ABSTRACT
The relationship between geometric design elements and accident rates is complex and not
fully understood. Relatively little information is available on relationships between
geometric design elements and accident rates. Intersections are usually considered as the
critical points within the urban road network and the evaluation of their performance
provides valuable understanding and useful indication about the performance of the city
road network system. The existing roads design does not provide adequate facilities for
pedestrians and hence, there exists a constant conflict between the pedestrians and the
vehicles in sharing the limited space available on a road. At intersections, pedestrian
crossing behavior is even more complex since the vehicles have very little response time
to control the vehicles, particularly in urban areas. All these issues are pointing towards the
research work required for studying the road crossing behavior of vehicles and pedestrians
at urban intersections. Pedestrian is one of the important component in urban transportation
system and also vulnerable at locations under mixed traffic conditions. At intersection,
some of the vehicles may yield to pedestrians who are already at crosswalk location.
However, some of the pedestrians are using forced gaps to cross the road. Hence, while
pedestrians use the un-signalized intersection crosswalk with forced gaps, which decreases
the vehicular flow characteristics. The pedestrian sidewalks do not show a direct effect on
the vehicular flow characteristics when the pedestrian have pleasant walking facilities. The
present study has analyzed the effect of pedestrian crossing on the characteristics of
vehicular flow at un-signalized intersection under mixed traffic conditions.
The result of this study indicates that the studied intersections Agep, Fikre café, Left side
of St. marry church, Bank of Commercial and Agricultural College in the Sodo city
currently serving in poor condition of facility. Thus, after carrying out additional detail
investigation and taking into consideration future traffic growth appropriate improvement
