California: Heavy-duty: Orange County Bus


The Orange County Bus Cycle is a chassis dynamometer test for heavy-duty vehicles. It has been developed by the West Virginia University (WVU)[note]West Virginia University contact information[/note], based on the driving patterns of urban transit buses in the Los Angeles, California area. The OC Bus cycle should not be confused with the Orange County refuse hauler cycle, which also has been developed by the WVU.
