A road transportation network system considering as an aspect of spatial organization will first look. Roads are important for transport of goods and passengers for short and medium distances. Roads link directly to places of employment, manufacturing plants, distribution centers and retail outlets within communities. The road network is therefore an essential element of the multi-modal transportation system that provides for the movement of people and goods. Without a network of connecting roads, other modes cannot provide complete trip making.

However, the relationship between these transportation facilities and services and how the trip type and travel mode choice is made for moving both people and goods also shapes and influences the future demand on the area transportation system.
