How COVID19 reshaped our cities overnight

Transcriber: shirin etebar

When you think of most cities in the US,
images like this come to mind.

Little green space,
lots of fast moving cars,

bumper to bumper traffic
and humans, waiting at curbs

and crosswalks clearly outranked
by the automobile.

Since the dawn of car culture,

urban transportation planning has been
fixated on moving automobiles quickly.

Now, one third of all the land
in cities is set up for cars.

We add lanes to six lane highways.

We cut down trees to widen
to lane residential roads.

We pave over scarce open space
for surface parking.

Many car owners effectively pay double
to reserve up space at home and work.

Providing for cars was
a massive investment

and has provided us immeasurable
flexibility in how we travel.

But our dependence on them.

The costs, the noise, the pollution
have taken a toll on us.

We can now do better.

And, here is how,

I’ve been studying transportation
and environmental design for 25 years.

I’ve encouraged designers, engineers,

decision makers and the public to look
beyond our current car’s model.

But widespread change has
been slow to come.

And then covid-19 hit
and we went into lockdown.

Conventional rules that kept
the auto at the top of the heap

were ditched almost overnight.

We opened up our streets for people
walking in the middle of them.

We open them up for outdoor dining.

And those emerging techie modes
of getting around town,

this meant more room for regular bikes,

electric bikes and all forms of wheel
devices that are cleaner,

lighter and more convenient than cars.

Signs like this one up.

Scenes like this appeared using
street space to preserve physical

and mental health became an imperative.

Now, many cities have been trying their
hand at alternative street designs

For decades, these initiatives
gain some traction

and natural experiment was unfolding.

What happens when cars take
a backseat to people?

It propelled my colleague and me to start
studying these changes

in 55 of the largest cities in the US.

And what we found is thrilling.

The cities that are innovators in our
study are closer to finding solutions

to some of the most pressing and
challenging problems of our time,

like climate change, equity, safety.

Seattle was one of the first
to jump into action.

I was on their bicycle advisory board
20 years ago

with Bill Nye, the Science Guy.

For decades, they’ve dealt with
their crumbling auto infrastructure,

all those bridges and viaducts.

They long been striving to bring more
equitable access

to more people on the streets.

Shortly after the lockdown,

the city unfurled a 30 page playbook
to use their street space better.

A few weeks later, 26 miles of streets
were closed to through car traffic,

opening them up for people
on foot and bike.

The city chose these particular areas

because they were underserved by existing
pedestrian and bicycle infrastructure,

and they were in neighborhoods that were
experiencing more of the impact

from the pandemic, both from a health
perspective and an economic perspective.

A month later, the city mayor
of Seattle announced

the 20 miles of these streets were going
to be closed to cars permanently.

City engineers that are now working
with neighborhood groups,

volunteer based organizations like
Neighborhood Greenway’s

to bring together residents in designing
alternative visions for streets.

Over the summer, on the other
side of the country,

Pittsburgh rolled out a bike plus plan.

As the number of people opting
to block in bike exploded,

this plan enabled the city to slow down
car traffic on even more streets.

Now, Pittsburgh has a long standing
commitment to innovation,

and this bike plus plan helps usher
into the transportation system,

new innovative forms of mobility.

It might be that dusty Schwinn
hanging on the garage,

now refurbished with battery power,

a cargo bike or an electric
three wheeled variant of a bike

that provides more comfort, safety
or protection from the weather.

You see these types of modes.

They can serve mostly the same purpose
as cars, trucks, SUVs,

but they do so using a third
of the space to get around.

And these new modes, they can be great for
older people or those without a car

so that they can run errands
or visit friends.

You see, Pittsburgh is redesigning
their city streets now

to accommodate more of
these human-scale vehicles.

They’re doing so by dropping
the average speed limits

on select streets from
30 miles per hour to 20.

This 10 miles per hour difference in
the case of a crash can save lives.

And what we’re seeing is that they’re
redesigning 50 miles of streets

over the next two years to bring in
more welcoming environments

for bike plus type vehicles.

