Abstract
This study develops a DSO (Dynamic System Optimum) simulation algorithm first, which can reproduce the traffic condition so as to minimize total travel time on condition that time-dependent OD demand is given. Next, the algorithm is verified by applying to a simple network with one OD pair. Recently most of dynamic traffic simulation models reproduce traffic flows dynamically under the principle of DUO (Dynamic User Optimal). On the other hand, DSO solution must provide practical information for the effective traffic control such as ramp metering control and road pricing measure. However, there is no simulation algorithm seeking for the DSO solution Therefore, in this study, DSO simulation algorithm has been developed in accordance with Dynamic Marginal Cost equilibrium principle, which equilibrates DMC of all routes. As a result of the verification, it has been confirmed that the proposed model and algorithm efficiently solved DSO solution.
