Abstract
In the 21st century, the world population is growing at a spiraling pace. Much of this growth is occurring in developing countries, where access to food, sanitary water, education, and health is severely limited. The ever-increasing urbanization highlighted the need for sustainable development based on human-environment interaction. The excessive and unplanned expansion of cities has resulted in numerous environmental predicaments due to clearly emphasized economic issues at the expense of social and environmental concerns. The most significant features of megacities are indicated in this paper and the environmental, social, physical, and economic criteria are addressed in order to attain...
Assessing the Injury Severity of Urban Bus Crashes Toward More Sustainable Cities: A Case Study of Isfahan, Iran
, M.Sc. Thesis Sharif University of Technology ; Kermanshah, Amir Hassan (Supervisor)
Abstract
Traffic accidents around the world kill a large number of people every year, and their lightest consequences are temporary disabilities for citizens. According to the statistics, the number and severity of accidents have been growing, due to the expansion of cities and the human population there, and this increases the need to pay attention to traffic safety. One of the substantial subcategories of traffic safety research is public transportation. However, limited studies have been done in this field. One of the main modes of public transportation are buses, which bring more risk of accidents to passengers, due to their size and higher passenger capacity compared to passenger vehicles....
Predictive Cordon Pricing to Reduce Air Pollution
, Ph.D. Dissertation Sharif University of Technology ; Poorzahedy, Hossain (Supervisor) ; Lindsey, Robin (Co-Supervisor)
Abstract
Traffic is a major contributor to emissions in many large cities with severe air pollution. Experience in London, Milan, and Stockholm shows that charging for the use of roads can be effective in reducing emissions, as well as congestion. This study examines the use of predictive cordon tolls based on weather forecasts to reduce ambient air pollution and congestion. Travelers choose their destinations inside or outside the cordon, and whether to drive or take public transport. Passenger vehicles are divided into three classes according to their emission characteristics, and higher tolls are imposed on more polluting vehicles. The Box model of emission dispersion is used to predict air...
A resilience-based practical platform and novel index for rapid evaluation of urban water distribution network using hybrid simulation

Abstract
This article proposes a novel index along with a user-friendly platform for resilience evaluation of the urban water distribution networks (WDN). WDN is of great importance in preserving the safety and sustainability of communities and cities. Resilience of a given system results in its sustainability. In recent years, many studies have focused on resilient urban WDN. However, these studies did not provide a comprehensive evaluation index and platform that could simultaneously consider hydraulic analysis, resilience parameters, and significant uncertainties. In this study, a novel resilience index was defined, and a user-friendly and practical platform (REWAT) was developed to calculate the...
Reducing traffic congestion and increasing sustainability in special urban areas through one-way traffic reconfiguration
, Article Transportation ; Volume 49, Issue 1 , 2022 , Pages 37-60 ; 00494488 (ISSN) ; Ghadirifaraz, B ; Shetab Boushehri, S. N ; Hosseininasab, S. M ; Rafiei, N ; Sharif University of Technology

Abstract
In the contemporary sustainable urban set up, one of the critical issues adversely affecting the quality of life in urban areas and inflicting immense costs on cities is traffic congestion. Traffic congestion is an outgrowth of increased traffic flow in certain locations of large cities. Recently, urban decision-makers and transportation planners resort to one-way traffic system as an effective traffic management strategy, which has a profound effect on reducing traffic congestion and improving traffic flow, leading to urban sustainability. In the present paper, the authors endeavored to develop a novel methodological framework based on optimization techniques in order to mitigate traffic...
