Planning with stakeholders: Analysing alternative off-hour delivery solutions via an interactive multi-criteria approach.

Many cities of different size and in different areas of the world have successfully tested the introduction of off-hour deliveries (OHD) on a voluntary basis, reporting positive effects, both on freight distribution efficiency and sustainability. However, those initiatives have not been implemented so far at a large scale. This paper investigates OHD potential in Rome, focusing on one of the most important barriers to its adoption, i.e. stakeholder acceptability. The study investigates stakeholders' preferences for different OHD configurations using both a qualitative approach, based on in-depth interviews, and a quantitative analysis, based on an interactive multi-actor multi-criteria analysis. Results show that stakeholders prefer a solution where OHD are jointly implemented together with one or more urban consolidation centres. This preliminary analysis paves the way for further technical/economic evaluations needed for OHD implementation in Rome. Stakeholders' involvement is of outmost importance to understand their heterogeneous preferences and increase their awareness of urban freight transport problems, with the overall aim to foster behaviour change.
