Abstract: Fractal dimension analysis for a transport network structure is essential for urban road network planning. The present study attempts to evaluate road network in terms of fractal dimension using Geographical Information Systems (GIS) with a symbolic case study of Hyderabad city, Capital of Telangana state, India. The study implements mass-radius fractal method for quantifying fractal dimension of the road network by increasing the buffer radius. The present work also focuses on developing a model that explains the relationship between network structure and fractal aspect of the road network using Multiple Linear Regression (MLR) analysis. The similarity of the road network pattern at different locations of city is presented in this study. The results of the study showed that there is diversity in the growth and development of the road network in the city. This research tried to explain the relevance of fractal dimension analysis in transportation planning.

Keywords: fractal; evaluation; GIS; similarity; model.
