IP0078 - Aggregation of connected vehicle tire-road friction data for monthly winter road maintenance follow-up reports
In a more connected world, vehicles are producing more data than ever before. The concept of cars and other vehicles being connected to and deliver data to a central hub is commonly known as connected vehicle (CV) technology or floating car data (FCD). Modern cars can produce estimations of tire-road friction (TRF) using standard sensor systems and combined with CV technology, these measurements can [...]

IP0276 - Digital Winter Road Information for Resilient and Efficient Municipal Winter Road Maintenance
Today's municipal winter road maintenance is often planned and executed using inadequate data and system support, leading to high costs, inefficient resource use, and negative consequences for the working environment. With increasing digitalisation, the accessibility of infrastructure-related information has become faster, more cost-effective, and widely available, creating opportunities to develop [...]

IP0358 - Digitalization of winter maintenance in the Bratislava region
The Road Administration of the Bratislava Self-Governing Region carries out complex administration and maintenance of road infrastructure through its own capacities and mechanisms at the regional level within the Bratislava Region, which represents the smallest administrative unit within the Slovak Republic, but with the highest intensity of traffic movement, especially in the vicinity of the capital [...]

IP0329 - Estimation of Visibility Information at High Spatial and Temporal Resolution by Combining Visibility Measured by CCTV Cameras and On-board Video Cameras in Winter.
In Hokkaido, Japan, poor visibility caused by snowstorm can lead to a disaster that could affect human lives, such as multiple collisions, multiple vehicles stuck, and so on. With detailed road visibility information, the road users and the road administrators can prevent these serious incidents due to snowstorms in winter. However, it is not easy for the road users and the road administrators to [...]

IP0064 - Evaluating suppliers of connected vehicle data for follow-up tire-road friction wintertime – A field test
Since 2019, the Swedish Transport Administration (STA) has been acquiring information on tire-road friction (TRF) using data from connected vehicles (CV) to improve winter road maintenance. By increasing knowledge of the surface of the road, and more specifically the interaction between the tire and the road, the aim is to create safer roads in line with Vision Zero. Improved winter road maintenance [...]

IP0043 - Introducing the "digital tunnel"
The recording of GPS positions for each pole precisely defines the roadsides for all roads operated by RoadTech snow pole robot. By interpolating GPS-positions, RoadTech is calculating and establishing complete sets of data for each road stretch, creating a virtual, “digital tunnel”. Based on this set of GPS-data, RoadTech has developed applications for the snow plough truck driver for assistant [...]

IP0277 - Shared Road Condition Data for Reliable Bus Services
The project ‘Shared road condition data for reliable bus services’, aims to improve public transport reliability through the use of real-time data on the condition of the road infrastructure and improved road condition forecasts to improve winter road maintenance. The project, which was a demonstration project that ran from September 2022 to January 2025, focused on bus traffic in the city of [...]
