Development of Dynamic Micro- and Macroscopic Hybrid Model for Efficient Highway Traffic Simulation

This paper presents a dynamic hybrid traffic simulation model and its improvement. Here, a hybrid traffic simulation model is defined as a combination of multiple traffic models with different resolutions, which are dynamically switched to each other. The proposed model couples a microscopic and a macroscopic model. In a dynamic hybrid model, the application domains of micro- and macroscopic models can be switched during the simulation to achieve overall speed-up while keeping a high resolution of the area of interest. The authors extended an existing dynamic hybrid model to be applicable to highway merging sections. The proposed model was also validated by data obtained on an actual highway.
