摘　　要：交通相关学科的交叉性日益增多。以中国知网和万方数据库中近20年交通相关学科的硕博学位论文为数据源,对交通相关学科的研究生学位论文进行主题挖掘并对比热点主题变化趋势的异同,结果表明:①交通相关学科研究生学位论文的主要研究对象为陆路交通且最多关注的研究主题为列车运行组织,对航空交通的研究较少。②整体而言,交通相关学科硕士学位论文中列车运行组织、交通流预测等4个主题增长明显,交通运输政策、交通项目管理等4个主题下降明显;博士学位论文中列车运行组织、目标检测等4个主题增长明显,物流系统优化、交叉口评估等主题下降明显。③硕士与博士学位论文的研究主题都逐渐从传统、宏观层面的交通问题转为更加具象化的问题,并趋向于与信息技术相结合。Transportation-related interdisciplinary research is increasing.In this paper,the master and doctoral dissertations of transportation-related disciplines in the past 20 years obtained from the China Knowledge Network and Wanfang database were used as data sources to mine their main topics and evolutions and uncover the similarities and differences in the changing trends of hot topics.The results show that:①there are fewer postgraduate dissertations on air traffic,the mainstream research object is road traffic,and the most concerned research theme is train operation organization;②overall four themes such as train operation organization and traffic flow prediction have increased significantly,and four themes such as transportation policy and transportation project management have decreased significantly in master's dissertations;four themes such as train operation organization and target detection have increased significantly,and four themes such as logistics system optimization and intersection evaluation have decreased significantly in doctoral dissertations;③the research themes of both master's and doctoral dissertations have gradually changed from traditional and macroscopic-level problems to more specific problems,and tend to be integrated with information technology.
