Drivers’ and cyclists’ safety perceptions in overtaking maneuvers

Drivers overtaking cyclists on rural roads are a safety concern, as drivers need to handle the interaction with cyclist and possibly an oncoming vehicle. Improving maneuver’s outcome requires understanding of not only objective, measurable metrics, but also subjective, perceived each road user. Previous research has shown that is most at risk passing moment, when driver closest other. However, develop measures, it necessary know how both users perceive safety, by factors influence their perceptions during maneuver. This study measured in test-track experiment Sweden field test Spain. For cyclists, we developed Bayesian ordinal logistic regression models scores take input objective metrics representing different crash risks moment. Our results show while drivers’ decreases there vehicle low time-to-collision, cyclists’ reduced small lateral clearance high speed. Although our datasets heterogeneous limited, line previous research. In addition, presented this paper novel may be improved future studies once more naturalistic data become available. We discuss support infrastructure development regulation, policymaking, coaching, active systems, automated driving providing possible method for predicting safety.
