Subnetwork Origin-Destination Matrix Estimation under Traffic Demand Constraints

This paper proposes a subnetwork origin-destination (OD) matrix estimation model under traffic demand constraints (SME-DC) that explicitly considers both internal-external subnetwork connection and OD demand consistency between the subnetwork and full network. This new model uses maximum entropy of OD demands as the objective function, and uses total traffic generations (attractions) along with some fixed OD demands for each subnetwork OD node as the constraints. The total traffic generations and attractions along with the fixed OD demands for subnetwork OD nodes are obtained through OD nodes transformation and subnetwork topology analysis. For solving the proposed model, a convex combination method is used to convert nonlinear SME-DC to classical linear transportation problem, and tabular method is used to solve the transportation problem. The Sioux Falls network and Kunshan network are provided to illustrate the essential ideas of the proposed model and the applicability of the proposed solution algorithm.
