Salt spreading has to be learned. Thousands of tons of road salt, which saves lives and is important for mobility in winter but is harmful to the environment, are wasted. Based on the GPS-assisted gritting services in use primarily in Hesse, a process that avoids this waste was awarded a prize at the ESNC. The "Streufuchs" cleverly relies on data mining and swarm intelligence. Congratulations to Erich Franke from AFUSOFT GmbH in Königsbach-Stein!
