相位滚动 meaning in Chinese

phase roll

The construction graph of the ant colony optimization ( aco ) algorithm is revised to solve traffic control problems . and the aco algorithm is improved further to obtain better search efficiency in large - scale traffic control problems . finally , on the simulation and analysis system for urban mixed traffic ( sasumt ) that was developed by zhejiang university , the two utaccss are compared and analyzed in the cases of an isolated intersection , an arterial road and a traffic region
本文主要在这三个方面进行了深入研究，相应地建立了配时参数协调优化和信号相位滚动优化两种主要的基于模型的utaccs控制算法，通过设计蚁群优化( antcolonyoptimization ， aco )算法的解构造图使其能够应用于交通控制问题的求解，并且改进aco算法以提高其在大规模交通控制问题上的搜索性能，最后在浙江大学自主研发的城域混合交通仿真与分析系统( simulationandanalysissystemforurbanmixedtraffic ， sasumt )上从单点控制、干线控制及区域控制不同层次对所建立的两种控制算法的控制效果进行了比较和分析。
