![]() Road needs are closely associated with the relative location of centres of population, commerce, industry, and transportation. The process follows several steps: assessing road needs and transport options planning a system to meet those needs designing an economically, socially, and environmentally acceptable set of roads obtaining the required approval and financing building, operating, and maintaining the system and providing for future extensions and reconstruction. Ideally, the development of a major road system is an orderly, continuous process. To this end, road managers must be concerned not merely with lines on maps but also with the number, type, speed, and loading of individual vehicles, the safety, comfort, and convenience of the traveling public, and the health and welfare of bystanders and adjoining property owners. Long-term solutions require the provision of alternatives to car and truck transport, controls over land use, and the proper pricing of road travel. Often the building of new roads to alleviate such problems has encouraged further urban sprawl and yet more road travel. Road needs have been strongly influenced by this popularity and also by the mass movement of people to cities and thence to suburban fringes-a trend that has led to increasing travel needs and road congestion and to low-density cities, which are difficult to service by public transport. Since the beginning of the 20th century, as the automobile and truck have offered ever higher levels of mobility, vehicle ownership per head of population has increased.
