Engineering for safety has been known since the industrial revolution brought heavy objects and assembly lines to the workplace and greatly increased the monetary benefit of avoiding accidents. Nobody wants to stop a whole line because someone got turned into a pancake. The answer is basically to segregate traffic by speed, tightly control the interactions between different speeds of traffic and to generally have lighter traffic yield to heavier traffic. This is pretty much standard in every industrial workplace worldwide at this point. Look at what's going on on the tarmac next time you go to the airport. Of course nobody wants to push for this in 2021 because it conflicts with a lot of the priors and ancillary goals that are floating around the ideological camp that most of the people who care strongly about traffic safety come from.
