Abstract

Transportation is an integral part of the human life. Transportation facilities support the human activities related to the distance, location, and mobilization of goods and people. Nowadays, Padang people need a safe, convenient, and fast transportation system. However, like other big cities in Indonesia, Padang is also facing the transportation problems caused by the increasing of population as well as increasing of the amount of vehicles. The transportation system in Padang city generally doesn’t meet the sustainability criteria yet as it can be seen from the low quality of roads, increasing number of accidents, high traffic, fuel wastage, increasing pollution, low quality of public transportation, and incomplete of road facilities. Therefore, Padang city requires the sustainable transportation planning assessed based on the appropriate indicators. In this research, the initial indicators are identified and derived from literature and validated by experts. As a result, sixteen indicators consist of six economic indicators, five social indicators, and five environmental indicators have been proposed as the indicators of sustainable transportation. Interpretive structural modeling (ISM) methodology is applied to develop a network structure model of the indicators. The results show the social indicators are regarded as the basic indicators, while the economic indicators are indicated to be the leading indicators. Of those indicators, accessibility of region, management of public transportation, infrastructure of public transportation, level of traffic congestion, land use to improve transportation facilities, and transportation for people with special needs are regarded as the most influencing indicator. The ISM model hoped can aid the policy makers by providing a better insight in developing the sustainable transportation in Padang city.
