We construct a driving environment reconstruction and analysis system based on multi-sensors network onboard and some functional subsystem as well. With the data acquired, processed and stored, the real comprehensive driving environment, which includes vehicle dynamic state information, traffic environment information and driving behavior information, can be established accurately and provide what had happened in and around the vehicle. Besides, this system can also provide the researchers with additional and important information, for example traffic sign, moving object and driver gaze information. Practical results show this system is a very powerful technical framework to deep incident analysis and a quantitative evaluation measure to the effect of passive and active safety technologies, which can promote and formulate vehicle safety measures or reduce serious injuries and disabilities in addition to the reduction of fatalities and injuries in general.
