利用信息学与控制相关理论对道路交通安全设施进行研究,建立了交通管理的过程控制模型,分析了当前道路交通安全设施常规设计方法在机理上存在的不足,提出了一种自顶向下的、层次清晰的,支持交通安全设施的系统性设计,使交通安全设施设计的设计结果具有可评价性和可校正性的道路交通安全设施设计流程,并对整个流程的具体构造进行了详细地分析。 Based on the theory of information science and control, this paper studies the road traffic safety facilities, establishes the traffic control process control model, analyzes the shortcomings of the conventional road traffic safety facilities routine design methods, and proposes a top-down , A clear level of support for the systematic design of traffic safety facilities, road traffic safety facilities design flow that makes the design results of traffic safety facilities design evaluable and correctable, and analyzed the detailed construction of the whole process in detail .
