Intensive cargo movement in urban areas generates many vehicles in city centers. As a result, there are congestions increase and intensification of freight transport distribution system challenges. To overcome the difficulties, local traffic rules and restrictions for heavy vehicles are established, but they have an impact on carriers and shopkeepers activities, parcel little heard by surveys. The purpose of this paper is to analyze the difficulties in the receipt of goods in Niterói center, under the view of retailers. The data collected by survey in the study were evaluated trough descriptive statistics and multivariate analysis. The major impasses found were the lack of available places for unloading and intense traffic, and for logistical challenges non-opening to overnight delivery and security level in the receiving periods, due to the urban violence.

Airport concessions to private management began in Brazil in 2011 to address infrastructure bottlenecks and the need for investments. Productivity improvements after privatization need to be measured and efficiency gains can help to identify strategic points where to intervene both in current and upcoming concessions. However, previous studies have applied neither the Slacks-Based Measure Data Analysis Envelopment models nor the second stage Tobit regression to evaluate airport efficiency, especially in the context of Brazilian airport privatization. The objective of this study is to verify if privatization contributes to improving Brazilian airports' productive efficiency compared with public airports, using variable slacks and identifying new socio-economic variables that may influence the productive efficiency index. A two-stage SBM-DEA approach found that only 40% of the sample among 28 airports are efficient, evidencing poor management overall, and the slacks show the sectors that need most attention and investments. Based on the productive process and the sample evaluated, the study concludes that privatization of Brazilian airports did not improve their production efficiency. A revision of the contracts in the first round of concessions is suggested, as contractual obligation may result in lower production efficiency.
