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