Wait Region Ranking as an ML (Machine Learning) Product
Ranking which regions burn waiting time becomes a product consumed by wait dashboards and geofence reviews.
rank(region) → API → ops list + map
Fleet Wait Geofence UI bu sıralamayı okur.
Concepts, defined where they first appear
📦 OSRM
Open-source road-network shortest-path engine used as the recommended-route baseline.
📦 Preferred Path
The path drivers actually take — recovered from telemetry traces.
📦 Km Extension
Extra kilometers of the preferred path versus the OSRM baseline.
📦 Wait Hotspot
Geographic cluster where waiting events concentrate.
Blurring these layers produces the wrong truth in analytics and on the map UI.
Shape of the problem
Ranking which regions burn waiting time becomes a product consumed by wait dashboards and geofence reviews.
rank(region) → API → ops list + map

↓
explicit contract → frontend
Frontend bridge
Ops maps, wait-geofence UI, and MFEs consume these read models — they never bind to raw ERP/MySQL.
The mappings that get confused most often
❌ ERP MySQL = analytics database
✓ ERP is a write store; analytics lives in PostGIS
❌ Let the map trust public/vendor routers blindly
✓ Production needs your API/OSRM edge
❌ Log ML outputs with PII
✓ Evaluation and serving obey privacy boundaries
A checklist for auditing your own system
- Which store is source of truth for this surface?
- Which API contract does the frontend call?
- What happens if one cluster node dies?
- How is lag shown to operators?
- Deny-list: any client domain/vendor leakage?
What to take away from this part
- Polyglot stores exist for different workloads; one-DB fantasies are fragile.
- Frontends consume clean read models, not the ERP.
- ML/OSRM outputs need an API contract before they hit the map.
A beautiful map drawn from a dirty source is still a lie.

Engineering Principles Learned
- Separate the operational store from the analytics store.
- Telemetry, search, and relational GIS have different access patterns.
- Every read model is a frontend contract.
