文章基于微观交通仿真软件Paramics,提出针对干线协调控制优化模型控制效果的比较评价思路以及较全面的评价指标。以典型城市干线为仿真实例,从干线控制效果及全路网控制效果两方面,选取6个评价指标,对比分析了三个不同优化模型的控制效果。结果表明,基于Paramics的干线协调控制模型效果评价思路有效可行;实例中三个模型都有不同程度的优化;TRANSYT模型明显减小路网总延误;MAXBAND模型提高干线车流行驶连续性;三者中TRANSYT-MAXBAND结合模型最优,可在减小路网延误的前提下,提供较大的主干道双向绿波带宽。
Based on the micro-traffic simulation software Paramics, this paper proposes a comparative evaluation idea and a more comprehensive evaluation index for the control effect of trunk line coordination control optimization model. Taking the typical urban trunk line as an example, six evaluation indexes are selected from the control effects of the main line and the control effects of the whole road network, and the control effects of the three different optimization models are compared and analyzed. The results show that the Paramics-based trunk line coordination control model is effective and feasible; the three models in the example have different degrees of optimization; the TRANSYT model significantly reduces the total delay of the road network; the MAXBAND model improves the continuity of the main line traffic flow; TRANSYT-MAXBAND optimal combination of models, can reduce the road network delay under the premise of providing a larger main road two-way green bandwidth.
