Automotive Lighting Interaction UX Study
Heavy snowfall is unpredictable and can cause pedestrian slip accidents if not removed promptly. Existing snow-removal systems are designed for vehicles and large spaces, making them unsuitable for narrow pedestrian areas such as sidewalks and stairs. This project develops a compact autonomous snow-removal mobility system for pedestrian environments.
Questions
Q1. How can snow be removed in complex pedestrian environments?
- Limited access for vehicles
- Risk of ice formation
- Size vs. performance trade-off
Q2. Can snow removal be performed without human intervention?
- Safety risks in manual work
- Need for continuous operation
Q3. How can safety be ensured around pedestrians?
- Visibility
- Speed control
- Emergency response
