摘要
应用预测控制的机理,提出基于可校正交通流预测模型和两级遗传算法以实现交通分配和交通控制相结合的交通流系统计算机控制方法。基于伪给定、预测模型、滚动优化和反馈调节的交通流预测控制系统能够实现有性能保障的交通流系统控制,为交通拥堵预防和拥堵恢复畅通提供全局性的分析和决策支持。该系统通过综合集成应用现代信息处理技术、优化技术、专家系统、交通流及交通控制理论,为交通分配和交通控制的结合提供了工程实现途径。
Authors employed the mechanism of predictive control to present the approach of traffic flow system computer control to realize the combination of traffic assignment and control, based on the adjustable traffic flow predictive model and two-layer genetic algorithms. The system of traffic flow predictive control with pseudo set point, predictive model, moving optimization and feedback adjustment could realize performance assurance control of traffic flow system, which provides global analysis and decision-making support for the prevention and recovery of traffic congestion. The presented system of traffic flow predictive control provided the solution of engineering realization with the combination of traffic assignment and control through synthetic and integrated application of advanced information processing technique, optimization technique, expert system, traffic flow and traffic control theory.
