摘　　要：为研究驾驶员对潮汐车道使用意愿的影响因素,使用潜类别Logit模型探寻潮汐车道使用意愿中未观测到的异质性。通过问卷调查量表获得驾驶员对设置潮汐车道的心理潜变量因素,运用结构方程模型量化心理潜变量。对比分析只考虑个人属性和加入潜变量的潜类别Logit模型的拟合效果及异质性效应,进行平均边际效应分析。结果表明:加入潜变量的潜类别Logit模型拟合效果和异质性效应表现更优。潜类别Logit模型可将数据分为3类,分别占比11.2%、11.5%和77.3%。拥有1辆小汽车、驾龄5年以上和感知风险表现出显著的异质性。心理潜变量中,感知风险对选择愿意使用潮汐车道有显著负向影响,行为态度和社会影响对选择愿意使用潮汐车道有显著正向影响。Using tidal lanes is an effective traffic organization method to solve tidal traffic congestion.It is of great significance to study the influencing factors of tidal lane usage intention.The researches on tidal lanes mainly focus on the theoretical innovation of its setting mode,the investigation and analysis of its implementation effect,traffic safety and other aspects,while the researches on the intention of using tidal lanes from personal and psychological levels are few.In order to study the influencing factors of drivers’willingness,the latent class Logit model is used to explore the unobserved heterogeneity in the willingness.The psychological latent variables of the drivers’tidal lane setting are obtained through questionnaires,and a structural equation model is used to quantify the psychological latent variables.The thesis compares and analyzes the fitting effect and heterogeneity effect of the latent class Logit model considering only personal attributes and added latent variables.Then,an average marginal effect analysis is performed.First of all,the basic principle of the model construction is expounded.Secondly,this paper designs a questionnaire,obtains data through the questionnaire survey,and conducts descriptive statistical analysis and data tests.Thirdly,the significantly influencing factors are screened,and the fitting effect and heterogeneity effect of the latent Logit model,which only considers personal attributes and added latent variables,are compared and analyzed.Parameter estimation and average marginal effect analysis are then carried out to provide reference for improving the efficiency of tidal lane use.The results show that:(1)Data are obtained from personal attributes,psychological latent variable attributes and scene hypothesis attributes,and insignificant factors are eliminated.The latent Logit model with added psychological latent variables screens out the variables such as an age of 18-29 years old,those who are below a college degree,those who have children,those who own a car,
