1 point for each kilometer
25% bonus for an AT trip.
25% bonus for age 1 - 16 or 65 +
25% bonus for wearing a helmet.
For example, if a 67 year old person rode 10K to work instead of taking a car or bus and wore a helmet the total points for that trip would be: 10 + 2.5 + 2.5 + 2.5 = 17.5
To create the bar graph, our system adds up all the points for the county and then divides by the population of the county [and then multiplies by 100 to eliminate pesky decimal points].
