Prediction of road accident severity using the ordered probit model

The ordered probit model is used to examine the contribution of several factors to the injury severity faced by motor-vehicle occupants involved in road accidents. The estimated results suggest that motor-vehicle occupants travelling in light-vehicles, at two-way roads, and on dry road surfaces tend to suffer more severe injuries than those who travel in heavy-vehicles, at one-way roads, and on wet road surfaces. Additionally, the driver's seat is clearly the safest seating position, urban areas seem to originate less serious accidents than rural areas, and women tend to be more likely to suffer serious or fatal injuries than men

Shrinking the plan. A middle-class wishful thinking in the outskirts of Lisbon

In the 1960s and 1970s, large-scale Portuguese architectural production was largely promoted by the State. This took further aspects after the 1974 revolution when housing construction became one of the pillars of the new state policy. It is in this context that Manuel Vicente develops the project for Quinta do Bacalhau in different times: 1– Before 1974 by EPUL as part of UNOR 26 of which M. Vicente was the coordinator, 2– From 1974 as a SAAL operation after the site was taken over by a residents' committee, 3– After 1976, as it was built outside the revolutionary period by a housing cooperative and financed by the state. Unlike most SAAL projects – small, contained and with low-row houses –, and despite the ideologically marked circumstances of this period, it presents somehow ostentatious. Volumes of broad and generous features, incorporation of commerce on the ground floors like a boulevard, contrast with the dominant model, thus raising some questions: – to what extent did a particular class position correspond to a certain typology, style, etc.? – wouldn't this imply an aspiration to the same “rights” as the middle-class, as far as architecture is concerned? M. Vicente remains throughout his life in an ideologically multifaceted position. Close to the Communist Party, he has a cosmopolitan experience still in the 1960s being in touch with the Western capitalism – in the United States and in Macao – and in close contact with the speculation and profit markets. It has thus a double folded stance regarding the state-sponsored housing and low standards one, as if responding to the residents were the same as responding to himself. In this communication we intend to analyse through drawings of the project how the notion of housing for “a middle-class” crossed through the project. This argument is revealed in a plan of a dwelling with dimensions close to middle-class, which is later reduced to smaller areas, but “keeping” architectural qualities.info:eu-repo/semantics/publishedVersio

Generation of road accident risk maps

http://citta-conference.fe.up.pt/editions/2013Knowing the factors that affect the likelihood of an accident occurrence has been increasingly challenging to the researchers given the huge social and financial costs that derive from road accidents. In Portugal, developments in this area have mainly involved interurban roads studies. However, according to ANSRi, about 70% of Portuguese road accidents occur in urban spaces, a trend common to most European countries. The lack of national or local information systems containing geo-referenced road accidents, geometric characteristics of roads, among others, hamper the creation of tools that help to assess the risk of exposure at a micro level, i.e. road intersections. The weaknesses mentioned above led us towards the implementation of models in a GIS-based environment in order to estimate the frequency of accidents for urban areas according to several breakdowns: road element, type of accident and the inclusion of explanatory variables related to road environment. One of the challenges faced by researchers when applying these models is the absence of data or its poor quality. Therefore, it is necessary to cross and analyse information from different sources, such as traffic variables (from model transportation planning), digital cartographic data, and other geometric variables, that may not be obtained in a direct way (e.g. using OpenStreetMap or Google Maps). In a further step, the estimation models will be programmed and applied according to the type of road element (e.g. intersections, roundabouts, segments). Finally, new information will be generated with all inputted data: a digital map with the number of accidents per road element. Such figures will need to be converted into something more meaningful for potential users, such as levels/categories (e.g. high, medium and low risk of exposure), which can be mapped. This paper proposes a methodology for automatic generation of road accident maps with those levels/categories. Thus, maps will serve as a decision support tool not only to insurers (who are likely to tax drivers more effectively, according to their exposure to risk), but also to drivers themselves (through generation of alarms that will allow them to tailor their driving performance), envisaging road safety improvement

Performance evaluation of non-conventional constructions: case study in a temperate climate

The development of new construction solutions is fundamental to enhance the building stock energy performance, and thus promote sustainable development in the building sector. These solutions must be sensitive to both the energy performance and the environmental performance. The aim of the work presented in this paper is the comparison, in terms of energy performance, between heavyweight conventional solutions and mixed-weight non-conventional envelope solutions. These solutions were applied in a test building built at the University of Minho’s Azurém campus. The evaluation was carried out by means of data analysis of in situ measurements, and also the use of energy and daylighting simulation tools. Prior to the simulations, it was necessary to calibrate the model and create a weather file representative of the real weather conditions. From this evaluation, it was possible to assess the potentialities of different construction solutions. The non-conventional solution presented a similar energy performance but a better environmental performance than the conventional solution, due to the use of low embodied energy materials. It was also proved that, with minor modifications, the non-conventional solution can produce a better energy performance than the conventional one, evidencing the potential of application of these solutions

Water requirement and yield of fig trees under different drip irrigation management.

This work aimed to study the effect of drip irrigation management on growth and yield of the 'Roxo de Valinhos' fig tree (Ficus carica L.), at three years old, and to determine crop coefficients (Kc) and its water requirement (ETc) under Baixada Fluminense climate and soil conditions, state of Rio de Janeiro, Brazil. The study was carried out in the experimental area of SIPA (Sistema Integrado de Produção Agroecológica) in Seropédica, Rio de Janeiro State, from July 2011 to May 2012. The experimental area was divided in two blocks, named B1 (sandy clay loam texture) and B2 (loamy sand texture). In each block, irrigation frequencies (IF) of two (T1) and four days (T2) were evaluated, as well as the irrigation absence (T3). Irrigation management and water consumption determination were performed through the soil water balance, using the TDR technique. Plant growth was not affected by IF, differing only in the number of produced internodes. For both soil textures, the mean Kc was 0.60, with a significant difference (p<0.05) only for IF. The estimated mean yield showed no significant differences between both textural classes, ranging from 6,612 kg ha-1 (T3) to 8,554 kg ha-1 (T1). This study indicates the importance of irrigation frequency in the irrigation management of fig trees cultivated in soils with different physical characteristics
