How this atlas is made · What “last verified” means

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.
