一种基于海量GPS数据的分布式地图匹配系统的设计与实现

Design and Realization of a Distributed Map-matching System for Massive GPS Data

针对海量GPS数据的应用环境,设计并实现了一种分布式地图匹配系统.该系统包含调度器和匹配节点两类节点:调度器个数唯一,内含接收和调度两个模块,前者负责从外部多个GPS数据源不断的接收海量GPS数据并缓存至本地全局共享数据包池,后者负责定期从池中取出包数据分发给各个连接至调度器的匹配节点;匹配节点可有多个,负责从调度器接收GPS数据包并完成数据的地图匹配.实际应用表明,该系统能够很好的满足海量GPS数据的匹配要求,并且具有较强的适应性和可移植性.

This paper designs and realizes a distributed map-matching system for massive GPS data. In this system ,there are two kinds of nodes：dispatcher node and matching node. The dispatcher node receives massive GPS data from outer GPS data sources and periodically dispatches GPS data to the matching nodes,where the data is map-matched. An actual project shows,this system is well designed for massive GPS data and has strong adaptability and portability.
