Abstract
Current and past access management and traffic safety literature frequently states that decreasing the number of conflict points by implementing access management techniques leads to safer roads. However, after a review of literature related to access management and accident reduction factors, no clear relationship has been defined between the reduction of conflict points on a length of roadway and the expected reduction in accident rates. Although the value of good access management is somewhat intuitive, a better understanding of the relationship between conflict points and safety will provide an additional tool for predicting the safety benefits of various access management techniques. This research used before and after accident data from case study locations to investigate the relationship between a change in conflict points along a length of roadway and the expected reduction in accident rates. Although there is not a simple relationship between reducing conflict points and reducing accident rates, a methodology was developed for using weighted conflict points to predict the reduction in accident rates.
