Popis: | Determination of the impact of Traffic Safety Programs (TSPs) on motor vehicle crash rates forces the evaluator to utilize N of 1 quasi-experimental designs. A variety of procedures which take into account the serial dependency frequently observed in such data is described, and their application to assessment of change in crash time series is illustrated. |
