Many traffic deaths and injuries are related to speeding. Thus, establishing speed limits and enforcing them are fundamental measures for promoting safe traffic. It is known that automatic speed enforcement, in particular, the average speed enforcement, effectively counters excessive speeds. In Brazil, only on site inspection of speed is regulated. Thus, testing the effectiveness of other countermeasures in reducing the average vehicle speed is indispensable. This study aimed to analyze the effects of a traffic education campaign (exposure of drivers to damaged vehicles on public roads) on the average speed behavior of drivers on urban roads who usually travel above the allowed speed. The average speeds of the (paired) vehicles before and after the introduction of the educational campaign in three segments were compared. The obatined results showed that the traffic campaign was effective in reducing the average vehicle speed by drivers who usually traveled above the allowed speed in the analyzed segments. The magnitude of the campaign effect (average speed reduction) was observed to be greater during its execution and lost strength when interrupted, especially on the sixth and seventh days after completion, corroborating that the traffic campaign measures (although low cost and easy to execute) had limited effects on the time and place of their realization. The results of this study can be used in the future as an indicator that people actually do worry about the consequences of speeding, as is the case with the vision of damaged cars.

交通活动对城市道路上车辆平均速度的影响


许多交通伤亡与超速有关。因此，制定限速并执行限速是促进安全交通的基本措施。众所周知，自动超速执法，尤其是平均超速执法，可以有效地对抗超速。在巴西，仅对速度进行现场检查进行监管。因此，测试其他对策在降低平均车速方面的有效性是必不可少的。本研究旨在分析交通教育活动（驾驶员在公共道路上接触受损车辆）对城市道路上通常以超过允许速度行驶的驾驶员的平均速度行为的影响。比较了三个细分市场中引入教育活动前后的（配对）车辆的平均速度。观察结果表明，交通活动有效地降低了通常超过所分析路段允许速度的驾驶员的平均车速。观察到活动效果的大小（平均速度降低）在执行过程中更大，而在中断时失去强度，尤其是在完成后的第 6 天和第 7 天，证实了流量活动措施（虽然成本低且易于执行）对其实现的时间和地点的影响有限。这项研究的结果可以在未来用作一个指标，表明人们确实担心超速的后果，就像看到损坏的汽车一样。
