安全一直以来都被视为交通的首要任务,道路交通安全的一些技术国内国外都在试验性地运作,并得到广泛推广。近日,记者在北京举行的一次专题研讨会上聆听了北京工业大学交通研究中心陈艳艳教授的演讲,对事故风险的起因、规避以及感知技术等有了新的认识。 Safety has long been regarded as the primary task of transportation. Some of the technologies for road traffic safety are experimentally operated at home and abroad and widely promoted. Recently, the reporter listened to a speech delivered by Professor Chen Yanyan at the Traffic Research Center of Beijing University of Technology at a special symposium held in Beijing, giving new insights into the causes, avoidance and perception technologies of accident risks.
