynamic analysis of rail track for high speed trains. 2D approach
In the framework of an ongoing national research project involving the University of Minho, the National Laboratory of Civil Engineering and the New University of Lisbon, different commercial FEM codes (DIANA, PLAXIS and ANSYS) were tested to model the dynamic performance of a high speed train track. Initially a plain strain model is considered in a robin test using experimental data from a wel...
متن کاملMulti-criteria evaluation and GIS
One of the most important applications of GIS is the display and analysis of data to support the process of environmental decision-making. A decision can be defined as a choice between alternatives, where the alternatives may be different actions, locations, objects, and the like. For example, one might need to choose which is the best location for a hazardous waste facility, or perhaps identif...
