亚特兰大的十字路口——全球交通枢纽选择智能化道路

亚特兰大(美国佐治亚州)最初是一个铁路枢纽,自那以后,它作为交通枢纽的重要性便与日俱增。随着居民和商品的增加,新的想法和萌动也在这座城市大量涌现,许多人扎根亚特兰大,将亚特兰大作为自己的家。跨国公司、大学、投资资金、智能制造以及千禧一代的企业家都在涌入亚特兰大,这座城市的机场成为了世界上最繁忙的机场。 多年来,亚特兰大已发展成为一个向城市外扩张的低密度人口城市:市民一直在增加,却并没有变得更密集,而是向郊区扩张。绿地减少和汽车交通增加对水和空气的质量都产生了影响。所幸,这座城市已经意识到了这个问题,并正采取主要步骤,确保在城市发展和经济增长方面采取更智能化的做法。

向外扩张的都市

亚特兰大市 16 座高度在 150 米以上的摩天大楼展现出其要往高处发展的雄心。这些摩天大楼也可以为可持续发展发挥作用,比如 LEED 认证写字楼——美国亚特兰大桃树街 1180 号。这个引人注目的设计拥有两个超出屋顶上方的侧翼,因此得名“蝙蝠侠大楼”。如果用作居民住宅,这些摩天大楼和中高层的综合体建筑将有助于增加城市密度,控制城市向郊区扩张。

亚特兰大到处都是标志性的建筑,比如美国银行广场 (Bank of America Plaza) 和令人惊叹的梅塞德斯-奔驰体育场 (Mercedes-Benz Stadium),后者融合了柔软的花朵元素和阳刚的几何图案。此外,这座城市的天际线将很快迎来 thyssenkrupp Elevator 的一座闪亮电梯测试塔,它将以 128 米的高度成为美国最高的电梯测试塔。

这座城市也有很多历史建筑,比如伊斯兰建筑风格的福克斯剧院 (Fox Theatre)、亚特兰大历史中心 (Atlanta History Center) 的天鹅之家 (Swan House),以及亚特兰大最古老的摩天大楼——熨斗大厦 (Flatiron building)(比纽约市的同名建筑要早五年完工)。

亚特兰大的智能化和可持续发展雄心

亚特兰大智慧城市规划的重点有五个关键领域:移动性、公共安全、环境可持续性、城市运行效率以及公共和商业参与。在这五个领域中,移动性似乎得到了最广泛的关注,因为它与其他四个领域有许多重叠之处。

亚特兰大计划增加公共交通,同时减少并改善汽车车流。但在交通方面,它并非仅仅关注汽车,而是想在街上推广更多自行车,以期将亚特兰大打造成美国的哥本哈根。亚特兰大环线项目将成为这一愿景的主要推动者,详见下文。

理解,然后行动。

亚特兰大的城市规划者们知道,在部署解决方案之前,他们必须首先了解城市所面临的挑战。所以他们决定从收集和研究实时数据开始。为了获得他们需要的信息,他们在整个城市部署了物联网传感器。

一个大型项目部署了超过 1000 个“智能电线杆”,这些电线杆可以测量空气质量,计算往来车辆、自行车和行人数量。根据城市发行的一项提案申请,他们试图“…通过将电线杆连接至光纤网络,并在电线杆上安装摄像头(计划安装 1100 个联网摄像头)、枪击定位器、空气质量传感器对路灯和交通信号 LED 进行转换,打造智能电线杆和小区天线等相关附着装置”。

这些智能电线杆将有助于城市更好地了解自身的移动性和环境挑战,通过智能交通和互联公共汽车网络改善服务,缓解交通拥堵。

项目亮点:北大街智慧走廊

亚特兰大智慧走廊贯穿该项目研究合作人佐治亚理工学院的校园,覆盖 18 个交通路口和一个地铁站。这个小型的深度项目将有助于发现更大的智能电线杆项目能够实现哪些目标。

亚特兰大前首席信息官 Samier Saini 表示,该系统将“……调整信号时间,然后将该信息延时传递给相邻的交通灯。如果这能对改善交通延时和流动产生重大影响,我们将全力以赴将其部署到城市的其他地区;尤其是部署到那些交通状况糟糕的活动场所。”

Project highlight: North Avenue Smart Corridor

The Smart Corridor in Atlanta runs through the campus of the project’s research partner, Georgia Institute of Technology,  and covers 18 traffic intersections and a metro station. This smaller scale, in-depth project will help discover what the larger smart pole project could achieve.

According to Atlanta’s former Chief Information Officer Samier Saini, the system will “…adjust the signal timing to and then relay that information to adjacent traffic lights. And if that proves to make a significant impact in improving travel time delay and flow, we’re going to go all-in and deploy it in a number of other areas of the city; particularly event spaces where traffic is a nightmare.”

Project highlight: The Atlanta Beltline

With the Beltline project, Atlanta is converting its unused railway lines into a 22-mile transit loop, 28 miles of cross-town transit lines, and 33 miles of multi-use trails – all of which should help better connect the city for pedestrians and cyclists.

The project includes the construction of affordable housing and offers venues for cultural events. Furthermore, it preserves much of the city’s industrial heritage by repurposing buildings and railroad bridges or transforming railroad artifacts into works of art.

Businesses driving change in Atlanta

Atlanta’s smart ambitions are backed by the city’s strong tech community, which have earned the city the nickname of “Techlanta”. Georgia Tech has successfully attracted a number of companies, such as NCR, GE, and Honeywell, to locate their digital innovation centers in Atlanta.

Germany-based thyssenkrupp Elevator has chosen Atlanta as the home for its Research Innovation Center that it runs in cooperation with Georgia Tech, where the first TWIN elevators in the Western Hemisphere will be installed. The company also plans to build its new US headquarters in Atlanta, which will include a 128-meter elevator test tower when completed in 2022.

Techlanta is also the home city of the “billion-dollar startup” Rubicon Global, a smart trash collection company. The company is equipping Atlanta’s waste collection trucks with app-based tracking and communication tools that provide drivers real-time information on routes and service issues, and also collects data to help improve services.
