This paper concerns the results from the questionnaire-based investigation of the impact of the pedestrianisation of the historical center of Athens to the delivery system of the shops.  More precisely, a combined analysis of the types of vehicles used, the delivery demand characteristics (number of trips, hours, shop size), different road types, as well as the traffic and parking problems of the commercial vehicles.  This investigation has led to the detailed identification of the pedestrianisation impact, which on the contrary of what was expected, seems to be limited for most of the cases.  Finally, the role of commercial vehicle fleet in delivery restriction schemes in central urban areas has been identified.