And, in so doing, they’re ensuring
that technological advances

meet the needs of humans and not cars.

Further, the bike plus plan
is helping the city

reduce transportation related
emissions 50 percent by 2030,

all while expanding affordable access
to jobs and destinations.

I’m excited to keep an eye on Pittsburgh
as they share lessons

for St. Transformation’s with
other cities moving forward.

We also looked at Austin, Texas,

a city always on the fastest
growing cities list.

Now, that growth can be good,
but the residents have felt the strain.

They, too, launched a healthy
streets program,

opening up select streets to
just walking and cycling.

Now, this action proved valuable in
helping residents realize and broaden

the benefit of their tax dollars that
typically pay to serve cars.

New designs were implemented
on South Congress,

the iconic main street of Texas
in downtown Austin.

We see in these historic photos how
the stretch of road has changed.

Character over time evolve with
advances in technology,

civic priorities or public preferences.

With city councils direction,

this stretch of road now has two
fewer lanes of car traffic.

A third of the street space was given over
to people bicycling and rolling

on scooters, taking them off the
busy sidewalks, better suited for dining

under the oak trees, and giving them
increased comfort and safety.

Austin residents recently
and overwhelmingly

approved more than seven billion dollars

in an unprecedented bond referendum,

a nice chunk of which is going to just
transform streets

for active mobility and safety.

Hundreds of low cost,

high impact projects are going to
help build out a new bicycle

and pedestrian infrastructure for
residents of all ages and abilities.

Seattle, Pittsburgh, Austin and
other leading communities,

they’ve all done the research.

More than half of all car trips
in urban and suburban areas

are less than four miles.

Think about a trip to the grocery store,
to the gym, or grab a bite to eat.

Unlike a few years ago, we now
have more mobility options

for these short hops to be easily
satisfied using vehicles

that are lighter, cleaner and greener.

Now, we didn’t need a pandemic

or 80 percent reduction in our local
economies to realize that our love affair

with cars has lost its luster,

but the public emergency
help spur quick change.

We can now build on this momentum
and push it further.

You see, covid-19 has
allowed us to time travel

to see what our cities
would be like in 10 years

when there’s other ways of
getting around town

and the car is not always king.

We’re past sitting indifferent

as multiton vehicles go hurling
by our homes at highway speed.

Cars are too big for these short trips.

We don’t need insulated hiking boots
to attend ballet class

within 20 minutes of where
most of us live.

That is, in our existing communities.

We already have the goods and services
that we access on a daily or weekly basis.

Streets are the single largest
physical asset in cities.

They are owned by the public and we can
get more out of them to achieve our goals.

But to do so, we need to
open up our aperture.

And look beyond having them
always be set up for cars.

Rethinking streets ramps up our climate
crisis plans nationwide,

it draws into focus how these
spaces are engines

for equity by adopting new formula

for how infrastructure resources can be
spent to increase accessibility for all.

And let’s not lose sight of another
public health crisis,

the number of people who die
in car crashes

equal to a Boeing 737 going down
every other day.

The city actions that have just described.

Document how streets can change

to accommodate emerging
cost effective solutions,

all while out without
sacrificing much comfort,

convenience or accessibility.

One hundred years ago, as cities were
grappling with issues of clean water

and safe housing, streets were handed
over to relatively narrow goal

of maximizing vehicular traffic flow.

Now, owing to technological, economic
and environmental change,

we hold in our hand the prospects
for a much brighter future.

And we know how to get there.

We’re in a once in a century situation
with the pandemic.

We have the public’s attention.

Repurposing streets by inviting smaller
vehicles into our lives

and deemphasizing cars is possible.

The evidence shows us that in the
long run we’ll save money, lives

and we’ll make our communities more
just and resilient. Thank you.

