The Inter-Vehicle Communications (IVC) is one of the most important technologies to realize advanced Intelligent Transport Systems (ITS). We deal with Vehicle-PEdestrian Communications (VPEC) as the communications between vehicles and pedestrians. The objective of VPEC is to defend pedestrians from traffic accidents. In VPEC without any controls, pedestrians (p-nodes) transmit many packets to vehicles (v-nodes) to inform the positioning information of p-nodes. Since, the battery capacity of p-nodes is not sufficient to support these transmissions, it is necessary to suppress the transmissions of p-nodes to obtain proper information exchanges. In this paper, we present effective Reflect-transmission schemes which can reduce useless transmissions from p-nodes on VPEC. In addition, we present Silent Control Protocol, Mask Control Protocol and Distance-based Priority Control Protocol as more effective protocols for Reflect-transmission scheme. The proposal protocols can operate Reflect-transmission scheme more efficiently. Further, we carry out both computer simulation and experiments to verify the control behavior of VPEC. So we present the outline of experiments and show some results which we have obtained.
