Table 2 shows a comparison of the energy usage of vehicles travelling in cruise
control with that of vehicles not travelling in cruise control for two different speeds. It
is assumed that in the cruise control scenario only the battery electric vehicles are in
cruise control mode. All other vehicles are travelling without cruise control.

Fig. 5. The figure shows energy consumption for two vehicle parameter sets, one with drivers
whose average desired speed is 60 MPH and the other averaging 50 MPH
