The invention discloses a traffic event-oriented highway traffic control effect evaluation method, and belongs to the technical field of traffic management and control. The method comprises the stepsof: 1, collecting traffic event information, historical traffic operation information, road basic information and traffic management and control mode information; 2, discretizing time points, and collecting traffic data after an event occurs; 3, utilizing VISSIM software to predict evolution of the traffic operation state after the event occurs under the condition of no control, and calculating anevaluation index; 4, determining an event influence range under a control condition according to an improved input and output model, and calculating the evaluation index; 5, comparing the index difference to obtain an evaluation result; and 6, finally determining the weight of traffic facilities, and calculating the service level index of the traffic system. According to the method, the traffic control effect is completely evaluated through calculation of the lifting indexes of the facilities influenced by traffic control and calculation of the comprehensive traffic system indexes.
一种面向交通事件的高速公路交通管控效果评价方法,属于交通管理与控制技术领域。本发明包括步骤一.收集交通事件信息及历史交通运行信息、道路基础信息和交通管控方式信息;步骤二.离散化时间点,并采集事件发生后的交通数据;步骤三.利用VISSIM软件预测无管控条件下,事件发生后交通运行状态的演变,计算评价指标;步骤四.根据改进的输入输出模型确定有管控条件下事件影响范围,计算评价指标;步骤五.对比指标差距,得出评价结果;步骤六.最后确定交通设施权重,计算交通系统服务水平指标。本发明中通过对交通管控所影响的各设施的提升指标计算及综合交通系统指标计算,完整评价了交通管控效果。
