Abstract

This note shows how the maximum entropy trip matrix estimation procedure incorporated in ME2 as proposed by Willumsen (Van Zuylen and Willumsen, 1980) can be combined with a user optimal assignment model such as SATURN (Van Vliet, 1982) into a single mathematical problem. The resulting problem has the form of a bilevel programming problem similar to matrix estimation methods proposed by Nguyen (1981). The mathematical framework for the user optimal assignment problem is summarized, followed by a description of the maximum entropy trip matrix estimation procedure proposed by Willumsen. The two models are then combined into a single problem and a discussion follows on solution procedures.
