The Problem

Vulnerable road users have no simple way to receive the safety signals that connected vehicles already exchange. The design challenge was to take dense, real-time data, positions, hazard warnings, GPS accuracy, and message stats, and present it in an interface a cyclist or pedestrian can read at a glance, while moving, without distraction.

My Role

As UI/UX Designer, I owned the app's visual design and interface:

• Designed the full screen flow, onboarding, mode selection, live map, hazard warnings, and the data dashboard

• Built a clean, legible visual system suited to quick, on-the-move reading

• Designed clear warning states, like the collision alert, that communicate urgency instantly

• Organized dense technical data (GPS accuracy, message counts, location data) into scannable, easy-to-read cards

Design Approach

The guiding principle was clarity under pressure. A safety app can't afford visual clutter, so I prioritized large, glanceable elements: a prominent speed readout, immediate warning pop-ups, and a data panel that breaks complex information into simple cards.

I designed a short onboarding flow to introduce the app's two modes, and gave critical alerts, like the collision warning, a distinct, high-contrast treatment so they're impossible to miss. Every element was weighted by how urgently a moving user needs it.

Outcome

The design was implemented into a working mobile app used in a live V2X demonstration environment. It successfully receives and displays real-time safety messages in both operating modes, surfacing hazard warnings the moment they matter.

What I learned: designing for safety-critical, real-time contexts means ruthless prioritization. Every element competes for a user's limited attention, and clarity always wins over decoration.
