UNDERSTANDING TRAFFIC SYSTEMS: DATA, ANALYSIS AND PRESENTATION

The aim of this book is to introduce and demonstrate techniques that the analyst, engineer or planner can apply in examining and solving traffic problems. The book is arranged in four parts. Part A, Introduction, introduces the theme "how to gain information and understanding about traffic systems through the derivation of traffic information from traffic data, and then how to apply this information in the assessment of the performance of traffic systems and their interaction with land use activities". The importance of traffic safety, traffic congestion, and the environmental impacts of traffic operations is emphasized and the role of analyses at various levels of detail is outlined. The technical endeavor of traffic impact analysis is then placed in the context of public decision making and current policy concerns. The relationship between traffic analysts and decision makers is discussed and the importance of the means by which traffic information and forecasts are presented to decision makers and the community is emphasized. The concepts of "what-if" analysis through computer modelling are introduced, leading to consideration of "pro-active" analysis that anticipates future problems and proposes solutions before the problems can emerge. Part B, Basic Traffic Theory, introduces the key theories relating to the operation of traffic systems. These range from the simplest theories concerning the behavior of traffic on isolated links (uninterrupted flow models), through theories relevant to the performance of junctions (interrupted flow models), and on to models dealing with the performance of complete networks. The use of traffic flow and transport network theory requires the acquisition and application of traffic data. Part C, Data Collection, describes the principles of good survey planning and management, stressing that data collection should only be undertaken after careful analysis of the problem to be investigated, definition of specific data needs, and the determination of resources available for data collection and analysis. The principles of experimental design and survey sample design are then introduced. A variety of methods for observing and estimating traffic parameters such as flows, speeds, queue lengths, parking needs, and patterns of demand are then described in detail. Part D, Data Analysis and Modelling, is concerned with the development and use of analytical techniques for transforming raw data into useful information.
