Description
Summary:碩士 === 國立交通大學 === 運輸與物流管理學系 === 102 === The core of this study is to design an offset by constructing and solving a multi-based arterial signal control optimization model. Existing models for arterial signal control focusing on maximizing the progression for two-way through traffic flows cannot adequately account for some heavy-path flows that need to take multi turning movements along the arterial. In this paper we present a new optimization model for more than two paths needed to be considered about progression. The proposed model is a direct extension of MAXBAND under a predetermined phasing plan. The phase sequence, green split and cycle time which are fixed is our assumption. Our objective function is to maximize the multi-path green bands. We build a mixed integer linear programming (MILP) model for an offset design for solving this kind of problem. In addition, we extend the model by adding the multi-band on each intersection and this ideal comes from Gartner. The algorithm we used is branch-and-bound. The results of extensive numerical investigation with field data are used to analysis the performance of our offset design. In a few word, this study developed a math model for an offset design for multi-path based arterial signal control optimization model which has a better performances on the critical paths.
