The invention relates to the field of traffic intelligent control, in particular to a variable speed limit strategy test method considering driver compliance in mixed traffic flow, which comprises the following steps: building a traffic scene, and setting the mixed traffic flow composed of HDV and CAV and having different CAV permeability; a VSL strategy is established, and the speed limit value of the upstream of the bottleneck area is calculated in combination with the CAV permeability; an HDV compliance degree is established, and the types of the drivers and the proportions of the different types of drivers are determined in combination with the speed limit value; and obtaining index data reflecting the traffic capacity according to calculation. According to the invention, a mixed traffic flow scene of intelligent network connection vehicle permeability is established, and reality data is analyzed to determine four compliance scenes and proportions of defensive drivers and aggressive drivers in different speed limit values in the corresponding compliance scenes; therefore, the speed limit value determined according to the speed limit strategy issued for the intelligent network connection vehicle and the traditional driver driving is closer to the real traffic scene, and the test effect of the variable speed limit strategy has more practical significance.
本发明涉及交通智能控制领域,尤其涉及一种混合交通流中考虑驾驶员服从度的可变限速策略测试方法,包括以下步骤:搭建交通场景,设置由HDV和CAV组成的不同CAV渗透率的混合交通流;建立VSL策略,结合CAV渗透率计算瓶颈区上游的限速值;建立HDV服从度,结合限速值确定驾驶员的类型以及不同类型驾驶员所占的比例;根据计算获得反应通行能力的指标数据。本发明通过搭建智能网联车渗透率的混合交通流场景,并通过分析现实数据确定了四种服从度场景及相应服从度场景下面对不同限速值时防御型驾驶员与攻击型驾驶员所占的比例,以此对智能网联车和传统人驾车发布限速策略确定的限速值,更接近真实的交通场景,对于可变限速策略的测试效果更具实际意义。
