Bimodal synchronized transportation for inner city freight deliveries

Beschreibung

Increasing urbanization combined with the looming threats of climate change constitute the current challenges in city logistics. Supplying citizens with all necessary goods without deteriorating the quality of life is difficult to accomplish. Therefore, we investigate the use of a more sustainable mode of transport, cargo bikes, in inner city delivery. We develop a two echelon routing scheme with synchronization of vans and cargo bikes. In our model the city is divided into three zones: the city center, the outer districts, and the so-called 'grey zone' marking the border between the city center and the outer districts. We investigate two different distribution policies and evaluate them according to the objective function comprising economic costs, emission costs and social costs, such as nuisance or traffic jam. The first policy is to assign all customers in the city center to cargo bikes and all customers in the outer-city districts to vans. In the second policy customers located in the 'grey zone' can be assigned either to vans or to cargo bikes while fulfilling all customer requests. A combination of heuristic and exact methods is used to solve this NP-hard problem. We are going to present preliminary results for a test instance from Vienna comparing the different distribution policies. These results illustrate the various kinds of costs and can therefore give planners a decision support in using such a more sustainable kind of freight distribution in a city
