Travel need not always be a burden that requires time and effort. Travel can also be a way to enjoy oneself and to gain needed exercise for health. Travel also does not have to require high financial costs on the part of either government or individuals, or to be harmful to the environment. In particular, WBB promotes the importance of rail as a means of connecting cities; car control as a way to reduce congestion and make available needed space for other travel modes and other aspects of life; public transit as an efficient way to move people within cities; and walking, cycling, and rickshaws as urban-friendly modes of transport that are good for health, the environment, and employment.
