Municipal Meteorological Observatory experts said that the current long-term heat wave is relatively rare. “Historically, there have been more than 10 consecutive days of high temperatures in 1999. Since the high temperature warning, the high-temperature alarm has been sounded for 4 consecutive days and it has never happened. of".

Experts remind that citizens should try to avoid outdoor activities in the afternoon at high temperatures. In particular, old, weak, sick and young people should take protective measures in advance.

After the early morning peak and early evening peak error

(Reporter Qian Weihua) The hot weather allowed the public to choose a travel time that was “early and late”. Yesterday, the Municipal Traffic Management Bureau revealed that with the continued high-temperature attacks, the early morning peak of the city last week was half an hour ahead, and even from the early 6 o'clock onwards, the traffic flow increased significantly; the evening peak was obviously wrong after half an hour, 7:00 to 9:00. As a concentrated period of travel, the number of reported blockages in the two hours jumped by 188% compared with the previous week. There was a noticeable decrease in travel on weekends.

The traffic control department stated that drivers are prone to irritable in hot weather, encounter traffic jams or some traffic violations, and others may blurt out. Therefore, there is an increase in the number of "bucket cars" on the road surface, and vehicle crashes are also more prominent. On the other hand, the number of motor vehicles in this city is still rising sharply, aggravating the pressure on the road.

New statistics show that the city had a net increase of 14,000 motor vehicles last week and a net increase of more than 10,000 drivers. As of the 25th, the number of motor vehicles in the city reached 4.417 million, and the number of drivers reached 6.061 million.

Bus increase traffic capacity to open passengers

(Reporter Deng Hang) According to the new characteristics of the public traveling in the early days and evenings under the high-temperature conditions of the public, the bus group and the subway company adopted measures such as adjusting the capacity and increasing the number of temporary trains.

Yesterday, the bus group adjusted its capacity in time according to the characteristics of passengers traveling in hot weather. Measures have been taken to increase peak capacity and adjust trough intervals. Some key lines and large passenger routes also encrypt the morning and evening peak traffic intervals and minimize passenger waiting time.

As with ground traffic, underground traffic also exhibits the features of early morning and early afternoon peak faults. The eight lines operated by the MTRC have daily passenger traffic reaching 5.1 million to 5.3 million passengers for several days, while the daily passenger traffic has exceeded 5 million passengers on Friday.

The MTRC stated that in response to changes in the passenger flow of the summer transport, in addition to increasing temporary trains at the necessary time, in order to guarantee the order of subway operations and the personal safety of passengers, in the event of a large passenger flow shock, some stations will adopt short-term current limiting measures.

Glossary

High temperature heat wave

In China, high temperatures at or above 35°C are generally referred to as high temperatures, and high-temperature weather processes lasting more than 3 days are called high-temperature heat waves (or high-temperature heat). This year's last round of high-temperature heat waves in the city from July 2 to July 6, the current round from July 23, is currently expected to continue until July 30.

Sauna day

“Sauna days” refers to the weather that is stuffy and hot, and it is covered with sweat. In the "sauna days", since the moisture in the air has reached or nearly saturated, the moisture on the surface of the body does not easily evaporate, and therefore it is boring.

The No. 1 line non-air-conditioned vehicle starts renovation

The remaining 31 groups of 19 trains to be replaced with new cars will be converted into air-conditioned vehicles within 3 years

The continuous "sauna days" led many citizens to "abandoned" the ground transportation and transited to the subway, but some non-air-conditioned vehicles on Line 1 also allowed passengers to "heat up". The reporter learned yesterday from the Metro Department that all non-air-conditioned trains on the Metro Line 1 have already started renovation plans. Among them, 19 non-air-conditioned vehicles are expected to be replaced by new air-conditioned vehicles, and the remaining 31 non-air-conditioned vehicles will be converted into air-conditioned vehicles within three years.

