Silke Höhl is a PhD student at the Research Lab for Urban Transport (ReLUT) at the Frankfurt University of Applied Sciences. The construction and industrial engineer won the « Best Idea 2019 » competition at the Allianz Pro Schiene Innovation Award 2019. Her concept: an innovative parcel delivery service. Hereby, the idea is not to create a new transport infrastructure, but to use public transport that is already well developed in the cities. The idea: underground and tramways take care of transporting the parcels to the city centres and a load wheel takes care of the last few kilometres to the front door.
