摘　　要：对于尚未设置CAV专用道的路段,交通规划设计者亟需一种简单、高效的方法,用以快速分析在复杂的交通条件下CAV专用道规划方案的合理性。为此,首先,考虑异质车辆在纵向车道的空间分布与CAV在混合交通流中的比例,推导出不同类型车道通行能力计算公式,为后续车辆通行时间计算奠定基础;其次,基于用户均衡理论分析不同出行者在不同类型车道上的流量分布,据此计算不同类型车道的车辆出行时间成本;最后,从交通规划设计者的角度出发,针对混合使用和完全分离这两种不同的CAV专用道使用规则,通过比较设置CAV专用道前后车辆总的出行时间成本,提出CAV专用道规划方案合理性评估标准。结果显示,基于给定的CAV在混合交通流中的比例和路段的车道数,利用该评估标准可以快速判断拟采用的CAV专用道规划方案的合理性。For traffic planners,there is an urgent need for a simple and efficient method to quickly analyze the rationality of planning schemes under complex traffic conditions when facing the road sections where dedicated CAV lanes have not yet been deployed.Therefore,firstly,considering the spatial distribution of heterogeneous vehicles on longitudinal lanes and the proportion of CAV in the mixed traffic flow,different types of lane capacity calculation formulas were derived,laying the foundation for subsequent vehicle travel time calculations.Secondly,based on the user equilibrium theory,the traffic time distribution of different travelers on different types of lanes was analyzed,and the vehicle travel costs for different types of lanes were calculated accordingly.Finally,from the perspective of traffic planners,the rationality evaluation criteria for dedicated CAV lane planning schemes were proposed by comparing the total travel time costs of vehicles before and after setting up dedicated CAV lanes,targeting the two different rules of mixed use and complete separation of dedicated CAV lane usage.Based on the given proportion of CAV in mixed traffic flow and the number of lanes on the road section,the rationality of the proposed dedicated CAV lane planning scheme can be quickly judged by using the proposed evaluation criteria.
