I28-R145-8043_oai2025-11-17 Matos, Bárbara Lobo, Carlos 2021-12-21 Highways inserted in the urban space have commonly become obstacles to access and mobility, especially for travel by non-motorized modes. This phenomenon, known as the “barrier effect”, intensifies with demographic growth, expansion of the urban fabric, and increase in the fleet of motor vehicles, as has occurred in several Brazilian cities over the past decades. In this context, the objectives of the present work are to estimate the volume of pedestrian crossings between the margins of the Celso Mello Azevedo Ring Road, an important route used in urban displacements in Belo Horizonte (Brazil), as well as to propose the application of indicators to assess the potential risk for pedestrian crossing. For this purpose, the travel databases of the OD 2012 Survey (RMBH) and the digital vector mesh of the traffic volume of the highway were used, and the results were compared with the occurrence of traffic-accidents per stretch of the highway. The results showed sections 3 and 1 have the highest pedestrian traffic between the margins, however, the application of the indicators pointed to a higher risk of crossing in sections 2 (high risk) and 5 (medium risk) due to the high volume of traffic and low availability of walkways, respectively. Rodovias inseridas no espaço urbano têm comumente se tornado obstáculos ao acesso e a mobilidade, especialmente para os deslocamentos por modos não motorizados. Esse fenômeno, conhecido como “efeito barreira”, se intensifica com o crescimento demográfico, expansão do tecido urbano e acréscimo da frota de veículos automotores, como ocorreu em diversas cidades brasileiras ao longo das últimas décadas. Nesse contexto, são objetivos do presente trabalho estimar o volume dos atravessamentos de pedestres entre as margens do Anel Rodoviário Celso Mello Azevedo, importante via utilizada nos deslocamentos urbanos em Belo Horizonte (Brasil), bem como propor a aplicação de indicadores para avaliar o risco potencial para a travessia de pedestres. Para tanto, foram utilizadas as bases de dados de viagens da Pesquisa OD 2012 (RMBH) e a malha digital vetorial de volume de tráfego da rodovia, e os resultados foram comparados com a ocorrência de acidentes por trecho da rodovia. Os resultados apontaram que os trechos 3 e 1 possuem a maior movimentação de pedestres entre as margens, no entanto, a aplicação dos indicadores apontou maior risco de travessia nos trechos 2 (risco alto) e 5 (risco médio) devido ao elevado volume de tráfego e baixa disponibilidade de passarelas, respectivamente. application/pdf text/html https://revistascientificas.filo.uba.ar/index.php/rtt/article/view/8043 10.34096/rtt.i25.8043 spa Facultad de Filosofía y Letras, Universidad de Buenos Aires https://revistascientificas.filo.uba.ar/index.php/rtt/article/view/8043/9798 https://revistascientificas.filo.uba.ar/index.php/rtt/article/view/8043/9823 Revista Transporte y Territorio; No. 25 (2021): Julio-Diciembre Revista Transporte y Territorio; Núm. 25 (2021): Julio-Diciembre 1852-7175 urban roads barrier effect community severance pedestrian crossing active mobility rodovias urbanas efeito barreira segregação socioespacial atravessamento de pedestre mobilidade ativa Barrier effect and pedestrian crossing on the Celso Mello Azevedo Ring Road, Belo Horizonte (Brazil) Efeito barreira e o atravessamento de pedestres no Anel Rodoviário Celso Mello Azevedo, Belo Horizonte (Brasil) info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=transter&d=8043_oai |
