An open-hardware roadside sensing unit and firmware stack that brings reliable traffic telemetry to cities that cannot afford commercial instrumentation.
Overview
Good traffic data should not be a luxury good. This completed project produced an open-hardware edge unit — roughly a tenth the cost of commercial alternatives — that performs on-device vehicle counting and classification, uploading only summaries to preserve bandwidth and privacy.
Outcomes
- Open-hardware reference design released under CERN-OHL
- Firmware achieving on-device classification at the edge
- Deployed across two pilot corridors and independently replicated by three partner groups
Legacy
The platform underpins data collection in several subsequent projects, including the current urban-mobility programme.
