dc.description.abstract	ecause of the need of route selection. Linear P.ngineering Structures (LES) require strategic ph':'1ing. evaluation and management. The operations ro choose optimum route depends on the effective collection, processing, storing and analysis of spatial data such as topography. vegetation, geology, soil type. land use. and landslide areas about land. This situation requires using of Geographical l11forn1ntlon Systems (GIS) by providing effective data munagcmcm. This thesis tries to lntroducc a coherent GIS and RS based spatial analysis for the generation of opumat routings for I.ES and Sflj(dfically for best highway alignment selection into the current transportation system in Ethiopia. To obtain an optimum highway mule alignment which is economical, suitable anti compatible with tl1~. environment, various types uf data have to be considered simultaneously. So that in this research . . work l:m<l11se, geology, existing road network, slope, DEM and soil criteria arc considered. In evaluating all the criteria it is a must that the parameters need to be keep i11 their priority order. This was performed in tile thesis using IDRIS! software that weighs the parameter; with the help of AHP • Abstract which uses pair wise comparison (PWC). • :IJ Then weighted overlay analysis were. performed according 10 relative percent influence of the parameters after changing all the parameters into raster formal. Because of the complexity of the problems a number of tools like ArcGfS 9.2, ERDAS Imagine 8.7. AutoCi\D2007 and other ancillary softwares have been deployed to arrive at the proper solution. Finally, shortest path spatial analysis was used and a new Highway route or path connecting Akaki -Kality and Dole sub cities was obtained. The starting point and the destination point were being determined using handhold GPS. The thesis ll<b sw.:w:xlt.xl in showing th<~ it is possible Lo On the basis of the findings of the. new highway route .of the study plays a key role in minimizmg traffic congestion, accident rate in urban areas and for the economic growth of the country, ii is also recommended thu1 the 11.,e GIS amt RS is more advantageous in terms of time, cost and be environmentally friendly in analyzing multi-criteria for Highway Engineers and Planners in selecting an optimum route of I .inear F.ngineering Structures (LES}.
