In the UK, the number of people combining bike and train journeys grew explosively from 19.5 million in 2007 to 28 million in 2009. An explosive increase.
Why? Any orthodox economist will tell you that people make decisions based on incentives. Read the above article and you see two positive incentives at work:
1) Train companies have fixed a policy of carrying folding bikes to be carried for free. Hence the rapid rise in the number of folding bikes being used by commuters. And
2) Stations are increasing their bicycle parking spaces. “There are now around 25,000 cycle spaces in the UK, with thousands more planned.” Hence the number of people parking at stations is also increasing.
(Of course, rising petrol prices are another incentive to bike.)
Both of these actions send out signals that bicycles are welcome at train stations (although in part restricted to folding bikes on the trains themselves). Although this isn’t going to cause a mad rush of people biking to the station, it will cause some to think. And some to bike. And as more people bike, it becomes more acceptable. And, like a slow-rolling snowball, grows.
