The City Suburban Cycle (CSC) is a chassis dynamometer test for heavy-duty vehicles developed by the West Virginia University. The CSC is also abbreviated as CSHVC (City Suburban Heavy Vehicle Cycle).
The test is also available in a “route” version—the City Suburban Heavy Vehicle Route (CSHVR)—where the vehicle speed is given as a function of travelled distance, rather than time.
Vehicle speed over the duration of the CSC driving cycle is shown in Figure 1.
