J <br /> <br />Preface <br /> <br />I ~ ~ ~ Transportation and Land Development unites transportation and land use in an exciting <br />and timely discussion of the planning and design of circulation systems from the standpoint <br />of site development. In transportation, the design goal is to provide for the movement of <br />people and goods between and among land uses; In land development, the design goal is <br />to achieve a functiqna1 and profitable project. These goals at all times are highly inter- / <br />dependent and sometimes are in conflict. /' <br />The underlying assumption throughout this book is that the processes of trans- <br />portation and land development are inextricably bound: land development cannot occur <br />without transportation; transportation facilities selVe no economic purpose without devel- <br />opment. The text is organized on the basis that good planning precedes good design. <br />, Part I deals with the planning process inherent to both transportation and land <br />development. The text moves from a discussion of general planning principles to a <br />discussion of transportation and site planning principles, and fmally, to the pomt at which <br />the two processes meet in the site traffic analysis. ' <br />Part n deals with specific design considerations of transportation and land devel- <br />opment. The organization of Chapters 4,5, and 6 divides this highly related material to <br />group topics logically within each chapter while maintaining chapters which are of some- <br />what similar size. Chapter 4 discusses hierarchical movement systems - the basis. of <br />functional 'design criteria, which are equally applicable to public streets and private <br />developments. It also offers information on traffic-circulation considerations in residential <br />development. This discussion is directed toward traffic issues which have broad impli- <br />cations; it does not attempt to deal with the details of subdivision design. <br />Drive-in facilities present unique traffic-circulation problems and have been the <br />object of specific data collection. Also, drive-thm operations can be subjected to quan- <br />titative analysis. Chapter 8 therefore deals expressly with the parking and circulation <br />issues involved with this type of development. <br /> <br />I <br />I <br />l <br />I <br />I <br />~ <br /> <br />xl <br />
