There are several proximal safety indicators that help determine the safety of uncontrolled intersections without using past accident data. This study is based on post encroachment time (PET) as safety indicator. This analysis aims to find out the percentage of critical conflicts by combining post encroachment time with the conflicting speed of vehicles. Research has been done firstly by considering all the right-turning vehicles together and then all classes of right-turning vehicles separately. Among multiple crossing scenarios, the maximum proportions of conflicts occur between right-turning two-wheeler (2w) and through moving 2w and right-turning 4w and through vehicle 2w, and found a relationship between traffic volume and PET, after seeing the correlation between them, which is found to be negatively correlated and there developed a model, and R square values are compared for the best fit model.
