A.P. India. Abstract— In urban area the road user is facing important issue is traffic blockage. This convinces is moving out cost-effective of travel, contamination, touching strains of traffic mobility. It is important to indentify factors for the exclusive convince cause to be in traffic. The factors are capable to be tracked with the attribute positioned on road with speed. The blockage is caused with the speed is distributed with unpredictable intensities show the way to blockage. These quantity is initiated that they are due to control of convinced attribute sway from factors of land use, road geometric, and traffic and road network uniqueness. This paper is framed on with the number of influencing factors. The input data is collected from field survey, GPS Technology, GIS based caring data and data from local concerned authorities. Keywords— Blockage, lessening, urban, geometric, degenerate, network. I. INTRODUCTION Urbanization is intimately associated to development in industries, socioeconomics and improvement in living standards of the people. Hasty Urbanization origin of disordered furthermore unintended expansion of urban cores which turn into additional complicated through the reality that it have to acquire inside the built up area. Urbanization working in the border carries a number of transport troubles of protection, blockage, disasters, parking, administration and enforcement. The paper is effort with reference to the geometric, traffic, utility and land use characteristics of the study region, to classify the most important corridor through traffic individuality as self-governing uniqueness of blockage standard as origin to classify the links leading to blockage. Principal component analysis The fundamental design of principal component analysis (PCA) is to lessen the dimensionality of a statistics set consisting of a hefty quantity of organized variables, while retaining as a great deal as feasible of the discrepancy present in the statistics set. This is attained by transforming to a innovative set of variables, the principal components (PCs), which are uncorrelated, and which are structured so that the original few preserve the largest part of the difference present in all of the innovative variables. The flowchart showing the step by step procedure of conducting Principal component analysis is presented in Fig .1 Fig.1: Principal component analysis graphic representation II. STUDY AREA To study Rajendranagar municipality Telangana state is considered. The place of the study area is shown in Fig2.The land use activities are predominantly of mixed type constituting residential, commercial and industrial. The traffic is mixed traffic conditions. There is no defined functionality of the road systems in the Municipality. Input data for attributes are collected satellite data by using GPS, GIS as compassionate tool and field surveys, collected concerned municipal authorities.
