Probe Vehicle Data

Probe Vehicle Data

The importance of data for traffic and transport, and certainly for road management, is increasing rapidly. While previously road-bound measuring systems dominated, new possibilities are created by sensors in the vehicle. For example, more and more vehicles are being 'connected', whereby all kinds of data can be retrieved from the IT systems of vehicles in real time. The advantages of this are: greater coverage, lower costs, more local information and new insights from sensors that were previously unavailable.

Exploration on Probe vehicle data

What data from vehicles is already available? And how can this data assist in carrying out public tasks in the areas of road safety, traffic management and asset management? What are possible applications? Which are the most promising? In the context of the Dutch collaboration agenda Smart Mobility, NDW has explored the possibilities of this new data source.


Ongoing project with probe vehicle data

The recommendations from this exploration were immediately followed up with a project. A number of road authorities, led by NDW and with the help of d-fine, have started to take a closer look at the vehicle data available via NDW, who serves as a national accesspoint ITS (European regulation). In the first project phase, road authorities want to understand the content and quality of the data, interpret them correctly and investigate possible use cases. This phase of the project is carried out in close collaboration with: Rijkswaterstaat, KNMI, the provinces of Overijssel, North and South Holland, the municipalities of Amsterdam, Utrecht and Zwolle and others.
The road authorities are assisted in this by consultancy agency d-fine, which helps with methods to standardize the message types of different car manufacturers, filter out incorrect and duplicate data, analyze and re-interpret / transform data into meaningful events, to provide useful output for the obtain road authorities.


First tests with vehicle data (summer 2020)
The next phase in the project has now arrived: we are going to test with the most promising use cases! We are happy to share our insights and experiences with you. If you would like to learn more about the potential and uses of vehicle data, please contact the project team at daan.arnoldussen{at} Or download the fact sheet at the bottom of this page for more information.


Which vehicle data is available via NDW
From 2021, vehicle manufacturers are obliged to inform the National Access Points (NDW for the Netherlands) which safety-related data from cars is available, and how this information can be made available. The OEMs are currently sharing the first versions of their data. NDW receives anonymized sensor event locations, including 'hard braking', 'ABS active' or 'quick wipe' (so-called level 2 data) and interpreted event types as 'slippery road' or 'accident' (so-called level 3 data) .By visualizing this event data on a map and integrating the data into daily practice, e.g. of the traffic center, road managers get a real-time overview of the situation on the roads.
