• W2908052376 abstract "Propose a pedestrian crosswalk safety rating (PCSR) for primary roads in Mexico City in order to rate crosswalk safety at intersections with a traffic light and then compare the PCSR with traffic accidents so as to empirically determine any association between the quality of the crosswalk and the traffic accident rate.Identify criteria for the rating system through a state-of-the art review; weight the criteria to create a rating system through multicriterion analysis; design a stratified random sample of crosswalks (n = 490); and evaluate the data set.Through the PCSR, 91.3% of the crosswalks evaluated in Mexico City were found not to offer the conditions required to protect pedestrian safety; the access macro-criterion received the worst scores. The modelling shows that mixed land use and the length of the crosswalk are the most important variables in predicting traffic accidents.The analysis was relatively successful in showing the relationship between some variables (criteria) of the PCSR and traffic accidents. In many cases, this shows theoretical coherence; in others, research questions are raised.Propor um índice de segurança de travessia de pedestres (ISTP) para as principais vias públicas na Cidade do México para classificar as travessias de pedestres semaforizadas e comparar o ISTP com os dados de trânsito para comprovar empiricamente se existe associação entre a qualidade dos locais de travessia e a taxa de acidentes.Foram identificados os critérios do índice com uma revisão do conhecimento atual e os critérios para gerar o ISTP foram ponderados com uso do método de análise de decisão multicritério e delineamento e avaliação de uma amostra aleatória estratificada de travessias de pedestres (n = 490).Com respeito à avaliação das travessias com o uso do ISTP, verificou-se que 91,3% das travessias avaliadas na Cidade do México não têm condições ideais para resguardar a segurança dos pedestres, com o macrocritério “acessibilidade” com a pior qualificação. Quanto à modelagem, observou-se que a mescla de usos do solo e a distância da travessia são as variáveis explicativas mais importantes para predizer a ocorrência de acidentes de trânsito.A análise demonstrou com relativo sucesso a relação entre algumas variáveis (critérios) que compõem o ISTP e acidentes de trânsito. Houve uma coerência teórica em muitos casos, porém em outros suscitou dúvidas a serem investigadas." @default.
