Abstract

The speeding is a major road safety problem on the roads of Lithuania and many other countries. To reduce and control the speed of vehicles, engineering measures are installed on the roads of Lithuania and other countries – intelligent instantaneous and average speed enforcement systems, as well as many other engineering and structural speed reduction measures. The article presents good practices in the use of average speed enforcement systems, assessment of their effect on road safety. The article analyses the assessment results of the effect of the average speed enforcement systems installed on 25 sections of roads in Lithuania that have been operating for four years. Calculations of the effect factor of the installed average speed enforcement systems on road safety were performed using the before-and-after (B&A) method with a comparison group. Studies on the effect of application of speed control systems provide conditions for evaluating road safety, i.e., changes in road accidents linked to the effectiveness of implemented measures. The conclusions of the conducted study presented the calculations of the efficiency coefficients of the average speed enforcement systems on Lithuanian main and national roads. The analysis of the results of the conducted study allows stating that the installed average speed enforcement systems on 25 sections of Lithuanian roads increase overall road safety by 47%, reduce the number of collisions with animals by 80%, and the number of collisions with vehicles by 35%, as well as the number of other road accidents by 56%.

立陶宛道路平均速度执法系统的效果评估
超速是立陶宛和许多其他国家道路上的一个主要道路安全问题。为了降低和控制车辆的速度,在立陶宛和其他国家的道路上安装了工程措施-智能瞬时和平均速度执法系统,以及许多其他工程和结构减速措施。本文介绍了使用平均速度强制执行系统的良好做法,并评估了它们对道路安全的影响。本文分析了立陶宛25条道路上安装的平均速度强制执行系统的效果评估结果,这些系统已经运行了四年。采用前后对比(B&A)方法计算安装的平均速度强制系统对道路安全的影响系数。研究速度控制系统的应用效果为评估道路安全提供了条件,即道路事故的变化与实施措施的有效性有关。所进行的研究的结论提出了立陶宛主要道路和国家道路上平均速度强制执行系统效率系数的计算。对所进行的研究结果的分析表明,在立陶宛25条道路上安装的平均速度强制系统使总体道路安全提高了47%,与动物的碰撞次数减少了80%,与车辆的碰撞次数减少了35%,其他道路事故的数量减少了56%。
