Achieving environmental quality criteria is not possible without considering the pattern of physical development. The quality of the place is one of the effective causes in the occurrence of various diseases, however, regarding specific diseases such as cancer, the studies conducted are in the first steps. The present study tries to measure the spatial patterns of cancer deaths in Mashhad and show that 1) What is the pattern of deaths? And 2) to what extent is it related to the quality characteristics of the environment? The study is descriptive-analytical and the study variables include 1) characteristics related to the deceased and 2) characteristics related to the quality of the environment (including air pollution and green space per capita). For this purpose, after developing a conceptual research model, by receiving information related to the deceased and the quality of the environment, a spatial database was created in the ArcGIS software environment. In the next step, using classical statistical models (correlation and t-test) and spatial statistics (spatial autocorrelation, orientation and spatial regression) data were analyzed. The results showed that the spatial pattern of the deceased did not follow the pattern of population distribution and the difference in the spatial pattern of the deceased according to gender and their average age at the neighborhood level. The use of spatial autocorrelation models showed two hot cores in the north and southwest of Mashhad and a cold core around the holy shrine. Which shows the need to pay attention to spatial differences. The results of correlation and spatial regression test indicated that the frequency of deaths in the neighborhoods is related to the average level of air pollution and green space per capita. However, the need for further studies at various intervals is suggested to confirm the findings.

In compare to driving, cycling and other transportation modes, people pay more attention to their surrounding and connect with the environment while they are walking. Therefore, urban elements closed to the walking paths should be considered as very important elements. Pedestrians, while talking and shopping, accept more impacts from the environment and its characters than any other occasions. Separating the pedestrian spaces from roadways and streets can decrease the effects of noise and environmental pollutions and finally improve the issue of commuting in the city. The present study focuses on designing and constructing five pedestrian zones in metropolitan of Tehran and investigates their functions on urban structure. In the present study, attention is paid to five pedestrian zones of Tehran metropolitan to investigate their effects on urban structure. To do this, the emphasis of the present study is on changes occurred in three criteria including: “urban commuting space”, “green space and environmental health”, and “urban identity”, after construction of the pedestrian zones. Main required data were collected from the questionnaire designed and completed by the local businessmen community and pedestrian zone users. Field and documentary data were used as well. The sample included 350 questionnaires selected by Cochran formula. The results indicated that the studied areas have already moved towards a homogeneous situation due to the construction of pedestrian zones. Also, in one-way analysis of variance, five pedestrian zones showed a significant difference of improvement among the criteria, which means that there is a functional difference between some of them.
