Single Camera Traffic intersection

Same may classify intersections as 3-way, 4-way, 5-way, 6-way, etc. depending on the number of road segments (arms) that come together at the intersection.

3-way intersection – A junction between three road segments (arms) is a T junction (two arms form one road) or a Y-junction.
4-way intersections are the most common, because they usually involve a crossing over of two streets or roads. In areas where there are blocks and in some other cases, the crossing streets or roads are perpendicular to each other. However, two roads may cross at a different angle. In a few cases, the junction of two road segments may be offset from each when reaching an intersection, even though both ends may be considered the same street.
5-way intersections are less common but still exist, especially in urban areas with non-rectangular blocks.
6-way intersections usually involve a crossing of three streets at one junction; for example, a crossing of two perpendicular streets and a diagonal street is a rather common type of 6-way intersection.
Seven or more such segments coming together at a single intersection are rare.
