摘要

The increase in production in some sectors of the Saudi Arabia's economy over the last three decades has transformed the economy from one of subsistence based on nomadic grazing and traditional agriculture into a strong, modern industrial economy based upon oil revenue and modern agriculture. This change in the economic base has resulted in a drift of population to urban areas, depleting the traditional rural economy of labour. The growth of the population and an increase in economic activity therefore require transportation systems which are able to facilitate the movement of both people and commodities. But when economic activity in a region depends on one type of transport we must examine the level of this network, for instance the Al-Qassim Region is solely dependent on its road transport network. The Al-Qassim Region is considered to be an agricultural area and the transport road network is an important element in the transfer of production both within the region and further afield. Furthermore, the Al-Qassim Region is a metropolitan area, according to a recent estimate; the population density is 12.6 people per square kilometer. This implies a high potential for urban sprawl in the region. To provide information about the ability of the existing road network to contribute to agricultural development, it is necessary to identify the level of transport road network in the Al-Qassim Region through the density and history of the road network.
