Abstract
To resolve environmental and social problems and traffic congestion, a sustainability evaluation of transportation infrastructure should be done for current and proposed situations. The aim of the present investigation is to evaluate the sustainability of infrastructure project on system interchange and assess their results with respect to sustainable development indicators. Based on interviews with experts, intensive observation, and development infrastructure related to the case study, six proposed scenarios are proposed to improve traffic condition of the Sheikhfazolah-Yadegar interchange in Tehran. The proposed scenarios are modeled and calibrated in AIMSUN 8.0, then the value of all indicators are determined through an indirect and direct procedure by AIMSUN results. A technique for order of preference by similarity to ideal solution (TOPSIS) method is used to integrate the results of proposed indicators. Although the weight of each indicator specifies its effect in sustainability evaluation, changes intensity of indicator value was not applied in sustainability evaluation by the previous methods of multi-criteria decision analysis (MCDA). In this study, for the first time, a simplified approach is defined and used to evaluate sustainable development of all scenarios that can apply the effect of changes intensity in sustainability evaluation. This method is named the applied effect of changes intensity in each indicator (AECIEI). According to the purposes of Tehran vision in 2025, all proposed scenarios are ranked based on TOPSIS results and the simplified approach, and then results of these methods are compared.

Summary
Transportation system is largely recognized having significant externalities affecting environment, society, and economy. Several externalities positively affect people lifestyle, in terms of economic growth, increase in educational opportunities and in land value too; transportation opportunities enhance the quality of life by providing mobility and physical access to resources, goods, markets, and other amenities [1,2]. Negative externalities affect in terms of air and noise pollution, energy consumption, traffic congestion, cost of living, and traffic crashes with direct negative consequences on public health, welfare, and people wellbeing. These negative aspects are clear in mega cities characterized by a growth rate of population. Public Health 2020, 17, 435; doi:10.3390/ijerph17020435 www.mdpi.com/journal/ijerph
