“Intelligent” asphalt with particular magnetic properties that could be particularly useful for so-called “electric scooters” was created by a group of scientists from the University of Granada. These new materials, used as street coverings, can change their properties depending on the presence of external magnetic fields.
According to the researchers who created them, they can signal to these small electric vehicles when they have to slow down and, in a more advanced view, they could even turn off the electric motor of the vehicle in case of danger. This new asphalt could help as regards the growing use of kinetic scooters and in cities, a use that is not yet regulated also because these vehicles are not very fast so they are not compared either to classic scooters, or to bicycles.
Moreover, the city infrastructure itself does not seem to be equipped to handle “vehicles” like these. The engineers of the University of Granada have developed “coded” asphalt which contains different amounts of metallic material. This metal material is composed of magnetic particles and can be incorporated into sensitive points such as the edges of sidewalks and pedestrian crossings.
Devices grafted under the asphalt can “be coded using metallic particles” and can send a code to the electric scooters. They can, for example, warn users to reduce speed or they can even trigger the engine to stop.
The project was presented at the EATA (European Asphalt Technology Association) eighth conference in Granada.
