碩士 / 國立臺灣大學 / 土木工程學研究所 / 88 / We develop a congestion pricing model for a transportation corridor based on the optimal control theory. With the optimality conditions for this model, we use the economic meanings of the multipliers of the optimal control problem to define the marginal cost involved by vehicles into the system. These multipliers help us to derive the externality and to develop the toll pattern. The O-D trips in the network are determined by the generalized costs of the O-D pairs in equilibrium. Travel time cost function and schedule delay cost function are used to show the difference between the peak and off-peak periods. The optimality conditions are derived and applied to analyze the externality and to define the toll pattern. Under the objective of maximum social welfare, it is shown that a system optimal flow pattern can be reached through imposing a toll which equals the difference between the social cost and the private cost. A simplified case is shown to compare this model with other assignment model. We develop a solution algorithm to decompose the dynamic problem into many time periods and use two examples to test the validity of the algorithm.
