The Analysis on the Road Pricing in the UK - Essay Example transportation modes interact in our analytical scheme, cite factors that influence our efforts to arrive at a workable solution, and then discuss other alternatives. Walking is the simplest means of personal mobility, and when the purpose of such action is to move from one place to another, it is known by another term: transport. Mobility and transport depends on several factors ranging from the anatomical, like having two legs, to the external, like having a path on which to move or transport one’s body. Mobility and transport have been amongst the important factors that determined human development, and whether we like it or not, these are subject to the economic law of supply and demand. The development of transport supply and demand has given rise to the complex system of transport infrastructures, modes of transportation, and the propensity for personal mobility we enjoy today. We take mobility as part of a natural ability to be where we want to be, and take it against our privilege any obstacle that restricts this freedom in any way. This is why transport has become subject to the laws of supply and demand, for whereas the demand for mobility continues to increase with human development the supply of transport infrastructure that makes it possible is limited. Fig. 1 shows the effects of developments in transportation in increasing the speed of mobility. Economists (Rodrigue et al., 2006) define transport supply as the capacity of transportation infrastructures and modes, generally over a geographically defined transport system and for a specific period of time. Transport demand is the expression of transport needs, regardless of whether those needs are satisfied fully, partially, or not at all. Both are commonly quantified in terms of capacity (infrastructure), frequency (services), and networks, as in the number of passengers, volume (liquids), or mass (freight) that can be (supply) or needed to be (demand) transported per unit of time and
