交通记者从北京市交通委获悉，京沪高速（四环-五环）拓宽疏堵工程近日，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，出京方向车速提升122%，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，市交通委会同市公安交通管理局、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（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。新京报记者 裴剑飞SourcePh" style="display:none"
2013年11月，正是在这个大山深处的苗寨院坝，习近平总书记同村干部和村民代表围坐在一起，亲切地拉家常、话发展，首次提出了“精准扶贫”理念。

This map illustrates the OsmAnd routing concept. The route starts in the Start Area Cluster (221558), moves to the nearest Border Point, and continues through precomputed Shortcuts across intermediate clusters. It then enters the Finish Area Cluster (221536) via another border point and finishes using local roads. This method speeds up routing by combining local search with efficient inter-cluster shortcuts.

But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
"There were engineers and managers saying it couldn't be done, all these reasons why it was too dangerous," she says.，这一点在91视频中也有详细论述
