Abstract:

Urban expansion during recent decades has led to the increasing distance between the origins and destinations of trips within metropolitan areas. Therefore, using the motorized modes of transportation has become a must. Adequate accessibility to the job, educational and welfare opportunities can be mentioned as services of a proper urban life.

Accessibility of the low income households to these opportunities depends on public transport services. The goal of this thesis is to evaluate facility distribution approach based on the distance distribution of citizen’s need throughout Isfahan city as the equity assessment of public transport services distribution.

In the current study, in each Isfahan traffic zone, populations without private vehicle were calculated. Thereafter, by developing the meaning of connectivity, the public transport service supply in each city zone was evaluated. Using Gini’s coefficient and Spearman’s correlation coefficient, coordination between demand rate of public transport services and supply rate of these services in Isfahan’s different zones were assessed. Due to the expansion of bus rapid transit and a part of phase 1 of Isfahan’s subway, analysis of three conditions (cases), base (before launching of bus rapid transit), current (launching of line one of bus rapid transit and a part of line one of subway), and horizon (completion of bus rapid transit and line one of subway) were carried out. Also, analyzing the facility and supply were carried out based on two approaches of not considering the possibility of transaction (exchange) between adjacent stations and considering this possibility. Results for Isfahan are as follows: for the condition of not considering the transaction possibility, Gini coefficient and Spearman coefficient for each condition, respectively were as follows: 0.31 and 0.18 for the base condition, 0.33 and 0.18 for the current condition and eventually, 0.335 and 0.22 for the horizon. Also, for the condition of considering the possibility, Gini and Spearman coefficients respectively were as follows: 0.397 and 0.151 for the base condition, 0.338 and 0.155 for the current condition and eventually, 0.146 and 0.22 for the horizon.

Isfahan’ zones with priority were specified for amplification of public transit services. Results indicates that equity of distribution between demand and supply throughout the Isfahan is comparable (appropriate) compared to the evaluated cities all over the world, but resent development process of Isfahan’s public transit wasn’t along an equity distribution between demand and supply.
