    ASSESSMENT OF MINIBUS TAXI TRANSPORT SERVICE CHALLENGES AND PASSENGER FARE ESTABLISHEMENT A CASE STUDY ON FOUR SELECTED ROUTES OF HAWASSA CITY, ETHIOPIA
    (Hawassa University, 2021-04-11) GETU BEKELE FEREJA
    In the developing cities like Hawassa an increase in size and number of population generate increased travel demand and triggered improved transport service. Among the public transport modes, the service provided by minibus taxi are unattractive due to the presence of a factors like providing service quality problem, mismatching of demand and supply of mini bus taxi and the transport fare system problem. This study aimed to evaluate the existing service quality, the distribution pattern and passenger fare establishment methods of mini bus taxis in the city and compared the current using taxi distribution and passenger fare with four stage demand modeling results and HDM-4 software based results respectively. Regarding with this, the data’s like characteristics of vehicle, geometric characteristics of road, price of vehicle component, and various traffic data were collected through field survey, interview and questioner survey methods. The qualitative analysis which is subjective measures were used. For analysis of taxi distribution four stage demand modeling and other statistical analysis model which were fit to our data such as category analysis, gravity model and logit model were used and to establish the passenger fare HDM-4 multipurpose software were utilized. The finding of this study result revealed that more than half of transport users are dissatisfied on over all service provision of minibus taxi. Related to the result of taxi distribution The number of trip attraction and production for route of old bus station to mobil station of each purpose of trip home to work, home to school, home to shop and home to other purpose found to be 2657,3024,1602and1947respectively and for production trip purposes the number of trips were found to be 2018,1982,1919 and1784 respectively.. Concerning with result of passenger fare produced by HDM-4 software, the fare produced for one km road segment was about 1.35 Birr person; however the fare established by Hawassa city transport office was 0.75 cents per person. Finally, proper consideration of input parameters is required when setting passenger fare for each mode of transport and the transport bureau should studied further on demand and supply of mini bus taxi and service delivery in order to improve the operational system of minibus taxi in the city

    ASSESSMENT OF PROJECT PERFORMANCE: CASE OF 40/60 SAVING HOUSE DEVELOPMENT ENTERPRISE IN ADDIS ABABA BOLE AYAT LOT II
    (Hawassa University, 2018-10-22) ALIYA ABDOSH IBRAHIM
    Construction industry has complexity in its nature because it contains large number of parties as clients, contractors, consultants and other stakeholders. Construction projects suffer from many problems and complex issues in performance such as cost, time and quality. The aim of this thesis is to identify and evaluate the main factors affecting the performance of construction projects in the case of Bole Ayat 40/60 condominium. Literature reviews about performance were sited to identify the factors affecting the performance of construction projects. The methodology/research design followed was descriptive research. A questionnaire survey was conducted and 44 factors were identified, categorized, evaluated and ranked from small and micro enterprises, client, consultants and contractors perspectives. The results were analyzed and discussed to obtain the most performance indicators. The relative importance index (RII) method was used here to determine perceptions of the relative importance of the performance indicators in construction projects. The extremely significant factors affecting time performance were shortage of material, financial problem and poor communication and coordination with RII 0.75, 0.74 and 0.71 respectively. Whereas the factors affecting cost performance were fluctuation in the cost of material, lack of cost planning and design change with RII 0.77, 0.693 and 0.691 respectively and factors affecting quality performance were educated and experienced personnel, quality of materials and equipment used in the project with RII 0.81, 0.72 and 0.69 respectively. Recommendations were formulated to improve performance of construction projects. It was concluded that every party participating on the project should have good communication and coordination to avoid design discrepancies and disputes to improve performance; they should have to hire qualified personnel to overcome any technical and managerial problems
