In the current century, the escalation of issues such as population growth, urbanization, people's demand for housing or work in a particular place, and the prevention of urban expansion, ... are among the factors that have highlighted the increase in building density in cities. Therefore, this process must be progressively accomplished, so that the infrastructures necessary for this process could be provided in parallel. However, the determination of the density in Tabriz metropolis, has been done regardless of the infrastructure of transit network, so that this has failed to meet the population's traffic needs and heavy traffic in this metropolis. In this study, the feasibility of increase in the density of building with respect to the passages’ network acceptance capacity of Tabriz metropolis has been investigated in Bahār neighborhood of this city. To achieve this goal, the identification and determination of the points of the passages’ network which face with shortages or surplus capacities have been dealt with, by estimating the volume of traffic in each passage of the study area, to determine areas with excess density and areas with potential of increasing density, at the scope of the study. Data of this research have been collected using field studies and to analyze these data, AIMSUN and ARCGIS software have been used. The results showed that the main passages in the study area have a traffic problem, so that the volume of transit traffic through the study area by itself puts the passage level at the threshold of C level (desirable urban service level). Also, the production traffic load alone and apart from transit traffic load provides a level C service, since it is not possible to separate transit and production traffic in the short term without developing arterial network and modifying the passages’ network around the neighborhood. Therefore, the Bahār neighborhood has been saturated, considering the passage reception capacity and does not have the capability to increase the building density.
