  • Vulnerabilities of the case-crossover method as applied to transportation injuries and traffic engineering problems
    M Kary

    The case-crossover method in its familiar application is to look for factors that recur when cases occur, for individuals crossing exposure to them as examined over a time interval. This study [1-3] applies the method in a different way, the exposures being examined over a spatial route, with neither the identified factors nor the various routes being independent of the highly constrained urban geographies of the se...

  • COMPARING DEATHS DUE TO POLITICAL VIOLENCE AND ROAD CRASHES IN NOTHERN IRELAND
    Tony H. Reinhardt-Rutland

    Sosa and Bhatti (1) show that death rates arising from political violence exceed death rates from road crashes in some localities of Afghanistan. In contrast, data from OECD countries indicate that the former are far less common than the latter (2). An implication is that Afghanistan is justified in devoting heavy resources to terrorism. In contrast, OECD countries should be more relaxed regarding the terrorist threat a...

  • Potential value of East York dataset
    M Kary
    I would like to add to the Editor's argument [1] by emphasising the uniqueness, and the potential value, of the East York ridership dataset.

    Over the past 23 years, laws prohibiting children (or everyone) from riding bicycles, unless they wear helmets, hav...

  • AUDITORY CONTRIBUTIONS TO ROAD-SAFETY: IMPLICATIONS FROM AFTEREFFECTS OF AUDITORY MOTION AND VISUAL MOTION
    Tony H. Reinhardt-Rutland

    Schwebel (1) raises the issue of how auditory processing might contribute to safe negotiation of the roads by pedestrians. In particular, does the masking of relevant auditory information entail unnecessary danger? Almost coincidentally, a recent review (2) has considered possible technological developments that might provide useful supplementary information to aid drivers in avoiding collisions: potential sources might be...

  • Furthering the interests of every apple: The need for reliable injury data collection in Queensland.
    Melissa Kaltner
    Re: Comparing apples with apples? Abusive Head Trauma, Drowning and LSVROs (response to Kaltner, Kenardy, Le Brocque & Page, 2012), by Watt, Franklin, Wallis, Griffin, Leggat and Kimble (2012)

    Developing the epidemiological literature base on the occurrence of all forms of childhood injury is essential to the development and promotion of injury prevention efforts. As is rightfully highlighted by Watt, Franklin, Wall...

  • IMPEDIMENTS TO THE PREVENTION OF TRAVEL-RELATED INJURY: SOCIETAL AS WELL AS INDIVIDUALISTIC
    Tony H. Reinhardt-Rutland

    Hemenway (1) describes three beliefs which may jeopardize injury- avoidance: optimistic ("it will never happen to me"), fatalistic ("accidents happen") and materialistic ("you probably deserved it"). Such a scheme parallels well-known trait theories regarding the individual's general personality (2); given the value of those endeavours,Hemenway's scheme deserves serious consideration.

    Nonetheless, it may be inco...

  • Old hypothesis that roads are safer than cycle tracks unsupported by data
    Anne C. Lusk

    We acknowledge that we did not control for all of the differences in road geometry and building typologies because there are no ideal matched streets (Re: Cooper). However, alternative research designs also have limitation and feasibility issues. For before and after study designs, some of the Montreal cycle tracks are 20 years old, before injury surveillance and traffic counting data systems were available. Limiting to...

  • Effectiveness of breed-specific legislation in decreasing dog-bite injury hospitalizations in Manitoba--what it means to researchers, policy-makers and the public
    Malathi Raghavan

    Our population-based study (1) on the effectiveness of breed-specific legislation (BSL) targeting pit-bull (terrier) type dogs in the Canadian province of Manitoba generated some interest in the media and among policy -makers and the public in Canada and the United States (2-10). With this experience of listening to different stakeholders and communicating with some, we hope to elaborate on our findings in language that is...
