Thammasat University focuses developing safe and sustainable campuses to promote work-life balance among the Thammasat community as well as to allow the public an access to green spaces close to nature. The University has issued a policy on safety management, developed sustainable transportation system in the University, and provided safe and accessible public spaces.

Thammasat University has created road and transportation system that can accommodate all modes of transportations: walking, bicycles, motorcycles, service shuttles and private cars. The University ensures that the students and staff can choose the mode of transportation that suits their situations without fearing for their own safety. Designated covered walkways, crosswalks, and bike lanes are created all around the campuses to reduce the chance of road accidents and encourage the reduction of car use. A system of service shuttles runs around through all the main places on campus. Some portion of the service shuttles on campus has been converted to electric vehicles. This change is an attempt of the University in reducing the environmental impact.

Thammasat University Rangsit Campus focuses on balancing the use of space on campus. About half of the Rangsit Campus is still green space which can be used for recreation and exercise purposes and allows the students, staff, and the public to live a balanced life in nature. Among the developed space, the University focuses on providing spaces for sports and recreational activities to encourage everyone in the Thammasat Community to achieve balance between working/studying and personal life.
