Preface

A transportation system can be defined as the combination of elements and their interactions, which produce the demand for travel within a given area and the supply of transportation services to satisfy this demand (Ennio Cascetta, 2001). Mathematical models of transportation systems represent, for a real or hypothetical transportation system, the demand flows, the functioning of the physical or organizational elements, the interactions between them, and their effects on the external world. Mathematical models and the methods involved in their application to real, large-scale systems are thus fundamental tools for evaluating and/or designing actions affecting the physical elements(e.g., a new urban railway, new airline and terminal) and/or organizational components (e.g., a new timetable, new schedule or diagram of railway operation) of transportation systems.

This book as lecture notes has been written mainly for students in transportation engineering, logistics management and management sciences who desire to learn the basic concepts involved in the use of models for transportation systems. The materials presented is based to a large extend on courses of lectures and books delivered by authors over a number of years to students and professionals in the engineering, life, physical and social sciences. This book has mainly been edited by the author to combine different parts from the book Transportation Systems Analysis by Ennio Cascetta(2001), the lecture notes Urban Transportation Planning Modeling by Dr.Liping Fu (2012) and the online lecture notes Transportation Systems Engineering by Tom. V. Mathew and K.V. Krishna Rao(2007).

This book consists of three parts: PART A, PART B, PART C.

PART A introduces the transportation systems analysis and modeling process with 3 chapters from 1-3.

Chapter 1 discusses the basic ideas underling transportation systems and relative analysis, the materials come from the books and lectures notes by Ennio Cascetta, Tom.V.Mathew and K.V.Krishna. This chapter defines a transportation system and identifies its components. Also it describes the macroscopic measures of a traffic stream.

Chapter 2 introduces the transportation systems analysis framework for the following modeling. The materials come from lectures notes by Tom.V.Mathew and K.V.Krishna.

Chapter 3 gives general assumptions for transportation systems modeling and introduces classic mathematical models family like supply models, demand models and demand-supply interaction modeling. The materials come from the book by Ennio Cascetta.

PART B details the transportation supply analysis and modeling with 3 chapters from 4-6.

Chapter 4 discusses the macroscopic traffic stream modeling in which Greenshields model and its calibration are introduced, and presents shock waves modeling as well.

Chapter 5 introduces microscopic traffic flow modeling including car following modeling and simulation models. The materials of the two chapters come from online notes by Tom.V.Mathew and K.V.Krishna.

Chapter 6 introduces congested network trip generation analysis and modeling methods. The chapter adopted the materials of lecture notes by Dr.Liping Fu.

PART C combines with 3 chapters from 7-9. They talk about trip-based demand analysis and modeling.

Chapter 7 introduces trip distribution analysis and modeling based on Chapter 6 on trip generation, Chapter 8 discusses model split analysis and modeling, and finally Chapter 9 introduces traffic assignment analysis and modeling. The materials of these three chapters come from the lecture notes by Dr.Liping Fu.

In conclusion again, I should like to thank Dr. Ennio Cascetta, Dr. Liping Fu, Dr. Tom. V. Mathew and Dr. K.V.Krishna for their materials contribution. As well as to thank my graduate students for their typing, double checking and communication with the press.
