About Keolis

Keolis is a shared-mobility group operating in 13 countries. Based in France, it develops and operates public transportation systems in partnership with public authorities.

Its fleets include vehicles of different brands, types, models, and ages. This makes consistent information about vehicle condition particularly valuable to maintenance teams.

Planning maintenance with vehicle data

Stratio’s fleet reliability intelligence analyzes data from across the fleet to identify developing faults and component wear. Diagnostic AI helps Keolis monitor individual components and plan repairs before a vehicle fails in service.

Stratio also automates routine activities such as distance-based servicing and fluid-level checks. Daily reports highlight critical alerts, helping teams prioritize work and schedule maintenance during quieter periods.

Responding faster and prioritizing maintenance

Critical issues are flagged in real time, so operations teams can respond faster and avoid disruption to passengers. Developing, non-urgent problems are detected, described and organized automatically for the maintenance team, so periodic checks follow what each bus actually needs rather than a fixed checklist, and workshop time goes to fixing real problems.

Improving fuel efficiency

Keolis uses Stratio’s ecodriving tools to analyze driver behavior. Driver scores turn that data into practical feedback intended to reduce fuel consumption and CO2 emissions.

Monitoring electric-bus batteries

Keolis technicians use Stratio to monitor the actual capacity of each electric-bus battery pack and how it degrades over time. That visibility supports Keolis’s conversations with OEMs, giving both sides a shared view of this critical system.

“The Stratio solution, which is already deployed on several Keolis networks in France, allows maintenance staff to view and address vehicle failures. This eliminates costly downtime, enabling us to provide an even more reliable, efficient and safe service for passengers.”
