  • False assumption that all new cyclists previously drove
    Mark Kaepplein

    Your air pollution reduction benefit is based on a very poor assumption of all new cyclists were former drivers (per Rabl and De Nazelle) could be no more wrong than in NYC with the biggest public transit system in the US, lowest per capita car ownership and miles driven of any major city, and where over 56% of workers use public transit, and over 10% walk.

  • A Comment on May et al. (2002)
    Gary D. Kleck

    A survey of jail inmates done by J P May, D Hemenway, and A Hall indicated that, among those who admitted to having been shot, 91% reported having gone to the hospital for treatment. This comment explains why this finding cannot be taken seriously.

    Put yourself in the position of a jail inmate who was part of this survey. Most jail inmates are awaiting trial. They are the most legally vulnerable of all crimina...

  • 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...
