Intervention analysis of the safety effects of a legislation targeting excessive speeding in Canada

  • Author(s) / Creator(s)
  • Excessive speeding is a safety concern on all Canadian roads, consequently, numerous countermeasures have been considered to mitigate this problem. Whether it is excessive speeding, street racing or stunt driving, these activities subject all road users to extreme risk. To address this problem, three Canadian provinces, namely, British Columbia, Ontario and Quebec, introduced severe sanctions against drivers who exceed speed limits by high margins. Among other sanctions, the legislation involved the immediate suspension of an offender’s license and the impoundment of his/her vehicle. In this paper, intervention analysis of the collision data, from the three provinces was conducted to identify the safety effects on the legislation. The main aim of the analysis was to identify any changes in the time series behavior of the collision data after the implementation of the intervention (legislation). The changes were assessed for statistical significance, and the magnitude of the change was quantified. In general, the findings showed that the legislative changes were associated with drops in province-wide fatal collisions substantiating the safety benefits of introducing such legislations to target excessive speeders.
