Abstract: This paper is a new look to an ``old theory called ``Thunens model, which is considered to be most relevant to agricultural economy and economic geography. Accordingly, reviewing the model using graphical representation is worthwhile. This unique approach to look at Thunens model leads to a better understanding of the model in a simplistic way, as well as to highlight the relevance of the transportation system regarding cost. In fact, this paper is an innovative approach of looking at Thunens model in such a way as to prove that Thunens model is also rather a ``transportation model. Towards the end of this paper, an example from Saudi Arabia in context is presented to testify how Thunens model is closely to related to transportation.

Key words: Thunens model, Transportation, Transportation cost, Transportation rate, Agriculture land use.
