Análise da situação de trabalho do motorista em uma empresa de ônibus urbano da idade de Natal (RN)

The problem dealt with in this study concerns the analysis of bus drivers' working situation. It stemmed from the need to identify the difficulties faced by these professionals in accomplishing the results expected by the company. A case study was carried out in a public transportation company in the city of Natal. Records and observations made in the workplace, alongside perfomance indicators, such as absenteeism tax, staff turnover and traffic accidents, revealed problems in their activity. It was made clear that, in the company being studied, absenteeism was related to health problems, particularly psychiatric and musculoskeletal disorders, and that although the indicators of traffic accidents and staff turnover have declined over the years, they are still elevated. The interviews involved 50 of the 124 drivers who worked directly in the service, and contained questions covering eleven factors related to the drivers' work. They indicated a gap between the prescribed work and the work actually done, in that there were a series of embarassing or stressful situations involving traffic, itinerary length, road conditions, vehicle maintenance, physical environment (bus terminus), job post and supervision policies. On the other hand, factors such as enjoying driving, the work itself and being with workmates positively influenced the drivers' working conditions. In the propositions of the administration and human resources subsystems, some alternatives were found in order to remodel this activity

Uso urbano não potável de água de lagoas do sistema de drenagem de Natal

The detention and infiltration ponds of urban drainage system has function to protect the population from undesirable effects of floods. In general these ponds are not completly used and it potential is wasted. As it are disseminated at different places at cities it can reduce costs with water transport and permit water preservation of best quality. Some it utilities includes use in green areas irrigation, industrial among than cooling towers and boiler, soil compaction, cleaning urban road, pisciculture and fire fighting system. The quality these water is influenced by anauthorized sewage in the drainage system. This study was performed in six detention and infiltration ponds at drainage system of Natal, which aim was to verify the non-portable use these ponds on urban environment. As indirect aim would to incentive the water utilization these ponds as a water source to another uses in urban environment. These ponds represents the characteristics of detention and infiltration of Natal city and consequently of Brazil. As the water quality, the ponds presents following characteristics: three has apparently good quality, other showed intermediate condition and two had water polluted. Were performed twenty sample in each ponds and the following parameters assessed: pH, temperature, dissolved oxygen, turbidity, electrical conductivity, coliform thermotolerant, ammonia, organic nitrogen, TKN, nitrate, total phosphorus and alkalinity, bicarbonate, chloride, total hardness, calcium and magnesium hardness, total solids, TSS, TDS, COD and SAR°. To utilization on pisciculture we recommend use in ponds which presents the best quality. Only one pond presented higher pollutants and it not being appropriated for use in cooling tower. The content of solids suspension restricted the water use in all ponds in boilers. As water use in soil compaction, cleaning urban road and fire fighting system the water from these ponds are not appropriated. However, the recommended limits from literature are to domestic sewage, due to this, the parameters are restrictive to diminish the sanitary risk that could be offered with it utilization. The infiltration velocity of water these assessed ponds restrict a moderato use, however the effects are potentiated only in soil less sandy, which not occur in Natal. It is recommend the unrestricted irrigation utilization in ponds with best quality of water, and a restricted irrigation to ponds with worst quality of water. As load of pollutants, it is recommended a complementary treatment in those ponds whit higher load to diminish sanitary risks. In only one pond was found one helminth eggs and due to the convention formula of results, it was found for all ponds less than 1 helminth/liter eggs.

Análise da salubridade do meio urbano com base na utilização de índices ambientais: aplicação na bacia de drenagem XII da cidade do Natal-RN

The growing accumulation of people in urban centers caused chronic problems of the cities to begin to take an increasingly unsustainable. Primarily related to lack of infrastructure coupled with sanitation and lack of investment in critical sectors such as health, education, housing and transportation, these problems start to deteriorate markedly the quality of life of city dwellers and put into test management policies of the spaces urbanized. To reverse this situation, shows is essential to the use of tools (highlighting this harvest rates and environmental indicators) that help in assessing the current conditions and may assist in predicting future scenarios. From the information listed above, now put the research seeks to present an index called ISBA Environmental (Sanitation Index) which looks at the four urban systems (water, sewer, solid waste and urban drainage) from the viewpoint of application in a geographical cutout specific - in this case the Drainage Basin XII, defined by the Plan of Urban Drainage Stormwater in the city of Natal, capital of Rio Grande do Norte. This index, together with analysis of other factors sought to trace the current conditions of the basin and thus, assist in proposing the best solutions. For the preparation of the index was applied a questionnaire with a sample of 384 (three hundred eighty-four) households that aimed to study two variables: access to services and satisfaction of the population in relation to these. The ISBA has shown that the system is the most deficient collection and disposal of effluents (ICE = 47.66%), followed by the drainage of rainwater (IDAP = 54.17%), water supply (AAI = 61, 36) and solid waste collection (IRS = 78.28). With the ISBA was possible to verify that the qualitative data shows whose subjectivity is evident (as is the case of user satisfaction) can be of great importance when an assessment, since we obtained the correlation coefficient between the variables "Access" and " Satisfaction "equal to 0.8234, showing a strong correlation between the existence / quality of service offered and the impressions of the population that receives them

A redefinição do espaço urbano de Natal/RN a partir da influência dos serviços: uma análise das avenidas Bernardo Vieira e Engenheiro Roberto Freire

