Transportation Engineering Laboratory (Professor : Ilsoo Yun)

Researchers in the Transportation Engineering Lab have systematically conducted research on diverse transport areas, including traffic control and operations, Intelligent Transport Systems (ITS) and safety, under the instruction of professor Yun, Ilsoo. Since 2009, the Transportation Engineering Lab has developed remarkable traffic signal control algorithms, ITS services, traffic stream control strategies, stochastic optimization methods, safety models, etc. In addition, many of those achievements have been published in many international and domestic journals. The performance of such developed algorithms and strategies have been evaluated via macroscopic traffic simulation models including SYNCHRO, microscopic traffic simulation models including VISSIM, and statistical & computer modeling using systematic and scientific approaches.
