My condolences to the family. I hope this can learn to valuable learning from this loss of life. Really interested in what data analysis is done in the states regarding (KSI - Killed and Serious Injured). In the UK we hold good data and can related designs and design improvement to the KSI. I strongly agree with the article, we should aim for zero-killed. The balance can be vehicle congestion vs. space vs. cost vs. time. Because our modelling is very good we can tell the impact of a new school and the behaviour of the pedestrians. I could talk about the hierarchy of roads, but Traffic Engineers need to start influencing the politicians that make some of the decisions. How ? - By clear data and model that show with this design you will have this KSIs.
