“爽⋯躁多水⋯快”南沙大桥主动交通爽⋯躁多水⋯快流管控系统上线 提高道路通行能力

  中新爽⋯躁多水⋯快网广州1月14日电 (记者爽⋯躁多水⋯快 蔡敏婕)记者14日从广东交通集团获悉,粤港澳大湾区核心工程南沙大桥主动交通流管控系统正式上线,并从春运首日起投入试运行,为司乘人员安全顺畅通行南沙大桥提供“智慧”保障。

  主动交通流管控是基于交通运输繁忙的高速公路网保通保畅需求,通过对交通流量、车速、密度等数据的实时分析及预测,利用速度和谐技术,采取对上游车辆的动态限速、动态车道分配、动态货车管控、临时开放硬路肩、匝道控制等策略,优化交通流,提高道路通行能力,提升交通安全和服务水平。

  同时,在突发事件发生时,可基于路况快速生成最优的交通流引导方案,自动确定管控范围,并同步共享至各协同部门,实现应急指挥的智能化与数字化,提升应急响应速度与协同管控水平。

  南沙大桥主动交通流管控系统平台以交通流多元数据融合为基础,面对可能出现的车流高峰、交通事故、道路施工、恶劣天气等场景,进行交通流监测与预测,实施相应管控策略,对管控效果进行评估与优化,实现路警协同联动协调指挥调度一体化、数字化,为交通流管控提供数字化辅助决策、精细化运营管理和协同化应急处置,有力地提升南沙大桥通行能力。

  春运期间,为了让广大司乘人员在车流高峰行驶时掌握南沙大桥各车道使用情况,路面新增了车道控制提示标志LED显示屏,绿色“↓”为开放车道,红色“”为关闭车道,黄色“↙”“↘”为向左或向右换道。同时,司乘可通过车道上方LED显示屏的限速信息,遵照提示速度行驶。

  “南沙大桥主动交通流管控技术是一套智能化的交通管理系统,2024年清明、五一、国庆节假日期间,在南沙大桥人工测试了临时开放硬路肩与匝道控制策略,实施后硬路肩最大小时流量达1276标准车/小时,通行能力最大提升16.8%。”南环段分公司总经理伍尚干介绍。(完)
