RESUMO

This doctoral research proposes a systemic methodology of street vehicular congestion analysis, pictured by some traffic jammed areas and its problems of land use accessibility and urban car mobility in Fortaleza city, capital of Ceará State, Brazil. The approach offers a composed computational modeling in Geographic Information System environment by joining both Urban Transportation Modeling Systems (UTMS) trip assignment using Stochastic User Equilibrium (SUE) and Space Syntax Angular Segment Analysis (SS-ASA). The main objective is to contribute to jammed areas main identification actors in Fortaleza city which would be explained by grid discontinuity links due to citys urban plans evolution. Besides that, it reveals the contribution of land use main attractors which would emphasize a congested Critical Area (CA). The research is a kind of interface between transportation and urbanism methodological and theoretical approaches and suggests analytic categories related to two scales. The first one, related to functional grid local and global accessibility and the second one, related to an arterial streets sample and their sociological consequences to the assessment to streets commercial and non-commercial land uses. The final results present the contribution of space to vehicular movement (the grid form), as a part of Fortaleza city urban evolution and vehicular congestion. The research defined three levels of accessibility analysis: macro, meso and microscope, together with two aspects of functional approaches. The results also confirm the sociospatial segregation the city has gone through and suggest new urban systemic approaches concerned to urbanism and transportation academics.
