Description
This reference book communicates the basic theoretical knowledge, the practical requirements and experience for designing, mapping, calculating and checking roads and the planning process overall - and at the same time reveals important development trends. The book is guided by the current rules and regulations in Germany, it universalizes this knowledge and also integrates important current research results in road design processes. In order to restrict the scope of the book, it only deals with the theoretical principles and knowledge, and the practical experience for designing rural roads, i.e. the special features of urban roads are not mentioned here. This clear separation primarily results from the different principles and rules and regulations. The terms, definitions, abbreviations and formula symbols are based on German usage, but can be transferred to an international framework without any difficulties. The work is particularly designed to be a course book for students of road design. As a reference book, it supports the ongoing training process for road transportation engineers in planning offices and public bodies.Any specialist working in the transportation sector can use it as a reference book.
