为城市路口道路交通“做规矩”的人

Core Viewpoint - The article highlights the significant contributions of Yang Peikun, a pioneer in China's traffic engineering discipline, emphasizing his role in advancing urban traffic management and signal control systems through practical experience and innovative research. Group 1: Early Life and Education - Yang Peikun was born in February 1932 and graduated from Tongji University in 1953, where he began his academic career [12] - He initially studied civil engineering at Fudan University, later transferring to Shanghai Jiao Tong University, and finally completing his education at Tongji University, where he specialized in road and traffic engineering [15][17] Group 2: Academic Contributions - Yang Peikun was instrumental in establishing the first urban construction department in China at Tongji University in 1956, marking a significant shift in academic focus towards urban traffic studies [18] - He developed the first national textbook on urban road traffic in 1961, which laid the foundation for systematic traffic engineering education in China [13][24] Group 3: Practical Experience and Research - Yang's unique approach involved practical observation as a traffic police officer to resolve theoretical ambiguities in traffic signal control, leading to the development of the "conflict point method" for calculating intersection capacity [20][22] - His research methodology emphasized the importance of grounding theory in practical experience, which became a cornerstone of his academic work [22] Group 4: Establishing Traffic Engineering as a Discipline - In 1978, Yang Peikun established the Traffic Engineering Research Room at Tongji University, the first of its kind in mainland China, which facilitated the development of advanced traffic engineering studies [23][24] - He played a crucial role in creating the first master's, doctoral, and postdoctoral programs in traffic engineering in China, further solidifying the discipline's academic framework [24][25] Group 5: Innovations in Traffic Management - Yang introduced the concept of "new-style intersections" after studying traffic management in the United States, which improved traffic flow efficiency in Chinese cities [27][28] - He authored the national standard for urban road intersection planning, which was published in 2011 and emphasized human-centered design principles [28] Group 6: Advancements in Intelligent Traffic Systems - Yang Peikun led the development of China's first adaptive traffic signal control system, marking a significant shift from reliance on imported technology to domestic innovation [29][30] - His contributions to intelligent transportation systems (ITS) laid the groundwork for future advancements in traffic management and control in China [30] Group 7: Ongoing Influence and Legacy - Even after retirement, Yang continues to contribute to traffic engineering discussions and research, demonstrating his enduring commitment to improving urban traffic systems [31][32] - His life’s work reflects a profound impact on the evolution of traffic engineering in China, transitioning the field from its nascent stages to a robust academic and practical discipline [32]
