GONZALEZ, CARLOS  y  SARMIENTO, IVÁN. TRIP DISTRIBUTION MODELING AT ABURRA VALLEY USING THE GRAVITY MODEL. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.158, pp.199-208. ISSN 0012-7353.

This paper is based on recent studies of transportation which took place in the Metropolitan Area of the Aburra Valley: Survey Origin/Destination 2005 and Study of bus routes, the Road Network Modeling of the Aburra Valley, and Mobility Master Plan. The analysis and development of trip distribution model in the Metropolitan Area of Aburra Valley is done by using the software TransCAD for the database of 2005, using the gravitational model which determines the trips between two zones in accordance with the generation and attraction of trips between related zones and a impedance function that depends on the distance between zones, travel time or travel cost between zones. The model was analyzed for different periods and purposes and it was found that the negative exponential is the impedance function which adapts best to the studied model.
