Rebuilding the ORCA Business Passport zone cost estimatorDesigned like a transit agency's case file: sections are stops on one route line, research is filed as stamped reports, and Metro's signage sets the colour and type.

Overview

At King County Metro, I rebuilt the zone cost website for businesses that use ORCA cards for employee transit benefits. ORCA is the smart card riders use to pay transit fares across the Puget Sound region.

The goal was to streamline onboarding for new business accounts and make cost and account management clearer and more accessible.

What I did

  1. 01
    User research Interviews and surveys with local companies on what business account managers struggle with.
  2. 02
    Rebuilt key pages With the development team: easier to navigate and in line with Metro's brand guidelines.
  3. 03
    Redesigned zone-based fares So the complex fare structure is easier to understand.
  4. 04
    Tested with real users Gathered feedback and iterated on the prototypes.
  5. 05
    Built in accessibility Navigability, a clear text hierarchy and readable colour contrast.

Problem

FromProblem

Hard to use; zone costs were unclear.

ToGoal

An accessible estimator built for businesses.

How can businesses work out their transit zone costs quickly and accurately?

The old ORCA calculator: a dense spreadsheet-like table

Where we started: the old ORCA calculator, a dense table that asked businesses to work out zones and prices themselves.

Research

I started by mapping who uses the estimator and what each side of the team needed from the rebuild.

  • Can we launch as soon as possible?
  • It has to work well on phones.
  • Keep it consistent with the other Metro pages.
  • Let people look up their zone or area.
  • And add a section with program info.
Software teamSimple, one page
  • Keep it simple.
  • Fewer confusing visuals, please.
  • Users should stay on the same page.

Audit

I reviewed the old site against Nielsen's usability heuristics and rated each issue by severity (0–4).

  1. Error prevention

    Navigation paths were inconsistent, and key features took several clicks to reach.

    4/4
  2. Visibility of system status

    Users found the interface cluttered and confusing.

    3/4
  3. Recognition rather than recall

    Without a visual hierarchy, primary actions were hard to tell apart from secondary ones.

    3/4
  4. Aesthetic and minimalist design

    Poor mobile accessibility frustrated people using it on the go.

    2/4

Constraints

The redesign had to work inside real limits, so a lot of the job was choosing what was feasible.

Technical limits

The existing architecture and a small engineering team made some modern features hard to build.

Budget

A strict budget meant improving the existing infrastructure instead of replacing it.

Platform complexity

The old platform's fragmented structure made both the user experience and backend management harder.

Team capacity

I balanced user needs with what engineering could ship, and worked closely with engineers to get the most out of it.

Design

The new estimator walks a business through three steps: find your zone, estimate your total cost, and contact the Passport team.

The full new Passport zone cost estimator page

The full new page. Scroll inside the frame to follow the three steps.

  1. 01
    Key services first. A simpler interface gets people to the information they need without extra steps.
  2. 02
    Better search. A more intuitive address search finds a business's zone quickly.
  3. 03
    Clearer navigation. Fare information and customer service are easier to find.

The rebuild also improved the overall user flow, made future updates possible without a major overhaul, and added real-time transit data the old platform didn't have.

Before & after

Dead clicks34873−79%

Rage click: rapid clicks on one element, a sign of frustration. Dead click: a click that does nothing.

Impact & reflection

The redesigned platform improved usability and accessibility, helping business users manage their ORCA program and employee transit benefits. Feedback showed a 32% boost in user engagement, less confusion about the fare structure, and account management that felt more intuitive.

The project let me dig into the needs of very different business users, from small companies to large corporations. Seeing iterative design make a real difference in usability testing was the most rewarding part.

Working closely with developers and stakeholders, I learned to balance business goals with user needs while keeping accessibility a priority. It strengthened my research and design thinking, and my interest in building user-friendly tools for the public sector.
