Available in PDF, EPUB and Kindle. Book excerpt: Creating Traffic Models is a challenging task because some of their interactions and system components are difficult to adequately express in a mathematical form. Traffic Flow Theory: Characteristics, Experimental Methods, and Numerical Techniques provide traffic engineers with the necessary methods and techniques for mathematically representing traffic flow. The book begins with a rigorous but easy to understand exposition of traffic flow characteristics including Intelligent Transportation Systems (ITS) and traffic sensing technologies. Includes worked out examples and cases to illustrate concepts, models, and theories Provides modeling and analytical procedures for supporting different aspects of traffic analyses for supporting different flow models Carefully explains the dynamics of traffic flow over time and space

Available in PDF, EPUB and Kindle. Book excerpt: To serve research needs for traffic flow model development and highway safety enhancement, we model interactions between human factors and traffic flow character- istics, this topic includes methods on collecting data, modeling impacts of parameters on flow, and calibrating parameters on observed data. An example of successful traf- fic data collection is NGSIM data, which contains location, speed, and acceleration information of vehicles. An algorithm was designed to match and extract vehicles' trajectory records, and utilize the extracted information for pattern recognition of lane changing maneuvers. This algorithm reads records from an NGSIM data set, pick out vehicles executing lane changing maneuvers, and note the corresponding time stamps. Also through matching these records by vehicle ID and time stamp, we obtain a map of vehicles when a lane changing is happening, thus calculating gaps and relative speeds becomes possible. An example of utilizing these information is pattern recognition on lane changing maneuvers. We analyze lane changing maneu- vers with speed data and gap data. The approach with speed data shows convincing results, as most lane changing vehicles have a descending and then ascending pattern on their speed profiles before executing the maneuver. On the other hand we can use collected data for calibrating parameters in traffic flow models. A heuristic method- ology is implemented to provide results with high accuracy, high efficiency and high robustness. Techniques include data aggregation and bisection analysis are applied in this approach to ensure achieving these goals and further requirements. Two traf- fic flow simulation models, Longitudinal Control Model (LCM) and Newell's Model are calibrated by applying this approach using traffic data collected at Georgia 400 highway in July, 2003, with satisfying accuracy and robustness produced in a running time of less than 2 seconds. Meanwhile we can enhance human factors by applying new technologies, and connected vehicle is a good example which is rapidly devel- oping. Future vehicles will be able to communicate with each other which greatly improves drivers' situational awareness. Consequently, drivers may be able to re- spond earlier to safety hazards before they manifest themselves in forms of imminent danger. Therefore, the overall effect of this technology can be attributed to drivers' enhanced perception-reaction (P-R) capability which, in turn, translates to improved flow and capacity. However, it is critical to quantify such benefits before large-scale investment is made. In our research, a statistical transformation model is formulated to predict the probability distribution function of flow. By entering distributions of P-R time and enhanced P-R time, this model helps compare before and after distri- butions of traffic flow, based on which benefits of connected vehicles on traffic flow can be analyzed.

This book was released on 2009-09-16 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding of empirical traf?c congestion occurring on unsignalized mul- lane highways and freeways is a key for effective traf?c management, control, or- nization, and other applications of transportation engineering. However, the traf?c ?ow theories and models that dominate up to now in transportation research journals and teaching programs of most universities cannot explain either traf?c breakdown or most features of the resulting congested patterns. These theories are also the - sis of most dynamic traf?c assignment models and freeway traf?c control methods, which therefore are not consistent with features of real traf?c. For this reason, the author introduced an alternative traf?c ?ow theory called three-phase traf?c theory, which can predict and explain the empirical spatiot- poral features of traf?c breakdown and the resulting traf?c congestion. A previous book “The Physics of Traf?c” (Springer, Berlin, 2004) presented a discussion of the empirical spatiotemporal features of congested traf?c patterns and of three-phase traf?c theory as well as their engineering applications. Rather than a comprehensive analysis of empirical and theoretical results in the ?eld, the present book includes no more empirical and theoretical results than are necessary for the understanding of vehicular traf?c on unsignalized multi-lane roads. The main objectives of the book are to present an “elementary” traf?c ?ow theory and control methods as well as to show links between three-phase traf?c t- ory and earlier traf?c ?ow theories. The need for such a book follows from many commentsofcolleaguesmadeafterpublicationofthebook“ThePhysicsofTraf?c”.
