“…Cities with vehicle ownership encouraged have a population of around 3 million versus 9 million inhabitants where ownership is not encouraged, however it appears that the larger city has a lower GDP per capita. Feng et al, (2009) propose a hybrid model which integrates system dynamics, cognitive maps, and a sensitivity model to study the problem of investment in transport systems and in particular the question of resource allocation over time or when to invest. A case study for Taipei is used to illustrate the approach to satisfying the needs of multiple stakeholders.…”

It is 20 years since Abbas and Bell (1994) evaluated the strengths and weaknesses of system dynamics as an approach for modelling in the transportation area. They listed 12 advantages of the approach and in particular suggested it was well suited to strategic issues and that it could provide a useful tool for supporting policy analysis and decision-making in the transport field. This paper sets out a review of over 50 peer-reviewed journal papers since 1994 categorising them by area of application and providing a summary of particular insights raised. The fields of application include the take-up of alternate fuel vehicles, supply chain management affecting transport, highway maintenance, strategic policy, airport infrastructure and airline business cycles and a set of emerging application areas. The paper concludes with recommendations for future application of the system dynamics approach.

“…We thus assume that energy consumption can positively affect environmental issues (CO 2 emission). The number of private vehicles and buses positively affects traffic congestion and energy consumption [17]. We assume that the number of city buses and the number of motor vehicles both positively affect traffic density and energy consumption.…”

We established a 30-year-simplified system dynamics model. We simulated the effects of various urban transportation management policies. Our proposed approach develops appropriate models in other cities. a b s t r a c tSustainability is an urban development priority. Thus, energy and carbon dioxide emission reduction is becoming more significant in the sustainability of urban transportation systems. However, urban transportation systems are complex and involve social, economic, and environmental aspects. We present solutions for a sustainable urban transportation system by establishing a simplified system dynamics model with a timeframe of 30 years (from 1995 to 2025) to simulate the effects of urban transportation management policies and to explore their potential in reducing vehicular fuel consumption and mitigating CO 2 emissions. Kaohsiung City was selected as a case study because it is the second largest metropolis in Taiwan and is an important industrial center. Three policies are examined in the study including fuel tax, motorcycle parking management, and free bus service. Simulation results indicate that both the fuel tax and motorcycle parking management policies are suggested as potentially the most effective methods for restraining the growth of the number of private vehicles, the amount of fuel consumption, and CO 2 emissions. We also conducted a synthetic policy consisting of all policies which outperforms the three individual policies. The conclusions of this study can assist urban transport planners in designing appropriate urban transport management strategies and can assist transport operation agencies in creating operational strategies to reduce their energy consumption and CO 2 emissions. The proposed approach should be generalized in other cities to develop an appropriate model to understand the various effects of policies on energy and CO 2 emissions.

“…They proved that FCMs are particularly useful for solving problems in which numerous decision and uncontrollable variables 596 C.-H. Hsieh et al are causally interrelated. Feng and Hsieh (2009) analyzed transport diversity via a hybrid model integrating system dynamics, FCMs, and sensitivity model to tackle the uncertainty, feedback interaction, and complexity of system relationships. Furthermore, the sensitivity model developed by Vester and von Hesler (1982) is employed for identifying the systematic role of each vulnerable factor.…”

The increasing damages and losses bring requests to improve coping capacities for extreme conditions on the identification of and improvement to socioeconomic vulnerabilities. Disruptions to critical infrastructure (CI) influence the capacities for resilience and sustainable daily operations both directly and by causing failures in one system that in turn affects other systems. Among the transportation systems widely identified as national CI that should be protected, ports provide substantial employment, industrial activity, along with national and regional development. This study thus examines the vulnerability of port failures from an interdependency perspective. Fourteen vulnerable factors are developed by literatures as well as in-depth interviews. Four international commercial ports in Taiwan are employed as empirical cases to evaluate port vulnerability through semi-quantitatively systematic methods, including fuzzy cognitive maps and sensitivity model, while geographic information systems are used to clarify the spatial-functional interdependency. In addition to the underestimated vulnerability because of omitted interdependency, analytical results reveal that capacity and efficiency significantly affect port vulnerability. Increasing local cargo bases and co-opetition are suggested to improve the port vulnerability. The proposed assessment framework helps decision-makers understand the interdependent vulnerabilities and adopt appropriate strategies for the mitigation of losses.
