In recent years, the construction of high-speed rail in Zhejiang Province has continued to develop rapidly, and the scale, coverage, accessibility and service level of the road network have been continuously improved. However, there are still problems such as horizontal high-speed rail gaps in eastern Zhejiang and southwest Zhejiang, inconvenient westward travel from Taizhou, Ningbo and other regions, and weak linkage of tourism resources, which are difficult to adapt to the development requirements of high-quality construction of common prosperity demonstration zones in Zhejiang Province.
Jintai high-speed railway is located in the territory of Jinyi and Ningbo metropolitan areas in Zhejiang, and is the connecting line of Shanghai-Kunming corridor, coastal passage, Hangzhou-Shaoxing-Taiwan railway, Hangzhou-Wenzhou high-speed railway and other road network trunk lines and regional intercity railways.
The purpose of this paper is to study the importance of the functional positioning and construction of the Jintai high-speed railway from the aspects of strengthening the network, improving the level of transportation services, and driving the high-quality development of tourism and regional economy along the line, so as to provide a scientific basis for promoting the inclusion of the project in the planning and implementation as soon as possible.
Schematic diagram of Jintai high-speed rail (**network, for illustration only).
The Jintai high-speed railway is located in the southeast of Zhejiang, connecting the cities of Jinhua and Taizhou, with a design speed of 350km h.
The line leads from the Jinyi Station of the proposed Jinyi Intercity Railway, passes through Jinhua Dongyang City and Pan'an County, and then introduces the Tiantaishan Station of the Hangzhou-Shaoxing-Taiwan High-speed Railway, connects with the Hangzhou-Shaoxing-Taiwan Railway into the urban area of Taizhou, and then extends to the east, and finally reaches the Sanmen East Station of the planned Ningbo-Taizhou-Wenzhou High-speed Railway, with a total length of 17077km。
In 2022, Zhejiang's railway mileage will be 3,663km, including 1,880km of high-speed rail, basically forming a "four vertical and four horizontal" railway main skeleton pattern, building a 1 2h high-speed rail traffic circle from Hangzhou to the Yangtze River Delta and major cities in the province, realizing full coverage of railways in 10 prefecture-level cities (except Zhoushan) in the province, and comprehensively improving the quality of railway services in the province.
In addition, Zhejiang Province also has Hangzhou-Wenzhou high-speed railway, Hangzhou-Quzhou railway, Shanghai-Suzhou-Lake railway, Quli railway, Yongzhou-Zhou railway, Yongjin railway and other high-speed and general-speed railways under construction, and the Zhejiang railway network will be more perfect after completion. The main skeleton layout of the existing "four vertical and four horizontal" railways in Zhejiang Province is shown in Table 1.
The Medium and Long-term Layout Plan of Zhejiang Provincial Railway Network (2022-2050) proposes to form the main skeleton of "five vertical and five horizontal" passenger transport networks and "four vertical, four horizontal and multi-linked" freight networks during the "14th Five-Year Plan" period, and build a one-hour railway traffic circle from Hangzhou to major cities in the province and the central city of the Yangtze River Delta, and a three-hour railway traffic circle to the Haixi Economic Zone and the urban agglomeration in the middle reaches of the Yangtze River, so as to realize the province's 11 prefecture-level cities and many counties to reach the railway or have railways under construction.
Zhejiang Province plans to "five vertical and five horizontal" passenger transport network and "four vertical and four horizontal" freight corridors as shown in Table 2 and Table 3.
The per capita railway operating mileage in Zhejiang Province is 56km and millions of people, and the scale of the road network accounts for 2 percent of the country4%, and the annual passenger traffic accounts for 69%, the size of railway infrastructure does not match economic development.
The Shanghai-Kunming corridor has been operating at full capacity for a long time, which cannot meet the continuous growth of passenger and freight demand; The technical standards of the existing Ningbo-Taizhou-Wenzhou Railway and Wenfu Railway are low, which is inconsistent with the strategic positioning of the national coastal corridor.
In some areas of Zhejiang Province, especially in the southwest of Zhejiang, many counties (cities) still have no railway coverage, which does not match the construction of Zhejiang Province Common Prosperity Demonstration Zone.
