São Paulo has 22 million in its metropolitan area. It is served by Congonhas (Domestic) and Guarulhos (International) Airports (22 and 46 million passengers, respectively, in 2019). Congonhas is surrounded by urban development. The hypothesis of this study was to verify if a similar process is happening around Guarulhos. This study investigates population density on runway alignments and the trend of real estate development from 1985 to 2013 by using “heat maps” superposed to an “Alignment Radial Model” (ARM) comprising a central circle from 0-2 km and concentrically radial rings at 2-4 km, 4-6 km, 6-8 km and 8-10 km radius. The 2010 population was computed in Census sectors within the ARM. Real estate development data of both runway-aligned and -dis-aligned was mapped in several years’ periods over the ARM. Results show intense real estate development Northwest of Congonhas from 1985 to 2004, with a similar pattern the Western alignment of Guarulhos airport’ runways since 2005. High population densities are noted in 2010 South of Congonhas and East of Guarulhos airports, where little or no real estate development occurred along 1985-2013, indicating informal dwellings. Evidence shows that the urban development conflicting with Congonhas airport is being replicated around Guarulhos airport, rendering both unable to expand their runways, restricting São Paulo’s airports system capacity. This brings further challenges both for airport and urban planners to increasing airport capacity at São Paulo.","PeriodicalId":30302,"journal":{"name":"Transportes","volume":"17 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A ocorrência de sinistros envolvendo o micromodo – ainda que proporcionalmente pequena em relação ao número de viagens realizadas, conduziu um esforço de diferentes atores em compreender como o espaço urbano deve ser otimizado de forma a maximizar oportunidades e minimizar riscos. O presente trabalho avalia a importância de características do ambiente construído na escolha de se utilizar o PE, segundo a percepção daqueles que conhecem Belo Horizonte. Partindo-se de indicadores de ciclabilidade, aplicou-se Questionário Online baseado em Escala Likert. Os resultados indicam que o perfil predominante do usuário de PE – homem, adulto jovem, alta renda e escolaridade, corresponde àquele observado na literatura. 82% consideram utilizar o modo, mas 61% apontam que a cidade não apresenta as condições necessárias para sua operação. Pelo Método do Intervalos Sucessivos (MIS), verifica-se que os fatores mais importantes são a conservação do pavimento e a presença de rota cicloviária.","PeriodicalId":30302,"journal":{"name":"Transportes","volume":"23 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138979206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Devido à escassez de dados de exposição de pedestres, a modelagem da segurança viária pode utilizar variáveis proxy advindas do ambiente construído para representar a exposição quantitativa dos pedestres e o planejamento urbano nem sempre considera o pedestre ou estima junto a outros modos ativos. Em busca de priorizar os pedestres devido a sua maior vulnerabilidade comparado a outros modos, o objetivo do artigo é estimar a densidade de viagens a pé em zonas de tráfego a partir das características do ambiente construído. O método propõe a comparação entre os seguintes modelos: regressão linear clássica (global), regressão geograficamente ponderada (RGP) e a recente abordagem de regressão geograficamente ponderada de múltiplas escalas (RGPME). A análise dos resíduos comprovou que a especificação do modelo de RGPME é mais eficiente quanto o ajuste do modelo e na redução da autocorrelação espacial. A densidade populacional, a extensão de vias por área da zona e a distância ao transporte público estão entre as variáveis preditoras significativas para a estimação do número de viagens a pé por área da zona de tráfego.","PeriodicalId":30302,"journal":{"name":"Transportes","volume":"17 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138980144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the performance of maintenance carried out on unpaved roads in technical, economic, and socio-environmental scopes by application of the Highway Development & Management Model (HDM-4) and to show the best project proposals. The analyses consisted of inputting the HDM-4 with the characteristic data of roads, of and the maintenance to be adopted and the type of used vehicle. The association of this information made it possible to envision scenarios that consider either the replacement or non-replacement of gravel materials on the roads as a methodology. For management without gravel replacement, the most effective scenario was that of roads with gravel under the bed, located in a tropical climate, with flat features and 90 kilometers in length, initial thickness of 175 mm of gravel, high volume of traffic, and subject high-level maintenance at 30-day intervals. For the management with gravel replacement, the ideal scenario was that of roads with gravel under the bed, located in a temperate climate, on rolling terrain and 30 kilometers long, initial thickness of 175 mm of gravel, high traffic intensity, and subjected to high-level maintenance every 30 days. High-level maintenance was the best option for maximizing the quality of the roads and providing the best total net benefit, lowest gas emission rates, least fuel, and tire consumption, and adequate pavement condition by the end of the project.","PeriodicalId":30302,"journal":{"name":"Transportes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48472134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite many solutions that address this problem, the lack of understanding of the spatial pattern of urban deliveries makes it challenging to implement these strategies. This paper analyzed the spatial relationship between sociodemographic, retail and e-commerce deliveries in Belo Horizonte (Brazil) by using official data at the neighborhood level (number of retail shops, gender, income, age, race, and household size), and e-commerce deliveries performed by a transportation company. Global Moran's I indicated the spatial dependence of the e-commerce deliveries. Results of a geographically weighted regression model showed a positive spatial effect of retail, women, Asian population, age from 20 to 29 years old, and income. In addition, a negative spatial effect was identified for the size of the household, 18 to 19 years old, and the black population. Furthermore, the estimated coefficients show small spatial variability, indicating homogeneity in the spatial relation. The uniformity of the parameters indicates that alternative strategies can be implemented throughout the territory to reduce e-commerce deliveries.","PeriodicalId":30302,"journal":{"name":"Transportes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49649644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
