Investigating Secondary Interactions: Are Drivers Paying Attention to Pedestrians When Exiting Non-signalized Intersections?

Most studies investigating pedestrian-vehicle interactions at non-signalized intersections have focused on interactions at the crosswalk on the same approach the vehicle is coming from, which are called primary interactions in this study. However, secondary interactions, defined as interactions between vehicles exiting the intersection and crossing pedestrians, have not been studied by themselves; these interactions can be dangerous due to driver’s unclear knowledge of right-of-way, acceleration attempts to recover the speed, and the complex situation the driver faces in the intersection. This paper’s goal is to highlight the safety issue of secondary pedestrian-vehicle interactions at non-signalized intersections. For that purpose, a case study involving ten all-way stop intersections from Montreal, Canada, was conducted by collecting video data. Different measures are used in the study: from the interaction analysis (behavior measures based on a Distance-Velocity model), average crossing speed analysis and vehicle approaching behavior analysis (approaching speed and acceleration). Primary and secondary interactions are analyzed and compared. Results show that secondary interactions are more dangerous compared to primary interactions. Among the three secondary interaction types, secondary through interactions are the most dangerous.
