This book deals with alignment optimization models for planning rail transit. After a general introduction to the basics of alignment optimization theory, it presents different alignment optimization methods to deal with different situations. It shows how to set up a 3D GIS scene for alignment interaction design, including location calculation of an alignment, alignment expression in a 3D scene, and the spacial relations between geographic objects, horizontal alignment, and vertical alignment. Further, it presents methods for solving more complex alignment optimization models, and shows for each different rail transit situation, how to calculate investment, energy consumption, and environmental influence. All in all, this book offers an interesting and timely reading to both researchers and professionals in the field of optimization theory, transportation planning, and GIS.

Dynamic Analysis of High-Speed Railway Alignment: Theory and Practice elaborates on the dynamic analysis theory and method on spatial alignment parameters of high-speed railways, revealing the interaction mechanism between vehicle-track dynamic performance and track parameters of high-speed railways. It ascertains the influence rules of track structure and track geometry on vehicle-track dynamic performance, establishes the relationship models between vehicle-track dynamic performance and curve dynamic characteristic parameters, and defines the calculation relationship between lateral acceleration of car body on curves and track parameters. This book can be used as a reference book for scientific researchers, engineering technicians and management engaged in railway engineering, and will be very helpful for railway technicians who want to learn more about route planning, design, and construction and maintenance technologies of high-speed railways.

Principles of Railway Location and Design examines classification and classing methods of railway networks and expresses theories and methods of railway route selection and design. Railway networks represent modal transfer, which significantly alleviates traffic congestion and pollution The book introduces capacity enhancing methods for existing railways and implementation plans and technical conditions for improving existing passenger railways, building new high speed railways and developing heavy haul railways. The book covers ten areas of unfavorable geological conditions including slide areas, debris flow areas and earthquake areas. Practical solutions with detailed presentations have been provided. This valuable reference book summarizes and extracts the high speed railway route selection design. The book covers basic principles and methods by referring to research data of high speed railway technology in China and other countries, as well as engineering practice data.
