main objective of the study was to identify the causes and consequencesrnas well as the temporal and spatial variations of taxi traffic accidents in Addis Ababa.rnThe research was based on primary and secondary sources. Three types ofrnquestionnaires were distributed to taxi drivers, non-taxi drivers and pedestrians. ThernGlobal Positioning System (GPS) instrument was used to locate the major taxirnstations and accident-prone areas on maps. Different maps were made using thernGIS Arc view. The archives of The Addis Ababa Traffic Police Traffic AccidentrnControl and Inspection Department and the Addis Ababa City AdministrationrnTransport and Communication Bureau were used as sources of information.rnThe study considered a number of factors grouped into driver, vehicle,rnpedestrian, and environmental factors. Also problems associated with the numberrnand facilities of the traffic police department as well as the traffic regulation itself werernassessed. The study indicated that the concentration of economic activities andrnservices, negligence of taxi drivers and working for longer hours, older taxi vehiclernfleet, and inadequacy of traffic control facilities are among the main causes of taxirntraffic accidents. Also the low level knowledge of pedestrians about the traffic rules,rnthe small number of traffic police working for long hours without incentives,rninadequate facilities and the lack of enforcing capacity of the traffic regulation itselfrnhave also been identified as the main contributing factors to the incidence andrnmagnitude of traffic accident in Addis Ababa.rnThe spatial variation of taxi traffic accidents showed that accidents are highlyrnconcentrated along the busiest roads, squares and around schools, governmentrnoffices worship areas, commercial, recreational as well as dense residential areas.rnThe study also indicated that taxi traffic accidents coincide with peak hours of the dayrnand weekends.rnOn the basis of the findings of the study, it has been recommended that thernexpansion and improvement of road facility programmes should be supported withrnprompt remedial measures such as the decentralization of functions, traffic educationrnfor children, strict driver training and licensing and public education for pedestrians.rnAlso it recommends the proper management of the available road facilities, andrnrevising of the existing traffic regulation to enhance its enforcing capacity on thernoffenders
