During the phase of preparation of new masterplan, urban planners have no scientific tool/criteria to calculate and to find the optimum value of road network area. The aim of this paper is to identify a calculation basis (design models), to be used during the design of new masterplans, and during the assessment of the road network in any city/town based on transportation demands (trip generation in the area).A new vision in urban planning can be represented by indicating the volume over capacity ratio (V/C), for each section of the roadway network in each LandUse, by identifying the mathematical proportionality of road surfaces, relatively to LandUse areas and population, relating these 3 factors based on the V/C ratio required, depending on trip generation rates and landUse types.These models can be identified by establishing mathematical models analogously related to the “Distribution of neurons in Mammalian Neocortex”.
