The Utility of Utility Theory in Regional Transportation Mix Analysis.
Methods for applying utility theory to measure benefits of alternative regional transportation mixes, as part of a comprehensive evaluation. The base case is always the continuation of present trends. Interest groups are defined--users, operators, other social groups affected, implementing and regulatory agencies, lobbying groups. The attributes desired by each are specified, excluding those that are infeasible or unacceptable. Ways are presented for measuring them and for aggregating over lower-level attributes to find summary utility measures. A range of methods is proposed for overall comparison: qualitative evaluation; ordinal scaling arranged so the preferred value is always at the right; direct assignment of worth scores; construction of worth functions for each attribute; weighting on some policy basis--e.g., regarding importance to influential groups or to the disadvantaged. The worth functions and weighting methods may be either deterministic or probabilistic. (Prepared for the 36th national ORSA meeting, November 1969.) 21 pp. Ref.
