Methodology for estimating freight flows from secondary data: an application in Belo Horizonte

Metodologia para estimativa de fluxos de carga a partir de dados secundários: uma aplicação em Belo Horizonte

Good planning of freight flows in the urban environment requires knowledge of the freight Origin Destination (OD) matrix. This study aims to propose a methodology to estimate freight flow from secondary data, employing the principles of activity-based models and evaluate its general applicability. The methods traditionally used for obtaining OD matrix have a high cost and methodological difficulties in data collection, making impracticable its updating. The proposed methodology is based on the location, type of activity and the explain variable of the generation model and it consists of seven stages, including the definition of the study area, zoning, choice of economic segments, collection and treatment of secondary data, trip generation, distribution modeling and calibration. The methodology was applied in Belo Horizonte (MG), based on data from the Municipal Register Contributors from 2011. The model was built based on the principles of Integrated Land Use and Transport, applying the model TRANUS. For calibration, it was used official data from the municipality and previous research. The methodology proved being applicable, and it provided an estimated OD matrix compatible with the reference data.
