Our Mission

The transportation sector contributed to a large share of greenhouse gas emissions. In 2016, the transportation sector accounted for around 19.5% of Thailand’s national greenhouse gas emissions (United Nations Framework Convention on Climate Change, Third Biennial Update Report (BUR3)).

The 3DTraffic SATREPS Project in Bangkok studies on the greenhouse gas emission reduction measures in the ground transport sector. We believe that a smooth road traffic not only will improve travel efficiency, but also enhance the overall quality of the city’s environment.
