Munich's Mobilitätsreferat finished rolling its rule-based LAPW signal-switching system out to all 650 targeted traffic lights by January 2025, on a network where 1,076 of 1,147 signals already read live traffic data.

The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Munich's Mobilitätsreferat runs LAPW (Lastabhängige Programmauswahl), a rule-based system using detector data from the city's traffic-responsive signals to switch green-wave coordination to whichever program fits current conditions. Adopted by the city council in October 2019 as part of the air-quality plan, LAPW now covers all 650 planned signals citywide, per a January 2025 city report.
