^The good thing about systemmatic accident investigations is they generate not just the immediate causes of the event, but they also look at the latent things that may either interact with, or aggravate, the damage.
An example here is the design of the shelters. I bet that nobody considered that the overhanging roof overhang was a perfect “can opener” at just the right height to slice open a DD bus and inflict damage on the upper level. Bus shelters are designed to look pretty and hold people, but are they analysed for how they will work if struck by a bus? Interestingly, there are crash standards for new buildings within x meters of a railway track, as there is always the possibility of a derailment. That same analysis probably hasn’t happened to set standards for busway design.
It’s too soon to know why this bus left the roadway, but I bet there will be recommendations about how to separate buses from pedestrians at stops, and whether there should be fixed barriers around structures. Get ready for some jersey barriers.
