Stara Zagora City Transport - rating from every bus
A QR code on every bus. Passengers rate anonymously, and the operator sees results per vehicle in real time.
The Challenge
The entire bus fleet, tens of thousands of passengers daily - and zero visibility into which bus has a problem. Feedback comes only from formal complaints, days after the ride.
Dirty interior, broken AC, delays - the operator learns only when the problem has already escalated. Without data, maintenance investments are blind.
The Solution
A QR code on every bus. The passenger scans and rates anonymously in seconds - cleanliness, punctuality, driver. Each rating goes to the specific bus.
The responsible team sees a management dashboard by bus, route, and period. When ratings drop - automatic notification.
Results
The entire bus fleet is covered - every bus is a feedback point. For the first time, the operator has data per specific vehicle.
The system is part of the Stara Zagora Municipality project, recognized in Top 9 at the Innovation in Politics Awards 2025. Every problem is visible and traceable to the specific bus.
"The goal is for the Municipality of Stara Zagora to become increasingly transparent, increasingly public, and increasingly open to its citizens — and to have ever-better interaction across different spheres."
