Time-speed data points

The New York Composite (NYComp) cycle is a chassis dynamometer test for heavy-duty vehicles representative of actual driving patterns in New York City. The test—also known as the New York Bus Composite (NYBC) cycle—is a compressed version of the US EPA “unfliltered bus test cycle”.

Vehicle speed over the duration of the NYComp test is shown in Figure 1.
