Vulnerable Road Users

Research on pedestrians, cyclists, and micromobility riders: their behavior, their crash patterns, and how drivers and vehicles interact with them.

What's here. Pedestrian behavior perception, child pedestrian, cyclist safety, and micromobility e scooter studies, plus vru crash typology, the crash configurations specific to people outside a vehicle. Also driver vru interaction at crossings and yielding, and vru facing ehmi, meaning signals a vehicle shows outward to pedestrians and riders.

What isn't here.

• motorcycle and moped riders, including motorcycle_crash_typology — Two-Wheeler & Motorcycle Drivers. Riders are commonly counted as vulnerable road users, but they have their own category here. This shelf stops at pedestrians, cyclists, and micromobility.
• general crash_typology and configuration coding that is not specific to road users outside the vehicle — Crash Causation & Contributing Factors. vru_crash_typology here covers only pedestrian, cyclist, and micromobility crash types. Whole-fleet crash typing and causation analysis sit in crash_causation_factors.
• interfaces aimed at the driver, including voice interaction, display design, and warning design — Human-Machine Interaction. vru_facing_ehmi is the outward-facing half of that split: what the vehicle communicates to people outside it. In-cabin interaction is in hmi.
