Statistical Analysis of iRAP Star Rating on Thai Rural Road Network
Abstract
Road Safety Problem is a huge competitive disadvantage of our country. While the major cause of most accident is human factor, road safety condition is another important risk factor that contribute to the frequency and severity of accident. Hence, it cannnot be neglected. Department of Rural Road has implemented the methodology of International Road Assessment Programme to evaluate the safety condition of road in responsibility. However, parameter used in iRAP methodology are based on foreign study especially accident modification factor which is the critical part of the model. The transferabilty of these parameter is questionable. This study is about the statistical analysis of iRAP star-rating against crashes data. The result of this study suggest the application of current iRAP model and developing framework for more localize model in the future