当您想到美国的大多数城市时,就会想到这样的
图像。

狭小的绿地,
大量快速行驶的汽车,

交通繁忙的交通
和人类,在路边

和人行横道上等车
,这明显超过了汽车。

自汽车文化诞生以来,

城市交通规划就一直
专注于快速移动汽车。

现在,城市中三分之一的土地
是为汽车设立的。

我们在六车道高速公路上增加车道。

我们砍伐树木以
拓宽住宅道路。

我们为地面停车位铺平了稀缺的开放空间

许多车主实际上支付了双倍的费用
来预留家庭和工作空间。

提供汽车是
一项巨大的投资

,为我们的出行方式提供了不可估量的
灵活性。

但是我们对他们的依赖。

成本、噪音、污染
对我们造成了影响。

我们现在可以做得更好。

而且,这就是

我研究交通
和环境设计 25 年的方法。

我鼓励设计师、工程师、

决策者和公众
超越我们当前的车型。

但广泛的变化
来得很慢。

然后covid-19来袭
,我们进入了封锁状态。


汽车保持领先地位的传统规则

几乎在一夜之间就被抛弃了。

我们为
走在其中的人们开辟了街道。

我们将它们开放用于户外用餐。

而那些新兴的技术人员
出行方式,

这意味着普通自行车、

电动自行车和

比汽车更清洁、更轻、更方便的各种形式的车轮装置有更多的空间。

像这样的迹象。

像这样的场景出现在使用
街道空间来保持

身心健康成为当务之急。

现在,许多城市一直在
尝试替代街道设计

几十年来,这些举措
获得了一些牵引力

,自然实验正在展开。

当汽车坐在人们的后座时会发生什么

它促使我和我的同事开始
研究

美国 55 个最大城市的这些变化。

我们发现的是令人兴奋的。

我们研究中的创新城市
更接近于为我们这个时代

一些最紧迫和最具
挑战性的问题找到解决方案,

比如气候变化、公平、安全。

西雅图是
最早采取行动的国家之一。

20 年前

,我和科学专家比尔·奈(Bill Nye)一起加入了他们的自行车顾问委员会。

几十年来,他们一直在
处理摇摇欲坠的汽车基础设施,

所有这些桥梁和高架桥。

长期以来,他们一直在努力让更多人在街头
获得更公平的机会

封锁后不久

,该市展开了一本 30 页的手册,
以更好地利用他们的街道空间。

几周后,26 英里的街道
被禁止通行汽车,


步行和骑自行车的人开放。

该市之所以选择这些特定区域,

是因为现有的
行人和自行车基础设施服务不足,

而且从健康角度和经济角度来看,它们所在的社区
受到大流行的影响更大

一个月后,
西雅图市市长宣布

这些街道的 20 英里
将永久禁止汽车通行。

城市工程师现在正在
与社区团体、社区绿道

等志愿者组织合作

,将居民聚集在一起,
为街道设计替代愿景。

整个夏天,在该国的另
一边,

匹兹堡推出了自行车加计划。

随着选择
骑自行车的人数激增,

该计划使该市能够减缓
更多街道上的汽车交通。

现在,匹兹堡长期以来一直
致力于创新,

而这个自行车加计划有助于
将交通系统引入

新的创新出行方式。

可能是
挂在车库上的尘土

飞扬的施温,现在用电池供电,

一辆货运自行车或一辆电动
三轮自行车变体

,提供更多的舒适性、安全性
或不受天气影响。

您会看到这些类型的模式。

它们的用途
与汽车、卡车、SUV 大致相同,

但它们使用了三分之一
的空间来四处走动。

这些新模式非常适合
老年人或没有车的人,

这样他们就可以跑腿
或拜访朋友。

你看,匹兹堡现在正在重新设计
他们的城市街道,

以容纳更多
这些人类规模的车辆。

他们通过将

选定街道的平均速度限制从
每小时 30 英里降低到 20 英里来做到


一点。在发生碰撞的情况下,每小时 10 英里的差异可以挽救生命。

我们看到的是,他们将在未来两年内
重新设计 50 英里的街道

