Vulnerable Road Users
Historically, designers focussed on the rapid and efficient movement of motorised vehicles as transportation has always been defined as the safe, efficient, convenient and affordable movement of people and goods with minimum side effects. The last mentioned focussed on the environment and even that was biased by what was visible to the occupants of a moving vehicle. Obviously, pedestrians and others had no business being in the road reserve. Sidewalks were provided in urban areas but only as an afterthought.
