Modelling and land use transportation interactions has become an important aspect of road design transport planning. On the one side, for example, design roads in urban centers, it can increase land use and it can also reduce employees or students catching buses or driving cars' time spending to go to workplaces or schools users. Hence, the land use and roads designing transportation can give benefits to residents and employment people to reduce time to wait buses or taxies etc. public transportations to go to workplaces or schools or shopping centers etc. anywhere. It seems to assist bus companies or taxi drivers to earn more income, On the other side, designing urban transport systems is also important . Increased densities mean more destinations become within convenient walking and cycling distances and consequently the use of these modes tends to be higher. Also in dese cities public transport systems are able to offer higher levels of service and operate more economically, when the provision of sufficient road space to meet potential demand becomes impractical. It aims to reduce the danger of driving or walking in urban areas. The transport modes ( that is walking, cycling, public transport) and the extent of car dependence is less, due to driving users dependency is less on rural roads. Hence, building main roads can concentrate on designing convenience to pedestrian walking to close to their houses on the streets. However, poor transport design and land use can cause to spend too expenditure not only transport costs on governments and transport users both and also the costs of providing other services. These include the usual utilities and also education and health services as well as negative externalities, such as greenhouse gas emissions. Most such studies concluded that there are significant financial and economics cost advantage of inner city redevelopment compared with fringe development. However, such policies won't necessarily be successfully, in particular because of the two ways road problem, they may result in additional private investments and employment opportunities flowing into the region, buy may equally result in population and employment opportunities flowing out of the target region because of the improved access to other centers. However, CI can be an extremely useful way to manage operating costs. Because CI is a function of both fuel and non-fuel costs. It is important to use it appropriately to gain the greatest benefit. Appropriate use varies with each airline, and perhaps for each flight. How low fuel situations can bring less fuel consumed benefit in the more environmentally friendly flight? Fuel conservation strategy can help airlines significantly reduce operating costs. However, many operators do not take full advantage of this powerful tool. Cruise flight is the phase of flight that falls the largest percentages of trip time and trip fuel are consumed typically in this phase of flight, which also impact trip time and fuel significantly can often be avoided through appropriate cruise planning. This fuel conservation strategy includes these characteristics. These objectives which depend on the perspective of the pilot, dispatcher, performance engineer, or operations planner can be groups into five categories, such as:
