description Devising urban mobility plans for Brazilian cities, especially small ones, lacks technical support, such as altimetric surveys that allow the representation of the terrain accurately, causing many transportation planners to benefit from Digital Elevation Models (DEMs). This study aims to evaluate the usability of TOPODATA DEM to measure the accessibility of cyclists to their potential travel destinations. A case study was conducted in the city of Bariri-SP (Brazil), where altimetric data collected using GNSS technology was previously available. Expected speeds for cyclists were assigned to the road segments as a function of their respective TOPODATA and GNSS slopes, allowing the identification and comparison of the shortest homologous paths between the units of analysis and bicycle Trip Attractors (TAs). The homologous accessibilities in each unit of analysis were also compared with each other, and the differences between them were evaluated according to their spatial autocorrelation, in addition to their spatial dependence on TOPODATA altitudes and slopes. The impact on the overall accessibility of different population groups in the city when using the DEM was also observed. The results suggest the shortest homologous paths that are quite similar to each other, although the accessibility samples for both sources of altimetric information differ statistically. A strong spatial autocorrelation was observed between differences in homologous accessibilities, but moderate to weak spatial dependences were observed between this variable and TOPODATA altitudes or slopes. The overall accessibility of each evaluated population group is similar regardless of the criterion used.

Este trabalho tem o objetivo de avaliar a usabilidade do MDE TOPODATA para mensurar a acessibilidade de ciclistas a seus potenciais destinos de viagem. Um estudo de caso foi conduzido em Bariri-SP, onde dispunha-se previamente de dados altimétricos levantados com a tecnologia GNSS. Velocidades esperadas para os ciclistas foram atribuídas aos segmentos viários em função de suas respectivas declividades TOPODATA e GNSS, permitindo identificar e comparar os caminhos mínimos homólogos entre as unidades de análise e Polos Geradores de Viagem (PGVs) por bicicleta. As acessibilidades homólogas em cada unidade de análise também foram comparadas entre si, e as diferenças entre elas foram avaliadas de acordo com sua autocorrelação espacial, além de sua dependência espacial com relação às altitudes e declividades TOPODATA. O impacto à acessibilidade geral de diferentes grupos populacionais de Bariri-SP quando utilizado o MDE também foi verificado. Os resultados sugerem caminhos mínimos correlatos bastante semelhantes entre si, apesar das amostras de acessibilidades para ambas as fontes de informações altimétricas divergirem estatisticamente. Observou-se uma forte autocorrelação espacial entre as diferenças de acessibilidades homólogas, porém dependências espaciais de moderadas a fracas entre esta variável e as altitudes ou declividades TOPODATA. A acessibilidade geral de cada grupo populacional avaliado é similar inobstante ao critério utilizado.Universidade Federal de Uberlândia2022-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/6511710.14393/rbcv74n3-65117Brazilian Journal of Cartography; Vol. 74 No. 3 (2022): July/September; 691-709Revista Brasileira de Cartografia; v. 74 n. 3 (2022): Julho/Setembro; 691-7091808-09360560-4613reponame:Revista brasileira de cartografia - RBC (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/65117/34582https://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/65117/34585Copyright (c) 2022 Marcelo Monari, Paulo César Lima Segantine, Irineu da Silvahttps://creativecommons.org/licenses/by/3.0/info:eu-repo/semantics/openAccessMonari, MarceloSegantine, Paulo César LimaSilva, Irineu daMonari, MarceloSegantine, Paulo César LimaSilva, Irineu da2022-11-28T20:21:48Zoai:ojs.www.seer.ufu.br:article/65117Revistahttps://seer.ufu.br/index.php/revistabrasileiracartografia/indexPUBhttps://seer.ufu.br/index.php/revistabrasileiracartografia/oairevbrcartografia@gmail.com1808-09360560-4613opendoar:2022-11-28T20:21:48Revista brasileira de cartografia - RBC (Online) - Universidade Federal de Uberlândia (UFU)false
