Transportation Network CH

With Transportation Network CH, users will in future be able to combine spatial mobility data in a highly automated manner for the first time – even across national borders. These combinations will allow them to obtain completely new information and use it to design applications that were previously impossible. Transportation Network CH thus makes a significant contribution to more efficient mobility in Switzerland.

What is the purpose of Transportation Network CH?

The aim is for Switzerland’s mobility system to become more flexible, smarter and more sustainable. There is still great potential here. In order to make the most of this, a reliable data basis is needed. A large amount of data on mobility and transport infrastructure is already available – however, this data is in different locations and is usually difficult or impossible to link. To make better use of it, the Swiss federal government is working on a national mobility data infrastructure (MODI).

The aim of MODI is to make the information about the Swiss mobility system more accessible and to link data more effectively (or link it in the first place). In future, this will enable mobility services to be increasingly optimised using data, and infrastructures to be utilised and planned more efficiently. As an important part of the MODI, Transportation Network CH will be used to link spatial data.

What exactly is possible with Transportation Network CH?

Transportation Network CH includes tools and functions that will enable users to link spatial mobility data in a highly automated manner in the future. In doing so, they will be able to combine both their own data and freely accessible data from third parties.

Transportation Network CH in detail

What benefits does Transportation Network CH create?

New combinations of existing data form an important basis for the efficient planning and management of the transport infrastructure as well as for innovative applications and services in the mobility and transport sector. This benefits the public sector, business and society:

• Municipalities, cities, cantons and the Swiss federal government

  Specialist bodies for mobility, transport infrastructure, spatial development, the environment and geoinformation

  • Planning and transport management are simpler and more efficient. Thanks to the tools provided by Transportation Network CH, the public sector can generate new data combinations. These can be used, for example, to create traffic models more easily, implement infrastructure projects, maintain traffic flow or efficiently manage public transport and stationary traffic. Changes to roads and paths (e.g. due to construction sites, changed signs, diversions) can be made accessible to others (e.g. map services) by the authorities via Transport Network CH.
    Example of best practice: Traffic management during the UCI Road and Para-Cycling World Championships in Zurich
  • Data will in future be accessible and linked  across borders (municipal, cantonal and national borders); data consistency with border areas will be enabled.
  • Authorities can link their respective data: Provided that they are permitted to use each other’s data, different specialist bodies will in future be able to combine their data using the Transportation Network CH tools. This will allow them to use existing information without having to without having to enter it all over again. This ensures less redundancy in data collection, maintenance and provision. The data always remains in the possession of the original owners.
  • Expansion and optimisation of official data: In future, official data can also be combined with purchased or community-based open data and thus expanded. The Transportation Network CH functions will also make it possible to detect and rectify any errors and gaps in the official transport network.

• Emergency services and the armed forces

  • In the future, the fire brigade, rescue workers and the police will be able to determine the fastest route to the scene of an emergency by combining, for example, real-time information on traffic density, obstacles and special access restrictions via the Transportation Network CH functions. This prevents time being wasted on the way to the scene and thus helps to save lives.
  • The armed forces can, for example, plan the routing for their special vehicles during troop movements. Thanks to the Transportation Network CH functions, they will be able to easily combine data on the transport network and its status. For example, they can link clearance profiles, weight restrictions and information on current road conditions from different sources.

• Traffic planning, passenger transport and freight transport [NR1]Eher Traffic

  Traffic engineering offices and planning teams

  • The linkability and combinability of different technical data will simplify data preparation for traffic engineering offices and planning teams in the future and enable new applications. For example, they will be able to efficiently combine and use publicly available data on traffic figures, traffic light systems and traffic information from the FEDRO Traffic Data Platform (VDP) with other data.
  • Planning and traffic management will become simpler and more efficient, as the required information can be gathered more easily.

  Mobility providers

  • The Transportation Network CH tools will make it easier for mobility providers to link information from different mobility services in the future and thus create intermodal traffic services.
  • The basic data provided by Transportation Network CH (basic network) is multimodally linked. In other words, the data shows where there are connections between roads, railways, waterways and cableways and thus offers additional high-quality information.
  • New business models will be possible, and customers will be able to use existing mobility services more easily and combine them with each other.

  Transport companies

  • The available Transportation Network CH tools will enable transport companies to supplement their own data with other, freely available mobility data in the future and exploit synergies with other logistics providers.
  • For example, they can combine information on road traffic, rail transport, shipping and transfer stations. In this way, intermodal freight transport can be planned more easily and more efficiently.
  • By linking their data with other information, logistics companies will be able to plan their routes better and deliver reliably and on schedule.

  Software and app developers

  • — Thanks to the uniform database, software and app developers will be able to combine data from different specialist areas, develop new, combined offerings and continuously improve mobility services. As the software components developed for Transportation Network CH are provided as open-source, editable and freely usable resources wherever possible, software developers can incorporate them into their own applications and easily develop them further.

• Map and routing services

  • With Transportation Network CH, map and routing services will be able to easily integrate data from other sources.
  • Transportation Network CH creates the desired direct channel between administration—which can supply up-to-date information on changes to the transport network (e.g. construction sites)—and the providers of digital maps. This improves the topicality of map products and routing services (e.g. for navigation), which in turn benefits the public sector and the general public.
  • Transportation Network CH makes it possible to combine information based on different transport networks and geodata bases. This significantly increases the usability of the data from map and routing services, as the advantages of the different data sources in terms of location accuracy, topicality, completeness and other relevant information can be combined.

