Abstract

The interaction between urban land uses and urban transportation system is one of the most important issues in traffic policy and urban management. In order to investigate how these land uses interact with the transportation system, the construction effects of “Tehran Mall” trans-regional complex on the general measures of Tehran transportation system and its District 22 are studied based on the 4-step modelling approach. In order to modeling the travel attraction of this complex, models of mixed trans-regional land uses are calibrated using volume counting and query information. Then, two scenarios are defined for Tehran in the year 1400. The first scenario is the status of the Tehran transportation system in absence of Tehran Mall and the second one its status in presence of Tehran Mall. After modeling both scenarios in EMME software, a comparison between the two scenarios is performed based on the general measure of the transportation system, which include transportation network measures, auto and public travel demand, air pollution emissions and fuel consumption. Comparing the results of these two scenarios shows that in the case that Tehran Mall is constructed, important measures of Tehran transportation system improve. It can be concluded, therefore, that the construction of a trans-regional attractive land use in an area with unsaturated traffic capacity can attract part of the travel demand from other areas, and so can improve the transportation system while reducing emissions.
