Shopping attitudes and urban freight distribution: the effects of demographic changes

摘要: Studies of urban freight mobility traditionally focused only on restocking flows, i.e. vehicle flows from warehouse/distribution centers to trade or service locations (e.g. shops, food-and-drink outlets, activities). They usually neglected the linkage with shopping activities even if end-consumers’ characteristics and choices in relation type retail small, medium large) undoubtedly impact distribution flows. In fact, process are strictly related commercial be restocked terms delivery size, frequency, so on. Further, segment passenger received few attention respect systematic components home work trips) weight that it has areas. For example, some French cities, was estimated represents about 69% distances (veh-km) covered each day by motorized vehicles. Besides, been studied as a component demand mainly investigating relationships between travel behavior, built environment land-use profile, activity density) socio-economic characteristics. Few studies have analyzed perspective distribution. Moreover, although store remains predominant way buy, internet is modifying end consumer’s behavior. this case, commodity can transported place consumption actors other than user. USA e-commerce sales represent 5.5% Retail Sales, according surveys carried out Rome, 13 % interviewees stated they did e-shopping during survey week. This confirms becoming diffuse among youngers future could modify in-depth purchasers’ behaviors. Therefore, paper discusses number issues transportation impacts attitudes distribution. particular, focuses factors influence distribution: quantity (including e-shop). After an analysis state-of-the-art modeling, models for simulating choice outlet presented. The were obtained using where more 500 families interviewed. The models, jointly used order assess effects scenarios relative inhabitants location restocking. Then, results reported discussed full paper.
