Motivation … route type matters

Source: Winters et al, 2011 7

Top motivators Route ease & enjoyment •  separate from traffic for

the whole route •  beautiful scenery •  gentle slopes •  faster than other modes

Top deterrents

Route safety

•  car, bus & truck traffic •  vehicles driving faster than 50 km/h •  motorists who don’t know how to drive safely near bikes •  risk of injury from car-bike collisions

separated bike lanes “cycle tracks”

“Both Oulu and Copenhagen have extensive networks of cycle tracks and dedicated bike paths, which made the ride easy.

But something else was also different. It took a while for me to figure out what, but I eventually realized that I had relaxed. Unlike riding in Calgary, I wasn’t on constant lookout for cars

getting too close for comfort.

I could feel the difference in my gut.”
