## Solution:

Explanation:

For the intersection of two-lane two-way roads from both sides:

Major conflicting points = 16, Minor conflicting points = 8 and thus total conflicting points = 24

For the intersection of two-lane one-way rod and two-lane one-way road:

Major conflicting points = 4 Minor conflicting points = 2 and thus total conflicting points = 6

For the intersection of a two-lane one-way rod from both sides:

Major conflicting points = 7 Minor conflicting points = 4 and thus total conflicting points = 11

Important Points:
