“1819岁macbookpro高清”京沪高速(1819岁macbookpro高清四环-五环)拓宽改造工程完工 出京方向车速提升122%

  中新1819岁macbookpro高清网北京12月24日电 (1819岁macbookpro高清记者 吕少威)记者今天从北京市交通委获悉,备受市民关注的京沪高速(四环-五环)拓宽疏堵工程近日已完工。改造工程实现了京沪高速三环至五环全路段由双向4车道增加为双向6车道,打通了亦庄地区与中心城之间的道路瓶颈,有效提高亦庄新城交通可达性,更好地服务亦庄开发区的交通出行,助力亦庄新城高质量发展。

  开通后,北京市交通委城养中心对京沪高速(四环-五环)路段早高峰交通运行状况进行观测分析,道路运行1819岁macbookpro高清速度和通行能力均有较大提升。改造前京沪高速(四环-五环)路段早高峰期间出京方向速度约14.4km/h,开通首日约32km/h,提升122%;改造前早高峰出京方向流量3480辆/h,开通首日为5484辆/h,增加2004辆/h,提升58%,缓堵效果显著。

  京沪高速是亦庄开发区最重要的对外通勤走廊,开发区内居住人口较多,高新企业分布密集,约有35%的交通量经由京沪高速进出亦庄开发区,区域交通与过境交通相互叠加,交通需求大。

  京沪高速三环至四环以及五环以南均为双向6车道,四环至五环段仅设置双向4车道,形成道路瓶颈,尤其是出京方向受四环内环、外环双向2条匝道车辆汇入京沪高速主路的影响,车辆需在短距离内由5车道(主路3车道+匝道2车道)渐变至2车道,导致该路段呈现常态化拥堵状态。

  为减轻京沪高速四环至五环的交通压力,解决亦庄地区出行难问题,北京市交通委会同北京市公安交通管理局、北京亦庄经开区等相关单位反复论证、研究确定了改造方案:在现况道路用地范围内,通过压缩中央隔离带(由3米调整为1.5米)、调整车道宽度(3.75米调整为3.5米)、取消硬路肩(2.5米)的方式,将长约3.5公里路段由双向4车道调整为双向6车道。

  北京市交通委城养中心充分论证交通导行方案、排水边沟改造方案、管线保护方案等关键环节,于2024年8月下旬进场施工。历时四个月紧张施工,完成了管线保护、边沟加固、路面摊铺、交通标志标线施划等施工内容,顺利完成拓宽工程改造。(完)
