TL;DR

The short version

Problem

30,000 UW metro bus commuters rely on fragmented and inaccurate sources for arrival information, which leads to frustration when commuting.

Solution

The Bus Beacon replaces traditional bus stop signage with a dynamic lighted pole that offers real-time information in accessible formats for all users.

Impact

Featured on the UW Human Centered Design & Engineering department’s website and invited to pitch the Bus Beacon to Sound Transit’s head of innovation.

Personally? This project solidified my decision to career pivot and stretched my design skills to new mediums.

Final Design Solution: The Bus Beacon

Full case study below

Let’s start from the beginning…

The full story

The Problem

King County metro riders spend 1,199,548 days per year waiting for buses

43% of UW students, staff, and faculty commute to campus via public transit and spend 14-minutes on average waiting for the bus according to a study by Moovit

The Problem

This is where riders are waiting

The typical metro bus stops leave commuters without access to lighting, arrival information, or notification of route disruptions. All while standing on the side of busy, wet, Seattle streets.

The Problem

Existing route planning tools are unreliable

Currently, riders use various digital tools to route plan and track arrival times. However, these tools are wildly inconsistent and require internet, which creates barriers and uncertainty when commuting.

Problem Statement

30,000 UW metro bus commuters rely on fragmented and inaccurate sources for arrival information, which leads to frustration when commuting.

Research Findings

Access & Privacy

Users are uncomfortable providing location data into unfamiliar tech.

Solution is accessible to users without smartphones and operate without personal location data.

Notification Overload

Users are overwhelmed with texts, notifications, alarms, and emails.

Solution allows users to pull information when they need it and does not contribute to push notification overload.

Delays & Disruptions

Users want to know arrival times of next buses, notifications of major disruptions, and options when delays occur. 


Solution provides all arrival information, including appropriate error states for when delays occur.

Ideation

Design Solution

Designed to be intuitive, informative, and accessible, the Bus Beacon replaces traditional bus stop signage with a dynamic lighted pole that offers real-time arrival information.

Key Features

  1. Passive solution at the stop

  2. Dynamic lighting for visibility & safety

  3. Error states for closures/delays

  4. Simple arrival countdown

  5. Accessibility-first design

  6. Smartphone-free interaction

Accessibility-first design

Dynamic, multi-sensory arrival information delivered to all users, including people with disabilities, users without smartphones, and those with limited reading or English comprehension.

  1. Audible chime before arrival

  2. Simple, icon-based info

  3. Visual countdown (HH:MM)

  4. QR code & additional resources

  5. Refreshable braille display

  6. Information display located at ADA accessible height for people in wheelchairs.

Beyond delays

Beyond arrival information, the beacon displays route error states. If a line isn’t running, the bus stop closed, or a route diverted due to inclement weather, the beacon lets users know what to expect.

Upon resume in service, the beacon would return to the success state and resume loading to the top until the bus arrives.

Digital Companions

Users want autonomy for how and when they receive arrival information. While Bus Beacon is a physical-first solution, users can access information remotely with corresponding digital tools.

The Bus Beacon widget displays route number, arrival time, and stop location, passively delivering arrival information without requiring secure location data.

Existing Stop

- Lacking real-time arrival info
- Unreliable digital companions
- Complex timetable data
- Static signage requires manual updates
- Dimly lit bus stops

Bus Beacon

+ Real-time arrival data
+ Operable without additional tech
+ Simple, icon-based information
+ Multi-sensory interaction
+ Push closure updates immediately
+ Integrated lighting

Project Impact

Since completion, the Bus Beacon has been featured on the University of Washington’s HCDE website and piqued the interest of Sound Transit’s department of innovation

Reflection

The Bus Beacon was my first end-to-end design project in UW’s HCDE Master’s program and it was a wild ride. The project started out studying the behavior of car commuters, and morphed through several rounds of problem redefinition and user feedback. Throughout this process, I saw firsthand how negative feedback on our initial push notification system—though tough to hear and initially causing mild panic—ultimately led to a more user-centered solution. I learned how to storyboard and animate digital sketches, conduct rapid prototyping and user research, and created a project I’m truly proud of.

If tomorrow Sound Transit decided to pursue the Bus Beacon, some next steps would be: 1. Validate our initial assumptions around technology feasibility 2. Test accessibility with diverse users with disabilities, and 3. Conduct discovery research on scalability, phasing, and digital integrations.

Thanks for your time!
