The invention belongs to the technical field of the
simulation and optimization of a
traffic system, and particularly relates to a multi-resolution modeling
simulation system and a multi-resolution modeling
simulation method for the
traffic system. The
system consists of a
macro / meso layer, a micro layer, an interaction
resolver, a consistency enforcer and a
shared attribute core module, wherein input ends and output ends of the
macro / meso layer and the micro layer are connected with the consistency enforcer respectively; the input ends of the
macro / meso layer and the micro layer are connected with the interaction
resolver; and the input end and the output end of the consistency enforcer is connected with an attribute core. When the
system begins to operate, the flow is loaded onto various sub-entities; when the flow enters another resolution layer from one resolution layer, an upstream entity sends an external event to a downstream entity, and the downstream entity can decide the sequence of responding to the external event according to the condition; the consistency enforcer is responsible for ensuring that the macro / meso layer and the micro layer can respond to the external event respectively and keep the consistency of system state; after the response, the consistency enforcer can still be responsible for the difference of response results of the macro / meso layer and the micro layer; and output flow, velocity and density information are taken as the external event which is output to the downstream entity. The system and the method solve the problem of the maintenance of system consistency in multi-resolution simulation, provide a basic method and realization components for converting
traffic simulation models with different resolutions, and further realize the macro, meso and micro multi-resolution simulation on the
traffic system.
