面向交通安全研究的实验设计及方案评价

针对交通安全实验日益复杂,实验成本日益增加,科学、有效的实验结论的获得日益困难的现状,在给出交通安全实验概念及特点的基础上,从定性和定量两个方面,以偏差和实验次数作为定量指标,以可控性、可重复性、鲁棒性和可拓展性为定性指标,以采用最经济的实验方案、获得最优实验效果为原则,建立了交通安全实验方案评价体系.提出了交通安全实验设计流程。实际应用证明:本文提出的交通安全实验设计流程和实验方案评价体系清晰合理、科学可靠、切实可行,为我国交通安全实验提供了一种切实可行的研究途径,对于提高我国交通安全研究水平具有一定指导意义。

Design and Evaluation of Experiments for Traffic Safety Research

In order to solving such problems as the more complex and costly of traffic safety research experiment,the concept and char- acteristics of experiments for traffic safety research is given.The experiment scheme evaluation system is provided according to many qual- itative indexes such as controllability,repeatabihty,robustness,extendibility of the experiment scheme and quantitative indexes such as the deviation of experiment scheme and the experiment times.The principle of the proposed experiment scheme system for the best experi- ment results is put forward according to the most economical experiment scheme.Based on the mentioned experiment scheme evaluation system,the procedure of design of experiments for traffic safety research is proposed.It provides a realizable way for research on the ex- periments of traffic safety research,and has certain instructing significance for improving of our traffic safety research.
