将粒计算技术引入到元胞自动机的交通流研究中,从而为进一步提出基于元胞、粒和交通网络三层结构的交通流系统奠定基础,继而改进传统交通流模拟系统的架构.在此交通流模拟系统中,粒及粒计算的思想反映为系统设计中的车队概念,而在某一时间步进内,交通网络中所有车辆的更新将按照路段、车队、车辆的层级顺序进行.“,”Granular computing technology is introduced into the cellular automata traffic flow study. Based on the three-layer construction of cells, granules and traffic network, the traditional traffic flow systems may be improved. For the new traffic flow simulation system, the idea of granules and granular computing is reflected in the concept of motorcade, and the status of all cars will be updated in the hierarchal order of road sections, motorcades and vehicles during a time step.
