Complex traffic conditions lead to excessive driving workload,further result in impaired driving performance.Therefore,it is meaningful to study the driving workload evaluation with driving performance.In this study,considering four road environmental factors,radius,slope grade,traffic flow and traffic sign information volume,the L16(45)orthogonal experiment was designed for simulated driving test.After simulated driving test,driving performance indicators,such as speed,THW,and SDLP in workload environment were analysed; meanwhile,the subjective driving workload was obtained through NASA-TLX scales analysed.The relationship between driving performance and subjective driving workload were quantitatively analyzed.The results indicated that,out of traditional performance indicators,the mean of THW has more significant correlation with subjective workload.The results contribute to workload assessment and traffic safety analysis.

为把握新开通城市轨道对交通出行的影响，对宁波轨道交通1 号线开展了乘客流量和出行调查。结果 显示，轨道交通沿线的部分常规公交和出租车客流显著减少，而轨道乘客中源自常规公交的比例最高。随着轨道新线路的开通，公共交通的出行量进一步向轨道方式集聚，常规公交和出租车客流持续走低，而小汽车出行则平稳发展。研究表明，宁波轨道交通与常规公交、出租汽车之间形成了无效竞争，而对小汽车出行替代有限，这限制了轨道交通缓

为了研究山地城市互通立交匝道在交通低密度的情况下大、小客车的车道使用行为情况，在重庆市主城区收集了车辆在各互通立交匝道路段车道使用行为的相关数据。运用人工判读的方法，对收集到的数据进行分析，总结出大、小客车在互通立交匝道路段车道使用行为的特点，并得出不同驾驶员的车道使用行为习惯。分析结果表明：1)小客车驾驶员倾向于使用内侧车道，且维持原车道行驶，不倾向于采取主动变道操作；2)大部分大客车驾驶员倾向
轮胎湿抓地性能是轮胎湿地安全性能的重要体现，也是欧盟认证中不可或缺的认证项目。测试环境及边界条件的界定，是轮胎湿抓地性能测试的重要保证。水膜温度、水膜厚度、轮胎负荷、轮胎气压、测试车辆、测试手段是影响轮胎湿抓地性能测试的主要因素。
本文基于700 份在线问卷调查为数据基础，结合实地访谈，总结分析共享单车的使用特征。基于因子分析，构建影响共享单车满意度的结构方程模型，结果显示："方便快捷"对满意度影响程度最大，"产品服务"其次，"成本付出"影响相对较小，"道路设施"很大程度上影响"方便快捷"，对满意度有间接影响。最后，提出对政府管理的意见和对策，希望改变"乱停乱放"的市容，提高共享单车满意度和使用效率，实现低碳环保出行方式，促
