Description
Summary:碩士 === 國立交通大學 === 運輸科技與管理學系 === 93 === The purpose of this research is to develop a new dynamic macroscopic model. In this research, we introduce the traffic fields and mobility into this new model. The traffic field is subdivided into external field and internal field, the external field is caused by the external conditions in the roads and the internal field is caused by the interactions between the adjacent cars. We assume that all cars move fast or slowly according to the magnitude of traffic field. Mobility is a key factor to affect the behaviors of vehicles and the thresholds of traffic fields. We design a microscopic model first and calibrate the model by the result of our simulator. The simulator is designed based on CA model. We define the magnitude of acceleration and deceleration in the simulator according to Monte Carlo computing technique. After that, we derive the macroscopic model from the microscopic one. It is the reason that every variables and parameters in this research are meaningful. Besides, we define a new variable, Driver’s inertia, to describe the shock caused by the lane-changing behaviors.
