Informationen zum Autor Martin Rogers BE, MEngSc, PhD, BA(Public Ad), CEng, MICE, MRTPI, Chartered Engineer and Chartered Town Planner, has worked in private practice as well as in local authorities, and was a member of the Dublin Transport Initiative Study Team that devised the first integrated transportation plan for the Dublin city region. He joined the permanent staff at the Dublin Institute of Technology in 1993, was Assistant Head of School with responsibility for first year engineering from 2010 to 2014, and is currently a Senior Lecturer in the School of Civil and Structural Engineering. Bernard Enright BE, MSc, PhD originally qualified as a civil engineer and worked in information technology in engineering and in the financial markets for 25 years. He joined the School of Civil and Structural Engineering at Dublin Institute of Technology as a Lecturer in Civil Engineering in 2003, where he chairs the Bachelor of Engineering Technology degree programme in Civil Engineering. He completed his PhD on the subject of traffic loading of highway bridges in 2010, and has published extensively on this and related topics. Klappentext The repair, renovation and replacement of highway infrastructure, along with the provision of new highways, is a core element of civil engineering, so this book covers basic theory and practice in sufficient depth to provide a solid grounding to students of civil engineering and trainee practitioners.* Moves in a logical sequence from the planning and economic justification for a highway, through the geometric design and traffic analysis of highway links and intersections, to the design and maintenance of both flexible and rigid pavements* Covers geometric alignment of highways, junction and pavement design, structural design and pavement maintenance* Includes detailed discussions of traffic analysis and the economic appraisal of projects* Makes frequent reference to the Department of Transport's Design Manual for Roads and Bridges* Places the provision of roads and motorways in context by introducing the economic, political, social and administrative dimensions of the subject Zusammenfassung The repair, renovation and replacement of highway infrastructure, along with the provision of new highways, is a core element of civil engineering, so this book covers basic theory and practice in sufficient depth to provide a solid grounding to students of civil engineering and trainee practitioners.* Moves in a logical sequence from the planning and economic justification for a highway, through the geometric design and traffic analysis of highway links and intersections, to the design and maintenance of both flexible and rigid pavements* Covers geometric alignment of highways, junction and pavement design, structural design and pavement maintenance* Includes detailed discussions of traffic analysis and the economic appraisal of projects* Makes frequent reference to the Department of Transport's Design Manual for Roads and Bridges* Places the provision of roads and motorways in context by introducing the economic, political, social and administrative dimensions of the subject Inhaltsverzeichnis Preface xii Sources xiv 1 The Transportation Planning Process 1 1.1 Why are highways so important? 1 1.2 The administration of highway schemes 1 1.3 Sources of funding 2 1.4 Highway planning 3 1.5 The decision making process in highway and transport planning 9 1.6 Summary 14 1.7 References 15 2 Forecasting Future Traffic Flows 16 2.1 Basic principles of traffic demand analysis 16 2.2 Demand modelling 17 2.3 Land use models 19 2.4 Trip generation 20 2.5 Trip distribution 24 2.6 Modal split 35 2.7 Traffic assignment 40 2.8 A full example of the four stage transportation modelling process 46 2.9 Concluding comments 52
