In Canada, the Department of Civil Engineering at the University of Calgary has undertaken a two-year research project to determine how motor homes, truck campers, pickup truck campers, camper trailers and collapsible trailers are changing the highway environment. They have reviewed the methods and criteria which highway agencies have used to determine adjustment factors for trucks and buses incorporating passenger car equivalents. By field investigation on routes of different character and classification they observed and measured the effect of recreastional vehicles on highway capacity. If the recreational vehicles were not considered, highway capacity and service volumes would tend to be considerably overestimated. If they were considered as trucks or buses, there would be a tendency to underestimate the service volumes for rolling and mountainous terrain. For level terrain it made little difference to which type of vehicle they were compared. According to the manner in which the recreational vehicle was handled in the highway capacity computation, highways may have been considered for improvement too late or too early in their lives.
