双语热点:未来几年,无人驾驶汽车将如何改变我们的世界******

尽管还有许多问题有待解决,但自动驾驶汽车技术正在不断完善,逐步成为人类现实生活的一部分,它可能将以一些意想不到的方式改变我们的世界……让我们一起来看看,在未来2年,5年,7年和10年后的无人驾驶汽车会是什么样?

How driverless cars will change our world

It's a late night in the Metro area of Phoenix, Arizona. Under the artificial glare of street lamps, a car can be seen slowly approaching. Active sensors on the vehicle radiate a low hum. A green and blue 'W' glows from the windscreen, giving off just enough light to see inside – to a completely empty driver seat.

这是亚利桑那州凤凰城(Phoenix)市区的一个深夜。在街灯的强光下,可以看到一辆汽车缓缓驶来。车辆上的传感器发出低沉的声音。一个绿蓝相间的“W”字在挡风玻璃上闪着光,因此刚好能看清汽车内部——驾驶座完全空着。

The wheel navigates the curb steadily, parking as an arrival notification pings on the phone of the person waiting for it. When they open the door to climb inside, a voice greets them over the vehicle's sound system. "Good evening, this car is all yours – with no one upfront," it says.

汽车稳定地在路面行驶,等到有人手机上发出到达指示时,它就停了下来。当乘客打开车门上车后,车内音响系统传来欢迎的声音。“晚上好,这辆车完全是你的——没有人在前排驾驶,”它说。

This is a Waymo One robotaxi, hailed just 10 minutes ago using an app. The open use of this service to the public, slowly expanding across the US, is one of the many developments signalling that driverless technology is truly becoming a part of our lives.

这是一辆Waymo One自动驾驶出租车,10分钟前刚刚用一款应用程序叫到了车。在美国各地,这项服务正在向公众缓慢开放,这是诸多进展之一,表明无人驾驶技术正在真正成为我们生活的一部分。

The promise of driverless technology has long been enticing. It has the potential to transform our experience of commuting and long journeys, take people out of high-risk working environments and streamline our industries. It's key to helping us build the cities of the future, where our reliance and relationship with cars are redefined – lowering carbon emissions and paving the way for more sustainable ways of living. And it could make our travel safer. The World Health Organization estimates that more than 1.3 million people die each year as a result of road traffic crashes. "We want safer roads and less fatalities. Automation ultimately could provide that," says Camilla Fowler, head of automated transport for the UK's Transport Research Laboratory (TRL).

无人驾驶技术的前景一直很诱人。它有可能改变我们通勤和长途旅行的体验,让人们远离高风险的工作环境,并让各行业更高程度的发展和配合。它还是我们建设未来城市的关键。在未来,我们对汽车的依赖以及与汽车的关系将重新被定义——降低碳排放,为更可持续的生活方式铺平道路;我们的旅行也更安全。世界卫生组织估计,每年有130多万人死于道路交通事故。“我们希望道路更安全,死亡人数更少。英国交通研究实验室(Transport Research Laboratory)自动化运输主管卡米拉·福勒(Camilla Fowler)表示。

But in order for driverless technology to become mainstream, much still needs to change.

但要想让无人驾驶技术成为主流,还有很多地方需要改进。

"Driverless vehicles should be a very calm and serene way of getting from A to B. But not every human driver around it will be behaving in that way," says David Hynd, chief scientist for safety and investigations at TRL. "It's got to be able to cope with human drivers speeding, for instance, or breaking the rules of the road."

“无人驾驶汽车应该是一种非常冷静的交通工具,但并不是路上所有人类司机都会这样做,”交通研究实验室安全与调查首席科学家戴维·海恩德(David Hynd)说。“它必须能够应对人类司机各种违反交通规则的行为,例如超速驾驶。”

And that's not the only challenge. There's regulation, rethinking the highway code, public perception, improving the infrastructure of our streets, towns, cities, and the big question of ultimate liability for road accidents. "The whole insurance industry is looking into how they're going to deal with that change from a person being responsible and in charge to the vehicle doing that," says Richard Jinks, vice president of commercial at Oxfordshire-based driverless vehicle software company Oxbotica, which has been testing its technology in cars and delivery vehicles at several locations across the UK and Europe.

