Free inquiry service is provided to 1.6 billion mobile phone users. Mobile phone users can use the service to check all the cities and towns they have visited in the previous 14 days.
Run length encoding
Run length encoding (RLE), also known as run length encoding, run length encoding, variable length encoding, etc., is a kind of statistical encoding. Its main technique is to detect repeated sequences of bits or characters and replace them with their occurrences. It is more suitable for encoding binary images.
But it is not suitable for compressing continuous tone images, such as photos of daily life. To achieve better compression, stroke encoding is sometimes combined with some other encoding methods.
This compression encoding technology is quite intuitive and economical, and the algorithm is quite simple, so the decompression speed is very fast. rle compression encoding is particularly useful for computer-generated graphics images and is very effective at reducing storage capacity.
Freeway
Freeway, referred to as "Freeway", is a road designed for cars to travel at high speeds. Highways have different regulations in different regions, different eras, and different scientific and academic fields.
According to my country's "Highway Engineering Technical Standards" (JTG B01-2014), expressways are multi-lane expressways designed for cars to travel in separate directions and lanes, and all entrances and exits are controlled. The annual average daily design traffic volume of the expressway should be more than 15,000 small passenger cars, and the design speed should be 80 to 120 kilometers per hour.
As of December 28, 2018, China’s total highway mileage has reached 140,000 kilometers, ranking first in the world.
On May 10, 2019, at the regular policy briefing of the State Council of China, according to Dai Dongchang, Vice Minister of the Ministry of Transport, we will strive to basically eliminate toll stations at provincial boundaries on national highways by the end of 2019 and achieve non-stop Quick charges.
On April 28, 2020, the Ministry of Transport of the People's Republic of China issued the "Announcement on the Resumption of Toll Highway Toll Collection". From 0:00 on May 6, toll collection approved in accordance with the law will Will highways resume toll collection (including toll bridges and tunnels)? By the end of 2020, my country’s total highway mileage will be 5.1981 million kilometers, including 161,000 kilometers of expressways.
Hundred-kilometer traffic jam on Beijing-Tibet Expressway
Beijing-Tibet Expressway (formerly Badaling Expressway), as the main road connecting Beijing to Lhasa and other major cities in the northwest, bears a huge daily traffic pressure. Especially during holidays and special weather conditions, extremely serious traffic jams are prone to occur in various sections of the Inner Mongolia section.
Especially in 2010 and 2011, the length of the traffic jam exceeded 120 kilometers, so it was called the "100-kilometer traffic jam on the Beijing-Tibet Expressway."
