How does China's highway system compare to the United State’s, and will that change?
I'm posting some pictures and don't want to write words. Pictures are more visual.

中国的公路系统与美国相比如何？这种情况会改变吗？

我上传一些图片让大家看看，不想写文字。图片更直观。

Well, that's all for now

好了，就这些了

Are the Chinese roads better than India, and do the Chinese use concrete roads for powerful structures?

update:

I wonder if any friends from China can recognize where this is.

Tip: This is a minority Autonomous County in southern China.it has a population of about 180000 and an area of 2700 square kilometers. When I went there, it was still a national poverty-stricken county.

中国公路比印度公路更好吗，中国人铺的是否是混泥土公路

我想知道是否有中国朋友能认出这是什么地方。

小贴士：这是中国南方的一个少数民 族自治县。人口约18万，面积2700平方公里。我去的时候，那里还是一个国家级的贫困县。

I don't know about India. Let me introduce China.

A few years ago, I participated in a traffic poverty alleviation work, in short, building roads for poor areas.The national poverty-stricken county I went to has only 180000 people. We plan to build 1000 kilometers of such roads and 79 bridges in 2 years.

我不了解印度。让我介绍一下中国。

几年前，我参加了一项交通扶贫工作，简而言之，就是为贫困地区修路。我去过的国家级贫困县只有18万人。我们计划在两年内修建1000公里的此类道路和79座桥梁

For any natural village, even if there are only a few hundred residents, concrete roads should be guaranteed.

The minimum requirements of design standard are: at least 6m wide, at least 20cm above concrete pavement, 15cm above cement stabilized soil base.

对于任何一个自然村，即使只有几百名居民，也应该保证有混凝土道路通达。

设计标准的最低要求为：至少6米宽，至少高于混凝土路面20cm，高于水泥稳定土基层15cm

China's highway design standards are divided into five levels:

expressway,first-class highway,second-class highway,third-class highway and fourth class highway.

中国的公路设计标准分为五个级别：

高速公路、一级公路、二级公路、三级公路、四级公路。

For the sake of unnecessary misunderstanding, I need to explain:

The “highway” I'm talking about below, in Chinese, refers to the road connecting cities and Townships. The official term is 公路， Literal meaning is public roads.

Standard of Expressway：

为了避免不必要的误解，我这里解释下：

下面我所说的“高速公路”在中文中指的是连接城市和乡镇的道路。官方术语是公路， 字面意思是公共道路。

The following picture is from ya'an-xchang expressway. I participated in this project 16 years ago. Of course, I was just a young technician at that time

下图是雅西高速公路。16年前我参与了这个项目。当然，当时我只是一名年轻的技术人员

Standard of first class highway:

一级公路标准：

Standard of Second-class highway:

二级公路标准

Standard of third-class highway:：

三级公路标准

Standard of Fourth class highway:

四级公路标准

At present, the total length of China's highway is 4.2 million km, and the expressway is close to 120000 km.

目前，中国公路总长420万公里，高速公路近12万公里。

Is there a road in China?
Nope! Not at all: actually people in China travels through aeroplanes and jets.

If anyways they have to go to vendor's shop they make use of choppers and every household has helipads in their terrains.

Even bed tea for them comes from different cities via air route!

中国有路吗？

不！没有！实际上，中国人坐飞机去旅行。

不管怎样，如果他们必须去小店，他们会开直升机，每家每户都有直升机停机坪。

甚至连为他们准备的茶都是从不同的城市空运过来的！

Why are expressways important for India? What are all the advantages of building expressways in India?

The main economic benefits come from faster movement of goods and services. This allows the Indian economy to be more integrated. In turn, this allows for specialization, and becoming larger, with the benefits of scale. It also allows firms to get inputs from multiple sources.

There are also some benefits from personal travel. It’s more convenient to travel by road than by train, provided the drive is not too long. What is too long? That depends upon each person, but distances within 5–6 hours of drive time are quite doable. SO, here is it convenience.

为什么高速公路对印度很重要？

印度修建高速公路有什么优势

主要的经济效益来自商品和服务的快速流动，促进印度经济更加一体化。

也方便个人旅行。只要不是出远门，开车比坐火车更方便。怎么样算出远门？这取决于每个人，不过5-6小时的车程是完全可行的。

What is the difference between highway and expressway?
The difference between a highway and an expressway in India is the access control.

Expressways have controlled access where a vehicle can enter it only through specific entry and ext points which are limited in number. This allows vehicles to move at higher speeds without having to worry about slowing down for signals or crossings.

In the case of highways, there may be multiple roads which merge with/cross the highway at many places.

公路和高速公路有什么区别？

在印度，公路和高速公路的区别在于出入控制。

高速公路有控制通道，车辆只能通过数量有限的特定出入口进入。车辆可以以更高的速度行驶，而不必担心信号灯或交叉口

而普通公路的话，可能有多个交叉路口
