Overview
ISO 22085-3:2022 - Intelligent transport systems (ITS) - Nomadic device service platform for micro mobility - Part 3: Data structure and data exchange procedures specifies the data structures and application-level data exchange procedures for micro mobility services that use nomadic devices (P-ITS-S). It targets cloud‑based ITS interactions between personal ITS stations (P-ITS-S), vehicle gateways (V-ITS-SG) and central ITS stations (C-ITS-S) to support micro mobility use cases such as car sharing, parcel delivery, and first‑mile/last‑mile connections.
This part of the ISO 22085 series defines Data eXchange Messages (DXMs) and the message-level formats and procedures (pre‑trip, en‑route, post‑trip) needed to integrate micro mobility (MM) into broader ITS ecosystems.
Key topics and technical requirements
- Data structure definitions for a comprehensive set of DXMs, including:
- request-mm-status / mm-status-response
- stop-notify-mm-status / notify-mm-service
- charging-station-information, parking-space-information
- reservation-information, public-transit-schedule / reservation
- navigation-route-information, traffic-information, accident- and danger-zone-information
- warning-message, toll-balance-information, payment-information, return-information
- Data exchange procedures organized by trip phase:
- Pre-trip (UC 1.x): discovery, navigation-linked charging info, parking pre-scans, sharing/reservation workflows
- En-route (UC 2.x): traffic updates, MM status monitoring, mobile tolling, adaptive routing, on-the-way parking searches, keyless access
- Post-trip (UC 3.x): driving data reporting, charging/parking follow-up, parked MM location and shared vehicle return
- Interoperability focus: message-level compatibility between P-ITS-S, V-ITS-SG and C-ITS-S using standardized datasets (based on ISO 22085‑2).
- Terminology and roles defined for MMSP (micro mobility service provider), MMCS (micro mobility cloud server), MMCN/PCN networks and other ITS station concepts.
Practical applications and intended users
Who benefits:
- Micro mobility service providers (MMSP) implementing fleet management, sharing and reservation services.
- ITS system architects and integrators designing interoperability between nomadic devices, vehicle gateways and central ITS systems.
- Software developers building mobile apps, cloud platforms and DXM handlers for e‑scooters, e‑bikes, small EVs and shared micro vehicles.
- Public transit authorities and toll/parking operators integrating first‑mile/last‑mile services into multimodal networks.
Real-world uses:
- Seamless exchange of charging-station and parking availability with navigation apps
- Remote status monitoring and keyless access for shared micro mobility fleets
- Standardized reporting for tolling, payments and reservation flows across vendors
