The invention discloses a method and device for determining the vehicle driving direction based on the number of ETC portals. The method comprises the following steps: acquiring the number of ETC portals passed by the target vehicle sensed by an antenna of a current ETC portal from a local area network formed by the ETC portals; determining the number of the ETC ports at the upstream of the current ETC portal from the ETC portals through which the target vehicle passes: if the number of the ETC portals at the upstream of the current ETC portal is greater than the product of a preset value andthe number of the ETC portals through which the target vehicle passes, determining that the target vehicle is a vehicle running in the lane where the current ETC portal is located. On the one hand, the coupling degree of each ETC portal is low, the risk resistance is high, the uncertainty of determining the driving direction of the vehicle is reduced, and the reliability is improved; on the otherhand, the process of judging the product of the number of the ETC portals at the upstream of the current ETC portal and the number of the ETC portals passed by the target vehicle is quick and efficient.

    本发明公开了一种基于ETC门架数量确定车辆行驶方向的方法及设备,该方法包括:从ETC门架组成的局域网中,获取当前ETC门架的天线感应到的目标车辆途经的ETC门架的数量,确定目标车辆途经的ETC门架中,当前ETC门架上游的ETC门架的数量,若当前ETC门架上游的ETC门架的数量大于预设值与目标车辆途经的ETC门架的数量的乘积,则确定目标车辆为行驶于当前ETC门架所在车道中的车辆。一方面,各个ETC门架的耦合度低,风险抵抗性强,降低了确定车辆行驶方向时的不确定性以及提高了可靠性;另一方面,上述判断当前ETC门架上游的ETC门架的数量与预设值与目标车辆途经的ETC门架的数量的乘积大小的过程快捷高效。
