Walking is one of the most important travel modes in the world so pedestrian facilities need tornconcern while transportation planning, construction, and management. However in ourrncountry road design manual for urban sections outside Addis Ababa are classified on dependrnon the governmental administrative system (Kebele, Wereda, Zone, and Region). EthiopianrnRoad Authority geometric manual provide road Cross-sectional elements depend on thernadministrative classification system. Forecasted Population, roadside settlement, and growthrnof pedestrian numbers are not concerned. Not giving attention to the pedestrian facilities arisesrnwith questions after the road has been constructed, also the performances of the sidewalks arerncome to be inadequate and poor. Also Despite with insufficient sidewalks comes with the poorrnperformance of the walkway. The performance of the sidewalk is measured by the pedestrianrnlevel of service (PLOS). PLOS is Assessing, describing existing conditions, and evaluating thernoverall Quality pedestrian facilities.rnIn this research, it needs to address model representing the PLOS with various factors whichrninfluence the level of service for roadside walkway including pedestrian perceptions. Thernstudy is conducted in Ethiopian, for the Case of Oromia Special Zones surrounding AddisrnAbaba from Ashewa meda to Holeta. Data collection was done by questioners and siternsurveying. The selected factors which influence PLOS for the study area are Safety, Comfort,rnWidth of a sidewalk, surface condition of the sidewalk, and Zebra crossing. 876 Questionersrnwere distributed and collecting pedestrian perception on the factors of PLOS. Participants arernrepresented a cross Section of age, gender, and walking experience. Also, field surveying wasrnconducted to collects road cross sectional elements and overall condition of the site.rnOrdered logit model was used to develop a model by Identification and relate to factorsrnaffecting PLOS. On correlations of the variables, all Predictors are strongly correlated andrnstatistically significant. With Pseudo-R2=78%. The model contained all eight predictors andrnwith no variables removed, PLOS was predicted by Zebra crossing, Width, Surface, ComfortrnSafety, length of walking, frequency and time of walking.rnBy using the developed model the PLOS is ranging A to F, finally with the last model thernstudy areas' pedestrian level of service is evaluated.
