PTW mobility and use

It is estimated that there are 313 million PTWs in the world, with a relatively uneven distribution across regions 77% are found in Asia, 5% in Latin America, 1% in Africa, 1% in the Middle East and 16% in North America and Europe [ROG 08], This disparity is also characterized by the uses made of this mode. Primarily recreational in North America and Australia, the two-wheeler does have a much more mixed function, for example, in Eiffope it is increasingly used to escape the problems of urban traffic congestion in other regions of the world it may have a mainly utilitarian use. 

In most OECD coimtries, over the past decade (2001-2010), the motorcycle fleet has grown much more rapidly than the passenger car fleet (see Table 7.1). 

PTWs are becoming an important component of the transport system and represent in some cities up to 30% of the motor vehicle fleet [ACE 13], They present both assets for mobility, and also challenges in terms of traffic management and safety. However, only a few countries have in place a national transport strategy for PTWs (e.g. [DFT 05, VIC 08]), though several measures may be taken at the local level.
