Most collision data involving vulnerable road users (VRUs) are sampled based on the presentation of injury or rely on police-reported collisions, which serves to capture higher severity events while failing to include vehicle-to-VRU contacts in which VRU avoidance may mitigate injury presentation. The objective of this study was to characterise VRU pre-collision posturing and post-collision outcomes to inform improved risk assessments. Leveraging dash-camera video and sensor data from third-party vehicles involved in collisions with VRUs, 523 events were reviewed to assess environmental factors, avoidance behaviour, collision features, and post-collision outcomes. Relationships between vehicle speed and VRU knockdown were presented to highlight the additional injury mechanism of falling to the ground. Visual occlusions were observed in approximately 25% of cases. VRUs were considered to observe the impending collision event in 54% of cases and performed an avoidance manoeuvre in approximately 89% of these cases. These dash-camera data highlight that the vehicle being visible to the VRU is critical to having the potential to mitigate collision outcomes. Collisions at speeds exceeding 10 mph (16 km/h) are likely beyond the reasonable limits of stability for VRUs to maintain an upright position and avoid potential injury associated with falling to the ground.
