Overview - ISO/TR 4448-1:2024 (Public-area mobile robots, Part 1)
ISO/TR 4448-1:2024 is a Technical Report in the ISO 4448 series that provides an authoritative overview of the deployment paradigm for ground-based public-area mobile robots (PMRs). It defines the operational context where PMRs share kerbsides, footways, cycleways and other public pathways with human users and non-automated devices. The scope covers collaborative, co-temporal use by varied wheeled and ambulatory mobility devices - including automated or remotely operated vehicles that move people or goods - and explicitly excludes aerial drones.
Key topics and technical areas covered
The report organizes the PMR paradigm into technical and operational building blocks. Key topics include:
- Definitions and data: standardized data concepts and data profiles relevant to PMR deployments, including security, privacy, testing and threat/vulnerability considerations.
- Behaviours: expected PMR behaviours such as loading/unloading at the kerb (PUDO), access rules for human pathways, interaction with pedestrians, and PMR-to-human signalling.
- Safety and reliability: functional safety concepts, journey-planning sufficiency and Journey Data Recorder (JDR) considerations for incident analysis.
- Municipal readiness: pathway suitability, environmental worthiness, mapping maintenance, and post-crash procedures for PMRs.
- Personal assistants: transport and task-oriented personal-assistant robot categories operating in public areas.
- Operating and governance principles: contrasts between kerb, footway and cycleway operations, behavioural factors, and governance models for city-scale orchestration.
- Environmental and social considerations: climate/weather resilience and social impact including accessibility and fairness.
- Use cases and examples across delivery, inspection, maintenance, surveillance and passenger movement.
Practical applications - who uses this standard
ISO/TR 4448-1 is valuable for stakeholders planning or regulating PMR deployments:
- City planners and transport authorities - to assess kerb and pathway policies, PUDO management and municipal readiness.
- PMR manufacturers and integrators - to align product behaviour, communication signals and data practices with deployment expectations.
- Fleet operators and logistics companies - for operational planning, journey recording and safety practices.
- Standards bodies, regulators and insurers - to inform governance, liability and insurance frameworks.
- Software and mapping providers - for route planning, mapping maintenance and JDR integration.
- Accessibility and urban design professionals - to evaluate social impacts and pedestrian interactions.