This paper analyzes the influence of trade and services in the reconfiguration of urban space in Natal, with the Avenues Bernardo Vieira end Roberto Freire Engineer as privileged analysis. Initially, we discussed the concepts of production and reproduction of urban space, urban centralities, decentralized, services and public policies, especially transport and tourism. Then, we show the construction of urban space from Natal, highlighting the historical formation of the districts of Ribeira, Cidade Alta and Alecrim, pioneers in the service sector, noting that currently there is an ongoing process of decentralization in the city of such activities, to other areas of the urban fabric of Natal. Later, we studied the Avenues Bernardo Vieira to Roberto Freire Engineer, noting, in both the distribution of commercial activities and services, and issues related to transportation, traffic, tourism and socio-economic problems, identified them. Finally, testify that Natal, from the 1980s, underwent a process of decentralization of services, both to the south, and north of the city on the ball. In this process of decentralization we ascertain the role of public policies on transport and tourism, complementing the action of private enterprise, through the real estate market, on Avenue Roberto Freire Engineer.

Território usado e transporte coletivo : mobilidade e acessibilidade no Bairro Lagoa Azul Natal/RN

Transport systems involved the use of territory in different Brazilian cities with regard to the occupation of road systems in urban areas. The implementation of systems engineering and transport infrastructure such as roads (roads), signs, stops, stations and complex road (bridges, viaducts and tunnels) are not used in the same way in the area. The subway is not even use the bus and vice versa. The time spent in travel, the time to access and the number of trips made by passengers in each way of transport is not the same. The use of transport systems in the territory, therefore, takes place through a whole in the current period we are in the technicalscientific and informational. This work addresses, however, the area used as a synonym of geographical area, analyzed by two categories of analysis, systems of objects formed by the fixed and the systems formed by the action flows. The system analyzed is the public transport by bus and population displacement that makes using this medium with source destination from home to work and has as empirical cut the Lagoa Azul located in the district administrative area north of Natal / RN. The general objective of this research is to understand the extent to which public transport has contributed to the socio-spatial accessibility of the residents of Barrio Blue Lagoon, located in Natal-RN, emphasizing the way home and the workplace. To reach the general objective of this dissertation, a study was made in light of the line which the methodological empirical facts, statistical data and theoretical knowledge of the events that occur in the quarter related to the Lagoa Azul economic aspects. Use for this, the concepts of mobility and Accessibility

Congestión del tránsito urbano: alternativas para su control

La congestión de tránsito no es un fenómeno nuevo en las ciudades latinoamericanas, pero se ha agudizado en los años recientes. No conviene eliminarla sino reducirla. Para muchos economistas y planificadores del transporte, la tarificación vial por medios electrónicos representa la mejor alternativa, ya que hoy existe una tecnología adecuada para su implementación, pero la experiencia revela que debido a consideraciones de orden político, conviene más comenzar a enfrentar la congestión del tránsito urbano con medidas de control más sencillas. Como punto de partida en el corto plazo, una tarificación vial sencilla pareciera ser la alternativa más atractiva; por otra parte, las experiencias de Londres, durante más de 20 años, y de Santiago de Chile, por más de seis años, señalan la presencia de obstáculos sociopolíticos hacia la aplicación de esta opción. Hay más apoyo político para las medidas de control de estacionamientos, cuya explicación, en parte, reside en que las autoridades competentes carecen de facultades para restringir la cantidad de estacionamientos disponibles a automovilistas de ingresos elevados e influyentes, quienes contando con estacionamientos en las cercanías de sus oficinas, provocan gran parte de la congestión. En América Latina, la propensión al uso de los taxis también reduce la eficiencia de las medidas dirigidas a los estacionamientos, porque los taxis congestionan, pero no se estacionan.En suma, el problema de la congestión no se resuelve tomando medidas inocuas. El momento ha llegado para adoptar políticas más audaces; es decir, medidas que al menos ejerzan control sobre los estacionamientos que hasta ahora han quedado fuera del alcance de las autoridades y, preferentemente, adoptar sistemas sencillos de tarificación vial.

Tecnologías aplicadas al transporte: sistemas de cobro electrónico

A pesar del desplome de muchas empresas puntocom y de la poca penetración del comercio electrónico en la región, las transacciones electrónicas son cada vez más frecuentes en los países de América Latina y el Caribe. En el ámbito del transporte, la incorporación paulatina de la tecnología para apoyar los procesos y el intercambio de flujos monetarios entre los participantes, ha permitido otorgarles una mayor versatilidad, seguridad y flexibilidad. En el transporte público, estas iniciativas se concentran en los cobradores automáticos y dispensadores de tarjetas de prepago. En el tránsito urbano, en los monederos electrónicos para el control y pago del tiempo de estacionamiento, en tarificación vial, los telepeajes permiten otorgar mayor agilidad al proceso de recaudación, especialmente en las autopistas y concesiones urbanas. En el transporte marítimo, cada día son más frecuentes las transferencias electrónicas para el pago de importes aduaneros y derechos portuarios.Dada la importancia y el interés que concita este tema, la Unidad de Transporte ha comenzado el estudio de estas materias, publicando recientemente el documento Sistemas de cobro electrónico de pasajes en el transporte público, LC/L.1752-P/E, Julio de 2002, sobre el cual se basa la presente edición del boletín.