这并不是唯一的挑战。制定规则,重新审定高速公路法规,公众意见,改善街道、城镇和城市的基础设施等等都是问题。认定道路事故的最终责任则是更大的问题。“从个人负责到车辆负责,如何应对这种转变,是整个保险行业都在研究的问题。”位于牛津郡的无人驾驶汽车软件公司Oxbotica的商业副总裁理查德·金克斯(Richard Jinks)表示。该公司一直在英国和欧洲多个地区的汽车和配送车辆上测试无人驾驶技术。

The ultimate vision experts are working towards is of completely driverless vehicles, both within industry, wider transport networks, and personal-use cars, that can be deployed and used anywhere and everywhere around the world.

专家们的终极愿景是实现完全无人驾驶,包括运输行业的无人驾驶汽车、更广泛的交通运输体系,以及可以在世界任何地方的个人用车。

But with all these hurdles in place, what exactly does the next 10 years have in store for autonomous vehicles?

即使这些障碍都存在,自动驾驶汽车在未来10年里究竟会有什么发展呢?

Two years from now

两年之内

The biggest hurdle for those in the driverless technology industry is how to get the cars to operate safely and effectively in complex and unpredictable human environments. Cracking this part of the puzzle will be the major focus of the next two years.

无人驾驶技术行业的最大障碍是如何让汽车在复杂且不可预测的人类环境中安全有效地运行。破解这个难题将是未来两年的重点。

At the Mcity Test Facility at the University of Michigan, experts are addressing this. The world's first purpose-built testing ground for autonomous vehicles, it's a mini-town of sorts, made up of 16 acres of road and traffic infrastructure. It includes traffic signals and signs, underpasses, building facades, tree cover, home and garage exterior for testing delivery and ride-hailing, and different terrains such as road, pedestrian walkways, railway tracks, and road-markings which the vehicles must navigate. It's here that experts test scenarios that even the most experienced of drivers may be pressed to handle, from children playing in the street to two cars trying to merge on a junction at the same time.

在密歇根大学(University of Michigan)的Mcity测试中心,专家们正在解决这个问题。这是世界上第一个专门为自动驾驶汽车建造的试验场。它是一个小型仿真城镇,由16英亩的道路和交通基础设施组成,包括交通信号和标志、地下通道、地上建筑物、树木、用于测试送货和叫车服务的住宅,以及不同的地形,如道路、人行道、铁路轨道和各种可能的路况。在这里,专家们测试了一些场景,即使是最有经验的司机也可能会面临压力,比如,孩子在街上玩耍,以及两辆车试图同时并道。

"In order to test driverless technology like this, it depends on hundreds of different variables in any given situation," explains Necmiye Ozay, associate professor of electrical and computer engineering at the University of Michigan. Her solution is to create a group of varied thinkers.

密歇根大学电子与计算机工程副教授尼科米也·欧泽(Necmiye Ozay)解释说,“测试这样的无人驾驶技术,关键在于任何特定情况下数百个不同的变量。”她的解决办法是建立一个由多元思考者组成的团队。

"We're trying to bring people from different parts of the university – not only engineers, but we have people from across disciplines such as psychology, more human-machine-interaction type people, because there are lots of angles to this problem we are trying to solve when it comes to safety," says Ozay. In the facility, Ozay and her team can test different traffic scenarios, as well as explore how autonomous vehicles communicate with each other yet keep vehicle and personal data secure from hackers.

“我们试图将来自不同地区的人聚集在一起, 不仅有大学的工程师,还有其他学科的学者,比如心理学家,更倾向人机交流的专家,因为我们正在努力解决安全问题时,需要多角度思考和推进 ,”欧泽说。在测试中心,欧泽和她的团队不但要测试不同的交通场景,还必须设计自动驾驶汽车之间的相互通信,甚至保护车辆和个人数据不受黑客攻击。

That self-driving taxis are already on the roads in Phoenix, Arizona, is due to a prolonged testing process like the one Ozay's team is conducting. Currently only available as a test service to the public in small defined areas, in the next two years there are plans to release the taxis on a greater and wider scale.

