The Ministry of Railways questioned the attendance of high-speed trains

At 14:57 yesterday, Beijing South Railway Station and some trains on the Beijing-Shanghai high-speed railway also had more than one ticket (green word display) for sale.

Netizens questioned the Beijing-Shanghai high-speed rail attendance rate of 107%; the Ministry of Railways explained that more than 100% is not necessarily overstretched because “the seats can be reused”.

In response to doubts about whether the "Beijing-Shanghai high-speed train operating rate of one month's attendance is 107%" is true on the Internet, relevant personnel of the Ministry of Railways responded yesterday that the attendance rate of more than 100% is not necessarily overstretched, and announced the calculation of the train occupancy rate of the Ministry of Railways. Method.

Netizens questioned

High-speed rail attendance rate of 107%?

The day before yesterday, the Ministry of Railways released a website. As of July 31, the Beijing-Shanghai high-speed rail network has operated 5,542 telecom trains for a month, with an average of 179 trains per day; it has transported 5.259 million passengers, averaging 170,000 people per day, with an average attendance rate. 107%.

The netizen “JungleGym” made a Weibo comment that every time I sit on a high-speed rail (less than 50 times) I have empty seats, and the Shanghai-Nanjing high-speed rail will be full at weekend peaks. I have never seen any passengers in the carriage. I wondered where does the 107% data come from?

The netizen “Look at 123” said, “I was surprised to see this news. I don’t know how this “average attendance rate” is calculated. When I took the G124 train on July 26, I didn’t see it that way. In the second-class seats, no more than 30% of seats are seated, there are fewer first-class seats, and there are only 3 seats in the business seat.”

The Ministry of Railways responded

Over 100% attendance rate

According to the People's Daily report, the Ministry of Railways responded that the "train occupancy rate" refers to the ratio of the number of passengers boarding a ticket to the number of trains, which reflects the availability of train seats. The high-speed train stops halfway, passengers have the upper and lower seats, and the seats are reusable, so attendance rates of more than 100% are not necessarily overstretched.

Last year, some outsiders also questioned that the Ministry of Railways' data on "average attendance" is different from passengers' feelings. At that time, the Ministry of Railways explained that China’s railway transportation statistics have been informatized and that the number of passengers buying tickets for each train is generated by computer statistics and is accurate and reliable. The reason why passengers feel different about the attendance rate is mainly due to the fact that daily, monthly and annual train attendance is an average number, and the attendance rate of each train is very uneven.

According to reports from the media last year, the attendance rate of Shanghai-Nanjing high-speed rail reflected by some travelers was so high. The question of why passenger compartments were often empty when they were riding was questioned by the relevant person in charge of the Ministry of Railways. First, the train attendance is an average, different The time attendance rate of trains is very uneven; secondly, when the high-speed rail tickets are sold, all the tickets will not be sold out at the starting station, and some seats will be reserved for the intermediate stations to ensure fairness. Therefore, there will also be empty carriages found on the train. phenomenon.

The Ministry of Railways announces the formula for calculating the attendance rate

Train occupancy rate = number of passengers boarding tickets/training capacity of passenger trains for example: The CRH3C EMU is used as an example. The train has a capacity of 556 passengers. If a Shanghai-Nanjing train arrives in Shanghai, there will be 480 people buying tickets on the train in Shanghai. The attendance rate was 480/556=86%. If it is not a direct train, the car has 480 people on the train in Shanghai, 400 people get off at the stop in Suzhou, and another 100 people get on the train and sit down to the finish line. Even though it only has 180 people when it comes to Nanjing, it is The attendance rate should be calculated as (480+100)/556=104%.

Remarks: As the high-speed train stops halfway, the passengers have the upper and lower seats, and the seats can be reused. Therefore, the attendance rate exceeding 100% is not necessarily overstretched.

"The Ministry of Railways statistics are not objective"

Ye Qing, deputy director of the Bureau of Statistics of Hubei Province, believes that there are problems with the algorithm of the Ministry of Railways. There is water in it and it is not objective. From an economic point of view, its attendance and ticket income are also asymmetric. In the same way, passengers are also misunderstood. "The attendance rate of 107% sounds quite deaf, but in reality there are not so many people on the data."

Ye Qing proposed counting the effective attendance rate of trains. The specific formula is:

Effective attendance = valid mileage / seat miles.

Remarks: Effective mileage: The mileage of the train when the seat is taken; The seat mileage: The mileage of the train when the seat is vacant or when there are people. Effective attendance will not exceed 100%.

For example: According to the Ministry of Railways' example, if a direct train from Shanghai to Nanjing was opened, 480 people would buy a ticket in Shanghai. The attendance rate was 480 people x 300 km/ 556 people x 300 km = 86%.

If it is not a direct train, the car has 480 people on the train in Shanghai, 400 people get off at the stop in Suzhou, and another 100 people get on the train and sit down to the finish line. When it comes to Nanjing Station, the car has only 180 people. The effective attendance rate of the brake is = [(400 persons × 100 km) + (80 persons × 300 km) + (100 persons × 200 km)]/ 556 persons × 300 km = 50.36%.

Remarks: It is understood that the total length from Shanghai to Nanjing is 300 kilometers, and that from Shanghai to Suzhou is about 100 kilometers.

Beijing South Railway Station started at a rate of over 60%

Yesterday, our reporter selected the G141 and G17 twice Beijing-Shanghai high-speed trains to calculate the initial attendance rate of the Beijing South Railway Station.

At Beijing South Railway Station, there are two ticket gates for each train. A passenger for 1-8 cars enters the station and a passenger for 9-16 cars enters the station.

Yesterday afternoon, according to statistics, the number of G141 and G17 ticket gates entering the station was 640 and 634, respectively, and their trains were 1028 and 1,005 respectively. Dividing the number of pit stops by the number of trains, the attendance rates of G141 and G17 at the time of their departure yesterday were 62.26% and 63.08%.

Yesterday, Ms. Tang, who was on the G37 train, said that her 15 cars were not empty seats. “The front of the car is full, and the back of the car is a first-class seat. There is no one.”

After rough statistics, Ms. Tang introduced that there are more passengers on and off in Jinan and Xuzhou. "I was from Xuzhou. I figured about it. I got off the train and got 18 people. There are about 15 people in the front and about 15 to 20 other cars. The number of people on the train is almost flat."
