New Metro (2020) 1(1): 55-59 SCIENCE POPULARIZATION In search of the Interchange King in Urban Rail Lines in China Rao Ya1,*, Xu Tianjie1 1Shanghai Rail Transit Industry Information Center, Shanghai, 201103, China. *Corresponding author: [email protected] © The Authors 2020 Article history: Received: 19-01-2020; Revised: 10-03-2020; Accepted: 25-03-2020 With the rapid development of the urban rail system Shanghai, and Guangzhou, which are in the ultra- in China, the scale of urban line network continues to large-scale urban rail transit network, and this result is expand. Passengers only need to transfer several times expected. Beijing Metro Line 10 has 16 interchange to reach all corners of the city by train. In the process stations. ranking first, and Shanghai Metro Line 4 has of forming the network with lines, the line nodes 15 interchange stations, ranking second, both of which become the transfer stations, and some lines are also are ring lines. The 3rd to 8th are all routes that pass taking on more and more transfer functions in the through the city center, with more than 30 stations. network. Based on the data in “China Urban Rail Therefore, there are more interchange stations. Transit Yearbook 2019” (as of the end of 2018), the Shanghai Rail Transit Industry Information Center is As demonstrated in figure 2, according to the statistics looking for the “Interchange King” among the 154 in “China Urban Rail Transit Yearbook 2019” (as of urban rail lines in China according to the Yearbook. the end of 2018), 11 urban rail lines in China has no interchange stations, while 45 lines have only one 1.

Only 13.6% of the lines has Viewing from the number of interchange stations, as more than 9 interchange stations. shown in figure 1, the top 8 lines are located in Beijing, 55 Ya & Tianjie (2020) New Metro (2020) 1(1): 55-59 Beijing Metro Line 10 Shanghai Metro Line 4 Shanghai Metro Line 12 Guangzhou Metro Line 3 Shanghai Metro Line 7 Shanghai Metro Line 13 Shanghai Metro Line 8 Shanghai Metro Line 10 Number of transfer stations Figure 1. Ranking of the number of interchange stations in urban rail lines in China (Top 8). Figure 2. Distribution of the number of interchange stations in urban rail transit lines in China 2. Viewing from the proportion of interchange changed, but the top 10 are still dominated by Beijing, stations Shanghai, and Guangzhou (6 lines in Beijing, 2 lines in Shanghai and Guangzhou respectively). Shanghai Due to the large difference in the operating length of Metro Line 4 ranks first with 57. 69% of interchange the lines, it is unfair to compare the number of stations, followed by Beijing Metro Line 2, 9, 13 and interchange stations only. Therefore, the following Airport Metro Line. It is worth noting that, among the sorting is done based on the proportion of the number lines in the “Ranking number of interchange stations” of interchange stations in all stations, as displayed in in Fig. 3, only Shanghai Metro Line 12 and Line 4 are figure 3. still on the list, which are the only two lines on the list with more than 25 stations in total. In this statistic, the contestants in the Top list have 56 New Metro (2020) 1(1): 55-59 Ya & Tianjie (2020) Number of non- Number of interchange interchange stations stations Beijing Metro Line 5 Shanghai Metro Line 4, 43.48% 57. 69% Beijing Metro Line 1, Beijing Metro Line 2, 55. 43.48% 56% Guangzhou Metro Line Beijing Metro Line 9, 1, 43.75% 53.85% Shanghai Metro Line 12, Beijing Metro Line 13, 43.75% 50.00% Guangzhou Metro Line Beijing Airport Metro 7, 44. 44% Line, 50. 00% Figure 3.

Viewing from the distribution density of “Interchange King” in urban rail transit lines in China! interchange stations Finally, the number of interchange stations per 10km in Beijing, Shanghai, Guangzhou, and Shenzhen In order to perform the evaluation more (TOP5) was calculated, as depicted in figure 5. comprehensively, the factor of line length was introduced to calculate and rank the number of As new lines in various cities continue to be put into interchange stations per 10km on average. This time, operation, the scale of the network continues to as exhibited in figure 4, Guangzhou APM Line ranks expand, and more and more interchange stations are first with 5. 1 ones per 10 km. However, because its bound to appear. According to the national line total length is only 3. 9km with 2 interchange stations, network plan approved in the end of 2018, interchange it is regarded as a special case. Shanghai Metro Line 4 stations accounted for approximately 26. 8% of all appears in the runner-up position once again. Beijing planned stations. It is foreseeable that the competition Metro Line 2, also a ring line, ranks third with a gap for the “Interchange King” will be more intense. of 0. 1, while Shenzhen Metro Line 7 ranks the 8th, However, this is only the prelude to China’s urban rail breaking the monopoly of Beijing, Shanghai, and transit entering the networked era. How to deal with Guangzhou. the huge challenges posed to the operation organization and risk control after the multi-line After competitions in three indicators, the result has network is formed is the problem that contemporary been released: Shanghai Metro Line 4 with one Chinese urban rail workers need to work hard to think, champion and two runner-ups, wining the title of deal with, and solve. 57 Ya & Tianjie (2020) New Metro (2020) 1(1): 55-59 Guangzhou APM Shanghai Metro Line 4 Beijing Metro Line 2 Beijing Metro Line 9 Guangzhou Metro Line 1 Beijing Metro Line 5 Beijing Metro Line 4 Shanghai Metro Line 12 Shenzhen Metro Line 7 Beijing Metro Line 1 Shanghai Metro Line 10 Figure 4.
