When talking about sustainability, it means what we are currently doing and developing in the present must not sacrifice the next generation of human being in the future. Transport is crucial to development. Basically, people move to fulfill their needs. In order to move, access is needed. Without access to places where people can meet their needs, the quality of life degenerates. Inappropriately designed transport strategies and programs can result in the poor environment condition, lack of economy profit, and exceed the capacity of public finances.
In order to be effective, transport policy must satisfy three main requirements. First, it must ensure that a continuing capability exists to support an improved material standard of living. This corresponds to the concept of economic and financial sustainability. Second, it must generate the greatest possible movement improvement in the general quality of life, not merely in increase in traded goods. This relates to the concept of environmental and ecological sustainability. Third, the benefits that transport produces must be shared equitably by all sections of the community. This we term social sustainability.
The rapid growth cities in developing countries has seriously compromised existing transportation systems and significantly increased the challenge of creating future transportation system. It is indeed in developing countries that the greatest growth in private motorized vehicles has been seen in the past few years and is expected in the future, primarily in urban areas. In order to reach sustainable transportation, developing countries must create a rapid, affordable, low-cost construction, and environmental-friendly transportation system in the downtown which is integrated with the suburbs. We need to dare to create transport system which giving priority to the needs of the poor majority rather than the automobile owning minority.
Show your guts. Yes, we have to dare.
