【Abstract】 Real-time traffic signal Optimal Control problem has been discussed.Under the existed conditions of traffic facilities,this paper sets up nonlinear optimization models with linear constraining conditions and gave CLY series algorithms to solve the models.The focus of this paper is point-control problem.This passage firstly builds a corresponding model,and then designs the CLY-Point1 algorithm to solve it.In addition,this paper builds multi-storey optimization models to solve the line-control and area-control problems,and CLY-Point2,CLY-Line,CLY-Area algorithms are designed to solve these models.The results of numerical simulation show that CLY series algorithm are effective for the traffic real-time Optimal Control problem and shorten the average waiting time about 20% comparing with the fixed-time program.更多还原
