An Analysis of the Role of Urban Density in Transportation (A Case Study of Ilam)

High-rise building and spatial developmental strategy in height as a result of population growth and the lack of suitable land for the building of recent decades have increased particularly in large cities. In Ilam, like most cities in Iran, the most important political and commercial centers are included in the center of this old city. The central part of the urban structure and distribution have always attracted travelers because of large amount of attractions. In this study, the functional effects of the building density on the transportation network in central context of Ilam have been analyzed. This study using developmental-functional approach and a combination of research methods (descriptive, analytical and field study) investigates this issue in Ilam. For analysis of the findings Visio, Crafer, and ArcGis software have been used coupled with entropy technique. The results of the research revealed the weaknesses in access, the inappropriate structure of the urban transportation network, the spatial position of utilization, the excessive building density in the old urban texture, the failure of the public transportation system, and the inconsistency of pedestrian traffic and vehicles in the urban structures in Ilam.
