AN EQUIVALENT OPTIMIZATION PROBLEM FOR COMBINED MULTICLASS DISTRIBUTION, ASSIGNMENT AND MODAL SPLIT WHICH OBVIATES SYMMETRY RESTRICTIONS

This paper presents a model for combined multiclass trip distribution, trip assignment and modal split. Although this model is based on an equivalent optimization problem, it avoids the symmetry restrictions heretofore always associated with such approaches to multiclass trip assignment. This is accomplished by expressing Wardrop's first principle as a set of nonlinear constraints in standard mathematical programming form. An algorithm is proposed, each iteration of which requires solving a nonlinear program with linear constraints.(a) (TRRL)
