This page lists the SKI+ mobility data standards that are relevant to the future NADIM (National Data Networking Infrastructure for Mobility) from today’s perspective.
The following documents each contain a description of a specific standard, responsibilities, important links, underlying technologies and standards, application and data sets in Switzerland, our assessments, assessments, specifications and recommendations as well as a Switzerland profile (in terms of implementing provisions, Realisation Guides).
Concepts
Discussion basis for a NADIM standardisation concept
This document is primarily aimed at specialists and developers. It forms a basis for the standardisation in mobility data in the interim period until the NADIM is commissioned and for the standardisation by the NADIM operator.
Commentary
This document describes all standards and profiles provided for SKI+. The original can be found on the FOT website.
SKI+ standardisation roadmap
Based on the standardisation concept, the following overview summarises the proposed standardisation concepts by time, type of introduction and obligation.
On-demand SKI+ transport services
On-demand services are services where the customer can order a journey via a booking process, often without a timetable. This document forms the technical basis for understanding and implementing on-demand. For its implementation, please refer to the technical concept on-demand.
Data exchange for vehicle pooling in Switzerland – Proposals for viable and sustainable solutions
The purpose of the following paper is to develop a discussion basis for a common understanding of vehicle pooling (also known as car-sharing) in Switzerland. This means with regard to the companies operating in Switzerland, their business models, the conceptual and technical representation of their offers, as well as the possible provision of these as a central web service or data export.
The paper and the resulting discussions are intended to help the Federal Office of Transport, as the contracting party for SKI+, to decide whether and to what extent they wish to implement the proposed services and data in line with Switzerland’s National Mobility Data Networking Infrastructure (NADIM). We can then develop a joint infrastructure that allows providers to send their requests and offers to opentransportdata.swiss and allow OpenJourneyPlanner to use them.
Combination of Open Journey Planner OJPFareRequest with TOMP-API (Document is only available in English)
The Open Journey Planner (standard and our SKI+ system) calculates intermodal travel chains. OJPFareRequest can be used to price individual travel segments. A protocol change is required for the following steps of booking request, booking and use. The TOMP-API protocol is suitable for private providers such as taxis, shared mobility, etc. In this paper, we investigate how the protocol change from OJPFareRequest to TOMP-API /planning/enquires would be carried out.
From MMTIS 2017/1926/EU to a NAP Mission Statement in Switzerland (Document is only available in English)
This is an analysis of the data categories defined in the 2017 EU MMTIS Regulation (2017/1926), including updates to the most recent change (2024/490). MMTIS only defines high-level categories which have to be coordinated and mapped to specific standards (CEN Transmodel and others), profiles and implementation guidelines and finally to specific data sets and APIs. This is important for the Swiss National Access Point in our endeavour to provide interoperable data and APIs for Swiss and international mobility solutions.
OJP white paper: Implementation considerations for intermodal routing based on OJP (for clients and servers) in OJP 2.0
Das “Whitepaper Sharing” ist ein Konzeptbeschreibung, wie verschiedene Probleme bei der Anfrage an OJP-Router, betreffend der Ersten- und Letzten-Meile gelöst werden sollen. Es werden nicht alle Fälle abschliessend beschrieben. Weitere Details bei VDV auf GitHub: https://github.com/VDVde/OJP
Wir als SKI+ haben bereits ein Interface mit OJP 2.0 veröffentlicht (https://opentransportdata.swiss/de/cookbook/ojp2entwicklung/), welches die im Whitepaper beschriebenen Funktionen jedoch noch nicht vollumfänglich unterstützt.
Profiles and technical standards
General Transit Feed Specification (GTFS) PROFILES SWITZERLAND
General Transit Feed Specification (GTFS) is a digital exchange format developed by Google for public transport timetables and the associated geographic information such as stop locations. The data is provided by transport companies and published as a consolidated database. The data is used to develop applications related to public transport, such as timetable enquiries.
Commentary
This format is used exclusively for Export of data and can not for the import.
General Bikeshare Feed Specification (GBFS)
Standard for shared mobility data. This standard is a world leader and is used in Switzerland by the Swiss Federal Office of Energy (SFOE)
Open Journey Planner (OJP) Switzerland profile
Standard for travel information
Commentary
Coordinated with the FOT, published on 2023-01-01.
TOMP API Profile Switzerland
Currently leading standard for MaaS (Mobility as a Service), particularly with regard to the booking workflow (from offers to payment) in the area of intermodal mobility.
Commentary
The TOMP profile is currently under development.
SIRI VM profile Switzerland
The following profile has been defined based on SIRI VM for transmitting vehicle positions in the Swiss public transport system. Only coordinates are used.
Commentary
SIRI VM remains in the draft until data is actually provided.
We offer the draft standard in English only.
Occupancy Forecast
An occupancy forecast is a forecast (prediction) about the occupancy rate of a specific means of transport (train, bus, etc.) that is expected at a certain time in the future.
Commentary
It is usually displayed with doll symbols (1, 2 or 3 dolls).
This document is intended to establish the basis for an efficient, standardised exchange of occupancy forecasts of vehicles (trains, buses, etc.) in public transport and, if necessary, also for private mobility providers (on-demand services, carsharing, etc.) in Switzerland.
Open Interchange Protocol (OICP) Switzerland profile
Data standard for the data exchange and interoperability of electric vehicle charging stations.
Commentary
Coordinated with the FOT, published on 2023-02-21.
OpenStreetMap (OSM) – use in OJP/ODMCH and consideration of optimal data collection in OSM for mobility with a view to a future mobility data space
OpenStreetMap is an important geodatabase for mobility. This document describes how optimal modelling of mobility in Switzerland could take place from a SKI+ perspective. The modelling relies heavily on already defined guidelines. Additions are made for specific aspects, such as the SID4PT identifiers.
Conceptual standards
Transmodel
The Transmodel CEN standard is recommended as the basis for . If possible, interface standards based on Transmodel or similar should be used: NeTEx for timetables and services, SIRI for real-time and disruption information, OJP for journey planning, DATEX II for road traffic.
Commentary
Standard for Q3 2022
Profile for Q4 2022