为自行车加型车辆带来更宜人的环境。

而且,这样做,他们
确保技术进步

满足人类而不是汽车的需求。

此外,自行车加计划
正在帮助该市到 2030 年

将与交通相关的
排放量减少 50%

,同时扩大负担得起
的就业机会和目的地。

我很高兴能密切关注匹兹堡,
因为他们

与其他城市分享 St. Transformation 的课程

我们还研究了德克萨斯州奥斯汀市,

这个城市一直在增长
最快的城市名单上。

现在,这种增长可能是好的,
但居民已经感受到了压力。

他们也启动了一项健康
街道计划,

将选定的街道开放给
步行和骑自行车。

现在,这一行动在
帮助居民实现和

扩大他们
通常用于服务汽车的税收收益方面被证明是有价值的。

新设计在

德克萨斯州奥斯汀市中心的标志性主要街道南国会实施

我们在这些历史照片中看到了这
条路是如何变化的。

随着
技术、

公民优先事项或公众偏好的进步,性格会随着时间的推移而发展。

在市议会的指导下,

这条路现在
少了两条车道。

三分之一的街道空间
让人们骑自行车和

骑滑板车,让他们离开
繁忙的人行道,更适合

在橡树下用餐,并增加他们的
舒适度和安全性。

奥斯汀居民最近

在一场史无前例的债券公投中以压倒性多数通过了超过 70 亿美元的公投,

其中很大一部分将仅仅
改变街道

的主动流动性和安全性。

数百个低成本、

高影响力的项目将
帮助为所有年龄和能力的居民建造新的自行车

和行人基础设施

西雅图、匹兹堡、奥斯汀和
其他主要社区,

他们都做过研究。 在城市和郊区,

超过一半的汽车行程

不到四英里。

想想去杂货店
、健身房或吃点东西。

与几年前不同,我们现在
有了更多的出行选择,

让这些短途旅行更容易

满足使用更轻、更清洁、更环保的车辆。

现在,我们不需要大流行

或当地经济减少 80%
就可以意识到我们对汽车的热爱

已经失去了光彩,

但公共紧急情况
有助于促进快速变化。

我们现在可以在这一势头的基础
上再接再厉。

您会看到,covid-19
让我们能够穿越时空

,看看我们的城市
在 10 年后会是什么样子,

那时还有其他的出行方式,

而汽车并不总是王道。

当多吨重的车辆
以高速公路的速度从我们家中飞驰而过时,我们已经不再无动于衷了。

对于这些短途旅行来说,汽车太大了。

在我们大多数人居住的地方 20 分钟内,我们不需要绝缘登山靴
来参加芭蕾舞课

也就是说,在我们现有的社区中。

我们已经
拥有每天或每周访问的商品和服务。

街道是城市中最大的单一
实物资产。

它们归公众所有,我们可以
从它们中得到更多来实现我们的目标。

但要做到这一点,我们需要
打开我们的光圈。

并且超越让它们
始终为汽车设置。

重新思考街道在全国范围内加强了我们的气候
危机计划,

通过采用新的公式

来确定如何使用基础设施资源
来增加所有人的可及性,从而使人们关注这些空间如何成为公平的引擎。

我们不要忽视另一场
公共卫生危机,

死于车祸的人数

相当于每隔一天坠毁的波音 737

刚才描述的城市行动。

记录街道如何改变

以适应新兴的具有
成本效益的解决方案

,同时又不
牺牲太多的舒适性、

便利性或可达性。

一百年前,随着城市
努力解决清洁用水

和安全住房问题,街道被
移交给了相对狭窄的目标

,即最大限度地增加车辆流量。

现在,由于技术、经济
和环境的变化,

我们掌握
着更加光明的未来。

我们知道如何到达那里。

我们正处于百年一遇
的大流行病中。

我们引起了公众的注意。

通过邀请小型
车辆进入我们的生活

并不再强调汽车来重新利用街道是可能的。

证据表明,从
长远来看,我们将节省金钱和生命

,我们将使我们的社区更加
公正和有弹性。 谢谢你。
