College, Vinayaka Missions University, 2 PG Student of Environmental Engineering, Department of Civil Engineering, VMKV Engg. College,Vinayaka Missions University, Salem, IndiaAbstract: Design of ring road deals with the roads and bike roads routing determination (Mackenzie anddevelopment of a comprehensive plan for Construction and Walker 2004, Malpica ve Pedraza 2001). GIS based routeoperation of transportation facilities. In order to develop determination for railway (Ashish and Dhingra 2005, Kovefficient and better transport facility, it is necessary to have vd. 2005, Gipps vd. 2001), irrigation/drainage channelsa proper procedure transport movement. This ring road (Yusof and Baban 2000, Smith 2006), power line (Chenghelps to a great extent in improving the safe and fast and Chang 2001) have already been implemented.movement of both human and goods traffic, thereby The present study was initiated to demonstrate the use ofincreasing the economy of the City.This improved various data from different sources, GIS analysis and rastereconomy contributes the growth of the country. The first network analysis techniques for developing a least costand foremost step is reducing the traffic for the particular pathway for linear civil engineering structures. This isroute by diverting the density of the vehicles to enhance probably the most asked question posed to those in thethe safe transport and environmental pollution. This project Geographic Information Systems (GIS) field and isdeals with the traffic problem of the erode city and probably the hardest to answer in a succinct and clearprovides better transportation.In this project GIS is used manner.for surveying, for preparing Contour maps, for developingthree dimensional Digital Elevation Models, for various 1.2 SOFTWARE Different software packages are important for GIS.types of route alignments and for estimation of cutting and Central to this is the GIS application package.

The GIS myriad of GIS functions inherent to them. Extensions orapproach using ground parameters and spatial analysis add-ons are software that extends the capabilities of the GISprovided to achieve this goal.

Component GIS seeks to buildinformation surrounding linear infrastructure. Costs software applications that meet a specific purpose and thusresulting from terrain, geomorphology, land use, drainage are limited in their spatial analysis capabilities.

There are two primary I. INTRODUCTION types of data that are used in GIS. A geodatabase is a Determining the best route through an area is one database that is in some way referenced to locations on theof the oldest spatial problems. This problem has recently earth. Geodatabases are grouped into two different types:been solved effectively using GIS and Remote Sensing vector and raster. Vector data is spatial data represented astechnologies. During the last decade, a few attempts have points, lines and polygons. Raster data is cell-based databeen made to automate the route-planning process using such as aerial imagery and digital elevation models.GIS technology. A review of a number of papers suggests Coupled with this data is usually data known as attributethat the methodology is still at an exploratory stage (Saha et data. Attribute data generally defined as additionalal., 2005). Anumber of research have already been information about each spatial feature housed in tabularperformed in pipeline route design using GIS which include format.
