Arthur Henderson, generally credited with coming up with the concept of kerb-guided busways back in the mid-60s, died on December 4th, aged 93. He was an engineer and for a time had a consultancy as well as leading something called the "Traffic Research Centre", which owned a small fleet of vintage buses, some of which were roadworthy and were occasionally seen on roads in the Cambridge area.
I have seen it suggested that he was involved in some way with the Adelaide guided busway (opened 1986).
I knew Arthur very slightly, in a non-transport context, but had no idea of his professional accomplishments.
