碩士 / 國立臺灣海洋大學 / 河海工程學系 / 92 / This paper considers that the demand of private vehicle is increasing each year, especially in the peak-hour, commuters frequently confront congestion at corridors connecting CBD and satellite cities. The government wants to shift commuters from private vehicle to the mass transport system. But commuters choices the vehicle, they only travel by the vehicle that is best utility as such. Once mass transport system doesn’t have enough attractive power to the commuters that the government can’t increase the utility rate of mass transport. So the government may adopt transportation system management (TSM) to shift commuters reasonably. The TSM is either increase the limited of private vehicle or construct the perfect mass transit system.
Because a conflict between government and commuters, this paper will set up optimal mode-mix model upon the bilevel programming. The higher level is transportation authority whose purpose is minimum transportation social cost; the lower level is many commuters whose purpose is minimum disutility. And this paper use multinomial logit model (MNL) to the mode-mix modal of lower level. Then analyze the interactive relationship between transportation authority and many commuters of each TSM strategies under three limits, energy environment and economics. Finally, we hope to find out the optimal dispensable rate that giving consideration to two levels.
We can find the hierarchical relationship between government and commuters, they have stackelberg model. In the process of solving the lower level equilibrium solution, there is having Nash Equilibrium model. In this paper, we set up a heuristic algorithm to make solution. And in the case study, we provide four TSM strategies that transportation authority may take effect to make sensitivity analysis. It proves the feasibility of this study’s bilevel optimal mode-mix model.
According to the previously describes analysis, the modal of this paper can express the corresponding dispensable rate under limited of each TSM strategies. The heuristic algorithm not only can solve the bilevel modal, but also can get the solution of Nash Equilibrium. At end, we adduce this paper have well extension and put forward future research direction for reference.
