| Outline of Final Research Achievements |
This study clarifies the relationship between a Macroscopic Fundamental Diagram (MFD) and congestion patterns on a general networks with one-to-many/many-to-one OD pairs. Specifically, we formulate a new inverse problem of the dynamic user equilibrium assignment problem for a give congestion pattern. The proposed problem is formulated as a system of linear equations; by solving this, we can derive analytical formula of a network throughput consistent with the congestion pattern. Thorough a sensitivity analysis of this formula, we identified the types of congestion patterns that cause the decreasing of a network throughput (i.e., the mechanism of a decreasing branch of MFDs).
