- •
Empirical Bayes (EB) before-and-after method was used to evaluate the safety performance of Intersection safety devices (ISDs) at an intersection level and approach level.
- •
Significant reductions were found for total collisions, rear-end collisions and angle collisions.
- •
Site selection criteria were evaluated and speed limits, presence of separated right turn lanes and the number of lanes were found to impact ISD collision reductions.
