Methodology and tools for sustainable urban transport planning
Sustainable urban transport planning has been frequently disscussed recently. However, to implement in practice of Vietnam, it is necessary to seek a new approach that enables integrating sustainable development goals into transport planning. The paper puts forward an assessment on the traditional approach to transport planning that is known as a forecasting method. This method is often utilized to predict the future on the basis of analyzing the current situation and thence forecast the trends for the future development. However, according to this approach, many current trends are not oriented towards sustainable targets in the future. Backcasting is a new methodology for planning through setting up the scenarios. Backcasting allows inserting the sustainable goals into transport planning, such as the suppositions about scenarios of mitigating greenhouse gas emissions caused by urban transport vehicles. Thereby, backcasting will define the tasks and actions that need to be carried out at the present time to bridge the gap between the current situation and the desired future. The paper introduces Vensim software, as a scenario prediction tool is which currently being used in research project to improve the traffic condition in INSA-Lyon's campus aiming at studying sustainable environment. This could be a pretext for discussion on necessity of changes more strongly the methodology in transport planning in Viet Nam.
