首条车联网道路落地亦庄

2017-08-14 03:17:50   中国青年网

本报记者 赵鹏

最近驱车驶过大兴亦庄荣华中路与景园街的市民发现,几块“智能车联开放道路”的蓝色交通指示牌悬挂在了道路两侧,这就是本市首条车联网专用车道。对于联网的测试车辆,盲区提醒、紧急车辆接近、行人闯入、绿灯通过速度提示、优先级车辆让行等10多种预警和提醒将让驾驶变得更安全。

记者获悉,后续本市会在通州和房山继续扩大车联网专用车道试点。技术牵头方北京千方科技股份有限公司方面透露,车联网技术一两年内有望率先在北京的出租车、公交车等营运车辆中推广。

车联网扫清驾驶盲区

“老司机都知道,就算你不撞别人,也很难避开别人撞你的事故,因为视野有限。车联网就是要帮你扫清驾驶盲区。”千方科技行业研发中心项目经理孙松源介绍。

昨日,他带记者体验了一把车联网。测试车辆是一辆白色轿车,与普通家用车没有明显差别,但仔细留意会发现,车顶额外加了两条天线,车内配备了车载智能终端和显示屏。驱车右转经过荣华中路与中和街十字路口的时候,路口一块大型显示屏打出了这样的提示:“左方来车注意安全”。果然,车刚完成右转,一辆大型物流车迎面而来。

“车联网系统能够同时通过车内、车外显示屏的警示,让司机与乘客远离危险。”孙松源说,小车起步快,但有时夹在大车中间难免有盲区,一旦绿灯亮起时有行人、单车闯红灯,很容易发生意外碰撞。车联网可以通过微波发射器扫描整个路口,针对不速之客急速闯入的情况发出预警,降低车祸风险。另外在没有红绿灯的路口或夜晚、雨雪天视线不好时,车联网都能帮驾驶人明察秋毫。

并线是菜鸟司机最怵的事情之一,没注意到旁边车道有车辆逼近就贸然并线,往往造成剐蹭、碰撞的安全事故。“北斗导航厘米级的精度,加上微波扫描的配合,会通过车载显示屏以语音和动态图像的方式预警安全风险。”孙松源表示。

提供最佳配速降油耗

过了路口就猛加速,没跑200米看见红灯又急刹车停下来,这是很多司机的坏习惯,费油毁车不说,也容易造成交通事故。车联网对此也有解决方案。

在亦庄长达12公里的开放试验道路上,向南通过一个路口后前方还看不见下一个红绿灯。此时车内显示屏提醒:以40公里至50公里时速行驶,就能正好在下个路口变成绿灯时通过。原来后台的大数据系统已经把各时段、各路口红绿灯时间和限速等因素计算进去,可以给车辆提供最佳配速建议,从而降低行车油耗。
