Traffic conflict can be identified by the presence of evasive actions or the amount of temporal (spatial) proximity measures like time-to-collision (TTC). However, it is not enough to use only one kind of measures in some scenarios and it is hard to set a threshold for those measures. This paper proposed a method to identify traffic conflict by learning the representation of TTC and driver maneuver profiles with deep unsupervised learning and clustering the representations into traffic conflict and non-conflict clusters. We first trained a transformer encoder to encode sequences of...

New research brief explores the impacts of pluralistic ignorance on traffic safety perceptions

At the heart of active transportation systems are the people that use them. In a new research brief, Peer Influence and Perceptions of Safety, UC Berkeley SafeTREC's Graduate Student Researcher Aqshems Nichols and Co-Director Jill F. Cooper discuss the importance of considering perceptions in traffic safety analyses and the potential for investigating how a psychological phenomenon known as pluralistic ignorance could be shaping those perceptions.

Pluralistic ignorance is a "...
