Fuel consumption is directly related to the vehicle velocity curve of arterial road, which includes many acceleration/deceleration patterns and idling times affected by traffic signals. With the development of modern wireless communication technology, the vehicle can get real-time information of the traffic signal information ahead. This paper creates an arterial velocity planning algorithm, which includes optimization calculation of the velocity curve part, calculation of acceleration-cruise-stop part and cruise-stop part, to suit the different conditions of the traffic signal phase and timing information. This algorithm sets running time and the acceleration as the optimization targets to ensure that the vehicle will avoid the sharp acceleration/decelerations and pass through intersections without coming to a stop. Thereby, the fuel consumption of vehicle with arterial velocity planning algorithm could be reduced by more than 14 %.
