| 摘要： | Increasing road accident rate is a matter of serious concern. With the limited funding allocations, it is imperative to prioritize the accident prone locations to identify the location with high potential for accident reduction after improvement. Road accident occurrence is random in nature and variation in number of accidents over a period of time should not be counted as the result of improvement measure (often called as regression to mean effect). Empirical Bayes approach is one of the universally accepted safety evaluation method for performing before and after analysis of treatments. The prerequisite for Empirical Bayes analysis is Accident Prediction Models also called as Safety Performance Functions. Accident Prediction Models not only help in predicting the number of accidents and evaluating alternate measures but also help in evaluating the effectiveness of a treatment. It is proven that Accident Prediction Models are the key for evaluation of improvement measures using before and after analysis. Realising the importance of the Accident Prediction Models, many countries have developed them and included them as a part in their economic evaluation manuals. Hence 106 intersections in Chennai were chosen and their volume count data were obtained from the previous studies for the development of Accident Prediction Models. |