自动驾驶出租车已经在亚利桑那州凤凰城上路,这是基于欧泽团队正在进行的长时间测试。自动驾驶出租车目前只小范围内对公众提供测试服务,但在未来两年内,会在更大范围内推出。

Much of the driverless technology already in use exists in industrial settings like mines, warehouses, and ports, but Hynd believes in the next two years we can expect to see this extended to "last mile delivery". This means the final part of a journey for goods and services – the point at which they are delivered to the consumer. For example, autonomous HGV trucks on motorways or even delivery vehicles for products and groceries.

目前已经在使用的无人驾驶技术大多是在矿山、仓库和港口等工业环境中,但海恩德认为,在未来两年内,我们有望看到这种技术发展到“最后一里路”。这意味着商品和服务旅程的终端部分——交付给消费者的地点。例如,自动载重汽车行驶在高速公路上,甚至是运送产品和杂货的运输车辆。

Five years from now

五年之内

While Apple says it is aiming to launch fully self-driving electric cars four years from now, industry experts are more cautious about what the near-future holds.

虽然苹果公司表示,它的目标是在四年后推出完全自动驾驶的电动汽车,但近期情况让业内专家更加谨慎。

In the next five years most driverless technology will remain behind the scenes. TRL is investigating the potential for driverless HGVs on motorways, including the idea of platooning vehicles. Platoons are a group of semi-autonomous vehicles that drive a close distance between each other, stopping other vehicles from separating them. By driving closer together, vehicles in a platoon can be more fuel efficient by taking advantage of the slipstream of the truck in front while also helping to reduce congestion as the lorries take up less overall space on the road. Also in this space is Plus, the first self-driving truck manufacturer, whose European pilots commenced this year after a successful trial on Wufengshan highway in China's Yangtze Delta economic centre.

在未来五年里,大多数无人驾驶技术仍将无法进入实用阶段。英国交通研究实验室正在研究无人驾驶载重汽车在高速公路上行驶,包括车辆编组。“编组”是将一组半自动车辆近距离行驶,阻止其他车辆将它们分开。靠得更近,车队可以更省油,因为可以利用前面卡车减小的风阻,同时也有助于减少拥堵,因为卡车在道路上所占空间更少。首家自动驾驶卡车制造商Plus也在研发这一领域,该公司今年在中国长江三角洲经济中心五峰山高速公路上进行了成功的试运,其后开始在欧洲试运行。

Away from these industries, Ozay further predicts that "we will possibly see lighter robotic vehicles that can potentially use sidewalks and bike paths with limited speeds – for delivering things such as food and groceries."

除了这些行业,欧泽进一步预测,“我们可能会看到更轻的无人驾驶车辆,可以在人行道和自行车道上低速运送食品和杂货。”

When it comes to public transport, Oxbotica is also working with German-based vehicle systems specialist ZF over the next five years to make the driverless shuttle a true mainstay for European cities, operating on roads, as well as at airports, much in the same way buses do now. "The shuttles in airports we see today on rails won't need those rails in five years from now. This means driverless shuttles have the potential to transport you from the car park to the airport, then straight through to your gate and the plane," Jinks explains.

在公共交通方面,Oxbotica还与总部位于德国的汽车厂商ZF在未来5年展开合作,希望让无人驾驶穿梭车成为欧洲城市的真正支柱,在道路和机场上运行,就像现在的公共汽车一样。“我们今天在机场看到的轨道班车在五年内将不再需要轨道。这意味着无人驾驶穿梭车有可能把你从停车场送到机场,然后直接送到达登机口和飞机,”金克斯解释道。

For users, this could mean more reliable and cost-efficient transport systems. "Interlinking autonomous transport systems to bring a public transport system that is as efficient as you jumping in your own car and driving it yourself has got to be the answer to congestion in the future," adds Jinks.

