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.
