  • Critique of: "Risk of Injury for Bicycling on Cycle Tracks Versus in the Street"
    Wayne E Pein

    The investigators did not meaningfully compare Relative Bicycling Risk and Relative Traffic Danger for individual pairs. Such a comparison of their data demonstrates that the Apparent Cycle Track Effect was increased Danger to bicyclists at two cycle tracks, Neutrality at two cycle tracks, and increased Safety at two cycle tracks. This contrasts with the investigators' claim that the six cycle tracks had a combined 28% l...

  • THE EFFECTIVENESS OF DEDICATED CYCLING FACILITIES: PERCEIVED AND OBJECTIVE RISK
    Tony H. Reinhardt-Rutland

    Lusk et al's paper (1) indicates an important subtext regarding travel. Governments wish to make personal mobility as widely available as possible; this inevitably entails promotion of the private automobile, which can provide convenient and comfortable travel for the widest range of individuals, including those for whom disability would otherwise pose severe limitations in participating in society. However, there is a...

  • Re:Re:Zero Blood Alcohol Concentration (BAC) Limit for drivers under 21
    Robert M> Solomon

    The major problem in enforcing the zero BAC limit is ensuring that the province or territory enacts accompanying legislation authorizing the police to demand a breath sample from drivers subject to this limit. There has been no problem with drivers testing positive with exceedingly small amounts of alcohol in their breath samples, because of natural processes or diet. Presumably, the machines have thresholds to eliminate...

  • Re:Zero Blood Alcohol Concentration (BAC) Limit for drivers under 21
    Solitay Taiwo

    How easy is it to enforce zero limit in the face of possiblity of physicigical sources of alcohol and uses of other dietry and household sources of alcohol? There might be a lot or few false positive cases as a result. Is there anything of in the scientific evidence base?

  • Cycle helmet law not properly assessed
    Colin F Clarke

    Reading the article, The effects of provincial bicycle helmet legislation on helmet use and bicycle ridership in Canada (ref 1), it appears the conclusions reached were ill considered and unreliable for a number of reasons.

    The article concludes that helmet legislation is not associated with changes in ridership. This statement is somewhat misleading. Fig 3 in the article shows trends of recreational bicycle u...

  • Belt up...Speed up?
    Tony H. Reinhardt-Rutland

    The story of seatbelts has ever been one of success - at least for government bodies and the motor industry. However, seatbelts have an unfortunate side effect owing to the dissipation of the kinetic and vestibular discomfort associated with acceleration and deceleration: in effect, faster and more erratic driving is encouraged.

    Moreover, any savings in casualties among motor vehicle occupants must be weighed...

  • Interpreting the statistics: underestimation of casualties and vulnerable road-users
    Tony H. Reinhardt-Rutland

    Dear Editor

    Jeffrey et al's [1] evidence of a serious underestimation of road injuries is worrying for the year-by-year comparisons that are taken as evidence for the state of road safety. The UK figures for death and serious injury are reported to have followed a downward trend for forty years or so, which has generally been taken as evidence - if no more than implicitly - that a culture of safety on the roads i...

  • Preventing Road Traffic Injuries in Africa.
    Adam L Kushner

    As noted in the recently released WHO and UNICEF World Report on Child Injury Prevention, globally, road traffic injuries (RTI) are the leading cause of death among 10-19 year-olds with more than 260,000 children dying from RTIs each year. (1) In addition, an estimated 10 million more children are non-fatally injured. Africa has the world's highest RTI mortality rate at 28.3 per 100,000 (2), yet relatively few resources...

  • lit search analysis method
    David L Nordstrom

    Several analyses of the results of bibliographic databases have shown that--for several health fields and subjects--the number of databases searched influences the number of papers found. Library and information scientists seem to use certain methods and outcomes in their analyses. I am curious whether this study used the same methods and measures.

  • Simple Ways for Saving Lives
    Rizaldy Pinzon

    The article of Dr. Stevenson's is very interesting. This article showed that intervention increasing the use of safe belt. Traumatic brain injury is one of the most leading causes of death and disability in developing countries. In Indonesia, there are numerous reports that showed high mortality is correlated with unsafe practice of driving or motorcycling. Previous report showed that the use of safety belts is the single...
