Operational since 2008, the BTMS gives Bucharest centralised, adaptive control of traffic signals across roughly 100 junctions in the inner ring, with CCTV, fibre links and priority for surface public transport — an ageing, induction-loop-based system that has worked only intermittently for years. Its long-planned refresh keeps slipping: in May 2026 the city approved feasibility studies for a first modernisation phase of 92 intersections (305 AI cameras and about 1,500 magnetometric sensors, 14 months of works) plus a new command centre, but the EU recovery (PNRR) contracts worth about 73 million lei, signed in 2023, lapsed unused because works could not be completed by the July 2026 deadline. The city is now seeking roughly 85 million lei from the Bucharest-Ilfov regional development agency instead.

🎓 Lesson

A city-scale traffic platform is a multi-decade commitment: Bucharest's 2008 system needed an operator handover to stay alive, and its EU-funded refresh was contracted in 2023 yet never broke ground — the recovery funds lapsed at the July 2026 deadline with the studies done and the works unstarted.