There are 8 longitudinal high-speed railways in the region, including Nanjing-Hangzhou high-speed railway, Nanjing-Hangzhou second channel, Shanghe-Hangzhou high-speed railway, coastal high-speed railway, Hangzhou-Shenzhen railway, Hangzhou-Shaotai railway, Hangzhou-Wenzhou high-speed railway, and Hangzhou-Li high-speed railway, and only 3 horizontal high-speed railways, including Hangzhou-Huangzhou high-speed railway, Shanghai-Kunming high-speed railway, and Hangzhou-Qu railway, all of which are located in the central and northern parts of Zhejiang.
The near term is 2035, and the long term is 2045.
Recently: Hangzhou-Wenzhou high-speed railway, Hangzhou-Qu railway, Hangzhou-Li high-speed railway, Ningbo-Taizhou-Wenfu high-speed railway, Jinyi intercity, Jinqu intercity, Quli railway, Ningbo-Jin railway, Jinjian railway, Wenyu railway, Shanghai-Ningbo railway have been completed.
Long-term: Improve the regional road network according to the transportation demand.
The Jintai high-speed railway and the Jintai railway together constitute the Jintai Corridor, and the traffic volume of the project is reasonably determined according to the passenger volume of the channel and the division of labor of each line in the channel.
The traffic volume of the channel is carried out according to the basic idea of the four-stage method, which is divided into railway trend passenger flow, highway transfer passenger flow and induced passenger flow respectively.
1) Trend volume**.
According to the geographical location of the Jintai Corridor and the connection relationship with the surrounding road network, the Jintai Railway Corridor is mainly responsible for the intercity passenger flow between Yongtai and western Zhejiang, Taizhou and Hangzhou, parts of southern Jiangsu, and Jinhua, Quzhou and Shaoxing. It undertakes some medium and long-distance passenger flows in Yongtai and Anhui, Hunan, Hunan, and Hubei, southwest and northwest regions.
In 2019, the railway passenger exchange between Yongtai and western Zhejiang, northern Jiangxi, Hunan and Hubei, southern Anhui, southwest and northwest parts of the country was 5.98 million, with 15.89 million and 20.37 million in the near and long term.
Among them, the Jintai Passage bears 8.28 million people and 10.79 million people, including three parts, one is the transfer of part of the passenger flow of the Taizhou bypass coastal railway to the Jintai Channel, with 4.33 million people and 5.65 million people in the near and long term; the second is the passenger flow from Ningbo to Jintai channel, with 2.78 million and 3.61 million people in the near and long term; Third, the passenger flow from Quzhou and Jinhua to Shaoxing was transferred to the Jintai channel, with 1.17 million and 1.53 million people in the near and long term.
2) Transfer volume**.
The idea of "four-stage method" is adopted, the service characteristics of highways and railways in the channel are calibrated when there is a project, the logit model is used to divide the modes, and the sharing rate of each mode is obtained.
In 2019, the maximum cross-sectional passenger flow density of Taizhou-Jinhua Highway was 12.13 million people, and the average annual passenger flow density of Jintai Passage Highway was 22.12 million and 24.54 million when there was no Jintai high-speed railway in the near and long term, and the proportion of passenger traffic transferred to the railway in the near and long term was 187% and 189%。
Road transfer passenger traffic** is shown in table 4.
3) Induce increased volume**.
According to the principle of "with or without comparison", the gravity model is used to calculate the induced increase rate and induced OD passenger flow, and the induced passenger flow in each section is **. Induce customer flow** See Table 5.
4) Volume summary.
According to the trend, transfer and inducement of passenger flow**, the passenger traffic of the Jintai Corridor is summarized, as shown in Table 6.
5) Research on the division of labor of each line in the channel.
The Jintai Corridor is composed of the Jintai Railway and the Jintai High-speed Railway, of which the Jintai Railway undertakes all the freight volume and the general speed passenger flow, and the Jintai High-speed Railway undertakes all the rapid passenger flow. According to the division of labor of the channel, the distribution of passenger flow density in the two-line section is shown in Table 7.
6) Analysis of passenger flow characteristics.
It is dominated by cross-line passenger flow. The line is mainly responsible for cross-line rapid passenger exchanges between Taizhou, Ningbo and Hangzhou, as well as some areas of Yuanyuan, southern Anhui, northern Jiangxi, Hunan-Hubei, southwest and northwest; It undertakes the rapid passenger exchange between Taizhou and western Zhejiang. **The proportion of cross-line passenger flow in the near and long-term Hengdian-Tiantai section is 675% and 690%。
Undertake part of the tourist flow. The line is to create a tourism economic belt along the first tourism line, tourism passenger flow in a certain proportion of passenger traffic. The near-term and long-term passenger flows of the Hengdian-Tiantai section were 3.97 million and 4.82 million, of which the tourist flows were 1.7 million and 2.3 million, accounting for 13 of the total passenger flow, respectively9% and 148%。
According to the "Medium and Long-term Layout Plan of Zhejiang Railway Network (2022-2050)", Zhejiang Province will focus on building a passenger transport network of "five verticals and five horizontals", of which the "five horizontal" corridor Zhongtai Jinqu Corridor is composed of Jintai high-speed railway and Jinqu intercity.
