Thinking Analytically: A long walk

John ToczekBy John Toczek

Walking in large cities poses some risk to pedestrians. There are poorly designed intersections, mistimed lights and commuters in cars that are anxious to get to their destination.

My new commute to work includes a one-mile walk, which is represented in the accompanying map. Each line represents a segment of that walk, and the line color represents the level of risk for that segment. Red indicates a high-risk section, orange indicates a medium risk section, and green represents a low risk section.

Analytics Puzzle

Danger ahead: A one-mile walking commute.

Move from circle to circle in any direction you like from start to finish while trying to minimize the total risk. To calculate the total risk of the walk, add up points for all segments as follows: green = 0 points, orange = 1 point, red = 2 points.

Question:

What are the minimum total risk points that can be achieved for the walk?
