Challenge
Transportes Metropolitanos de Lisboa (TML), the mobility authority for the Lisbon Metropolitan Area, manages the integration of public transport systems and ticketing across the region. With more than 2,500 vehicles operating daily, TML needed a modern, scalable, real‑time platform capable of processing 10 million daily transactions and supporting 1 billion yearly validations across operators, ticketing systems and digital mobility services. TML required an architecture able to ensure resilience, low latency, high throughput and seamless integration across multiple transport operators and legacy system, while preparing the region for future digital mobility initiatives.
Solution
Link designed and delivered an event‑driven integration platform built with:
- Solace PubSub+ for real‑time, reliable event streaming
- Open‑source technologies for extensibility and cost‑efficiency
- A scalable event‑driven architecture that supports continuous information flow between vehicles, ticketing systems and central mobility services
