"Eastrail, a beloved trail destination in Seattle's Eastside suburbs, embodies both rich historical significance and vibrant contemporary usage."

The EasTrail system currently faces significant challenges impacting user experience, safety, and community engagement. 

Key issues include
a gap
in real-time information updates,
safety risks due to high-speed traffic,
and underutilization of the trail's natural and historical attributes.

"How might we leverage modern technology effectively gather and visualize real-time data on Eastrail's usage and trail user feedback, in a way that seamlessly integrates with the trail's environment and aligns with users' expectations of privacy and experience?"


I identified key challenges through user and stakeholder data analysis and interviews. Following UX/UI design principles, I refined solutions through research, ideation, usability testing, iterative development, and teamwork, enhancing the EasTrail experience.

Secondary Research

We conducted secondary research from design, technology, and business perspectives to inform our approach to enhancing the Eastrail experience.

Primary Research

In our comprehensive research, we conducted 19 interviews with trail users, gathered data from 1145 questionnaire responses, and performed field studies across 3 segments of EasTrail. Additionally, we engaged in two expert interviews to further deepen our understanding of user needs and preferences.

Users Questionnaire

While the overall user experience on EasTrail is positive, there are several issues on the trail that need addressing. However, there currently isn't an effective channel for reporting these problems.

User Interview & Context Inquiry

Expert Interview

Affinity Map

We used affinity map to find that the EasTrail User Interview & Field Study Results reflect a desire for engaging and educational experiences, community engagement through the trail, and the need for improved amenities and safety measures, particularly concerning fast-moving bikes.


We discovered 3 Personas.



Our affinity mapping sessions have synthesized habits and patterns of both EasTrail managers and users, revealing key insights and highlighting valuable design opportunities to enhance the trail experience.

Question Definition

Research indicates that

30% of users are dissatisfied with the clarity of signage.

40% consider the facilities subpar.

60% of local residents lack awareness about participation opportunities, highlighting deficiencies in community involvement and interactive features.
