Maybe there has been some research done, and some is being done, but more research cannot hurt. Most of the research seems to be data collection on statistics with no underlying analysis of why these things are happening, and no in my view no deep research into how lorries can be made safer.
i think you need to go do some more searching - there's a reasonable amount of research already (that is not just secondary data - read, statistical - analysis)
