Excessive speeding is a major traffic safety concern consequently, numerous countermeasures have been considered to mitigate this problem. Excessive speeding, street racing and stunt driving activities subject all road users to extreme risk. To address this problem, three Canadian provinces introduced severe sanctions against drivers who exceed speed limits by high margins. Under the laws offenders were subject to immediate license suspension and vehicle impoundment. In this paper, intervention analysis of the collision data from the three provinces was conducted to identify the safety effects of the legislation. The analysis aims to identify changes in the time series behaviour of collision data after the adoption of the law. The changes were assessed for statistical significance, and the magnitude of the change was quantified. In general, the paper showed that the legislative changes were associated with drops in province-wide fatal collisions substantiating the safety benefits of introducing such legislation against excessive speeders.
超速行驶是主要的交通安全隐患，因此，人们考虑了许多对策来缓解这一问题。超速、街头飙车和特技驾驶活动使所有道路使用者都面临极高风险。为解决这一问题，加拿大三个省份对大幅超速的司机实施了严厉制裁。根据法律，违规者将被立即吊销驾照并扣押车辆。本文对这三个省份的碰撞数据进行了干预分析，以确定该立法的安全效果。该分析旨在确定法律实施后碰撞数据时间序列行为的变化。评估了这些变化的统计显著性，并对变化幅度进行了量化。总体而言，本文表明立法变化与全省致命碰撞事故的减少有关，证实了针对超速驾驶者出台此类立法的安全益处。
