Aachen's most visible smart-city work sits on the street: parking sensors, a mobility dashboard, and university-led pilots backed by federal Modernitätsfonds (mFUND) research grants and the city's smart.aachen.digital network — much of it grown out of RWTH Aachen's engineering faculties rather than one central programme.

The atlas documents 2 projects in Aachen, the earliest dating to 2020: 2 still running without a verdict. Every entry carries an evidence grade — the strongest here is official (2 entries) — and links its sources.

One city the atlas reads next to Aachen — the reason first, then the entries it rests on. Chosen by hand from the Aachen threads below, not counted out of them.

1. 🇩🇪 Bad Homburg

   Two German mid-size cities working the same kerbside from opposite ends: Aachen measures first — streetlight cameras feeding a live public dashboard — while Bad Homburg upgrades the paying side and is only now adding real-time displays.

   • ACUP Smart Parking Sensors ↔ Smart Parking & Digital Twin
   • Aachen Mobility Dashboard ↔ Smart Parking & Digital Twin

Every editorial link from Aachen's entries into another city, strongest first. Each one is a statement about two projects, not about two cities — the three above are the ones the atlas is willing to make at city level.

• 🇺🇸 San Francisco: SFpark Demand-Responsive Parking Aachen's video sensors from 2020 still run; San Francisco's comparable meter sensors were retired in 2013 for payment-data pricing instead.
• 🇩🇪 Frankfurt am Main: Traffic Pilot — City-Wide Signal Prediction Two mobility dashboards: Aachen bundles parking, bikes and EV charging; Frankfurt's app shows drivers the green-wave speed.
• 🇩🇪 Bad Homburg: Smart Parking & Digital Twin Bad Homburg upgrades meters with rebates and self-service kiosks; Aachen instead reads occupancy live from 41 streetlight-mounted cameras.
• 🇩🇪 Bad Homburg: Smart Parking & Digital Twin Aachen's dashboard already bundles live parking data citywide — the kind of real-time display Bad Homburg's upgrade is just adding.