The Jintai high-speed railway is an important part of the Taijinqu corridor connecting eastern Zhejiang to southwest Zhejiang in the railway network of Zhejiang Province.
The multi-level rail transit plan for the Yangtze River Delta region proposes to build a multi-directional high-speed railway corridor and a long-term layout of the Jinhua-Taizhou railway. As an integral part of the Yangtze River Delta intercity rail transit network, the Jintai high-speed railway horizontally connects the coastal railway, the Hangzhou-Taiwan high-speed railway, the Hangzhou-Wenzhou high-speed railway, and the Shanghai-Kunming corridor, greatly improving the connectivity and flexibility of the road network.
At the same time, the Jintai high-speed railway will closely connect the two metropolitan areas of Ningbo and Jinyi, and is an important project for the interconnection of the four major metropolitan areas in Zhejiang.
The Jintai high-speed railway connects the Jinyi metropolitan area, the greater Nanchang metropolitan area, the Changsha-Zhuzhou-Tan urban agglomeration, the Sichuan-Chongqing urban agglomeration and other metropolitan areas and urban agglomerations to the west, and connects the Ningbo metropolitan area through the existing Hangzhou-Taiwan high-speed railway, the existing coastal railway and the planned Ningbo-Taizhou-Wenfu high-speed railway to the east, which can form a connecting line between the Shanghai-Kunming channel and the coastal channel, and undertake some medium and long-distance rapid passenger exchanges between Taizhou, Ningbo and Anhui, Hunan, Hunan, Hubei and southwest and northwest regions.
Among the "metropolitan areas" in Zhejiang Province, the Ningbo metropolitan area includes the three cities of Ningbo, Zhoushan and Taizhou, and the Jinyi metropolitan area includes Jinhua urban area and Yiwu.
At present, there is still a gap in the high-speed rail in the Jintai channel in the main skeleton of the "four horizontal and four vertical" railways in Zhejiang Province.
The Jintai high-speed railway is a high-speed railway in the Jintai Corridor and a fast track for the westward exit of the Ningbo Metropolitan Area, which fills the gap of the high-speed railway in the Jintai Corridor and is an important infrastructure to strengthen the westward connection of the Ningbo Metropolitan Area with the outside world.
Convenient transportation conditions are an important support for the development of leisure tourism, and the Jintai high-speed railway is not only an economic transportation link, but also a bridge for tourism cooperation, and an important business card to improve the quality of tourism and leisure along the line and enhance the attractiveness of tourism.
Jintai high-speed railway can greatly improve the comprehensive traffic conditions along the line, realize the organic docking of tourism resources in Taizhou, Jinhua and Ningbo, and directly connect to Qiandao Lake and Huangshan Scenic Area through Jinjian Railway, forming a high-quality tourism line, which will greatly enhance the accessibility, attractiveness and competitiveness of tourism resources, expand the tourism market and the development of tourism and leisure industry.
Jintai high-speed railway undertakes cross-line rapid passenger exchanges between Taizhou, Ningbo and southern Anhui, northern Jiangxi, Hunan and Hubei, southwest and northwest regions; It undertakes the rapid passenger exchange between Taizhou and western Zhejiang. According to the traffic volume**, the short-term and long-term Jintai high-speed railway will bear the proportion of cross-line passenger flow of 675% and 69% are regional high-speed railways dominated by cross-line passenger flow.
1) Implement major national development strategies and help build a new development pattern.
The "Outline for the Construction of a Transportation Power" proposes to basically build a transportation power by 2035, and by 2050, it will comprehensively build a transportation power that is satisfactory to the people, has strong guarantees, and is at the forefront of the world; The "Outline of the Advance Planning for Railways in the New Era of Transportation Power" proposes to build a developed high-speed rail network with the main high-speed railway corridor as the skeleton and the regional high-speed railway connection and extension.
