4 Universities Joint International Conference (4UJIC)

Transportation-related researchers from four universities—the University of Calgary, the University of Seoul, Tongji University, and Kumamoto University—hold an annual joint conference. At the conference, researchers present their latest study results and exchange ideas on various transportation and urban-related research topics. The conference originated as a joint seminar between the University of Calgary and the University of Seoul, with Kumamoto University joining in 2010 and Tongji University following in 2014. Each university hosts the conference every four years. The 2026 conference in Calgary marked the 18th edition. Note that the conference is known by several names, including 4UJIC, 4UNIJC, 4Uni Conference, and 4UniC.