New car replacement plan has been approved

The reporter learned from the relevant departments of the subway company that there are currently 70 groups of 6 trains on Line 1, of which 20 trains are air-conditioned vehicles that were on line before the Olympic Games to replace non-air-conditioned old cars that were purchased in the 1980s. 50 groups are non-air-conditioned vehicles. Of the 50 non-air-conditioned trains, a total of 19 groups of 114 trains were purchased in 1995 and have been used for 15 years. According to the rapid increase in passenger traffic on Line 1 and the overall performance of trains, the MTRC intends to replace these vehicles in advance and purchase a batch of new air-conditioned cars. The construction cost of each train reached more than 6 million, and the construction cost of 114 trains was as high as several hundred million yuan. At present, the plan for replacing the new car has already been approved and is waiting for approval from the relevant authorities.

Two fan cars complete renovation

At present, there are 31 sets of 186 non-air-conditioned vehicles put into use on the 1st line in the 1st line. This batch of vehicles did not reach the end of life. The subway company plans to transform this part of the car. It is very difficult to transform "fan cars". To install air-conditioning systems on trains, it is required to modify the cable lines within a limited space, and to ensure the running safety of existing trains. Since the body structure changes after the air conditioning system is installed, the signal system must be re-commissioned.

In recent days, two vehicles have been transformed. Trains must undergo a series of on-line comprehensive tests to carry passengers. After the test confirms that the train is successfully converted, it can be modified in batches according to the plan. Relevant person in charge of the Metro Corporation stated that it is expected that the vehicle transformation will be completed within two to three years.

>>Reporter Experience

In the "fan car" sweating

At 8 o'clock yesterday morning, the reporter crowded into the "fan car" on line 1 and wiped the sweat from his face with his hand. From Sihui East Station to Guomao Station, this movement was repeated more than ten times. Some passengers in the carriages have anxious expressions on their faces. From time to time, they use their hands to wind the air. Some are careful to avoid contact with other people's bodies to prevent them from sticking to the sweat, and some use their hands to lick their noses to try to avoid the odors around them. taste.

The train finally arrived at the Jianguomen station of the transfer station. The reporter quickly rushed down the subway. Due to the large number of people, passengers from the "fan car" are sweating and the makeup of the girl's face is shining. When some passengers got out of the car, they kept saying "Too hot, too hot."

Mr. Wang, waiting at the platform, saw a train with dark lights on the ground. He judged it to be a "fan car." He hesitated for a moment and didn't get on the train. "If you wait for more, you may encounter an air-conditioned car." Some passengers stated that the temperature difference between Line 1 and other subway lines is relatively large and it is easy to catch cold when transferring. “It would be good if Line 1 were replaced with air-conditioned vehicles.”

>>Responsive measures to open air conditioning before train operation

According to the introduction of the MTRC, under the current conditions, non-air-conditioned trains will increase the ventilation of the carriages, and at the same time require that 120 air-conditioned trains of 20 groups of Line 1 be put into operation in the morning and evening peak hours. Before the on-line operation of the train, air-conditioning was turned on 20 minutes in advance to keep the carriage cool. According to statistics, on weekdays, these 20 vehicles, such as all on-line operations, will account for 38% of all line operations on line 1.

In addition, after the transformation of the Metro Line 1 station, most of them have installed ventilation systems. In recent days, the ventilation system has been fully opened for use.

Sihui East station platform installed fan

In order to cope with the hot weather, 11 wall fans installed on the Subway Line 1 at Sihui East Station (in the direction of Sihuidong to Apple Orchard) were officially opened yesterday. This type of wall fan is a 500 mm diameter moving head fan mounted on a structural column in the waiting area of ​​the platform. As the ground station of the Metro Line 1 has not yet been installed with a ventilation system, the south and north sides of the four-way East Station of the ground station are obstructed by buildings and the ventilation is affected. The sultry conditions are even more serious. As the transfer station of Line 1 and Baton, the passenger flow at the peak of Sihui East Station was concentrated. In the near future, the continuous high temperature caused the station temperature to be as high as 37 degrees Celsius. According to the person in charge of the subway, the next step will be to install 16 more powerful fans at the station platform to speed up the air flow.
