about the walkable city.
车是一个选择性的代步工具,
is an optional instrument of freedom,
我们需要一个可步行城市,
why we need the walkable city,
去实现一个可步行城市。
how to do the walkable city.
are about why we need it,
都是关于为什么我们需要它,
(一定能猜到答案)。
exactly a month ago,
做过一次类似的演讲,
about how to do it.
the general theory of walkability.
还有点开玩笑的意味。
it's a little tongue-in-cheek,
I've thought about for a long time,
what I think I've figured out.
the typical American city --
is not Washington, DC,
(爱荷华州),或孟菲斯市(田纳西州)。
Rapids or Memphis --
in which most people own cars
is to drive them all the time,
那你需要让步行体验
then you have to offer a walk
four things simultaneously:
of these things simultaneously,
我的导师那里听来的故事,
is a story I learned from my mentors,
Elizabeth Plater-Zyberk,
一半的演讲
and half of my talk today
of the planning profession.
people were choking
我们把居住区搬离磨坊吧。
the housing away from the mills.
immediately, dramatically,
that experience ever since.
欧几里得的分区,
of what we call Euclidian zoning,
into large areas of single use.
去做规划的时候,
in a city to do a plan,
on the property that I'm looking at.
near anything else.
is our most walkable city,
(抽象表现主义风格),
this is a Rothko,
秀拉是一个点彩画派的艺术家——
he was the pointilist --
也有一点误导性,
is a bit misleading
is uses that are mixed vertically.
of the New Urbanists --
are only two ways
in the world and throughout history.
of Newburyport, Massachusetts,
纽伯里波特的几个街区,
and being diverse --
娱乐,接受教育——
recreate, get educated --
after the Second World War,
并且不适宜步行,
and it's not walkable,
become overburdened,
在这样的街区玩耍。
the aerial photographer,
艾利克斯.麦克林,
that I'm showing you today.
这么多美丽的照片。
into its constituent parts.
the places where you only work,
只用来工作的地方,
and further from each other.
of the parking lot
has ever walked to this school,
带着低年级的学生,
the freshmen and the sophomores,
the crash statistics to prove it.
of our other civic institutions
威斯汀(佛罗里达州)
in the Ft. Lauderdale area
and eight baseball diamonds
that takes you to that location,
the soccer mom now.
because it was in my neighborhood.
所有人都忘记考虑了:
that everyone forgot to count:
from everything else
only with automotive infrastructure,
begins to look like.
你不能以扩长的模式开始。
you can't start with the sprawl model.
of that form of design,
that a lot of Americans want.
it's a two-part American dream.
通常比较滑稽的极端情况会发生在
often to absurd extremes,
to accommodate cars first.
考虑交通状况的时候。
of being in these places --
做了这张换灯片。
can be a bit of a nuisance,
can be a bit of a nuisance
展示过一段时间的幻灯片,
have been showing for some time now,
你开着车去停车场,
where you drive to the parking lot
of the New Urbanism now
传统的街区包含同样的东西。
neighborhood contain the same things.
还是死胡同,
rather than a cul-de-sac
of being walkable,
in America's cities
we want the proper balance of uses.
in which most Americans live,
you bring housing back,
among those things.
that shows up last and eventually
成长,有自己的孩子,
get older, have kids
get pretty good eventually.
walkable neighborhood without it.
一个完美的可步行街区。
require transit,
to the whole city as a pedestrian,
around your needs,
and the parking lots get bigger
一个可步行的城市了。
每一次运送的旅行,
every transit trip,
walkability around our transit stations.
运输枢纽打造可步行性。
is the safe walk.
是安全的步行。
experts talk about.
安全是不足以激励人们去步行的。
to get people to walk.
that add up to a walkable city.
famously walkable.
it's almost like two different planets,
像在两个不一样的星球,
当你拥有60米宽的街区城市,
you have a 200-foot block city,
is a six-lane city, and that's a problem.
可以是六车道的,那这就有问题了。
of 24 California cities --
加利福尼亚城市的研究——
the number of fatal accidents
what I tell every audience I meet,
我还要同样
about induced demand.
both to highways and to city streets.
that when we widen the streets
要在什么时候拓宽街道
that we're anticipating,
that we're anticipating
it is principally that congestion
that are ready to happen.
about when they commute,
very quickly with traffic,
and they fill up again.
in congested systems,
有这么一段文字:
hardly an esoteric publication:
usually makes traffic worse."
请让我见一见这些工程师,
may I please meet some of these engineers,
that I'm working with now --
能遇到的典型的工程师,
one typically meets working in a city,
我们需要加一个车道。”
is too crowded, we need to add a lane."
车流就涌上来了,
we needed that lane."
