##article.abstract##

Road accidents in the Transport Industry are a threat to public health and national development in many developing countries. They contribute to poverty by causing deaths, injuries, disabilities, grief, lose of productivity and material damages. The study was undertaken in Uasin Gishu and Bungoma counties, with specific focus on road network. The major objective was to determine the effects of Geometry and environmental features on road accidents. The methodology and procedure for data collection was based on both qualitative and quantitative approach. Interviews, focus group discussions, observations and review of secondary data, were used in data collection. Statistical analyses of data were done by simple regression, descriptive statistics employing the measures of central tendencies. The results show that the road accident rate per kilometer per annum is significantly related to the vehicle flow whereas the rate per hundredth vehicle kilometers was found to be significantly related to the following physical characteristics of the road geometry; junctions per kilometer, surface irregularity and road width. The road accident rates in Uasin Gishu and Bungoma Counties were found to be consistently greater for similar values of vehicle flow and geometric design
