Abstract

Background/Context: Common perceptions of elevated collision risk during holiday periods normally trigger the allocation of enhanced traffic safety enforcement and publicity campaign resources around holidays in most jurisdictions. In Canada, for example, safety campaigns, and enhanced enforcements are normally planned around major holidays, such as Victoria Day, Thanksgiving and Christmas (VTC). There is scanty of research conducted to investigate whether the enhanced safety initiatives around the major holidays significantly contribute to increased public safety.

Aims/Objectives: This paper aimed to contribute to the debate on efficient allocation of traffic safety resources by investigating: 1) the aggregated effects of statutory holidays on casualty collisions and casualties, 2) the relative risk of alcohol involvement in holiday casualty collisions and casualties, and 3) the safety benefits of enhanced enforcement during VTC holidays.

Methods/Target Group: Motor vehicle collisions, along with their characteristics during Saskatchewan’s major holidays, as well as non-holidays, were extracted from SGI’s Traffic Accident Information System (TAIS) for a period of six years (2008-2013). This study used the negative binomial regression method to compare the risk of casualty collisions and casualties between: a) holiday and non-holiday periods and b) targeted holidays with enhanced enforcement (i.e., VTC) and other less-targeted holidays. The likelihood of alcohol involvement in casualty collisions during less-targeted holidays was compared to that during VTC by using logistic regression method.

Results/Activities: The results indicate that holiday periods were associated with 15% higher risk of casualty collisions and 82% higher risk of casualties (deaths and major injuries) relative to non-holiday periods. It is also evident that the risk of alcohol involvement in casualty collisions and casualties during major holidays was increased by 60% and 155%, respectively. Further investigation of specific holiday periods revealed that the risk of casualty collisions during VTC did not significantly differ from most of the less-targeted holiday periods, except for Remembrance Day and Easter holidays. Remembrance Day was associated with 31% higher casualty collisions than the VTC. In addition, Easter, Remembrance Day, Family Day, and New Year holidays had higher overall alcohol related casualty collisions than VTC.

Discussion/Deliverables: Safety promotional programs through radio/television advertisement and poster messages are recommended on an on-going basis around holiday periods. Promotional messages against drinking and driving and enhanced enforcements are highly recommended during less-targeted holiday periods, especially Easter, Remembrance Day, Family Day, and New Year’s Day holidays to improve public safety.

Conclusions: The study outcome supports the common perception of elevated collision risk during all holiday periods and warrants additional efforts to improving and promoting traffic safety around statutory holidays.
