Inconsistencies between urban transport and land use are escalating in developing countries. Even though both transport and land use sectors have been gaining diverse improvements with economic growth, interrelation between them has not been well established at the stages of planning and decision making for those improvements. Due to this mismatch of transport and land use, vehicle ownership and usage in developing countries are rising rapidly causing urban areas for severe environmental damages, for instance traffic congestion and environmental pollution. This study attempts to investigate telecommuting as an interactive policy of transport and land use for developing countries. Firstly, a nested logit (NL) model is developed to investigate the household travel behaviour on vehicle ownership, mode choice and trip chaining aspects. The nest structure consists of two levels where the upper level characterizes with car owning, motorcycle owning and no vehicle owning choices, and the lower level represents the household related mode choices. Secondly, the estimated NL model is applied for policy analysis considering telecommuting. Several satellite offices are located outside the CBD to reduce commuting distances only for the travellers who can change their work places. The new locations for the satellite offices are decided considering travel convenience as well as its compatibility with the current road network. In addition, several policies are investigated by combining telecommuting with road pricing and transit fare reductions to understand the combined effect with the integrated policy aspects. The impacts of the policies are presented with the reductions of vehicle kilometres of travel and air pollution considering Bangkok Metropolitan Region as a case study.
