"Reasonable Development of Transportation Network" PPT

Part One: Import

What are the transportation options to Lhasa from your hometown? If you travel to Lhasa, which mode of transportation will you choose?

"I stand on a high mountain at dusk, hoping that the railway will be built to my hometown. Giant dragons are crossing the mountains and ridges, bringing health to the snow-covered plateau..." - Song "Heavenly Road"

my country’s railway trunk lines and hubs

1. Reasons why my country is suitable for developing railway transportation.

2. Overview of my country’s railway transportation.

3. Figure 4-3-1, find the Longhai-Lanxin Line, Beijing-Shanghai Line and railway hub Kunming.

Our country has a vast territory, and the transportation volume of people and goods between various regions is large and the transportation distance is long, so it is suitable for the development of railway transportation. Since 1949, our country has always attached great importance to railway construction and made brilliant achievements. By the end of 2010, the national railway operation mileage reached 91,000 kilometers, and the railways reached every provincial administrative region in the mainland, becoming the framework of my country's comprehensive transportation network.

Reasonable development of transportation network PPT, part 2: General rules for naming railway lines:

Starting from Beijing, "京" is in front

Beijing-Baotou Line, Beijing-Harbin Line, Beijing-Shanghai Line, Beijing-Kowloon Line, Beijing-Guangzhou Line

North-south direction, north before south and back

Beijing-Harbin Line, Beijing-Shanghai Line, Beijing-Kowloon Line, Beijing-Guangzhou Line, Jiaoliu Line, Baocheng-Chengdu-Kunming Line, Qinghai-Tibet Line

Go east to west, east to west and back

Binsui-Binzhou Line, Beijing-Baotou-Baotou-Lanzhou Line, Longhai-Lanxin Line, Shanghai-Kunming Line, Nan-Kunming Line

Named after the location of the railway line

Qinghai-Tibet Line, Northern Xinjiang Line, Southern Xinjiang Line

Reasonable development of transportation network PPT, the third part: activities

Be familiar with my country’s main railway lines and railway hubs

1. Select any two railway trunk lines that intersect and name the railway hub formed by the intersection of these two trunk lines.

2. Select any two provincial administrative centers that have railway trunk lines passing through them, and name the railway trunk lines that pass through them and their starting and ending places.

The rapid economic development has made the contradiction between supply and demand of my country's railway transportation always tense. For this reason, my country has always regarded rapid development as one of the goals of railway development. Railways operating at speeds of 200 to 400 kilometers per hour are called high-speed railways. my country's high-speed railway construction began with the Qin (Qinhuangdao)-Shenyang (Shenyang) Passenger Dedicated Line built in 1999. After more than ten years of construction and high-speed transformation of existing railways, as of the end of 2010, the operating mileage of my country's high-speed railways has reached More than 8,300 kilometers. At present, our country already has the world's largest high-speed railway network with the highest operating speed.

Reasonable development of transportation network PPT, Part 4: Characteristics and selection of transportation modes

1. Five main modes of transportation in my country

2. Characteristics of different modes of transportation

According to different means of transportation, modern transportation can be divided into five main modes: railways, highways, waterways, aviation and pipelines. Various transportation lines are intertwined and constitute the "lifeline" of my country's economic development.

Each mode of transportation has its own characteristics and its applicable situations are also significantly different. Railway transportation has large volume and cheap price, and often undertakes long-distance transportation. Road transportation is fast and convenient, and can realize "from door to door" transportation. Road transportation generally undertakes short-distance transportation, but in areas where railway transportation and waterway transportation are underdeveloped, it often also undertakes long-distance transportation tasks. Water transportation is cheap, but is easily restricted by weather, water levels and other natural conditions. Air transportation is fast, but it is expensive, has a small volume, and is easily restricted by weather conditions. Pipelines are mainly used for the transportation of oil, natural gas, etc. They have low losses and are less affected by weather factors. However, the initial construction period is long and the construction cost is high.

Choose the right mode of transportation

1. Combined with the table below, compare the differences between the five modes of transportation in terms of speed, passenger capacity, and fares.

2. Combined with the characteristics of transportation modes, determine which mode of transportation is suitable for the following scenario cases, and make a simple summary.

Reasonable development of transportation network PPT, Part 5: Summary of this lesson

Transportation and us: Transportation realizes the circulation of goods and people, and this circulation is constantly accelerating. Railway transportation has a large volume, good safety, and is less subject to weather restrictions.

Characteristics of transportation modes: road transportation is fast and convenient; water transportation is cheap and susceptible to water level restrictions; air transportation is expensive, has a small volume, and is susceptible to weather restrictions.

Choose transportation method wisely

When choosing a freight method, you should consider what to ship, where to ship, the quantity, how much the freight will cost, how long it will take, etc.

Factors such as speed and fare should be considered when choosing a passenger transport mode.
