Gravity Model Calibration and its use in Trip Distribution

Abstract

Urbanization is a dominant process in the growth of nation’s economy. Ahmedabad is a 7th largest
metropolitan city in India. AHMEDABAD city is the administrative centre of Gujarat, India. Located at latitude 23.03°
North and longitude 72.58° east. Ahmedabad city is the centre for social, educational, commercial, residential, cultural,
political and economic activities. Due to the continuing expansion of cities with the development of societies and
technology through the ages make the existing transportation systems are not sufficient to meet the increasing demands
due to the difficulty and the complexity of the daily movements of people and goods. Traffic congestion is major
problem for smooth flow of vehicles in city transportation network. With increasing in number of vehicles due to
increasing of population in the city it may increase traffic problems, number of accidents, pedestrian safety, more fuel
consumption, Air pollution etc. The scope of the study includes the literature review and Gravity model calibration used
in Trip Distribution. As the database is essential part in decision making. The study will become base line study. The area
to be covered in the study of above transportation problem should be West zone of AHMEDABAD and its surrounding
urban areas. The area is to be divided into 9 zones based on ward boundaries. In this study mainly household survey is
carried out. This paper consists only up to methodology. Household survey will be conducted in future
