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.
