The INFORMS Transportation Science and Logistics (TSL) Society was formed in 2004 with the merger of the Transportation Science and Logistics Sections. The Aviation Applications Section affiliated with the Society in 2008.

The TSL Society provides INFORMS members with a sustained, specialized focus on these topics, including current and potential problems and contributions to their solution, and supports efforts to extend, unify, and integrate related branches of knowledge and practice. We encourage the education of students and the continuing education of practitioners. The Society is the editorial home of one of INFORMS’ flagship journals, Transportation Science. The Society includes, in addition to the Aviations Applications Section, four special interest groups: Freight Transportation and Logistics, Urban Transportation Planning and Modeling, Facility Logistics, and Intelligent Transportation Systems. Collectively, the Aviation Applications Section and the Transportation Science and Logistics Society include just under 1,000 members, almost half of whom are students. More are welcome.
