Reverse logistics and space allocation for recovery management in new urban settlements

This paper presents the authors’ vision about the planning foundation for the new residential areas from the large cities outskirts, in a sustainable development framework. One considers the great generation potential of the high and very high income population in case of the used products with remained reuse value, or new and undesired products, available in the residential places. We propose a space allocation model with a hexagonal hierarchical structure for the centralized return centers in a reverse logistics. The space allocation model for the recovery centers implementation takes into consideration: the recovery habits, environmental care and sustainable development education, “moral” compensations, centralized recovery centers facilities, walking willingness of the average inhabitant of the considered area, decision makings involvement at the local Public Authority level, and local community. One reveals the importance of the data collecting stage for the potential and availability of the exhausted products (having reuse value) in a specific area with high and very high income populationreverse logistics; centralized return centres; recovery potential; space allocation

NON-MOTORIZED TRANSPORTATION – AN EDUCATIONAL CHALLENGE FOR URBAN COMMUNITIES

The continuous growth of the urban traffic threats cities with “thrombosis“, generating social, economic and ecological long term problems. The paper outlines the positive externalities induced by the non-motorized transportation (walking, bicycling or small-wheeled transport) at individual, social and environmental level. This kind of transportation meets the requests of the urban sustainable development, being used stand-alone or as a part of an intermodal chain. Local authorities, education institutes, corporate and non-governmental organizations should be involved in challenging perceptions and attitudes toward non-motorized trips. Beside the infrastructure construction, the early education is mandatory for creating a civic culture regarding the use of non-motorized transportation. The case study in Bucharest shows out the present state concerning the use of non-motorized transportation and the barriers in using it.urban mobility, non-motorized transportation, sustainable transport barriers.

Decisions of hypermarkets location in dense urban area – effects on streets network congestion in the Bucharest case

The paper represents some partial results of the research carried out by the Transportation, Traffic and Logistics Department - University POLITEHNICA of Bucharest, funded by the Romanian Ministry of Research and Education through the National University Research Council. In this paper we provide: a brief description of the interrelation between the life style changes of Romanian people during the last decades and the car traffic congestion in large cities; the streets network modelling of a radial-circular urban structure (the characteristic of a historically developed city as Bucharest city is), in case of car traffic congestion; the assessment model of the additional car traffic congestion for certain locations with large attractivity. Having an important effect on the entire lifestyle of urban people, the decision of a hypermarket location might be a complex one, taking into consideration the new leisure and shopping tendencies but also the additional car traffic congestion caused by the chosen location

Quality of life in Romanian patients with schizophrenia based on gender, type of schizophrenia, therapeutic approach, and family history

The low quality of life of patients with schizophrenia has been extensively discussed and investigated. Various aspects from gender, socio-demographic profile, and/or type of neuroleptic treatment have been taken into account in describing this condition. The purpose of this study is to assess the perceived quality of life of Romanian patients suffering from schizophrenia and to correlate it with gender differences, type of schizophrenia, family history of psychiatric illness, and type of antipsychotic treatment. 143 patients diagnosed with schizophrenia according to DSM IV-TR and ICD 10 were included in the study. Social demographic data were documented and further assessment was performed using the Subjective Well Being under Neuroleptic Treatment Scale –the short form (SWN-S) and the short version of the WHO- Questionnaire for The Quality of Life (WHO-QoL-BREF). The mental functioning dimension was higher in men than women; the social integration dimension was higher for the residual type of schizophrenia. Emotional regulation and the capacity of social integration did not show significant differences between patients who had a family history of mental illness and those who did not. Levels of self-control and physical functioning were better for patients treated with atypical antipsychotics and who did not report a family history of psychiatric illness. All five dimensions of the SWN-S were higher in patients treated with atypical antipsychotics, compared to those who were treated with typical antipsychotics. The study showed that for people with schizophrenia mental functioning was better preserved in men, in patients who did not have a family history of psychiatric illness, and in patients who were treated with atypical antipsychotics. The level of social integration was better in patients who were treated with atypical antipsychotics but this effect depended on the type of schizophrenia

Influence of the freight transnational rail liner service on the train scheduling in case of major corridors

In this paper we discuss several consequences of the freight transnational rail liner service on the rail corridor capacity. The Northern part of the IVth TEN-T corridor on Romanian territory has specific feature related to the passenger flows connecting important Romanian demographic and economic clusters, on one side, and on the other side, to its diagonal crossing aspect, from the Western border to the Constanta port, connecting the Central Europe countries to the Black Sea regions, which means that there are a lot of expectation in terms of this corridor rail capacity: this corridor will, be for a long time further, the single and first completed continuous upgraded and modernised rail corridor. Its utilization will necessarily be heterogeneously planned (meaning for passengers rapid trains and freight rapid trains, from domestic/internal market, but especially for external market of Romania). In this paper, we consider a simple mathematical model for the calculus of capacity in two different cases: for a homogeneous utilization, meaning that all trains have the same running speeds and for heterogeneous utilization, when the passenger trains have the higher speed and hence, the higher priority over the freight trains, even if some of them are freight transnational liner service. Special feature of liner rail service has to be considered (fixed schedule, no stops for passenger train advance). We draw several useful possible solutions to be considered in order to preserve the active corridor capacity, and to assure a smooth flow for the transnational liner services, which ultimately will enhance the rail attractiveness

On transport network reliability

Transport network reliability is defined in relation with the main attributes of the network (e.g. connectivity, topology, state of infrastructure), the traffic characteristics (OD matrices, volume, hourly/day-to-day variations etc.) and with environment interactions (natural event, climatic change). The study of the Romanian national transport network reliability in terms of economic implications, like the growth of the total traveled path induced by functionality/failure of the network components leads to the identification of the road links which, according to the reliability, should be carefully monitored to preserve the attractiveness of the transport network. Using Visum software, the paper presents a methodology to assess the transport network reliability at national level but also useful for urban transport networks

Modeling the transit of containers through quay buffer storage zone in maritime terminals

The maritime container terminal allows the transfer of container flows from maritime vessels to the land transport network and vice versa. The transit capacity through the terminal is affected by the handling capacity of the equipment at the terminal, by the size of the storage areas and least by the technologies used in handling and storing the containers in the terminal. In this paper, the influence of these last two technologies on the duration of the process of unloading/loading of sea vessels within the terminal is analyzed. A discrete simulation model is used to evaluate the sizing method for short-term storage area located on the dock. The manner of allocating the flows of containers on it, as well as the working technology of the handling equipment, have an influence on the number of containers taken over, respectively loaded on the maritime vessels. The simulation model topology is developed following the existing physical structure of a container terminal from Constanta Port, in Romania. The obtained results can help the administration of the container terminal in optimizing the activity of handling, storing, and transferring the flows of containers from the maritime environment to the mainland and vice versa
