Transportation Systems Planning/Traffic Information Laboratory (Professor : Keechoo Choi)
TPTI Lab., leading transportation research, established in 1994 by Prof. Keechoo Choi, focused on research for transportation system planning, ITS based on traffic information, and TOD (Transit-oriented development). Detailed research topics are as follows.
I. Transportation systems Planning
- theoretical research on travel demand and transportation network development based on optimization
- establishment and assessment of short- and long-term transportation planning methods via transportation systems analysis and statistical methods
- GIS-T based methodology development for macroscopic planning and travel demand forecasting
- emission integration into transportation planning
- traffic safety planning
II. Traffic information & ITS
- statistical analysis for creating traffic information
- data fusion methods of for reliability and accurate traffic information
- simulation analysis with traffic information and travel behavior
- highway sign systems development; highway signage improvement with new technology and lighting
III. TOD (Transit-Oriented Development)
- green transportation systems integration
- integrated green transportation systems with TDM
- TOD-based travel behavior and land use development
The Advanced Transportation Lab carries out research on various core technologies needed for developing efficient transportation systems. Especially our lab focuses on the research fields including traffic signal control and operation, traffic simulation, freeway management systems, and ITS. Our lab also has conducted many research projects funded from various sectors including National Research Foundation (NRF), National Police Agency (NPA), government, and private companies.
Systems Analysis and Assessment Laboratory (Professor : Jeongwhon Yu)
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.
