“…MAVT is a well-researched and well-founded methodology, and a relatively simple MCDA method. Indeed, research in Multi Attribute Decision Making has suggested the use of simple, understandable and usable approaches for solving decision-making problems (Ulengin et al, 2010). Other reasons for choosing MAVT to complete the present methodological framework are as follows: (i) since it is founded on fundamental axioms of rational choice (e.g.…”

“…For the evaluation of sustainable transportation policy, an important research priority is the development of modeling and decision-making approaches from the system perspective (Ülengin, Kabak, Önsel, Ülengin & Aktaş, 2010;Fiksel, 2006), which focuses on interrelationships among components of the transportation system and treats the system's evolution as the result of interactions and feedbacks among those components. System Dynamics (SD), which was initially developed by Forrester from MIT in the 1950-1960s, is an -1712-Journal of Industrial Engineering and Management -http://dx.doi.…”

Abstract:Purpose: Targeting the problem of overloaded trucking regarding the Highway Transportation of iron ore from Caofeidian to Tangshan (HTCT), this paper aims to assess the long-term effects of alternative Truck Weight Regulation (TWR) policies on the sustainability of the HTCT.Design/methodology/approach: This paper develops a model for policy evaluation using System Dynamics (SD). The model, comprising six interrelated modules, is capable of simulating the effects of TWR policies on trucking issues, such as freight flow, truck traffic flow, pavement performance, highway transport capacity and trucking time. The model further sheds light on the Cumulative Economic Cost (CEC), including the transport cost and time cost of freight owners, and the Cumulative Social Cost (CSC), including the pavement maintenance cost, greenhouse gas emission cost, atmospheric pollutants emission cost and traffic accidents cost, so the effects of TWR policies on the sustainability of the HTCT could be evaluated. expected by the local government. To be specific, (1) if CSC is considered to be much less important than CEC, the local government should continue implementing TTP with the maximum overload ratio; (2) if CSC is considered to be much more important than CEC, then TRP is recommended; and (3) if CSC is considered to be slightly more important than CEC, TMP with an overload ratio of 80% is best. Practical implications:The conclusions of this paper may help the local government design appropriate TWR policies to achieve the sustainability of the HTCT.Originality/value: To the best of our knowledge, this is the first effort to evaluate TWR policies on the sustainability of the highway freight system based on SD.

“…At this point, sustainable transport system plays a great role (Ülengin et al [2], Hensher [3]). An environmentally sustainable transport system can be defined as "one where transportation does not endanger public health or ecosystems and meets needs for access consistent with use of renewable resources below their rates of regeneration and use of non-renewable resources below the rates of development of renewable substitutes (Browne et al [4]).…”

Urban transport has become a more significant source of the pollution of environment. The environmental problems have two aspects: local and global. Local environmental problems include air pollution and noise. As for instance, diesel engines are significant contributors to air pollution. Some of the basic types of exhaust have a strong obnoxious impact on live organisms. They include cancer-causing substances and also contain other harmful pollutants. Even if allelectric suburb railway transport does not have effect on air pollution, they are the source of noise pollution. From the point of view of a global environmental problem, a great part of total greenhouse gas emissions are mainly caused by urban transport, especially road transport. At this point, environment friendly urban transport systems have a crucial role in saving environmental quality.In our study, we start by presenting the main local and global environmental problems caused by urban transport. Our study focuses on İstanbul urban transport systems from environmental point of view. We present basic data about İstanbul's transport system and transport policy. This study uses a SWOT analysis to study İstanbul transport system from the environmental point of view. We analyze strengths, weaknesses, opportunities, and threats of the system and put forward recommendations. Finally our paper summarizes the experiences from İstanbul.
