Resumo

A influência do ambiente construído na exposição de pedestres é um elemento essencial para análise da segurança viária e do planejamento urbano. 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.
