Network representations of performance analysis parameters and relationships are described. In these models, nodes represent variables or other information and links represent relationships. The intersection performance analysis procedures implicit in the highway capacity manual are formalized as an example of a network representation. These representations make use of semantic net and frame representations originally developed in the field of artificial intelligence.The purposes of network representations of analysis procedures are (1) to aid flexible, computerbased implementations; (2) to facilitate interpretation of results; and (3) to provide a check on the completeness and uniqueness of particular analysis procedures. For computer-aided analysis and design, these representations provide a meansto provide localized or variable specific representation of "intelligent" solution schemes.
