The SIG C2 on Urban Transport Operations is a Special Interest Group of the World Conference on Transport Research Society (WCTRS).
SIG C2 was initially launched as SIG 15 on Urban Traffic Control at Nagoya University, Japan during its first meeting in November, 2011. Since its establishment, SIG 15 had been co-chaired by Hideki Nakamura (Nagoya University, Japan) and Manfred Boltze (Darmstadt University of Technology, Germany) until 2013.
According to the reformation of WCTRS-SIGs structure in 2014, the commitee was renamed as SIG C2, and expanded its topic area to "Urban Transport Operations". The chair was taken over by Zong Tian (University of Nevada, Reno, USA) with Hideki Nakamura as co-chair from January 2014.
The chair was taken over by Keshuang Tang (Tongji University, China) with Zong Tian (University of Nevada, Reno, USA) as co-chair from July, 2016 (the WCTR 2016).
Azusa Toriumi (the University of Tokyo, Japan) was elected as the second co-chair at the SIG meeting held during the WCTR 2019 in May, 2019. Keshuang Tang (Tongji University, China) and Zong Tian (University of Nevada, Reno, USA) remain to be the chair and the co-chair.
