In any country, road transportation improvements don't guarantee increased economic development. To increase economic development, an improvement needs to assist any lorry drivers to drive in short trips to reduce transportation costs and shorten time driving on the road or to make transportation more reliable, e.g. reducing the numbers of traffic jams on any roads. A proper economic climate must also exist as well as other support services. With these factors to influence transportation improvements can become catalysts for economic expansion. However, road transportation improvement that intends to induce job creation, when employers need many lorry drivers to help them to transport products and to move products on the roads often. So, the employers need to employ many transportation workers and lorry drivers to help who to transport their products to send to clients, due to the transportation time is shorten and work efficiency is raised, so the transportation times are also increasing every day when the road transportation roles are improved. On the other side, improving transportation can raise productivity when many customers need to buy many products and the lorry drivers may drive whose lorries to transport many products between factory and office or between factory to the client's home or between the shop and the client's on the road in the short time fast. I recommend one model links in an overall road transportation network includes these four modes.I.Maximizing use of the existing road highway system.II.Extending or improving the multi-lane divides system local roads and connectors.III.Continually improving the entire road highway network in response to business activities demand. The improvement of modern road transportation successful factors include: ⦁How to improve the highway networkmodernization includes obsolete interchanges and other segments of the road, transport network of new designs to improve the life and service of pedestrian walking streets, rebuilding certain in main or minor roads. To the extent that labor markets operate more efficiently and more jobs are created to raise economic expansion if our governments can improve road transportation system to design to satisfy business users demand when lorry drivers need to move or transport whose products on the streets, but who will not influence pedestrian are walking on the streets. Hence, excellent transportation design network can subsequent plan efforts, it can also rise economic efficiency, community and social effects, it can also encourage transportation users to attempt to drive lorries to transport products a lot of times in one day fast and who can also avoid traffic jams occurrence on the road easily. On the one side, economic development is a concept referring to the material aspects of community welfare. There are numerous factors need of development: growth in income and wealth, equitable distribution of income, decreased infant mortality rates, increased literacy rates. On the other side, economic growth means which is sustainable increase in community income and /or wealth. ( wealth is the net of resources that generate income). It seems the link between transportation facilities and economic growth has close relationship. Good transportation facilities support economic growth by lowing the transportation costs of users of the transportation network, such as roads. Direct users benefits are reductions in travel, times and fuel consumption, increased reliability and increased safety in the movement of people and products, users' transportation costs are reduced, resources are used for other purpose.
