The main aim of this work was the definition of a transportation planning methodology that was synthesized and less expensive than the one presented by the traditional process, and, more than this, which could be done without household research. A superficial analysis of several works was conducted, and four of them were chosen for a more detailed analysis, which allowed to define the proposed methodology. The method is based on the determination of trip production and trip attraction once the number of houses, shops, offices, industries, etc. present in the area of study is known, as well as their respective characteristics, and transferable rates from other studies were used. It follows the four steps model, where the fundamental difference is that, because complete data were not available, once household OD surveys were not performed, several adjusting procedures were performed, to verify the degree of compatibility of the used transferred taxes. The work is limited to traffic assignment in the road network for the base year, and to the comparison with the observed flow, and it was verified that the process leads to an acceptable result.
