Über dieses Buch

This book addresses the current development status of high-speed railways globally and analyzes their operational schemes and practices under emergent conditions. It covers methods and problem-solving philosophy with regard to complexity analysis, capacity evaluation, passenger-flow forecasts, operating strategies, passenger-flow allocation, resource allocation and supporting technologies in the context of serious accidents and adverse environmental influences on train operation and service organization of high-speed railways. The abnormal scenarios, emergent conditions, adverse events and corresponding theoretical and applicational solutions dealing with the train operation both in line and network scale are all from real-world cases related to and designed for Chinese high-speed railway network which is the largest in scale, the highest in complexity and the most difficult in tackling with the complex and diverse climate and geographical environment , and thus makes the book both theoretically rigorous and practically applicable. It not only helps readers consider the train and network interactions from the perspective of complexity science, but also provides them with a philosophical framework and approaches available to construct their own roadmap and problem-solving paradigms in their daily research or management. This book is suitable for researchers, postgraduates and managerial and engineering practitioners in railway-related fields, especially in high-speed railway operation and emergency management.

Chapter 1. High-Speed Railway Transportation Organization Status

Abstract
High-speed railways have developed rapidly around the world with low energy consumption, low environmental pollution, large transportation capacity, high safety, fast speed, saving land resources, and high punctuality.

Chapter 2. The Overview of the High-Speed Railway Transport Organization in Emergency

Abstract
In this chapter, the basic concepts and theories about the high-speed railway transport organization under emergency are introduced. These contents lay the foundation for comprehending the essence of the high-speed railway transport organization under emergency and provide theoretical basis and support for the methodologies described in the subsequent Chapters. Firstly, in this chapter, the essence of emergency and railway emergency is introduced. Secondly, the particularity of the high-speed railway transport organization under emergency is analyzed. Thirdly, we focus on the definition, organization principles and strategies, optimization objectives and constraints, and the process of transport organization under variety type of emergency. Finally, the complexity of transport organization under serious emergency is analyzed.

Chapter 3. Estimation of Carrying Capacity of High-Speed Railway Section in Case of Emergency

Abstract
The carrying capacity of the railway section is significantly different between emergency conditions and normal conditions. The railway transportation system will be affected to varying degrees, the types and levels of emergencies. For example, the original block mode may be degraded, due to the interruption of traffic in certain sections or the adoption of train speed limit measures, and the carrying capacity will also change dynamically with the development of the emergency. In addition, there is fuzziness in the carrying capacity under emergency conditions, due to factors such as line characteristics, train speed, signal equipment reaction time, and driver’s behavior.

Chapter 4. Rerouting Path Generation in Emergency

Abstract
Generally, there are three types of traffic paths: shortest path, specific path, and detour path (Dijkstra in Numer Math 1:269–271, 1959). The shortest path refers to the path with the shortest transportation distance among multiple paths existing between any arrival and departure station, which is adopted by passenger trains under normal operation conditions.
Limin Jia, Li Wang, Yong Qin

Chapter 5. High-Speed Railway Line Planning Under Emergency Conditions

Abstract
Different transportation organizations will be adopted under different levels of railway emergency events; for instance, serious emergencies involve the formation of line plan and train timetable. This chapter aims to comprehensively analyzeing the train operation adjustment problem under emergency conditions.
Limin Jia, Li Wang, Yong Qin

Chapter 6. Train Timetable Rescheduling for High-Speed Railway Under Emergency Conditions

Abstract
The high-speed railway train timetable rescheduling refers to the process of restoring the train orderly operation as soon as possible by rescheduling the train schedule when the train actual timetable deviates from the train scheduled timetable and the train disordered. Adjustment of high-speed railway operation plan under emergency conditions is a very complicated and important task. Establishing a complete set of relevant theories, methods, and strategies of transport organization will play a guiding role in the operation of high-speed railway trains under emergency conditions.
Limin Jia, Li Wang, Yong Qin

Chapter 7. Resource Allocation on High-Speed Railway Emergency Management

Abstract
The reasonable allocation of high-speed railway emergency resources is the basis for reducing incident response time.
Limin Jia, Li Wang, Yong Qin

Chapter 8. Emergency Resource Scheduling Optimization for High-Speed Railways

Abstract
After a railway emergency occurs, the emergency command center needs to make emergency resource scheduling decisions immediately.
Limin Jia, Li Wang, Yong Qin

Chapter 9. Decision Support System and Demonstration Application of High-Speed Railway Train Operation Under Emergency Conditions

Abstract
At present, the way that China’s railway operation management departments respond to railway emergencies still remains at the level of paper-based document inquiry and internal telephone communication, showing problems such as low efficiency of emergency response and lack of effective communication between railways.
Limin Jia, Li Wang, Yong Qin

Chapter 10. Open Question

Abstract
This chapter mainly introduces the open issues that need to be solved urgently by high-speed railway transportation organizations under the condition of emergency. These problems can be divided into three types of problems, including internal mechanism, resource allocation and information technology.
Limin Jia, Li Wang, Yong Qin
