| Summary | Traffic flow theory is a social science that studies "traffic behaviors" and a fundamental subject in the field of transportation. This monograph attempts to systematically compile and delineate the core issues pertaining to the modeling aspects of traffic flow theory.
Since the launch of the first car model by Henry Ford in 1908, specifically Model T, and its successful manufacturing of over 300,000 units in 1914, cars have no longer been just an alternative to carriages, but also transcended transportation into a new era. However, the rapid popularity of cars also resulted in several unprecedented traffic problems, such as traffic congestion and traffic accidents. To investigate and resolve these traffic problems, how to correctly model macroscopic traffic flow behaviors or microscopic car following behaviors have become major research challenges for transportation researchers. Since the very first macroscopic traffic flow model proposed by Professor Bruce Douglas Greenshields in 1935, research pertaining to traffic flow theory has continued for almost 80 years. Since then, numerous traffic flow models have been proposed and validated, of which several analogously model traffic behaviors based on fluid dynamics have been introduced, and others focusing on microscopic driving behaviors were proposed. In Taiwan, numerous researchers have devoted themselves to the study of traffic flow theory and published numerous related papers. Unfortunately, no Chinese-based textbooks or monographs regarding traffic flow modeling have previously been published. To fill this gap, this monograph aims to introduce the mathematical concepts and insights of traffic flow modeling through a systematical overview and compilation of traffic flow literature, including several of our previous studies. The monograph contains three parts, in which the the first part (Chapter II) introduces macroscopic traffic flow models; the second part (Chapters III and IV) introduces microscopic car-following models; and the third part (Chapters V to VIII) elaborates continuum flow models, which includes simple continuum models and high-order models, as well as finite-difference approximation methods for these models. We hope that this monograph serves as a guideline for elementary researchers and as a reference for advanced researchers in traffic flow modeling. |
