During the Spring Festival Travel Rush (SFTR) in China, many people travel and public vehicles are always full. This research studies the air pollutant exposure of commuters under five transportation modes: China railway high-speed train (CRH train), subway, bus, car, and walk. The routes are selected between Nanjing and Xuzhou. The volatile organic compounds (VOCs), carbon dioxide (CO 2 ), and formaldehyde (HCHO) levels are compared in five different transportation modes. The results indicate that personal exposure level to VOC and HCHO in CRH train is the lowest and relatively stable. So taking the CRH train during the SFTR may be the best choice. During the Corona Virus Disease 2019 (COVID-19) outbreak, spraying 70% alcohol for disinfection in public spaces significantly increased the personal exposure level to VOCs.
