The disruptive innovation of e-commerce on incoming and outgoing flows has led to a marked increase in traffic volumes over the so-called last mile. This increase has inevitably impacted urban infrastructures ill prepared for such higher flows and related negative externalities. Moreover, fierce competition and ever more complex customer demand weigh on firms' logistic chains in the form of increased delivery charges and operational inefficiencies simply to preserve market share. This situation is likely to worsen as e-commerce continues to expand and uncertainty over Covid 19 persists. The last mile is a rapidly changing yet problematic link in the logistic chain since: - customers expect free and fast delivery;- logistic companies need to satisfy increasingly demanding customer delivery needs;- urban roads, already overloaded with flows of people and traditional goods, face significant increases in the size of these flows together with the rapid speed of change;- these complex changes are not a priority on policy makers' agenda. All these changes will transform the concept of the city. The purpose of this paper is to provide an updated overview of the current condition for urban deliveries as well as to analyse challenges and identify opportunities for future improvements. This paper reviews recent developments in e-commerce and the urban freight transport solutions used. Specifically, the work provides a complete overview of the critical factors affecting e-Commerce's last mile (failed deliveries, returns, packaging, role of customer satisfaction). The paper also highlights gaps in current research on the topic (i.e. data collection on load factors, externalities, warehousing space and related impacts) as well as within the political agenda (i.e. regulation for efficiency in delivery, planning of collection points and their accessibility, green urban policies, consumer environmental awareness).

The long-term efficiency of transport operator profit and the benefits for passengers conduce to opposite results. Actually, intervention by previous decision-makers to pursue one of the two goals generate opposite results on the other, forcing decision-makers to a difficult trade-off. The aim of this work is to provide a model that analyses, in an integrated perspective, operation and Service Policies (SPs), making an appropriate synthesis on both policies. This work proposes a cost-model formulation to optimize the merged operation and SPs to improve the current exploitation strategies according the service and maintenance activities. The proposed work is based on the following approaches : (i) a numerical model for the operation policy to determine the profit value of different working periods ; (ii) a stochastic process for the passenger flow that considers the uncertainty of passenger travel to compute the benefits according to their travel time ; and (iii) a cost-based optimization to bring together the operation and SPs. Finally, the proposed optimization model is applied to a massive urban ropeway operation of a public transportation system, in which the current SPs has been evaluated, considering the established transportation operation.

Urban Freight Transport (UFT) entails significant advantages for the economic growth of cities, but can also hamper population quality of life, obstructing vehicles and people movements while exacerbating environmental problems. Many initiatives have been engaged by many city administrators in order to efficiently manage UFT, evaluating different policies at a global scale. From the perspective of operators, most works analyze a limited set of policies or only focus on the benefits of companies. In this work, a decisionmaking process is used to evaluate a large set of UFT policies, through different attributes representing the advantages and limitations of each policy over promoter companies and the society. To do so, an ex-ante procedure in five steps is proposed to classify the policies: (1) attributes definition, (2) attributes weighting, (3) policy-attribute assessment, (4) policy ranking, and (5) feasibility threshold satisfaction. The whole process is supported on consultations to 26 experts regarding shop supply and restocking activities within complex urban environments. Results show a classification of the analyzed policies, according to their suitability for implementation ; which could be extended (directly or with small adjustments) to other contexts, given the flexibility of the decision-making procedure developed.
