LIVE SHOW NEWS: NIRA Dynamics aggregates existing road surface data with weather data for better V2I coverage

NIRA Dynamics (Stand AV6020), which has been collecting road surface data from cars in the Gothenburg, Sweden, area to generate maps on road conditions, is expanding its offering with additional weather data for more accurate monitoring and predictions of road conditions.

The company installs its software in cars, to collect data from the wheel speed sensors to gather data on road friction. This data will now be combined with detailed road weather data from Klimator, based at the University of Gothenburg, which provides information about the topology of the road, whether there is shadow on the road at a certain time of day, the surface temperature, how wet the road is, etc. The combination of all these sources makes it possible to predict how the road friction will change over time.

The aggregation of all the data means that the software is now also able to extrapolate the conditions for smaller roads, where there is less data available.

Johan Hägg, head of marketing and sales at NIRA Dynamics, said, “Since we don’t have data from all the small roads, we can look at the areas where we do have data, what the road weather data looks like, and then estimate what it is going to be like on smaller roads similar to those areas.”

The technology is based on a series of algorithms that the company has had for a while, but that it couldn’t make a product from at the time.

“In 2014, we really started developing it. It has been under development for many years, but we needed a lot of test data to be able to put these algorithms to use,” continued Hägg. “An unconnected version of the software will be on the market from 2020, but for the connected features, with full coverage in Europe, we estimate 2024. We will start to roll out connected features in 2021.

“We see AV manufacturers as our potential customers, but any vehicle manufacturer as a data supplier. We work on a revenue-share based model, where vehicle manufacturers let us install software in their cars, they send the data to us and they get part of the revenue when we start to sell the software. This is quite a new way to do business for car manufacturers.”
