Share of Cycling over the Total Amount of Trips, mid 1990s

In many countries cycling has become part of the urban planning process. Many public transit systems have park-and-ride facilities for bicycles and many roads have reserved bike lanes. Consequently, cycling accounts for a significant share of the total amount of trips, over 25% for the Netherlands and around 15% for Japan, Denmark and Switzerland. For the United States, this share is less than 1%. Geography plays an important role in the usage of the bicycle as a mode of transportation, particularly in terms of the landscape (flat land) and climate (excessive temperatures).
