THE OPTIMIZATION OF HORIZONTAL AND VERTICAL ALIGNMENT

The author defines road design in horizontal and vertical alignment, and describes the preliminary feasibility and final design stages. The main costs in road design (construction costs, vehicle-operating costs, design and administrative costs, maintenance costs and social costs) are listed and their modelling for computerized design is outlined. Constraints to be taken into account in road design: geometric design standards, phasing restrictions, level and passage controls are given together with several basic techniques which have been tried for optimizing road alignments. A brief description is given of programs used to optimize vertical and horizontal alignments in the USA, France, Denmark, Germany, United Kingdom (TRRL and University of London programs). For the covering abstract of the proceeding, see IRRD Abstract No. 212272. /TRRL/
