It constructs shared parallel data-structure of traffic network simulation based on standard template library function, and uses SQL database technology to access parallel data-structure so that it can reduce occupation of memory resource. Each simulation unit can conveniently access network data. 根据标准模板库函数建立交通网络仿真的共享并行数据结构,并利用SQL数据库技术进行并行数据结构的存取,以减少对内存资源的占用,方便各仿真单元对网络数据的同步访问。