对用户来说,这可能意味着更可靠和成本效益更高的运输系统。金克斯补充说,“将自动交通系统相互连接起来,出现一个像你自己驾驶一样高效的公共交通系统,这肯定是未来解决拥堵的方案。”

Seven years from now

七年之内

All experts agree that the next seven years will depend on the successes and failures of initial deployments, and how safety and public trust evolves accordingly. However, most hope that city redesigns will enable more adoption of the technology and help move us into modern, and more efficient ways of living. "If you live in a dense, urban area, the hope is that you'd be able to rely on mobility as a service. You could dial up the car, it would arrive in two minutes, and you make your journey. You wouldn't need to have those vast rows of parked cars in your street, which makes the street more navigable for the automated vehicle," says Hynd.

所有专家一致认为,未来七年将决定初始建设的成败,以及安全与公众信任如何相应发展。然而,大多数人希望城市的重新设计能够使人们更多地采用这种技术,帮助我们进入更现代化和高效的生活。“如果你住在人口稠密的城市地区,你肯定希望能够依靠交通服务便捷。你可以打电话叫车,两分钟后车就会到,就可以上路了。街道上不需划大片的停车空间,这使得街道更有利于自动驾驶汽车导航,”海恩德说。

Without parked cars lining the street, roads could be narrower, making way for more green spaces. But while proponents of self-driving vehicles insist they will make our roads safer, there are some who feel pedestrians and autonomous vehicles simply can't mix. It could mean that our cities and the way we use them may need to be reimagined.

没有路边停放的汽车,道路会变得更窄些,便有了更多的绿地。尽管自动驾驶汽车的支持者坚称,自动驾驶会让我们的道路更安全;但也有一些人认为,行人和自动驾驶汽车根本不能混在一起上路。这可能意味着我们的城市可能需要重新构想和规划。

Some of this thinking is already taking place. In 2018, IKEA developed a concept autonomous vehicle that can double up as meeting rooms, hotels, and stores. The impact this type of innovation would have is reduced requirement for travel in the first place, offering instead interchangeable, on-demand environments as and when we need them. Our needs could be met right where we are.

一些想法已经形成。2018年,宜家(IKEA)开发了一款自动驾驶概念汽车,可以兼作会议室、酒店和商店。这种创新首先是减少了对旅行的需求,取而代之的是在我们需要的时候提供可按需变换的环境。我们的需求可以随处得到满足。

10 years from now

10年之内

Despite all the developments and innovations the next decade is likely to hold, some experts still feel we might be a way off from full deployment of driverless vehicles. By 2031, "full-self driving – human-level or above, in all possible conditions, where you can put kids by themselves in the car to send them to arbitrary locations without worrying – is not something I expect to see," says Ozay.

尽管未来10年可能会有各种发展和创新,但一些专家仍然认为,全面部署无人驾驶汽车可能时间还不足。到2031年,“全自动驾驶——意思是在任何变换的情况下自动驾驶都能达到人类或更高水平,你可以把孩子自己放在车里,把他们送到任意地点,而不用担心——我估计这还无法实现,” 欧泽说。

Hynd agrees that full automation is unlikely on this timescale. "With anything transport infrastructure, anything that society uses, so many other things need to come into play. And I don't just mean regulation," he says. Safety will be a major hurdle, especially for countries slower to adopt the change because of the huge costs involved. Infrastructure will also dictate how fast and effectively this technology can roll out, and public perception and willingness to use autonomous vehicles will need to increase according to Hynd.

海恩德认为10年内完全自动化是不可能的。“任何交通基础设施,公共用品,都受其他因素的影响。我指的不仅仅是监管。”安全将是主要的障碍,特别是对于那些改革需付出巨额成本因此较慢的国家。海恩德表示,基础设施也将决定自动驾驶技术的推广速度和有效性,公众对自动驾驶汽车的感知和意愿将需要提高。

But not everyone agrees. Jinks is confident that we'll see autonomous vehicles on the roads at the same time as human-driven vehicles in 10 years from now. In this vein, you may very well be stepping onto a driverless shuttle at the airport, then into a self-driving taxi to take you to your final destination.

