The lane-changing behavior of drivers usually has a negative impact on traffic safety. In order to ensure the safety of vehicle lane-changing and prevent traffic accidents

the risk situation of vehicle lane-changing behavior should be identified. Through the systematic study of a large number of relevant publications at home and abroad

a review of vehicle lane-changing behavior was conducted from three aspects: statistical analysis of the literature

keyword visualization

and data set analysis. The research hotspots of key influencing factors of vehicle lane-changing were summarized. By reviewing the risk assessment methods of vehicle lane-changing behavior at home and abroad

the common risk assessment methods based on traffic conflict and driving intention were summarized and analyzed. Finally

the current issues and potential future directions for the risk assessment of lane-changing behavior were discussed. The existing research indicates that the research on lane-changing behavior should be combined with the characteristics of the traffic environment

and future research should focus on lane-changing models that are more universal and portable. In addition

the changes in drivers’ driving intention and lane change decision adjustment are important research directions for the future risk assessment of vehicle lane-changing behavior. Based on the development of the Internet of Vehicles

future research should consider a wider range of influencing factors

use more traffic environment data

consider the impact of heterogeneous traffic flow environments on the risk of vehicle lane-changing behavior

and conduct more in-depth risk evaluation method studies. Researchers can use vehicle telematics to better understand driving behaviors and factors leading to traffic accidents

which opens up new opportunities and challenges for the study of comprehensive evaluation methods for vehicle lane change risk evaluation.
