·Long-distance double-sleeper bus has been banned from production and sales

Chinese designers have created "double-story sleeper buses" in order to satisfy the passengers who can sleep in the car and to arrange the number of passengers equivalent to the passenger cars in a limited space.

The sleeper bus not only solves the fatigue of passengers riding for a long time. In the eyes of bus companies, the increase in the number of passengers in double-decker buses is significantly higher than the increase in fuel, maintenance, crossing bridges, and personnel. In other words, the per-capita transportation cost of double-deck passenger cars is lower than that of single-layer passenger cars of the same length. As long as the attendance rate is guaranteed, the use of double-deck passenger cars can bring higher profits to passenger transport enterprises. However, in recent years, the frequent traffic accidents of long-distance double-story sleeper buses have attracted the attention of relevant state departments. What are the problems of double-decker buses and their problems?

At least 140 people were killed in 17 months

In the past 17 months, at least 6 double-sleeper bus accidents occurred in the country, and as many as 140 people were killed. However, looking back at previous reports, the majority of sleeper bus accidents are in the early hours of the morning. Yesterday, a major traffic accident in Yan'an territory occurred in the early morning. Most of the passengers in the car were in sleep state. There was only one door in the bus, and three survivors could only escape from the window.

According to incomplete statistics, there have been three major car accidents in this year's double-sleeper bus, and 94 people were killed. According to the statistics of the Traffic Management Bureau of the Ministry of Public Security, in 2011, there were 27 road traffic accidents involving more than 10 people in the country, including 8 inter-provincial long-distance passenger vehicles, and 14 occurred in the early morning and afternoon fatigue driving times. More than 800 kilometers of ultra-long-distance passenger transport lines operating passenger cars accounted for about 27.5% of the major accidents. Most of the long-distance buses are sleeper buses. According to statistics, the proportion of sleeper buses in China accounts for about 1% of bus passengers, but the death toll of passengers accounts for 10% of the deaths of bus accidents.

Prohibited production and sales in March this year

Li Xianneng of Guilin Bus Development Co., Ltd. has publicly issued a document saying that the designer of the sleeper bus has firmly grasped the design of the sleeper bus in two aspects, which is to satisfy the passengers to sleep, and to arrange the load of the passenger car in a limited space. The number of passengers, so the sleeper bus adopts the arrangement of the upper and lower double-layer arrangement and the longitudinal installation of the bedding. Compared with seat passenger cars and trains, sleeper buses improve the comfort of long-term rides and are a product that is very suitable for the needs of the Chinese passenger transport market.

It has been developed since the late 1980s and reached its peak in sales in 1996-1998. The sleeper bus has created a market performance of 7,200 vehicles per year. With the diversification of transportation methods, the market for sleeper cars is also shrinking year by year. After entering the year 2000, the sleeper bus market began to face increasing pressure. More importantly, the car interior environment of the sleeper bus was poor, the space was small, the ventilation was insufficient, and the sanitary conditions were poor. Because the sleeper bus adopts a double-layer layout, in fact, its passenger area is 1.5-1.7 times that of the seat passenger car, which is very dangerous.

However, the frequent accidents caused the Ministry of Industry and the Ministry of Public Security and the Ministry of Public Security to jointly issue the No. 632 document on December 31, 2011. Since it was confirmed that there was a safety hazard in the sleeper bus, it clearly stated: "From the date of the issuance of this notice, the passenger car in the sleeper Prior to the publication of the revision of the safety technical standards, the Ministry of Industry and Information Technology suspended the acceptance of the “News” for new products for sleeper buses. Since March 1, 2012, relevant enterprises should suspend production and sales of sleeper bus products, and the Ministry of Industry and Information Technology suspends all The sleeper bus product "Announcement", the traffic management department of the public security organ suspended the registration of the sleeper bus." This means that according to the normal retirement time of the sleeper bus, the operating sleeper bus on the passenger transport market will disappear in about 5 years.

The picture above shows the scene of the accident.

What are the hidden dangers of this unique double-story sleeper bus in China?

Some experts pointed out that the safety of the double-layer structure has always been a shadow of double-deck passenger cars. In the past, even if the double-deck passenger cars were known to have good profitability on certain routes, the traffic management bureaus in some places still dared not let go of the use of this model. The safety issue was their biggest concern.

Poor safety is the main reason why long-distance sleeper cars are “suddenly stopped”. This type of vehicle has a high center of gravity, narrow aisles, and many flammable materials. It is prone to accidents. Once an accident occurs, the losses are often very heavy. In fact, the sleeper bus for long-distance travel is a unique model in China, and there is no such model in foreign countries.

According to relevant persons from the Shanghai Transportation Management Department, the number of long-distance passenger sleeper cars in Shanghai has been decreasing year by year. What models and modes of transportation will be adopted for long-line operation in the future, and will ensure safety first and comfort according to relevant national requirements. And efficiency.

It is understood that the total number of long-distance sleeper buses currently operating in Shanghai is not large, but the long lines involved are relatively wide and the passenger traffic is stable. As of the end of last year, Shanghai has a total of 453 long-distance passenger sleeper cars registered, accounting for 20% of the total long-distance passenger vehicles, mainly from medium-long lines of 500 kilometers to 800 kilometers, and more than 2,000 kilometers to Guangdong and Sichuan. Extra long lines. Usually, each sleeper has 36 to 42 passengers and the vehicle height exceeds 3.8 meters.

According to industry insiders, from a professional point of view, the safety factor of sleeper buses is a little worse than that of seat cars, because the sleeper cars are relatively tall and there is no seat car stable. In addition, the corridors in the sleeper buses are relatively narrow and inconvenient to walk. Once an emergency occurs, it is difficult to evacuate quickly.

I am not allowed to supervise the car in the early morning

In fact, the frequent traffic accidents of long-distance double-story sleeper buses have attracted the attention of relevant state departments. On July 24, 2011, the Ministry of Transport decided to implement special supervision measures for sleeper buses, proposing that sleeper buses must be mandatory to install car video devices, and to implement temporary parking breaks from 2 am to 5 am.

However, the practice of temporarily stopping from 2 am to 5 am is not well managed. People in the industry have gradually reached a consensus: "The sleeper car is originally a transitional product under a special national situation, and the market demand is not large. From the principle of removing safety hazards, it is better to let it 'retire'."

Yan Zhenqing, deputy secretary-general of the China Highway Society Bus Branch, told reporters that the sleeper bus is an era product and not the main car in the current passenger transport market. Before the railway transportation can not meet the demand and the expressway network has not been completed, the transitional product of the sleeper bus has a significant effect. However, with the development of the Chinese passenger transport market, sleeper buses have “not weathered”. More importantly, under the concept of people-oriented and life-oriented, we need more rational and firm choices.

In addition, on September 1 this year, China will officially implement the 2012 edition of GB7258-2012 "Safety Technical Conditions for Motor Vehicle Operation", which is compared with the pre-revision, and puts forward higher and stricter technology for key vehicles such as passenger cars and school buses. standard. "GB7258-2012" stipulates that passenger cars with a length of 6 meters or more shall be equipped with an electromagnetic power main switch and a manual mechanical power-off switch. It is clarified that the passenger car with a length of 6 meters or more must be equipped with an emergency door and the safety glass of the passenger car emergency window. The selection requirements and emergency hammer requirements require that the school bus must be equipped with a first aid kit.
