Traffic Problems A Solution

The foregoing leads to somewhat confusing and contradictory conclusions. On the one hand, in many parts of the world (such as developing countries, countries in transition) the primary goal still is to design and construct new roads. This is a main condition for economic expansion and the upgrading of social facilities. On the other hand, in other parts of the world (notably in densely populated, developed countries) disadvantagous side effects of the growing traffic flows become more and more apparent. It is also quite clear that neither the side effects nor the growing demand can be neglected: No country in the world is rich enough to permit a continuously congested traffic system.

Therefore, all over the world, physical planning and improvement plans for the rural road network are necessary to provide for people's needs in the future. Simultaneously, however, harmful effects of this network conflict with the principles of environmental sustainability. In practice, planners must search for solutions. It is quite clear that the kinds of solutions will differ with the circumstances, such as the land uses to be served, population density, possible alternative solutions, other lands uses that are affected, opportunities for mitigation, and compensation for side effects. Obviously, these are great challenges for planners [13].
