The New York Bus (NYBus) Cycle is a chassis dynamometer test for heavy-duty vehicles, particularly for urban buses. The NYBus cycle is representative of actual observed driving patterns of transit buses in New York City. It is a short test cycle characterized by frequent stops, fast average acceleration, and low speed. The following are selected parameters of the NYBus test:
- Duration: 600 s
- Total driving distance: 0.99 km
- Maximum speed: 49.56 km/h (30.8 mph)
- Average speed: 5.94 km/h (3.7 mph)
- Average speed without stops: 17.11 km/h (10.6 mph)
- Maximum acceleration: 2.77 m/s2
- Average acceleration: 1.17 m/s2
- Number of stops per km: 11
Vehicle speed over the duration of the New York Bus cycle is shown in Figure 1.
