    Property and values: the affordability, accessibility, and autonomy of collaborative housing

    Not all approaches to collaborative housing deliver equally on affordability, accessibility, and autonomy. Some cases may become expensive or enclaved, while others that are accessible and affordable may have little collaboration. This paper compares eight cases of collaborative housing in Milan and Amsterdam to understand how collaboration projects deal with demands for affordability, accessibility, and autonomy. We identify four categories of collaborative housing—common, self-promoted, co-managed, and developer-led—along the two axes of tenure type and project initiator. Trade-offs in affordability, accessibility, and autonomy always persist; however, each can be fostered by three of the types (all but developer-led) when explicitly established as core values of the project

    Marginal Activity Access Cost (MAAC): a new indicator for sustainable Land Use/Transport (LUT) planning

    Get PDF
    The paper presents the ‘Marginal Activity Access Cost’, an accessibility indicator providing estimation in monetary terms of the impacts on mobility and on the environment of locating a single new activity in a specific zone of the urban area. In the first part of this paper, the new indicator is presented and compared to other accessibility indicators proposed in literature. In the second part, the MAAC is validated through an application to the urban area of Rome. The paper concludes with brief remarks on using the proposed accessibility indicator as index of performance for sustainable spatial planning

    Changing accessibility, dwelling price and the spatial distribution of socio-economic activities

    In this paper we present an activities location choice model with endogenous price which simulate, based on Expected Random Utility principle, the behavior of several agents of the urban system (i.e. the workers distinguished by income, the firms by economic sector) to estimate the spatial distribution of socioeconomic activities within the study area as well as the impact of differentiated changing accessibility on the dwellings price. The study area for this research is the metropolitan area of Napoli (South-Italy), for which we show the results of the model estimation and the results of a “backcasting” application to future transportation scenarios

    A feasible algorithm for typing in Elementary Affine Logic

    Full text link
    We give a new type inference algorithm for typing lambda-terms in Elementary Affine Logic (EAL), which is motivated by applications to complexity and optimal reduction. Following previous references on this topic, the variant of EAL type system we consider (denoted EAL*) is a variant without sharing and without polymorphism. Our algorithm improves over the ones already known in that it offers a better complexity bound: if a simple type derivation for the term t is given our algorithm performs EAL* type inference in polynomial time.Comment: 20 page

    Accessibility and socioeconomic activities location

    Get PDF
    This paper aims at analyzing to what extent changing accessibility affects the distribution of residential and economic activities in a region. The study is carried out by mean of empirical and modeling analyses. The case study is that of the Regione Campania, one of the 20 administrative regions of Italy. The empirical study consists of before-and-after analyses correlating the variation of zone accessibility to the variation of population and other economic activities (Commerce, services, etc) over a 20 years long period. The results of the analyses carried on show that the impact of accessibility on the location of certain economic sectors is negligible (e.g. for Public services, Wholesale), while it is significant for Residents, Retail, Private Services location. In the latter case, however, it is evident that there are other factors affecting such location choice even stronger than accessibility (e.g. housing prices, congestion of the urban system, and so on). In order to deeper investigate such issues, an integrated modelling framework simulating land-use and transport interaction is proposed. The results of the aggregated calibration of the model parameters are presented and discussed in the paper
