assessment of objective accessibility to public transportation stations (A case study: Tehran city)

This study was conducted with the main goal of evaluating objective access to public transport stations in Tehran. The research method is quantitative and analytical. Arc Gis software and Network Analysis Extension was used to analysis technical dimentions. The results shows the access area based on the street network, 800 meters for metro and BRT stations, and 400 meters for the bus, although, public transportation stations cover about 50 percent of the city’s area, but they covers more than 71 percent of the population at the intervals. Also, the results indicate that there is a large difference between the different zones of the city in terms of access to public transportation. In terms of covered area, zones of (11, 12 and 8) with more than 89 percent of coverage, and zones (22, 21 and 9) with less than 27 percent of coverage, are the highest and lowest, and for the covered population, the zones of (11, 8 and 12) with more than 89% coverage, and zones (9 and 1) with less than 40% of coverage, respectively, are the highest and the lowest available population to public transport stations. In general, the areas located in the central area of Tehran have a favorable situation relative to the peripheral regions in terms of access to public transportation, especially the subway and the BRT. Hence, in the context of public transport development projects, priority should be given to peripheral areas
