The Ph.D. in Traffic Engineering is a research-oriented doctoral program designed to cultivate advanced scholars and professionals in the study, design, operation, and management of traffic systems. Typically offered under the discipline of Transportation Engineering or Traffic 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 guidance and supervision may also be available in English for international students.

The program aims to develop experts with deep theoretical knowledge, advanced analytical skills, and strong research capabilities in traffic flow theory, traffic control systems, traffic safety, and intelligent transportation systems (ITS). Graduates are trained to design, optimize, and manage complex urban and regional traffic networks, improve operational efficiency, enhance safety, and integrate new technologies such as automation, data analytics, and connected vehicles into traffic engineering solutions.

NOTE: The university may have additional program-specific eligibility requirements.
