🤖 AI-generated city profile, summarising the source-checked entries below — how this works

Pittsburgh's smart-traffic idea came out of Carnegie Mellon and runs on a distrust of central control: Surtrac's AI signals negotiate with their neighbours, each optimising its own intersection. Its developers reported that the 2012 East Liberty pilot cut travel times about 25% and idling over 40%, and the network spanned 50 intersections by 2016. An outside on/off study later found fewer stops and steadier trips rather than uniformly shorter journeys.

The atlas documents 1 project in Pittsburgh: 1 with a documented success. The entry carries an evidence grade — the strongest here is peer-reviewed (1 entry) — and links its sources.

🇨🇳 Hangzhou City Brain Two AI takes on traffic: Pittsburgh's signals negotiate locally per intersection (2012); Hangzhou runs one central all-data brain (2016). 🇧🇩 Dhaka CASE Traffic Signal Automation Automated signals, opposite outcomes: Pittsburgh's AI lights scaled from 2012; Dhaka's sat unused as police kept waving traffic by hand. 🇹🇭 Bangkok BMA AI Adaptive Traffic Signals Bangkok retimes 74 junctions from central CCTV (2024); Surtrac instead spreads the AI across intersections that negotiate locally (2012).
