Abstract
Various local is international organizations are located in Addis Ababa
and hence high level of mobility is existing in the city that demands
various forms of transportations. Automobile is the most common form of
transportation mechanism in the city. However there is high traffic
congestion with greater impact on the day to day activity of the
metropolis. This study considers the suitability of cycling as additional
means of transportation. In order to do this around 9048 streets in Addis
Ababa are evaluated to find out the best road for cycling. Factors such
as slope, traffic density and pavement surface condition were considered
to assess the suitability of roads for bicycle. The study was conducted in
two steps. The first step involved evaluation of the entire roads of the city.
When considering all factors, the result indicated that riders can use
bicycle only on 9% of the roads. The data analysis showed that the factor
‘pavement surface’ condition was the most infantile to limit the suitability
of roads for cycling. Using this factor alone about 65% of the total roads is
found to be unsuitable.
As an attempt for detail study the second step considered only five roads
among the total 9048 streets. The roads are selected from Arada sub-city
where there exists high traffic density and people with different socio
economic background. The detail analysis again considered the same
three factors and the result indicated that the route running to Gullele
found to be the best as its slope, traffic condition and pavement surface
condition is suitable for cycling. In contrast the road that runs to Art Kilo is
the worst because of the traffic density and pavement surface condition.
