面向零事故平交道口的车辆-铁路旁链通信

V2Rail 将铁路正向列车控制 (PTC) 系统与车载 C-V2X 收发器连接起来，在城乡平交道口前最远 2 公里处直接发出列车与车辆的碰撞预警。

杜绝列车与车辆同时占用同一交叉点

铁路平交道口是致命事故高发地带，重型货运列车往往需要数公里才能完全停下。V2Rail 会将机车速度、制动曲线以及预计到达道口的时间直接推送至驶近车辆的显示屏上。

Core Engineering Areas

Grade Crossing Collision Preemption Systems — 为驶近视线受阻平交道口的驾驶员提前发出声音与视觉警示。
Positive Train Control (PTC) Sidelink Bridge — 将重型铁路安全协议转化为标准化的车载协同感知消息 (CAM)。
Low-Latency Train Tracking Telemetry Over RF — 确保旁链路信号能够持续穿透铁路沿线的深岩堑与峡谷地带。
