Abstract
Addis Ababa keeps expanding horizontally as a result of increase in wealth and population, the
city has faced some problems like congestion, poor access to work place, education, health and
other services due to lack of properly planned urban transport and lack of improved transport
modes, mobility in the city which has becomes a big issue. This study is designed to assess urban
transport mobility with trip distribution methods to calculate expected number of trips between
origin and destination zones, to identify factors that affect personal trip production with respect
to travel pattern and finally to forward recommendations based on the analysis made to improve
the urban transport planning system. In order to solve the stated problems and meet the
objectives both primary and secondary data were collected. In relation to secondary data, related
documents were reviewed. Regarding primary data, expected numbers of trips between two
zones were estimated using gravity model. The total number of estimated trips was 360,672
trips/day and the actual trips that were counted were 3,450 trips/day. To balance these two trips,
calibration constant was calculated. Questionnaires were distributed to different population
groups randomly and were analyzed using SPSS software. Semi structured interviews were used
to collect data related to transport planning system. As a result study identify parameters that
can affect urban mobility with regard to trip person production based on the travel behavior and
socio economic activities like income, household size, educational back ground, number of
employees, travel time, number of trips, trip purposes and transport expenses. Incomes people
earned had significant influence on the type of transportation they frequently used, which is also
an implication of their daily expense for transport. Urban transport challenges regarding
population growth, inadequate urban transport planning and fast growth in urbanization resulted
in congestion, poor mobility and accidents. Lastly, the study recommends that there has to be a
policy that coordinates urban and transport planning policies to make an integrated transport land
use systems which reduce the distance travelled, time taken and use of personal vehicles along
with increasing accessibility through proper land allocation for different activities and
government must plan new policy to decrease migration from rural areas to the city for different
purpose by providing sufficient services at home town. Additionally, the study recommends the
use of high capacity vehicles can improve urban mobility and traffic rules enforcement must
have conducted to reduce traffic accidents.
