In this study the effect of binoculair vision problems on taxi drivers' distribution of crashes is estimated. Moreover, given a crash, the effect of monoculair vision problems on the distributions of the number of victims per crash, is estimated. Data and models permit the simultaneous considerations of many variables: age, medical condition, exposure factors measured by distance driven and time behind the wheel, qualitative risk factors, other characteristics of the driver, and crash circumstances in the models for the number of victims. Results show that taxi drivers have a large average number of crashes per year, larger for those with binocular vision problems compared with healthy ones, but no more severe in terms of the number of victims. Age is associated significantly with the number and the severity of crashes with older drivers having a better record than the youngest group.
