乘客:候车乘客通过电子站牌,可方便获取本班车次和下趟班次的到站时间,可时刻掌握车辆的行车轨迹并同时根据车厢拥挤情况自由选择乘坐班次;车内乘客则可通过车内的电子屏屏幕,实时掌握行进线路的路况信息。

司机:驾驶员可通过车内OBU或VBOX,与路侧RSU互联互通,实时掌控前方道路的路况信息。如遇信号灯盲区、交通事故拥堵时,驾驶员可同步收到信号灯实时状态信息及事故提醒建议和绕行通知等,与此同时,驾驶员还可将延误原因实时回传至调度指挥大厅及其他班次车辆,其他临近班次可通过信息提示提前作出预警判断,从而实现驾驶安全、提高交通通行效率。

调度指挥:指挥大厅可从后台显示屏掌控各趟班次的实时行驶状态,如遇车辆因故跟车较近或较远时,系统可自行向驾驶员发出车速引导提醒,保持每趟班次的到站时间和间隔时长相对固定;

信息安全:驾驶员接收信息的屏幕或语音、车内乘客信息来源屏、汽车尾屏等显示设备,在通信信息传播过程中的所有输出信息均有底层安全防护——即使有非法或不合规信息试图“劫持”信息输出,路侧的RSU及车辆装置OBU可通过安全机制设置,自动屏蔽此类信息,以确保信息传输的真实性、稳定性。
