The book covers the planning and design of highways and country roads. The quality requirements for the road are derived from the network planning. After an excursus into the fundamentals of driving dynamics, the design elements are described in the site plan, in the height plan and in cross-section. After a detailed presentation of the intersection solutions, the necessary equipment is compiled. This book is a translation of the original German 1st edition Planung von Autobahnen und Landstraßen  by Richter Thomas published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2016. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
