In this paper, we present our system MRQSim to efficiently conduct the continuous range query in the simulated road network environment when the query object moves. We propose two kinds of query types and consider complex simulation setups. The relative system architecture and demonstration are illustrated. Because incremental maintenance methods based on valid intervals are adopted and the potential uncertainty of objects is considered, MRQSim can obtain high efficiency with good adaptability to complex running scenarios.
