　　【Abstract】In the past two decades, with the increasingly weak response of normative law to traffic reality problems, traffic law has experienced a paradigm change from the closed-loop of dogmatics of law to the cross research of le-gal sociology. The management theory leads to the upgrading and transformation of traffic governance mode, while social collaborative governance and “big traffic” law enforcement mode emerge as required. Information technolo-gy, medicine, microelectronics, environmental science, and other natural science research methods developed from the legislative demand of the oriented fragmentation to the legal research methodology level in full. Psychology, comparative law, and feminist law provide abundant theoretical support for the vigorous development of traffic law. The interdisciplinary research advantages of traffic law are fully demonstrated. Traffic law has changed from the standard-oriented “department law” to a problem-oriented “comprehensive law”, breaking through the barriers of the legal discipline system, and moving towards a multi-disciplinary research approach. With the rapid development of transportation technology, the demand for the protection of human dignity calls for the return of legal philosophy research methods.
