Developing countries are suffering from serious transportation problems in recent years due to inefficient transportation systems and intense vehicle usage on limited highway network. Among these transport problems traffic congestion and air pollution are heavily deteriorating the quality of urban environment. Therefore, socially and environmentally viable policies are required for such countries. This study proposes a two-leveled Nested Logit (NL) model for two-traveler households where upper level consists of car-owning/motorcycle-owning/no vehicle-owning choices and lower level represents mode choices (fig. 1). The car and motorcycle trip chains are included as mode choice options in the NL model. The estimated NL model is successfully applied to investigate the impact of redistributing work and house locations. It is found that the reduction of travel distances with this policy will solve traffic congestion and environmental pollution in the region considerably. Proposed model and the policies are verified using Bangkok Metropolitan Region (BMR) as a case study.