• Science and research

  • Transportation Network CH provides scientists with easy access to up-to-date mobility data and its individual combination for research and study assignments, thus facilitating research into efficient forms of mobility.
  • Data processing when combining specialised data is simplified by linkable data and by open-source, freely available tools and software components.

• General public

  • The public benefits from a more efficient and sustainable overall transport system.
  • Innovative applications are created that allow users to select and combine mobility services simply and individually. This means that they can reliably reach their destination by various means of transport.

What has been achieved so far?

• What progress has been made with Transportation Network CH to date?

  Transportation Network CH is currently being set up in stages. The most important basic functions have been developed by the end of 2025.

  First products ready

  The “Matcher” is the first Transportation Network CH tool to be implemented. It enables users to reference a wide range of specialised networks to the basic network in a highly automated manner. The Matcher is not yet publicly available, but is already being used by selected project partners, who are testing it and creating their first specialised networks matched to the basic network. The project team is still optimising the tool in terms of its user-friendliness and performance.

  Another important step towards the full functionality of Transportation Network CH was the establishment of the basic network “swissTNE Base”. It is available for public download and is updated periodically in a traceable manner. The aim is for it to be continuously updated in future and to be dynamically accessible and integrable. The basic network is already being used independently: Liechtenstein is using it, for example, as a basis for digitally coordinating construction site and event traffic. During the UCI Road and Para-Cycling World Championships in Zurich, it served as a precise source of data to indicate closed sections of road and the corresponding diversions.

  Further products are currently in development

  The “Combiner” is a tool currently under development that will enable users to spatially combine specialist networks referenced to the basic network.

  Other tools are also being developed in parallel to this. These will allow users to configure their data (to create their own specialised networks and make them publicly available) and edit their created specialised networks (e.g. if combination with the basic network uncovers errors or gaps in data) at a later point in time.

• Project timeline

  

  2018 – 2020

  Initialisation: developing the project idea and basic principles

  In December 2018, the Swiss Federal Council decided to promote multimodal mobility more strongly in future. Swisstopo was then commissioned to analyse the setup and operation of a “Transportation Network CH”. The project team formulated the project idea, substantiated it in a study and developed the initial foundations. In doing so, it involved ARE, FEDRO, FOT and FSO as additional specialist bodies.

  2020 – 2022

  Concept and pilot phase: planning and reviewing the processes

  Based on the developed foundations, the Swiss Federal Council confirmed the need for a Transportation Network CH as the basis for the National Data Networking Infrastructure for Mobility (NADIM) in July 2020.

  The project team created a detailed implementation concept for Transportation Network CH. Pilot applications helped determine the needs of users, test the concept and confirm its feasibility.

  In this project phase, the team once again worked closely with the ARE, FEDRO, FOT and FSO federal offices, as well as with others responsible for mobility, transport and geoinformation.

  In February 2022, the Swiss Federal Council commissioned swisstopo to incrementally set up the Transportation Network CH.

  2023 – 2025

  System implementation: incremental development of the basic functions

  The Transportation Network CH project team has developped the basic functions for combining and linking traffic data by the end of 2025.

  The MODIG legislative proposal—which, among other things, is the basis for operating Transportation Network CH—was referred to parliament by the Federal Council in May 2025.

  2026 – 2028

  Development: expanding the range of functions and preparing for operation

  A selective expansion of functions will take place from 2026 to 2028. In coordination with the overarching MODI project, the project team will focus on the functions required to implement the prioritised use cases. Preparations will be made for operations at swisstopo.

  From 2028

  Operation and further development

  The new federal law on the mobility data infrastructure (MODIG) will govern the operation and further development of Transportation Network CH. With the entry into force of MODIG (expected at the beginning of 2028), Transportation Network CH—one of the main elements of MODI—can start long-term operations. From then on, the full range of functions and data can be developed.

• Achievements: our greatest successes

  • Automated matching solved: For the first time, Transportation Network CH enables the highly automated linking of spatial mobility data from various sources without having to fundamentally change their structure. This allows the data to remain locally with its original owners. To do this, the data must first be referenced on a common basis. The tool required for this—the “Matcher”—has been implemented and is currently being optimised in terms of user-friendliness and performance.
  • Common reference available: The basic network as a common reference for the wide range of mobility data has been set up, is being updated and is already being usedin use.
  • Significant support and a great deal of demand evident: Transportation Network CH is funded by the Federal Administration and receives a great deal of support from stakeholders in the areas of mobility, transport and geoinformation. Numerous public and private organisations—including cantons, cities and municipalities—have shown a strong interest in using Transportation Network CH. Partnership-based pilot applications are already running successfully.
  • Transportation Network CH already in use: Various organisations are already setting up applications and data products using Transportation Network CH, simplifying their processes and using this improved starting point to add value to their data on transport infrastructure and mobility. For example, the Principality of Liechtenstein is already using the basic network as a high-quality geodatabase for digitally coordinating traffic at construction sites and during events.
  • Legal basis under development: The Federal Council is committed to the Transportation Network CH project, and the legal basis for operation—the Federal Act on Mobility Data Infrastructure (MODIG)—is currently being reviewed by the parliament.
