Analysis on the motivation factors affecting daily mode choice of mandatory and non-mandatory trips Available to Purchase

Banda Aceh is one of many cities in Indonesia that has experienced an increase in the ownership of private vehicles. Private cars and motorcycles participate in both mandatory and non-mandatory activities. The increasing number of private vehicle owners can have an impact on the transportation system. Currently, Banda Aceh Local Government is operating Bus transit system: The Trans Koetaradja Bus which is expected to reduce congestion and the use of private vehicles in the city. The purpose of this study is to analyze the effect of individual motivation variables (latently) on mode choice (private vehicle or Trans Koetaradja bus), considering the types of transport-generating activities (mandatory and non-mandatory). The multivariate approach of Confirmatory Factor Analysis (CFA) is used to explore and determine the contributing motivation factors on their selection of daily mode choice. The empirical findings from this study have explicitly investigated the relationship between motivation factors and their attributes/indicators. The first results of the measurement model show that mandatory trips have the highest significant correlation with the attribute of preference to the use of private vehicles, meanwhile, the non-mandatory trips have the most significant correlation to the increasing level of congestion within the city due to high dependency on private vehicle. The second model is the relationship amongst motivation variables. The results show that as for mandatory activities appear that linkage with private vehicles significantly affects private vehicle problems, while in non-mandatory trips the quality of service of the current bus system has significantly affected satisfaction on using public transport.
