Analysis of traffic operation and safety characteristics of highway continuous entrance section

In this paper, the authors take the highway continuous entrance section as the research object and analyse the traffic operation and safety characteristics of this section. Traffic data were collected by UAV, and trajectory data were extracted by Datafromsky to analyse the continuous entrance road section in terms of following, lane changing and traffic safety. The results show that the further to the midstream end, the more obvious the influence of downstream entrances on the front vehicle of the following convoy. The acceleration lane mergeable section in the upstream merge zone has a higher degree of severe conflict with the midstream zone, which is the key section for traffic safety improvement in the continuous entrance section.