The Jintai high-speed railway can greatly improve the coverage rate of the railway network along the line, which is an important measure to realize the construction of "developed fast network, perfect trunk network and extensive basic network" in the "Outline for the Construction of a Transportation Power", and is a strong practice of the goal of building a "national 123 travel traffic circle" proposed in the "Outline of the Advance Planning for the Railway of a Transportation Power in the New Era"; At the same time, the Jintai high-speed railway can improve the convenience and flexibility of the connection between the main axis and corridor, which is of great significance for the high-quality construction of a transportation power, the promotion of the railway of a transportation power, and the improvement of the main axis and corridor connectivity of the national comprehensive three-dimensional transportation network.
2) Promote the construction of Zhejiang's "Greater Bay Area, Big Garden, Big Channel, and Big Metropolitan Area" to promote the high-quality development of the regional economy.
Zhejiang Province proposed to fully implement the construction action plan of "Greater Bay Area, Big Garden, Big Passage and Big Metropolitan Area".
Among them, the construction of the "large channel" requires the construction of a one-hour traffic circle at the provincial level, a one-hour traffic circle at the municipal level, and an one-hour traffic circle at the urban level; The construction of the "metropolitan area" requires the acceleration of the construction of the rail transit system in the metropolitan area and the golden south wing of the integrated development of the Yangtze River Delta.
At present, the Ningbo metropolitan area is not closely connected with the surrounding metropolitan areas, especially the Jinyi metropolitan area; The fast track to the west is insufficient, and the external connection is not smooth.
The Jintai high-speed railway directly connects Ningbo and Jinyi metropolitan areas, forming a horizontal backbone channel for the westward exit of the central and eastern parts of Zhejiang, which is an important support for strengthening regional coordination and linkage and building a provincial one-hour traffic circle, and is also a link to strengthen the close connection of the "four cores" in the construction of the "metropolitan area" and promote the driving role of the core area of the metropolitan area.
3) Connect regional longitudinal high-speed rail corridors to strengthen the interconnection between the four major metropolises in Zhejiang.
The medium- and long-term layout plan of Zhejiang Province's railway network (2022-2050) plans to build a "five vertical and five horizontal" passenger transport network and accelerate the connection with the national "eight vertical and eight horizontal" high-speed rail network. As the connecting line between the Shanghai-Kunming Corridor and the coastal corridor, the main channel of the national "eight vertical and eight horizontal" high-speed railway, the Jintai high-speed railway is conducive to enhancing the connection between the Shanghai-Kunming corridor and the coastal corridor, expanding the attraction scope of the main corridor, and enhancing the competitiveness of the railway market.
In addition, the Jintai high-speed railway is a new horizontal passenger transport channel from the west of Taizhou and Ningbo, connecting the regional longitudinal coastal channel, the second coastal channel, and the Nanjing-Hangzhou-Wenzhou channel, and is also a high-speed railway connecting Ningbo and Jinyi metropolitan areas, which plays an important role in improving the regional road network, improving the connectivity and flexibility of the road network, and strengthening the interconnection between metropolitan areas.
4) Expand the tourism source market and build a beautiful economic corridor.
The population along the project is densely distributed and the tourism resources are abundant. Taizhou Tiantai is famous for the source of Buddhism and the beauty of mountains and rivers, and is the hermitage of Hanshanzi; The mountains and rivers of Jinhua are beautiful and wonderful, the national scenic spot Shuanglong Cave is well-known at home and abroad, and the provincial scenic spots Yongkang Fangyan, Wuyi Guodong - Longtan, Pan'an Huaxi, Dongyang Huadu - Pingyan, Tangxi Jiufeng Mountain and so on are good at winning.
The Jintai high-speed railway can realize the deep integration of tourism resources along the line, and at the same time use the Jinjian railway to directly connect Qiandao Lake and Huangshan Scenic Area, which is of great significance for building a beautiful economic transportation corridor, greatly improving the accessibility and overall competitiveness of tourism resources, and expanding the tourism source market and the development of tourism and leisure industry.
Jintai high-speed railway has the function of connecting the road network of the main channel of the national "eight vertical and eight horizontal" high-speed railway, connecting the Hangzhou-Shaoxing-Taiwan railway, Hangzhou-Wenzhou railway and connecting Ningbo and Jinyi metropolitan areas. It is of great significance to build a beautiful economic transportation corridor.
The functional orientation of the project is clear, the construction necessity is sufficient, and it should be implemented as soon as possible.
