碩士 === 國立中央大學 === 土木工程研究所 === 93 === Abstract Ramp metering control is one of the strategies to maintain traffic flows to satisfy a certain level of service in highway. However, the most ramp metering controls nowadays focus on single ramp and are pretimed without a concern of whole system. In the following study, we will formulate estimating multi-objective O-D matrices model based on user-equilibrium principle, the lowest travel time cost, and risk value to fit a certain level of service in highway. To make some progress to solve the problem, we suggest constructing a supernetwork and proceed with Frank-Wolfe method combining largrangian relaxation to do traffic assignment. Finally, we take resulting O-D data of numerical examples to be the basis of the further research of bi-level optimal dynamic ramp metering strategy problem.
