Distress signal detected in low******

Reuters。

An eruption occurs at the underwater volcano Hunga Tonga-Hunga Ha'apai off Tonga, on January 14, in this screen grab obtained from a social media video.。

A distress signal has been detected in a low-lying Tongan island following the volcanic eruption and tsunami, the United Nations said on Tuesday as the first death was reported.。

The UN Office for the Coordination of Humanitarian Affairs expressed concern for two islands, Mango and Fonoi, after surveillance flights confirmed "substantial property damage" from Saturday's eruption but there had been no contact with residents.。

"An active distress beacon had been detected from Mango," the OCHA said. The island is home to more than 30 people, according to Tongan census figures.。

The agency said extensive damage had been reported on the western beaches of Tonga's main island, Tongatapu, with several resorts and houses either destroyed or seriously damaged and two people were missing.。

No details of the missing were released but the brother of a British woman who was swept away by the tsunami said his sister's body had been found.。

Nick Eleini said the family was "devastated" that Angela Glover had died wile trying to rescue her dogs.。

"Earlier today my family was sadly informed that the body of my sister Angela has been found," Eleini said in a statement.。

Angela Glover, 50, and her husband lived in Tonga where she ran an animal welfare charity providing shelter and rehoming stray dogs.。

"I understand that this terrible accident came about as they tried to rescue their dogs," Eleini said.。

Three days after the eruption, information coming out of the Pacific archipelago is scarce with most communication links severed.。

New Zealand MP Jenny Salesa, whose electorate has a large number of Tongan residents, said everyone was praying for the people of Tonga.。

"They're really just worried about their safety," she told Radio New Zealand.。

"It's basically not knowing whether they are well, not knowing whether any of their family members are missing or (have) been washed out to sea. It's basically that lack of communication that is worrying to people back here in New Zealand."

The New Zealand and Australian air forces conducted surveillance flights over Tonga on Monday and were preparing further flights to carry emergency supplies to the Pacific kingdom.。

The OCHA said that while communication issues meant they could not fully assess the impact of the eruption and tsunami, there was concern about the contamination of drinking water and crops, and the need for safe water supplies.。

“治堵绿波”上线 延平门地铁站施工区域拥堵状况明显缓解******4cbc0fa0-eb8e-4854-9b67-5c157351b863.jpg (1).jpg

  “治堵绿波”方案

  近期有市民发现,沣惠南路与科技路南出口由原来的5车道变为3车道,早高峰交通压力很大。3月22日,记者了解到,经过一周的调研,西安公安交警在该路口创新推出“治堵绿波”,通过绿波优化和区域信号灯联网控制,为高新区早高峰缓堵。

  两组“治堵绿波”拥堵路段上岗服务

  据介绍,地铁8号线延平门站主体施工期间需临时占用沣惠南路(科技路——枫叶新都市小区东门段)由北向南部分道路。目前南出口由3条机动车道,1条非机动车和1条人行道组成导改路,来保障此处的通行。

  沣惠南路与其东侧的唐延路是高新区的南北大动脉。唐延路由南向北单行,是高新区进入二环和西绕城的重要干道。沣惠南路由北向南单行,与西二环、南二环相通,是二环车流去往高新区的重要通道。高新区写字楼、工厂、学校较多。西安公安交警大数据显示,这里早高峰出行需求大,出行时间较为集中,且具有一定的“潮汐”性。

  施工期间,沣惠南路和科技路十字南北方向的道路都因围挡变窄,如何破解随之而来的拥堵?市公安局交警支队秩序处工程队队长张森说:“此前交通部门已发布了绕行方案,但因围挡及绕行对区域路网影响较大,为了有效治堵,我们调研后决定在该交叉口附近区域通过智能红绿灯赋能,开通东向西和南向北的两组单向绿波,以及信号灯区域联网调控,通过精准治堵,缓解围挡周边区域的通行压力。”

  调研数据显示,拥堵情况主要出现在早高峰时段的东向西方向和北向南方向,“这两组‘治堵绿波’一组将出现在大寨路、科技路的东向西方向,另一组在沣惠南路、团结南路、丈八北路区域的北向南方向。按照缓进快出的控制策略,可保证从西二环、南二环下来的车辆快速通过大寨路继续向西行驶,完成分流;另一部分车流从沣惠南路与科技路北口右转向西行驶到团结南路与科技路交叉口左转,以达到南下的目的,提高北向南的车流通行效率。”

  通过远端调控力争实现缓行不堵

  因围挡区域辐射周边多个十字路口,工程队联网调控了周边沣惠南路与科技路十字、唐延路与科技路十字、团结南路与科技路十字的智能红绿灯,通过远端调控力争实现缓行不堵的效果。

  市公安局交警支队秩序处工程队教导员贾茹说:“沣惠南路与科技路十字,东西和南北车流量都很大,调整后我们为北向南绿灯时长增加了5秒。因唐延路与科技路十字和沣惠南路与科技路十字距离不足150米,为保证驶入与驶出车流量匹配,避免拥堵干扰到南北车流通行,我们在这里增加了5秒绿灯时长。为了确保拥堵点的车辆少进快出,我们在团结南路与科技路十字增加了17秒的东向西绿灯放行。虽然都是几秒钟的调整,但这一套组合拳打下来,能有效提高此路段的通行效率。优化后,地铁8号线延平门地铁站施工区域拥堵状况明显缓解,北向南排队长度由490米降至455米,早高峰持续时间由2小时40分下降至2小时。”

  调研数据显示,施工区域早高峰的车流量比较集中,问题更突出。此次调整中,西安公安交警在早高峰调控上做足了功夫,通过分秒必争的精细化管理,力争缓行不堵的效果。晚高峰因为车流量相对分散,所以只对具体点位做了调整。

  西安公安交警建议途经施工区域的车辆、行人,按照交通标志、标线指示通行或提前择路绕行。随后,西安公安交警将继续加强对此处的监控,随时根据新情况做出相应的缓堵治堵调整。
