Studying influences of Valiasr non-level crossings on improvement Sari people lives

Abstract. Urbanism development, ever increasing usage of private vehicles, and limitations in developing network communications has increased traffic congestions, especially in metropolises. These problems impose burden costs on user, and in case of lack of appropriate response would have negative effect on other aspect of society. Due to traffic overlapping in urban level crossings, these categories of nodes usually accounts as one of full-accident urban passageway, especially in metropolis, like state capitals. As a consequence, available level crossings would be saturated and lose ability of covering traffic and complete handling for travel volume demand in all regions. This study has conducted with the aim of identifying amount of influences of constructing non-level crossings in improvement of traffic situation and thus, on sari people quality lives. This research is descriptive-analytical one and has conducted by self-built questionnaire and field study. Research variables consists influences of constructing this crossings of fuel savings, real price changes around crossings, facilitating citizens accessibility trends toward neighbor streets, operational performance changes (residential, business) around this crossings and decreases in accidents, which have tested using SPPS and non-parametric binominal-test. Statistical population of this research were all citizens of Sari, among them 384 samples have chosen and quarried directly using Demorgan table and simple random method. Results of this research showed that in view point of participants of this study, establishment of this crossing couldn't have positive and significant influences on air pollution decline, time savings, sound pollution decrease, urban perspective improvement, traffic fluent in around streets.
