The following diagram illustrates the number of conflicting points at a 4-approach unsignalized intersection with one lane for each approach. The conflicting points are classified as points for merging, diverging, and crossing. How many conflict points will there be if the intersection geometry is changed to two off-set “T” intersections? Scratch your solution and label all conflicting points by classification.
