An investigation on the social and traffic effects of metro stations on neighborhoods

Neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. traditional neighborhoods of iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. in the modern era, the new master plans and the complementary local plans have disintegrated these neighborhoods both physically and socially. while old traditional neighborhoods were destroyed and new car oriented streets and highways have disrupted the traditional neighborhood life, the introduction of metro stations have provided a nucleus for neighborhoods around which urban space and social activity could emerge once more. in this respect, the attitudes of residents towards metro stations are very important. this study focuses on the social attitudes and the evaluation of traffic impacts of metro stations on adjacent neighborhoods. therefore, the changes in traffic patterns as well as social characteristics and residential satisfaction levels in two neighborhoods adjacent to metro stations are studied through a questionnaire survey. the results show that despite the potentials provided, metro stations had adverse affects on both social integration and residential satisfaction levels. they also adversely affected neighborhoods in terms of traffic flow through increase in local traffic, demand for parking, and increase in noise pollution. lack of attention to the new potentials turned them into threats and weakened the already damaged neighborhood structures..
