The invention belongs to the technical field of vehicle passing control, and particularly relates to a V2X-based priority passing method and system, and the method comprises the steps: enabling the information of a vehicle with priority passing authority and encryption and decryption public and private key pairs to be pre-stored in a cloud server in V2X, and presetting a one-way road sign containing a digital watermark on a one-way road; a target vehicle collects a one-way street sign image, obtains a street end point position by extracting and verifying a digital watermark, obtains a distance from the target vehicle to the target vehicle by using the one-way street end point position, and sends a priority passing request to the cloud server when the distance meets a preset threshold value; the cloud server verifies the passing authority of the target vehicle by using pre-stored vehicle information and feeds back a verification result to the target vehicle and the roadside end; and the roadside end generates priority passing indication information, so that the target vehicle reversely and preferentially passes on the one-way road. According to the invention, the digital watermarking is combined with the V2X vehicle networking technology, so that the target vehicle of the specific task can utilize the one-way road to preferentially reverse.
本发明属于车辆通行控制技术领域,特别涉及一种基于V2X的优先通行方法及系统,首先将享有优先通行权限的车辆信息及加解密公私钥对预先存储在V2X中的云端服务器,在单行道上预先设置含有数字水印的单行道标牌;目标车辆采集单行道标牌图像,通过提取并验证数字水印来获取行道终点位置,利用单行道终点位置来获取与自身之间的距离,当该距离满足预设阈值时,向云端服务器发出优先通行请求,云端服务器利用预先存储的车辆信息验证目标车辆的通行权限并将验证结果反馈至目标车辆和路侧端;路侧端生成优先通行指示信息,使目标车辆在单行道上逆向优先通行。本发明运用数字水印并结合V2X车联网技术来实现特定任务目标车辆能够利用单行道优先逆向。
