The Study area of NH-67 covering a length of 80kms from Nagapattanam to Tanjavur is chosen as a studyarea. The road layout plan has been exported from CAD to Arc GIS for digitizing. In this study area, the factors reducingthe speed of the vehicles are collected by using Tools like Arc GIS, Google earth & Auto CAD. From the data collected,the factors which are incorrect those are responsible for decreasing the speed is sorted out by comparing the values withIRC Specifications. The sorted out values are converted into co-ordinates(x, y). Then all the factors are divided into threecombinations with standard values and present values. The speed reduction rate is estimated by triangle modelmethodology in these following steps like Representing in Triangles , Finding the distance between the centroids,deriving Quadratic Polynomial Equation, Differentiating the derived equation with respect to distance as the limit. Afterdifferentiate we get a value and it is taken as speed reduction rate. The process is repeated for remaining combinations.