但并非所有人都同意这一观点。金克斯相信,10年后,我们将看到自动驾驶汽车和人类驾驶汽车同时上路。按照这种思路,你很可能在机场登上一辆无人驾驶穿梭车,然后坐上一辆自动驾驶出租车,最终到达目的地。

Owning a driverless car in the next 10 years is less likely – it'll still be too expensive for most people, according to Hynd. But the promise of driverless technology is about unchaining us from our reliance on cars, and how that can transform the use of our time and our environment.

海恩德表示,在未来10年内拥有一辆无人驾驶汽车的可能性不大——对大多数人来说,它仍然过于昂贵。但无人驾驶技术的前景在于将我们从对汽车的依赖中解放出来,以及它如何改变我们对时间和环境的利用。

Much in the same way that electric charging stations have slowly entered car parks, side streets, and service stations, so too will autonomous vehicles eventually make their way into our everyday worlds. Years from now, we may well be wondering how we ever lived without them.

就像电动汽车充电站慢慢进入停车场、小巷和服务站一样,自动驾驶汽车最终也会进入我们的日常生活。多年以后,我们可能会回想起没有它们的日子我们是如何生活的。

因山猪成灾 陕西省祭出“杀猪令”:禁猎期缩短到2个月******

  春拱种、夏毁苗、秋啃果是野猪损坏粮食作物的切身体会,对农户导致了非常大的困惑。在中国许多省区,野猪已变成致害范畴最广、导致损害最明显的野生动植物。我国林果业和大草原局在2021年2月,明确了山西省做为第一批防治野猪伤害综合性示范点省区,截止到10月31日,我省共猎捕野猪111头。执行各种赔偿体制兑现和赔付229.85万余元。本应在山林日常生活的野猪为什么经常落山,是栖息地的毁坏或是沒有克星、绿色生态变好造成种群数量快速增加?人们该怎么解决,物种又该怎样科学管控?现在咱们就来科学剖析剖析。

  与生俱来就很强劲。

  野猪分布在欧洲地区、亚洲地区和非州。全球范畴内野猪有8属22种,我国1种7个亚种。我国的大兴安岭地区、吉林长白山、松辽平原、黄淮平原、黄土高原地区及其西部地区和华南地区山坡地均有野猪分布。野猪具备令人震惊的繁殖率、充足的肉食性、强劲的适应力。一只雌虫野猪一年能繁育2次,一胎能生4-12只仔猪。小野猪一年就可生长发育完善,传宗接代。肉食性层面,野猪归属于常见的杂食性动物,绿色植物占有他们食材的90%,叶子、干果、果实、草叶和草根创业都包含以内。他们乃至也吃荤,据陕西省宝鸡陇县群众反映,自己的羊就曾被野猪进攻至死并服用。肉食性繁杂充足使他们更非常容易在野外自然环境中生存出来。此外,不论是严寒或是酷热,不论是山坡地、大草原、戈壁滩、湿地公园或是灌木丛、热带雨林,除开极为旱灾的迪拜和云贵高原高原地区地区,野猪可以融入一切自身能够抵达的各种各样自然环境。

  栖息地降低、沒有克星也是发病原因。

  野猪的伤害以及防治,既是生态问题,也是社会问题。野猪总数的猛增、泛滥成灾,和人矛盾的加重,是生态体系失调的主要表现,从而产生的野猪损害工作人员、危害粮食作物,造成大家一切正常生产制造日常生活纪律遭受明显危害,山西省安康市裴坝村产生野猪致伤事情,造成1死1伤。陕西商洛、延安市黄龙、宝鸡陇县等地野猪常常成群结队落山毁农作物。野猪吃农作物,总得来说仍然是栖息地的问题。栖息地总面积不足、栖息地与田地、人们小区欠缺缓存,这种问题实际上全部的野生动植物都是会碰到,差别仅仅野猪适应能力更强,而其他的小动物会因为栖息地的不够慢慢消声匿迹。不论是海外或是别的有关野猪肇事者的科学研究都发觉,野猪关键偏向于毁坏紧挨着初始栖息地的田地。2000年,我国政府施行“三有保护动物”名册,野猪被列再在其中。擅自猎捕野猪变成违纪行为,再加上国家对不法猎捕个人行为的不断严厉打击,野猪活得无拘无束很是舒适安逸,种群数量瘋狂飙涨;三,因为虎、豹、豺、狼等食肉动物物种消退或降低,造成野猪缺乏克星,种群数量过快提高。

