Id like to think that similar statistics would apply for all cities but I think in a city where the major form of transport is cycling, rather than driving, its not surprising driving has a negative affect. And I'm sure in a car focused city the opposite may be found.The study also concluded that 68% of residents bicycle at least once a week, and citywide, 35% of residents bicycle to and from work/school, more than any other transportation method.
When taking trips of under 6 miles, bicyclists outnumber cars 3 to 1. And most commuters cycle year-round, even with an average low of 28-degrees Fahrenheit during snowy winter months and 2.5 inches of rain during summer months.
Im sure Mr Kjedldgaard was happy with the statistics. (information was found at http://sustainablecitiescollective.com/)
