Abstract

For a long time to come, both autonomous vehicles (AVs) and human-driven vehicles (HDVs) will be traveling on the road at the same time. This paper focused on three aspects of research: the current research status, the research method, and the influencing factors. Firstly, bibliometric methods were employed to clarify the re-search focus on highway capacity. Secondly, the study classified and reviewed the research methods in highway capacity research and summarized the research framework. Thirdly, we summarized and analyzed the factors of highway capacity studies on different road types according to three categories. Finally, we proposed future research directions based on the current status of capacity research under different road types and influencing factors. We believe that the in-depth analysis of the key influencing factors of highway capacity and enhanced research oriented to the calculation model of special road capacity will effectively promote traffic flow management by traffic managers.
