Road condition monitoring for constrained and low-connectivity environments
SAHEL is Hodos Media’s road-monitoring programme. It develops practical, affordable and repeatable approaches to road condition assessment and maintenance planning, particularly where conventional surveys are costly or infrequent, secondary and rural roads are poorly covered, or terrestrial communications are limited.
Programme focus
SAHEL brings together work on road-authority needs, low-cost and passively collected data, vehicle-mounted sensing, remote sensing, GNSS, satellite communications, data governance, system architecture and integration with existing road asset-management workflows. The programme considers technical feasibility alongside institutional, regulatory, financial and operating conditions.
Technical questions
- Which road-condition indicators can be captured reliably using lower-cost or passively collected data?
- How can road-condition data be transmitted from areas with weak or absent terrestrial mobile coverage?
- What evidence, assurance, data-ownership and workflow integration arrangements do road authorities require?
- Which operating and commercial models are feasible where budgets and institutional capacity are constrained?
Project sequence
OurEO
Established technical and commercial feasibility questions for remote sensing in road management.
HDM-4 Phase 2
Added global user, market and operating-model evidence for an established road investment and management tool.
SAHEL Feasibility Study
Assessed the market, regulatory, institutional and financial basis for satellite-enabled road monitoring in Zambia.
SatComBox
Advances the programme through ESA requirements, architecture, proof-of-concept assessment and implementation planning.
Programme outputs
Outputs include stakeholder analysis, formal requirements, technical architectures, feasibility evidence, business cases, implementation roadmaps and a cumulative evidence base for later road-monitoring projects.
