Numerical analysis for adaptive traffic simulation

Because of the increased interest in modeling multiresolution traffic simulation, the adaptive simulation concept and approach are addressed. Adaptive simulation does not predefine the spatial-temporal domain of high-fidelity simulation rules, but rather uses driving conditions and driver response. Adaptive simulation is intended not to couple two or more simulation models of known resolution but to create a finer scale of resolution with a range of rules to allow smoother transition in the spatial-temporal resolution domain. The adaptive simulation concept is implemented in the anisotropic mesoscopic simulation framework, in which a lane-based simulation framework and lane-changing rules, as well as a triggering mechanism, are devised. The numerical experiments highlight the difference between hybrid and adaptive simulation. The general property, such as sensitivity of the adaptive simulation model with respect to its parameter, is also tested, and its performance reported.
