The Ph.D. in Traffic Information Engineering and Control is a research-oriented doctoral program designed to train advanced scholars and experts in traffic data acquisition, intelligent transportation systems (ITS), and traffic control technologies. Typically offered under the discipline of Transportation Engineering or Control Science and Engineering at leading universities such as Southwest Jiaotong University (SWJTU), this program is a full-time doctoral program lasting 3–5 years, with instruction primarily in Chinese, while research supervision and guidance may also be available in English for international students.

The program aims to cultivate professionals with deep theoretical knowledge, advanced analytical skills, and strong research capabilities in traffic flow modeling, traffic signal and network control, transportation data analysis, and intelligent traffic management systems. Graduates are trained to develop, implement, and optimize traffic information systems, enhance road safety and efficiency, and integrate emerging technologies such as big data, artificial intelligence, and vehicle-to-infrastructure communication into modern traffic control strategies.
