Large Truck Crash Causation Study (LTCCS)

The Large Truck* Crash Causation Study (LTCCS) is based on a three-year data collection project conducted by the Federal Motor Carrier Safety Administration (FMCSA) and the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation (DOT). LTCCS is the first-ever national study to attempt to determine the critical events and associated factors that contribute to serious large truck crashes allowing DOT and others to implement effective countermeasures to reduce the occurrence and severity of these crashes.

大型货车碰撞成因研究（Large Truck* Crash Causation Study，LTCCS）基于美国运输部（U.S. Department of Transportation, DOT）下属的联邦机动车安全管理局（Federal Motor Carrier Safety Administration, FMCSA）与国家公路交通安全管理局（National Highway Traffic Safety Administration, NHTSA）开展的为期三年的数据采集项目。本研究是全美首个旨在明确严重大型货车碰撞事故关键致因事件及相关影响因素的全国性研究，可为美国运输部及其他相关机构推行有效应对举措，降低此类碰撞事故的发生概率与严重程度提供科学依据。
