One of the main challenges in urban logistic is the collaborated handling of freight transportation and urban public transport. Especially during peak periods, e.g. when commuters travel between their place of residence and place of work, the urban infrastructure for car traffic and public transport risks to collapse. In addition, often the freight transportation in urban areas competes with the public transport because of the use of the same road infrastructure. Therefore, it would make sense also to use free capacities of public transportations like trams for freight transports. First, this paper analyzes current concepts of urban logistics and concepts for the use of freight trams. Second, a new approach for the use of autonomous trolleys combined with the use of public trams will be introduced by the authors.
