Accident Prediction Models at Signalised Intersections: Right Turn Against Accidents

Previous research on right turn against accidents at 4-arm, two-way traffic signals has identified that the daily volume of right turning and through traffic are key predictor variables for accident occurrence. The objective of this research was to consider a number of non-flow variables, and determine whether these are also key predictors for accident occurrence. The outcome is a more refined accident prediction model for this accident type. A particular interest was the impact of right turn phasing on accident occurrence.
