Originally published in 1987, this title reviews and evaluates the methodologies suitable for highway evaluation, along with the UK transport supplementary grant and TPP (Transport Policies and Programme) system. Examples of current UK practice are briefly described, with more details being given of the technique of priority ranking used in the case study area of the West Midlands. Multi criteria approaches are reviewed in chapter two. Chapter three looks at the choice of highway data input in the light of those available, and the practical structure of factorial analysis applied to the case study area. The book covers following issues: computer structure and requirements; highway problem data; referencing methods; site definition; and weighting methods. The results from this study are described and then analysed by classical factorial analysis. The implications of the technique for the TPP preparation process, for the derivation of priorities, and the highway evaluation process as a whole are given. Specific techniques, such as factorial analysis, bridge problem and bus aid ranking, highway capacity calculations and sensitivity testing, as well as the computer programs used (March and COBA) are described in greater detail in the appendices.
