For a more harmonious development between economy and transport and for a close relation supply and demand for travel, proper scientific studies should be conducted to determine operational instruments for resolving the contradictions between this report and especially those technical instruments should__ampersandsignnbsp; rovide recommendations on permanent and long-term planning that preceded the decision and policy-makers. One of these instruments that are in use with much interest and after 50 years are mathematical models in transportation. They are based on the assumption that a linear equation could represent the relationship between a dependent variable __ampersandsignldquo;Y __ampersandsignldquo; that represents a pointer or economic phenomenon and one or more independent variables __ampersandsignldquo; X , X ....X p 1 2 __ampersandsignldquo; and that each of them taken separately can satisfy the assumption of linearity that is expressed in mathematical form as follows, y F a a X a X a X e n n ? ? ? ?. ? ?...... ? 0 1 1 2 2 (1.0) It is important that we have implemented practical use of information which is part of a database system for collection and data management of travel and road traffic in our country. In particular and very carefully, we have also defined specific requirements for input data analysis and have made their selection for the purpose of constructing the model.
