The invention relates to the technical field of traffic, in particular to a signal intersection operation evaluation method in a mixed traffic environment based on an entropy theory. The method comprises the following steps: S1, selecting evaluation indexes according to mixed traffic characteristics, and constructing a signal intersection evaluation index system in a mixed traffic environment; s2, dividing the indexes into positive indexes and negative indexes according to the influence of the evaluation indexes on traffic operation; according to the signal intersection operation evaluation method in the mixed traffic environment based on the entropy theory provided by the invention, the stop line is taken as a boundary, the intersection is divided into the interior and the exterior, the mixed traffic characteristics and the existing mixed form of the signal intersection are fully described and analyzed, and the signal intersection operation evaluation method in the mixed traffic environment based on the entropy theory is realized from the aspects of traffic operation safety and efficiency. A mixed traffic environment characteristic index evaluation system which can better reflect the actual traffic operation state is established, and the accuracy of the model is effectively improved.
本发明涉及交通技术领域,尤其涉及一种基于熵理论的混合交通环境下信号交叉口运行评价方法。步骤如下:S1:根据混合交通特性,选取评价指标,构建混合交通环境下信号交叉口评价指标体系;S2:根据评价指标对交通运行产生的影响,将指标分为正向指标与负向指标。本发明提供的一种基于熵理论的混合交通环境下信号交叉口运行评价方法,通过以停车线为界,将交叉口划分为内部和外部,充分描述和分析信号交叉口存在的混合交通特性,已经存在混合形式,并从交通运行的安全性和效率角度出发,建立了更能反映实际交通运行状态的混合交通环境特征指标评价体系,有效提高了模型的准确性。
