Challenges

Fragmented Mobility Experience

Travelers often rely on multiple apps for planning and payments, leading to frustration.

Lack of Seamless Multi-Modal Integration

Public transit, shared mobility (bikes, scooters, ride-hailing), and personal transport are not always connected into a single journey.

Traffic Information Overload

Users receive long, generic, and often irrelevant traffic updates, making it hard to quickly assess disruptions.

Strong Competition

Competing apps like Google Maps & Citymapper offer smoother interfaces and cutting-edge technology.

Project Goals & Solutions

Ensure an Integrated, Seamless Passenger Experience

🎯 Goal

Unify all transportation modes, including public transit, shared mobility, and personal vehicles, into a single journey.

💡 Solution

Modalities such as carpooling, park-and-ride or bike space reservation are gradually being added to the functionalities.

Make Traffic Information More Relevant & Accessible

🎯 Goal

Improve clarity and personalization of real-time traffic updates.


💡 Solution

Designed an AI-driven traffic summary to deliver personalized, digestible insights instead of lengthy reports.

User Testing Insight: Initially tested a chatbot for traffic updates—users found it disruptive. Pivoted towards integrated AI-powered summaries, which received better feedback.

Enhance Personalization & Daily Travel Experience

🎯 Goal

Help users plan and adjust their commutes with intelligent, user-focused solutions.


💡 Solution

Developed personalized daily commute widgets to provide relevant updates at a glance.

Process & Design Approach

🔍 Continuous Discovery & Framing
  • User feedback monitoring, business goal alignment and official regional guidelines influence feature prioritization for each Program Increment (PI).

  • Close collaboration with Product Owners (POs), Product Managers (PMs), and business teams.

🧭 Design & Validation
  • Each feature starts with hypotheses, followed by internal reviews with design, PO, and business teams.

  • Once the concept is solidified, we test with users to validate or refine our assumptions.

📬 Delivery & Developer Collaboration
  • Design handoff is structured but flexible, ensuring close collaboration with developers.

  • Participate in refinement meetings and maintain an open Slack channel for real-time communication.

Challenges Along the Way & How We Solved Them

Growing Product Complexity 

The app started as a small project but has scaled rapidly. No design system was in place, making the design process more challenging.

💡 Solution

With another designer, we initiated a reverse-engineered design system to standardize UI components and streamline workflows.

Technical Limitations 

Some backend constraints limit functionalities eg. such as the ticket calculator not being able to handle every possible commute scenario.

💡 Solution

We collaborated closely with developers and business teams to define simple, effective rules that covered most cases, ensuring accurate pricing in the majority of situations while keeping the system scalable.
