Within the application fields of the MCA, transportation plays an important role. Specifically, there has been a flourishing literature investigating the assessment of SM, both ex-ante and ex-post at the urban scale and the city level, while the literature at the neighbourhood level is still poor. The literature on the city level presents the indicators to measure SM, and adopts the MCA to obtain the indicators weighting (see, among the others, [55]). Among the many works focusing on the city level, the PROPOLIS Report [56], the TRANSPLUS Report [57] and the PROSPECT Report [58] present some successful good practices connecting measures in land use and urban transport, and develop specific strategies and indicators to achieve SM. Specifically, the PROPOLIS Report aims at finding policies that could, in an ideal case, simultaneously improve all dimensions of sustainability compared with the reference solution and, if possible, even improve the current level of sustainability. Other applications of MCA are found in the work by Campos Gouvêa et al. [55], which proposes a set of mobility indicators with the objective to integrate transport and land use planning in order to achieve an efficient sustainable urban development. The case study analyzed by the authors is Belo Horizonte, the third largest city of Brazil. Besides, Tzeng et al. [59] adopt MCA to evaluate alternative-fuel buses in Taiwan urban areas; Yedla and Shrestha [60] focus on the selection of alternative options for environmentally sustainable transport system in Delhi.As stated above, the literature on MCA, carried out at neighbourhood level, is very scanty and usually refers to the ex-post perspective. At least to our knowledge, only the works by Cerreta [61], and Cerreta and Salzano [62] focus on the ex- post assessment of sustainability at neighbourhood level. This work originates from the “Best Practices and Local Leader- ship” programme developed by the UN-Habitat, which anal- yses, since 1996, the best urban renewal cases (for a detailed review, see Fusco Girard et al. [63]). The database contains about 1,700 ex-post evaluations, which have underlined that the best practices as concerns environmental, social and economic sustainability, have been characterised by the mutual investment in six different dimensions, belonging to the socalled Hexagon model [64]. The Hexagon model focuses on the integrated vision of sustainability, and is based on six different kind of capitals which are strongly interconnected (See Table 1).
