摘要
城市交通系统是个随机性很强、复杂的巨型系统,为了获得良好的通行效率,提出了一种基于模拟退火温度的自适应粒子群优化算法,同时给出了一种城市区域交通协调控制信号配时模型,然后将提出的方法应用于此模型。仿真结果表明:这种算法不仅能够克服基本粒子群算法陷入局部寻优的缺点,而且算法的收敛性和稳定性都很好,同时也表明该模型是可行的、有效的。
The city transportation system is a random and complicated giant system. To acquire good traffic efficiency, a new adaptive Particle Swarm Optimization (PSO) algorithm based on simulated annealing temperature (SATPSO) was proposed, and a new harmony control signal model of city transportation was given. Then SATPSO was used in the model. The emulation results show that the algorithm can overcome the defects of the original PSO sinking into the local optimal, and has good convergence and stability. The model is feasible and effective.
