Infrastructure Research and Multi-Resolution Modeling of Cooperative Vehicle-Infrastructure System

Abstract

A multi-resolution simulation of the cooperative vehicle-infrastructure system is of great significance for traffic-simulation research. An HLA-based framework and simulation models for the cooperative vehicle-infrastructure system are constructed. The HLA/RTI management mechanism can realize transparent data transmission and shield the tedious details of the underlying information interaction. Then this paper focuses on multi-resolution modeling (MRM) of the cooperative vehicle-infrastructure system and analyzes in detail aggregation and disaggregation theory as well as assistance in the MRM. Different MRM methods that apply to subsystems in the train control system are considered in accordance with hierarchical concerns and features of the cooperative vehicle-infrastructure system as being multi-node and distributed.
