Surabaya's traffic control room dates to the 1990s and has run Australia's SCATS software since 2010 — but no independent study says whether the 130-plus linked intersections actually cut congestion.

Surabaya's traffic control room traces to an Area Traffic Control System first built in the early 1990s and rebuilt on Australia's SCATS platform from 2010, run from a 24-hour operations centre at Terminal Bratang that links signal timing to live camera feeds across the city. City reporting in May 2026 said the system, now branded SITS, feeds into the same integrated digital-services push as the transport department's other apps, and the department's own account puts the network at more than 130 signalised intersections with hundreds of connected cameras by the mid-2020s. No independent study of travel-time or congestion gains was found.
