ABSTRACT
The Trip Distribution is the most complex and also important model in the urban transportation planning process .This paper gives a framework to calibrate a doubly constrained gravity model of the trip distribution stage for the AVKUDA area based on a Household Information Survey which is carried out in 2014-2015. Large sample is used for the calibration of gravity model. The model is also validated by comparing observed and calculated trips by calibrated gravity model. Calibration is carried out for different trip purposes like home based work, home based education and home based shopping trips using Trans CAD software.
