A multi-criteria model for evaluating sustainable transportation system in West Sumatra

Abstract

Sustainability has become a major concern for transportation planning and policy around the world. This study develops a multi-criteria model to evaluate the sustainable transportation system in West Sumatra. A literature study is carried out to identify the indicators and then validated by the experts. As a result, a total of sixteen indicators divided into six indicators of the economic aspect, five indicators of the social aspect, and five indicators of the environmental aspect are proposed as the indicators of sustainable transportation evaluation. Next, the relationships among the indicators are determined using the Interpretive Structural Modeling (ISM) method. The results show that six indicators consist of accessibility of region, management of public transportation, the infrastructure of public transportation, transportation for people with special needs, level of traffic congestion, and land use to improve transportation facilities identified as the most influencing indicators. On the other hand, passenger convenience is suggested as the most dependent indicator. The importance weight of indicators is then determined using the Analytic Network Process (ANP) method. The land use to improve transportation facilities is regarded as the most important indicator, followed by the level of traffic congestion, and transportation for people with special needs. The model is expected to help the policymaker in improving the performance of a sustainable transportation system.