“看吧,我说过我们需要加车道。”
and to city streets if they're congested.
我工作过的美国城市,
about most American cities that I work in,
that are actually oversized
they're currently experiencing.
to me, very upset,
in Prevention Magazine
in the entire country.
to make a mayor do something about it.
at the car counts on the street --
每天可以承载一万辆车。
can handle 10,000 cars per day.
全都几乎接近或低于一万辆车,
they're all near or under 10,000 cars,
that were designated
between the number of lanes
that wanted to use them.
重新设计市区的每一个街道,
every street in the downtown
under construction,
you find room for medians.
就为隔离带腾出了空间。
of on-street parking.
where one didn't exist before.
并不存在的自行车道网络。
that Oklahoma City has,
俄克拉荷马市有足够的资金,
运作良好的提取经济。
economy that's doing quite well.
like Cedar Rapids,
半单向车道系统。
system, half one-way system.
还有一些在建项目,
it's in process right now,
system, half one-way
70 percent more on-street parking,
我们增加了70%的街边停车位,
robust bicycle network.
经久耐用的自行车道网络。
How wide are they?
such that, as Andrés Duany says,
正如安德烈斯杜安尼所说,
to a subdivision in America
the curvature of the Earth.
outside of Washington from the 1960s.
at the width of the streets.
to such a degree
that wasn't draining properly,
and take away half our sidewalk,
but the citizens know it,
他们力争窄的街道。
they fight for narrower streets.
in its residential neighborhood.
在他的项目 I'On中,
in his project I'On,
his amazing 22-foot roads.
他的完美的6.7米路宽。
very narrow rights of way,
that leads to destruction ...
are the current revolution underway
现在都只在部分美国城市
它们就到哪。
but the one thing I can say
但是有一件事我可以确定,
是自行车建设的基础。
is a function of bicycle infrastructure.
纳尔逊尼格公司的朋友汤姆博南
from Nelson\Nygaard in Portland
of the Portland bike commute.
"Was that bike to work day?"
money on bicycle infrastructure --
花费资金在自行车道建设上——
of bikers in it several times now
like Long Beach, California:
像加州的长滩:
大量骑车人数上升。
based on the infrastructure.
here in Washington, DC --
拉姆·伊曼纽尔的新自行车道,
new bike lanes in Chicago,
pulled off the curb,
cars and the curb --
every lane is a bike lane,
每一条道路都是自行车道,
that I met in Pasadena, so ...
遇到的骑自行车的人。
from moving vehicles.
one side of the street, you can park,
街道的一侧,你可以泊车,
slow cars down.
are next to the road,
they slow down very quickly.
他们减速非常快(撞树了)。
比如路缘的曲度。
the curb return radius.
来决定车可以开多快,
how fast the car goes
因为这是客观的报道,
is objective journalism.
is not inviting to pedestrians."
of the landscape is swoopy,
能够为行人友好化铺路。
can be allowed to set the stage.
of the hundred-year storm,
has to mount the curb every day.
每天过马路都需要爬路缘。
行走需要面临一个事实,
has to do with the fact
都要寻找,期待,和躲藏。
prospect and refuge.
但同时也想要感到
建筑能提供一定的遮掩。
that our flanks are covered.
路缘的城市吸引了,
that have good edges,
people won't want to be there.
人们就不会想去哪里。
of height to width?
是合适的呢?
you're not very comfortable anymore.
can be perfectly delightful.
is the principal problem here.
can be issues as well,
那些空旷的位置也可能成为问题,
because of an outdated zoning code,
中间位置出现一个缺口。
in your neighborhood.
这里不可以施工建设。
I couldn't build on that site.
正在对社区进行改造,
is now changing its zoning
to become sites like this.
can be interesting to build,
people generally like it.
这些缺失的空间。
than other people.
it's a great thing.
一个标志性的步行城市,
a very walkable city,
best hotels together,
you have an exposed parking deck,
有一个暴露的停车楼,
you have a conference facility
in admiration for that parking deck,
Mayor of Charleston, South Carolina,
查尔斯顿市市长的第10个任期,
25 feet of building
It's in South Beach.
它在南海滩。
that I love to show.
在俄亥俄州的哥伦布市。
It's in Columbus, Ohio.
neighborhood, full of pedestrians.
少数民族聚集区,
neighborhood -- ethnic,
但却濒临倒闭。
great shops, struggling.
because this was the bridge,
因为这曾经有一座桥,
from the convention center
they added an extra 80 feet to the bridge.
他们为这个桥加宽了25米。
高速路上面重建了这个桥。
over the highway.
has come back to life.
不包括规划杂志,
not the planning magazines,
it's because of that bridge.
这就是可步行性的基本理论。
theory of walkability.
have most of them
in those places.
