There is a high rate of road traffic accidents happening on highways, especially those involving motorcycles. Motorcycle accidents are a major crash occurrence in traffic flow, especially in mixed traffic. However, there are insufficient studies, using a model based on geometric and traffic flow in highlands region, conducted on motorcycle accidents. This study focuses on motorcycle accidents happening in the highlands region of Batu City, East Java Province, Indonesia as a case study, to solve the problem of high rate of accidents involving motorcycles, by employing the Generalized Linear Model. Based on the accidents data, the number of traffic accidents in the city of Batu is considered to be high. By using accidents data, observation on traffic and road geometry, the model was developed. Using some statistical analysis, it is found that motorcycle accidents model that is influenced by traffic flow, shoulder width and speed, are the best-fit. Therefore the local government should improve some related factors (flow, shoulder width and speed) in order to reduce the number of motorcycle accidents in the city of Batu. © IAEME Publication.
