Abstract

Mineral Dust, the most important type of aerosol, has a significant direct and indirect role in weather and climate. In this case, it intend to investigate the capability and capability of MACC model validated by MODIS for detection of dust episodes in the Kurdistan province during 2003-2012. To achieve that, we analysis satellite and model data using Man-Kendall trend and statistical tests. The results of the temporal distribution indicated that the mean Aerosol Optical depth (AOD) in 2008 was 0.36 and its lowest was 29.04 for 2004. In addition, average AOD in menthioned year was 0.036, 0.335, 0.385, 0.377 and 0.3368 for the cities of Sanandaj, Saqez, Ghorveh, Kamyaran, Marivan, respectively. The spatial distribution of AOD average in different seasons showed that winter and autumn had the lowest amount and spring, and summer season had the highest AOD. AOD's monthly spatial distribution showed that high dust belonging to April-August period to covers completely interested area.The results of the Man-Kendall test showed that the area had a significant positive trend in the spring season throughout the province and the summer season in the east of the province. Therefore, the spring season in the area known Extreme Season and June 19, 2009 between the five days of the dust extreme is as an extreme episode with an average AOD of 1.16 and a horizontal visibility of less than two kilometers that it have the highest and most widespread mineral dust. In general, the results of the MACC with multidimensional approach showed that optical depth (AOD, DOD) is a more appropriate criterion than horizontal visibility in determining dust storm.

Abstract


Along with the development of cities and increasing population, many challenges have been created, the most important of which is urban transportation. The inability of traditional urban management to address this challenge has led to some approaches, including intelligent transportation. Adopting and implementing such an approach in metropolitan areas requires a change in management approach, of which integrated urban management is known as the most important. The purpose of this study is to investigate the status of integrated urban management and then its impact on the realization of intelligent transportation in the city of Zahedan. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The validity of the instrument and its reliability was confirmed by Cronbach's alpha greater than 0.70. The statistical population of the study is urban experts in Zahedan. The sample size was set at 100 people. The result of the one-sample t-test shows that the variables of integrated urban management are significant at the level of less than 0.05. From the statistical point of view, the 7 variables of good governance, synergy, unity of urban command, context, interaction, organizational structure, and systemic perspective are not in a good situation and these conditions have caused the integrated urban management index in Zahedan to not have favorable conditions. Also, the significance of the test shows that the 5 variables of intelligent transportation, namely intelligent monitoring, intelligent payment, intelligent violation registration, intelligent information, and mechanized fleet management are significant at the level of less than 0.05. Significantly, it indicates the unfavorable situation of the intelligent transportation index in Zahedan. Regression showed that integrated urban management variables can be more than 68% effective in the realization of intelligent transportation and 32% are dependent on other factors. The variable of good governance with 12% and then the systemic perspective with 11%, has the greatest impact in this regard.

Keywords: integrated management, intelligent transportation, Zahedan city.