  陕西省减少禁猎期。

  对于人与猪矛盾越来越激烈,山西省公布通知,将野猪禁猎期减少到2个月,由原先每一年3月1日到10月31日调节为3月1日到4月30日。这代表着,每一年3月、4月禁猎野猪,其他十个月可以猎捕野猪。这主要是因为野猪致害通常出现在7月和8月,因此本次调节考虑到在野猪致害最明显的时间段开展猎捕。本次调节禁猎期主要是为了能处理地区老百姓反应的问题,在野猪致害最明显的阶段捕猎,避免给老百姓导致意外伤害和财产损失。尽管禁猎期减少,可是依然必须科学的拟定猎捕计划方案,有效设定猎捕总数,以保持野生植物物种,保持生态体系一致性。扔必须对野猪致害缘故、防控措施开展探寻,以科学的方法来助推物种管控,处理伤害人民人民利益的明显分歧。

  拟定科学防治计划方案。

  拟定科学的治理计划方案,最先必须对本地的野猪种群数量、物种构造、分布及活动内容区域等状况开展调研,把握其集中化分布地区、关键伤害地区和伤害种类,以认真梳理。对于此事,2018年逐渐,陕西省早已对地区的野猪分布及总数开展了全方位的检测。依据《山西省野猪种群数量和分布现况科学研究》,在山西省有野猪分布的县(区、市)为69个,分布区总面积117069km2。我省共分布有野猪128707±16718只,在其中山区地带林地分布有128453±16712只,丘陵地形沟壑区分布有264±10只,平原区荒漠区几乎沒有分布。关键分布于林地与农耕区交叠的林缘地区,在其中秦岭山山区地带、黄龙林及其西山地域分布尤其聚集。对于此事,山西省开设了略阳县、黄龙县、镇安县、岚皋县四个野猪伤害防治试点区,拟定相对应的现行政策,对野猪伤害开展防治。

  在实际防控措施层面,现阶段世界各国对于野猪伤害防控措施关键分成造成了巨大和非造成了巨大:造成了巨大方式关键包含枪击、捕杀、下毒、诱引、狼狗觅食、圈套和套捕;非造成了巨大方式关键包含设定阻碍物、影响技术性、调节栖息地和生物体防控措施,别的防控措施包含熏香剂、食欲不振剂和迁移等。这种方式中的每一种在某种情形下全是有效的,但他们必须资金投入特殊的时长和钱财,而且主要表现出不一样水平的实效性。在陕西省,关键采用造成了巨大和非造成了巨大紧密结合的方法来防治野猪。关键包含:1,应用牧羊犬来猎捕野猪,有一些地区早已进行了狼狗猎捕,可是捕捉率在于狼狗是不是练习素养,与此同时伴随着响声尺寸的提升,捕捉的存活率也会降低;2,人力猎捕,建立并学习培训了专门的猎捕团队,选用捕捉笼或步枪开展诱引猎捕,这一方式存在的不足是猎捕成本费较高;3,一部分农户尝试更改野猪的思想观念和记忆力,让其忘掉吃农作物这一件事儿。假如他们见到田地如同见到人们一样害怕,那麼问题便会处理。关键对策为试着用报警灯、反光贴条、电池充电音响喇叭、唢呐锣鼓、刺金属丝网、弱电安装安全防护网、木围栏、草人、代替性农作物(青储苞米)等多种方法来减少野猪进到田地的次数。

  与时共进,或是要修复野猪克星小动物的当然物种,才有利于从压根清除野猪部分物种太多的安全隐患。“合理猎捕,便是要科学全方位检测野猪的物种动态性,保证捕猎活动内容不造成野猪种群数量降低乃至消退”。
