Redesign of Kontrollavgift.se
In this project, we worked on improving the website Kontrollavgift.se, a service that manages parking control fees on private property. The aim was to reduce unnecessary email inquiries and incorrect appeals by creating a more informative, educational, and user-friendly web experience.
My Role
My main responsibilities included:
-
Leading the Empathize phase, including usability tests and test scenarios
-
Developing a SWOT analysis based on the company’s needs and user behaviors
-
Designing components and structural logic in the prototype
-
Ensuring quality of flows and consistency across the interface
In addition, I actively contributed to all parts of the process: ideation, user journey mapping, sketching, prototyping, testing, and iteration.

The Design Process – Double Diamond
Discover & Define
We started by analyzing the existing website and identifying issues through:
-
Usability tests on the current version
-
SWOT analysis
-
Identification of false assumptions, e.g., that users believed the site handled all types of parking fines
Insights:
-
Legal language confused users
-
The FAQ was either overlooked entirely or perceived as insufficient
-
Many users submitted appeals without valid reasons, often in frustratio

Develop
We used Crazy 8 sketches and brainstormed solutions, followed by creating:
-
A mid-fidelity prototype to test structure and content
-
A high-fidelity prototype with improved flows and visual hierarchy
I worked on building and linking the different screens, as well as ensuring that all parts communicated a clear and understandable user experience.

Solutions in the Prototype
Right Path from the Start
-
An icon on the parking ticket visually matches the website → fewer misdirected visits
Your Chances – Statistics-Based Guidance
-
A new page shows the likelihood of an appeal being approved
-
The result can strongly influence user decisions and reduce impulsive appeals
AI Chatbot & Contact Form
-
Provides answers instantly without the need to email → reduces support workload
Clearer Language & Structure
-
Legal phrasing simplified into more accessible language
-
FAQ section highlighted and restructured
Photo Evidence & Transparency
-
Users can view photos of the parking violation to understand why the fee was issued




Results & Insights
Our tests showed that:
-
Improved language and statistics-based guidance directly influenced user decisions
-
A more educational structure reduced the need to contact support
-
Simple visual means (icon, structure, tone) could have a significant impact
What I Learned
This project strengthened my skills in:
-
Facilitating user tests with clear objectives
-
Making design decisions grounded in user behavior
-
Understanding how small changes in structure, language, and guidance can create significant impact in a frustrating context
I am particularly proud to have contributed to a solution that:
-
Reduces negativity and frustration among users
-
Relieves the company’s support team
-
Creates a clear, intuitive, and respectful user experience
