  1. Except, of course, you’re ignoring SCATS:
    Sydney Coordinated Adaptive Traffic System
    which was developed in the 1970s for Sydney, and spread throughout major Australian centres by the early/mid 1980s, and has been exported to many locatios worldwide.
    Specifically regarding real-time adaptive behaviour: From the Wikipedia page:
    Traffic Adaptive Operation
    ATC systems provide advanced method of traffic signal control called Traffic Adaptive Control where the operational timing plans including cycle length, splits and offsets are continuously reviewed and modified in small increment, almost on a cycle-by-cycle basis, to match with the prevailing demand measured by the detectors connected to the on-street traffic controllers.
    Installation count (roughly split into Australian/International groups)
    SCATS is installed at about 42,000 intersections in over 1800 cities in 40 countries. In Australia, where the system was first developed, the majority of signalised intersections are SCATS operated (around 11,000).
